Geertjan — Code Generator SPI Officially Available

The Code Generation SPI consists of two interfaces. The CodeGenerator implementations registered for various mime types serve for creating code snippets and inserting them into documents on the Insert Code editor action invocation. The CodeGeneratorContextProvider implementations registered for the mime types could provide the respective CodeGenerators with an additional context information.

Fine. What does all that mean? Firstly, interestingly, it means that the CodeGenerator class (and its supporting classes) are now officially supported and are exposed to the NetBeans API Javadoc. So, read the description to get an overview of it all.

Secondly, guess what? You can create code generators for any MIME type you want. So, you could add one/more to your HTML files... such as here:

So, the above appears when I press Alt-Insert in an HTML source file. What happens when I select the code generator item is up to me (i.e., the implementor of the API). In the case of Java source files, you can make use of the rather cool (though very cryptic) Retouche APIs. Let this document be your friend. I have found it pretty tough going, but gradually things become clear. Below, step by step, is my first implementation of a code generator. In the process, you'll see the Retouche APIs in action.

1. Get a very recent post 6.1 development build and create a new NetBeans module.

2. Set dependencies on Editor Library 2, Javac API Wrapper, Java Source, and Utilities API.

3. Let's start very gently:

   import java.util.Collections;
   import java.util.List;
   import org.netbeans.spi.editor.codegen.CodeGenerator;
   import org.openide.util.Lookup;
   
   public class HelloGenerator implements CodeGenerator {
   
       public static class Factory implements CodeGenerator.Factory {
   
           @Override
           public List create(Lookup context) {
               return Collections.singletonList(new HelloGenerator());
           }
       }
   
       @Override
       public String getDisplayName() {
           return "Hello world!";
       }
   
       @Override
       public void invoke() {
       }
       
   }

4. Register it in the layer.xml file like this, in other words, register the Factory that you see in the Java code above:

   <folder name="Editors">
       <folder name="text">
           <folder name="x-java">
               <folder name="CodeGenerators">
                   <file name="org-netbeans-modules-my-demo-HelloGenerator$Factory.instance"/>
               </folder>
           </folder>
       </folder>
   </folder>

5. Now you're good to go. Just install the module and invoke the code generators as always, Alt-Insert, and then you'll see the new one added:

   

6. OK, now we'll do something useful. We'll start by getting the JTextComponent from the Lookup. That JTextComponent is the Java editor and if we use getText, we can get the text of the Java editor. We can also get the Document object, which is all that we need in order to get the JavaSource object, via JavaSource javaSource = JavaSource.forDocument(doc);, which, in turn, is our entry point into the Retouche APIs. So, here we go:

   public class HelloGenerator implements CodeGenerator {
   
       private JTextComponent textComp;
   
       private HelloGenerator(JTextComponent textComp) {
           this.textComp = textComp;
       }
   
       public static class Factory implements CodeGenerator.Factory {
   
           public List create(Lookup context) {
               Item textCompItem = context.lookupItem(new Template(JTextComponent.class, null, null));
               JTextComponent textComp = textCompItem.getInstance();
               return Collections.singletonList(new HelloGenerator(textComp));
           }
       }
   
       @Override
       public String getDisplayName() {
           return "Hello world!";
       }
   
       @Override
       public void invoke() {
       }
       
   }

   I don't know whether the above is the optimal way of doing this, but at the end of the day we now have a JTextComponent. In the next part, I've simply taken code from the Java Developer Guide, referred to earlier, and implemented the invoke exactly as described there, so see that document in order to understand the code below:

7. Define the invoke method like this, which as stated above is completely taken from the Java Developer Guide:

   @Override
   public void invoke() {
       try {
           Document doc = textComp.getDocument();
           JavaSource javaSource = JavaSource.forDocument(doc);
           CancellableTask task = new CancellableTask() {
               @Override
               public void run(WorkingCopy workingCopy) throws IOException {
                   workingCopy.toPhase(Phase.RESOLVED);
                   CompilationUnitTree cut = workingCopy.getCompilationUnit();
                   TreeMaker make = workingCopy.getTreeMaker();
                   for (Tree typeDecl : cut.getTypeDecls()) {
                       if (Tree.Kind.CLASS == typeDecl.getKind()) {
                           ClassTree clazz = (ClassTree) typeDecl;
                           ModifiersTree methodModifiers = make.Modifiers(Collections.singleton(Modifier.PUBLIC), Collections.emptyList());
                           VariableTree parameter = make.Variable(make.Modifiers(Collections.singleton(Modifier.FINAL), Collections.emptyList()), "arg0", make.Identifier("Object"), null);
                           TypeElement element = workingCopy.getElements().getTypeElement("java.io.IOException");
                           ExpressionTree throwsClause = make.QualIdent(element);
                           MethodTree newMethod = make.Method(methodModifiers, "writeExternal", make.PrimitiveType(TypeKind.VOID), Collections.emptyList(), Collections.singletonList(parameter), Collections.singletonList(throwsClause), "{ throw new UnsupportedOperationException(\"Not supported yet.\") }", null);
                           ClassTree modifiedClazz = make.addClassMember(clazz, newMethod);
                           workingCopy.rewrite(clazz, modifiedClazz);
                       }
                   }
               }
               @Override
               public void cancel() {}
           };
           ModificationResult result = javaSource.runModificationTask(task);
           result.commit();
       } catch (Exception ex) {
           Exceptions.printStackTrace(ex);
       }
   
   }

8. Excellent. At this point, check that you have this impressive list of import statements:

   import com.sun.source.tree.AnnotationTree;
   import com.sun.source.tree.ClassTree;
   import com.sun.source.tree.CompilationUnitTree;
   import com.sun.source.tree.ExpressionTree;
   import com.sun.source.tree.MethodTree;
   import com.sun.source.tree.ModifiersTree;
   import com.sun.source.tree.Tree;
   import com.sun.source.tree.TypeParameterTree;
   import com.sun.source.tree.VariableTree;
   import java.io.IOException;
   import java.util.Collections;
   import java.util.List;
   import javax.lang.model.element.Modifier;
   import javax.lang.model.element.TypeElement;
   import javax.lang.model.type.TypeKind;
   import javax.swing.text.Document;
   import javax.swing.text.JTextComponent;
   import org.netbeans.api.java.source.CancellableTask;
   import org.netbeans.api.java.source.JavaSource;
   import org.netbeans.api.java.source.JavaSource.Phase;
   import org.netbeans.api.java.source.ModificationResult;
   import org.netbeans.api.java.source.TreeMaker;
   import org.netbeans.api.java.source.WorkingCopy;
   import org.netbeans.spi.editor.codegen.CodeGenerator;
   import org.openide.util.Exceptions;
   import org.openide.util.Lookup;
   import org.openide.util.Lookup.Item;
   import org.openide.util.Lookup.Template;

9. Now install the module again. Then open a Java source file. Let's say it looks like this:

   package org.netbeans.modules.my.demo;
   
   public class NewClass {
   
   }

   Press Alt-Insert anywhere in the source file, choose "Hello world!", and now you will see this instead of the code above:

   package org.netbeans.modules.my.demo;
   
   import java.io.IOException;
   
   public class NewClass {
   
       public void writeExternal(final Object arg0) throws IOException {
           throw new UnsupportedOperationException("Not supported yet.");
       }
   
   }

Hurray. You have your first code generator. In an HTML source file, the above invoke method could be as simple as this, which would print <h2>hello</h2> at the caret:

@Override
public void invoke() {
    try {
        Caret caret = textComp.getCaret();
        int dot = caret.getDot();
        textComp.getDocument().insertString(dot, "<h2>hello</h2>", null);
    } catch (BadLocationException ex) {
        Exceptions.printStackTrace(ex);
    }

}

The very cool thing about these code generators is that you can keep typing, i.e., your fingers don't leave the keyboard in order to go to a menu item via the mouse, etc. You're typing as normal, then you press Alt-Insert, you select something, and then you go on typing. Being able to make your own contributions to the list of Java code generators (plus, being able to make them for other MIME types) is a really powerful enhancement to NetBeans IDE.

Sidharth — Installing OpenSSO (B4) on Glassfish

OpenSSO is a self-contained J2EE application and the installation is a breeze. Here's the detailed steps.

1.  Create a base directory. "/opensso_bits"

2.  Install GlassFish. If you already have GlassFish running, go to step-4.

3.  Create a GlassFish domain - "fam".

To Create new GlassFish domain.  
Create "/tmp/passfile" with following content,
AS_ADMIN_ADMINPASSWORD=adminadmin
AS_ADMIN_MASTERPASSWORD=changeit

Create glassfish domain with the following commandline
./asadmin create-domain --adminuser admin --passwordfile /tmp/passfile --portbase 7000 fam

4.  Start Glassfish instance and make the following changes to the instance on which opensso is being deployed (fam)

cd <GLASSFISH_HOME>/bin
./asadmin start-domain fam

./asadmin delete-jvm-options  --port 7048 --user admin "\\-client"
./asadmin create-jvm-options  --port 7048 --user admin "\\-server"

./asadmin delete-jvm-options  --port 7048 --user admin "\\-Xmx512m"
./asadmin create-jvm-options  --port 7048 --user admin "\\-Xmx1G"

5.  Important (Optional for first time opensso install on a system).

If you already have opensso deployed and configured on the GlassFish instance,

- Undeploy opensso (via GlassFish admin console)
- Delete the configuration directory, as used during the previous configuration. (e.g. rm -rf /opensso)
- Delete the Access Manager directory (Usually in the users home directory). (e.g. rm -rf /AccessManager)

6.  Restart the glassfish instance.

cd <GLASSFISH_HOME>/bin
./asadmin stop-domain fam
./asadmin start-domain fam

7.  Deploy OpenSSO on the Glassfish domain "fam".

- Go to Glassfish admin console. (http://<host>.<domain>:7048)
- Login as admin/adminadmin
- On left nav bar, click on "Web Applications"
- Click on "Deploy".
- Browse and locate opensso.war ( "/opensso_bits/opensso/deployable_war/opensso.war" )
- Under "General"
- Application Name - opensso
- Context Root - opensso

- Click "Ok"

8.  Go to the deoployed opensso instance.

- Under "Custom Configuration", select "Create New Configuration".
- General
- Password - <password for amadmin>
- Confirm Password - <same as above>

Server Settings (Most of the following are populated by the installer and can be left as it is.)

- Server URL - <e.g. http://sid.opensso.com:8080>
- Cookie Domain - <e.g. .opensso.com>
- Platform Locale - <e.g. en_US>
- Configuration Directory </openssoconfig>

Configuration Store - (e.g. Use all Defaults, as populated by installer).

- Data Store Type - <e.g. Embedded (Open DS)>
- Port - <e.g. 50389>
- Encryption Key - <e.g. as populated by installer>
- Root Suffix - <e.g. dc=opensso,dc=java,dc=net>

User Store Settings (e.g. Use Defaults, as populated by installer)

- Embedded.

Site Configuration (e.g. Use Defaults, as populated by installer)

- Will this instance be deployed behind a load balancer as part of a site configuration? <No>

Agent Information

- Default Agent [amldapuser]
- Password - <select password, should be different from the password for amadmin>
- Confirm - <same as above>

Click "Next".

Summary

Click "Create Configuration".

9.  You'll see a message "Configuration Complete", "Proceed to Login".

Click on "Proceed to Login"

10.  Login as amadmin with the corresponding password.

Roman Strobl — Foss Camp Prague

Quick note: I just did a presentation with Arseniy Kuznetsov (NetBeans director) about NetBeans at FOSS camp. It was kind of cool to demo Matisse in front of people like Mark Shuttleworth :) I think the demos were well received and we also had a discussion about getting NetBeans into Main Ubuntu repository (it is now available in Ubuntu Universe). There seems to be a potential for NetBeans to become a really popular IDE among Linux developers - we support many languages they use. The main missing language seems to be Python - and as you probably know Sun hired two Python/Jython developers to work on that - so the future of Python support in NetBeans is very bright.

FOSS Camp was an unconference, actually we were the only presenters who were using a projector (sorry about that but it would be hard to draw features of the IDE on a flipchart :). I wonder how many of the Ubuntu guys noticed I delivered my presentation on OpenSolaris (Gnome looks almost identical on Linux and OpenSolaris). It was nice for a change to visit an unconference, it definitely has a more "human" atmosphere with more 2-way communication than we see at typical conferences. Maybe it's time for NetBeans to organize some unconference as well? Just an idea.

Jimmo — Solaris chosen over Linux for better performance

It's nice to hear a success story, no matter how big or small, so I was pleased to see that Real Time Matrix Corp. had a pleasant surprise when the compared the performance Solaris 10 to Fedora.

Despite being a committed Linux environment, they decided to try out Solaris 10 while they had a T1000 on trial...and ended up feeling quite pleased with the result, claiming that Solaris 10 had "50 times the throughput" of the Fedora configuration.

For the full story, take a look at the online article.

Henry Jen — OpenAL on OpenSolaris

When I was asked to look at Project Wonderland a while back, first thing I would like to do is to run it on my laptop. But guess what? No audio support for me because I am running Solaris and JOAL is not available.

So I started by trying to build OpenAL on Solaris, and after some dig, I managed to get a patch to enable build on Solaris with Sun Studio 12. At JavaOne, I talked to Ken Russel, the rockstar who maintains JOAL and JOGL, and we think it would be great to bring JOAL to Solaris(Actually, there are quite a few build out there, Second Life client for Solaris, SFE, CSW).

The patch was not get into the upstream due to broken SVN, so we would like to revisit the possibility to get patch into upstream. Since I upgraded to OpenSolaris 2008.05, so I pulled the trunk, applied the patch, but autotools is giving me some craziness, so I use cmake build which goes out smoothly(I built cmake myself, which is pretty straightforward, we should really consider to add it into OpenSolaris).

Now I am ready to roll, however, there are two packages I need to install before I can successfully build solaris backend.

pfexec pkg install SUNWaudh SUNWgnome-common-devel

With this new patch, now OpenAL can be built as simple as following:

Henry Jen — autotools hell

I was very frustrated today with autotools when building OpenAL on OpenSolaris 2008.05. I finally decide to gave up and use cmake build system instead, which works very well. I think there is a reason why so many projects(good ones like KDE4, WireShark) are starting to adapt cmake, and maybe jxta-c should do that too.

So allow me dump the problems here, and hopefully some experts will shed lights for me. Note that I do try with other projects using autotools, for example, jxta-c is working OK, but not for OpenAL. Let's see what is going on:

/tmp/openal-trunk/OpenAL-Sample$ ./autogen.sh 

Can't exec "aclocal": No such file or directory at /usr/bin/autoreconf line 182.
Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 182.
Can't exec "automake": No such file or directory at /usr/bin/autoreconf line 183.
Use of uninitialized value in pattern match (m//) at /usr/bin/autoreconf line 183.
Can't exec "automake": No such file or directory at /usr/bin/autoreconf line 240.

Can't exec "aclocal": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 290.
autoreconf: failed to run aclocal: No such file or directory

OK, I think OpenSolaris should have a default symbolic link for aclocal and autoconf. Moved on.

Gees, the compiler environment is so screwed up that most test actually fails, and I cannot even tell whose fault it is. :-(

Orange and blue and green, actually. I could give you the flower names and so on but why bother, it’s just some blossoms and leaves, cheery stuff.

I think the leaves are as pretty as the flowers.

Bill Walker — The world's coolest customer...

My project manager brings in homemade cookies and muffins several times a week. The customer buys lunch, pizza on Tuesdays, and Jason's Deli sandwiches on Thursdays. The whole team (about 30 people) are invited out for a happy hour once a week, including dinner at one of the local eateries. Very cool customer, very cool work. Oh yeah, I'm here doing work.

I'm doing a provisioning project, using Jumpstart and the JET toolkit to model and test the provisioning of dozens of the new T52x0 CMT servers, implemented and provisioned on-demand through the N1 Service Provisioning System. This is a tight schedule project, so ZFS, LDOMs, and some other new functionality and features are being left until the next update to the environment. We are using Solaris Containers and the N1 Service Provisioning System though. In fact, each server on the application side will have 36 full root zones running the Sun Glassfish Enterprise Server and Sun Java System Web Server.

There, enough links to make any shareholder happy.

This project has been full of interesting challenges. Try deploying around 100 servers along with the deployment architecture in 60 days. Of course, there were some standards and policies in place, but the customer wanted to streamline things, and increase efficiencies in patching and systems management. Now throw in 36 full root zones (containers) in each system, with 6 filesystems each, all running on the internal disk drives with no external storage. Hmmm... This is getting complicated (and very snug). Oh yeah, we need to implement Live Upgrade, and make sure that the whole project is well documented, easy to manage, flexible and modular so that the next revision of the provisioning and systems infrastructure can evolve in a simpler and more organized set of projects.

I'll post some of the more interesting challenges, issues, resolutions, and creative solutions as this project develops. Never a dull moment, or an end to the opportunities to be creative with this project!

cheers!

jyrivirkki — Web Stack Road Trip

It's been very busy times lately so haven't had a chance to blog..

Thanks to everyone who came to my OpenSolaris AMP (slightly misnamed as it covered all of Web Stack) talk at CommunityOne last week.

Next week I will be at the Sun Tech Days conference in Mexico City again talking about OpenSolaris Web Stack. I hope to see some of you there!

scblog — DOM Inspector in Firefox Sidebar

In this entry I talked about how to show Google Talk in Firefox Sidebar. Using the same technique you can show the DOM Inspector in the Firefox Sidebar. That way you can get the DOM Inspector in the same window as the page you are inspecting.

 Here is how. Just create a bookmark like this:

and then invoke the bookmark. Then use the File:Inspect Window > menu item to select the window you are browsing in. You will see something like this

Unfortunately the Sidebar is not resizable. However this could be tweaked using the property overlay incantation overrding the flex attribute of the sidebar box. Also the popup dialogs to search for  nodes does not work. Once again some XUL overlay gimmickry could come handy here.

Useful? You decide.

Ryan Arneson — Using the X4500 as a Backup Disk-Cache

Marc Hamilton — What Is Our Most Popular Product This Month?

Sybase certainly thought so, they recently set a Guinness World Record for the world's largest database, over 1 PetaByte of data and over six trillion rows of transaction data. Now that is a big database. What server did they choose to set this world record with? Sun's M9000. OK, so most users of Sun's MySQL database may be more interested in a x4440 and a Guinness beer, I'm not sure there are any 1 PetaByte MySQL databases yet. But I wouldn't bet against MySQL moving into this range in the future. Meanwhile, lots of customers who need to run really large databases and other open systems applications are turning to the capabilities of Sun's M9000.

Congratulations to Sybase on their new world record! Now I think I'll grab my Guinness, the liquid one not the hardback.

Roger Dong yudong — 为地震死伤者祈祷

昨天我们公司的现场救助志愿者发回邮件的时候，公司里许多人哭了。不过令人欣慰的是，这次天灾以后我们看到了一个团结的民族，一个理性的民族，一个充满希望的国家和民族。我们看到了台湾同胞血浓于水的兄弟感情，得到了国际上的朋友的支持。我们甚至感染了那些以往对我们并不那么友好的一部分人。

死者已逝 - 为他们点一只蜡烛。天堂的路上，不再孤独。

（转一篇俄罗斯国家新闻网报道） 

中国不需要同情，中国需要理解；中国不需要安慰，中国需要支持。我们愿以杯水之力，尽寸尺之能，和中国人民站在一起。我们知道，一个总理能在两小时就飞赴 灾区的国家，一个能够出动十万救援人员的国家，一个企业和私人捐款达到数百亿的国家，一个因争相献血、自愿抢救伤员而造成交通堵塞的国家，永远不会被打 垮。

希望必将与中国同在。

让我们为生者祝福，为死者祈祷。中国，走好。

theaquarium — Scala's Lift on GlassFish v3

I'm beginning to think we "undersold" GFv3 TP2 when we called it a Technology Preview as pretty much anything we are throwing at it works! Check out Vivek's latest note on Scala Lift Framework. Starting with a Maven Archetype, it creates a Scala Lift project using a Derby database that can deploy on GFv3 and, with a small change it can use v3 tp2 embedded for ease of development through mvn glassfish:run. Neat!

Todd Fast — Applications for the Masses by the Masses: Why Engineers Are An Endangered Species

I did a session last week at JavaOne 2008 where I talked about how application development, and the role of application developers, is changing. Here's the abstract:

When we engineers normally think of applications, we think of elaborate technology that takes highly trained developers weeks, months, or years to develop and debug. But our days are possibly numbered. In this era of light-speed boom and bust, the demand for technology is higher than ever and engineers and their traditional development techniques simply can’t keep up. What’s needed is “disposable applications,” applications so quick and easy to write that they are cheaper to throw away than to maintain and which the increasing numbers of casual technologists can consume and even create themselves.

Fueling this demand in recent months has been the release of high-profile web platforms (such as Facebook, Ning, Meebo, and others) that increasingly enable nontechnical users to compose mashups and other social and situational applications out of widgets and RESTful-style web services, all built by use of lightweight technologies and composed right from the browser.

This session describes how these factors are coming together to produce a new paradigm of application development in which hordes of 16-year-olds are in charge and software engineers are overwhelmed by the flood of applications created by tech-savvy novices. It also examines the roles of high technology versus technology for the masses and shows that they are actually complementary and a boon to engineers and nonengineers alike.

...

I presented to about 500 people over two sessions on Wednesday and Friday, and despite the fact that I could not show a demo, it was a rapt audience. Since then, coverage has been popping up around the Web.

Here are slides and links to articles and other material:
