This script will download all the necessary binaries, build [[Netbinox]] bits and create an [[netbeans:NBM|NBM file]] and update center that can be installed into any [[NetBeans]] IDE or application. Alternatively you can download the NBM binary and archive with sources directly from the [http://hudson.apidesign.org/job/netbinox daily builder] or you can even build [[ZIP]] file with whole application:
-
# cd netbinox

-
# ant
+
<source lang="bash">
 +
$ ant build-zip
 +
</source>
-
This will create a [[ZIP]] file in ''dist'' directory with [[Netbinox]] IDE - e.g. [[NetBeans]] platform and IDE ready to empower [[Equinox]]. Alternatively you can download the binaries directly from the [http://hudson.apidesign.org/job/netbinox daily builder].

Time to create your first bundle or module! Choose from menu ''File/New Project'' and select [[OSGi]] bundle. New project is created and added into the already existing suite.

My favourite one is '''org.eclipse.mylyn.bugzilla.core'''. Add it into the list of dependencies of your bundle. Finish the dialog, select package in your project and create a class. Start to code and you can find classes from the bugzilla.core bundle. Refer to them, use them. Small example:

Before NetBeans 7.1 and After

Prior to NetBeans 7.1 the Netbinox was a separate component hosted in the apidesign Hg repository (under GPL license), but since NetBeans 7.1 the Netbinox is integral part of NetBeans (under more liberal NetBeans licenses).

It is easy to start!

Here is an old (but working) tutorial to use the standalone GPL licensed Netbinox. You can either build the GPL sources of the bridge between NetBeans and Equinox yourself or download the binaries.

To build from the sources you need JDK6: 

$ hg clone http://source.apidesign.org/hg/netbinox
$ cd netbinox
$ ant

This script will download all the necessary binaries, build Netbinox bits and create an NBM file and update center that can be installed into any NetBeans IDE or application. Alternatively you can download the NBM binary and archive with sources directly from the daily builder or you can even build ZIP file with whole application: 

$ ant build-zip


Execute!

Now it is time to start the system. You can do it via Ant by running 

$ ant run

This will start the NetBeans Platform together with Equinox OSGi container.

Empower Mylyn

Download our sample application that uses Mylyn (written as set of OSGi bundles) to connect to Bugzilla. 

$ hg clone http://source.apidesign.org/hg/netbinox-mylyn-sample

The root of the sources contains folder eclipse which contains some OSGi JAR libraries in raw form - e.g. just copied from Eclipse installation. The first thing to help Netbinox to use them is is to clusterize them. This can be done manually using

Code from platform.xml:
See the whole file.

<target name="convert">
    <ant antfile="${harness.dir}/suite.xml" target="clusterize">
        <property name="cluster" location="../eclipse"/>
        <property name="includes" value="modules/*.jar"/>
    </ant>
</target>
 

which produces bunch of XML configuration files in the config/Modules directory. These help Netbinox recognize bundles present in each cluster. This is common output of that Ant target: 

clusterize:
    [mkdir] Created dir: /netbinox-mylyn-sample/eclipse/config/Modules
[createmodulexml] Autoload modules: [org.apache.commons.codec, org.apache.commons.httpclient, org.apache.commons.lang, org.apache.commons.logging, org.eclipse.core.contenttype, org.eclipse.core.jobs, org.eclipse.core.net, org.eclipse.core.runtime, org.eclipse.equinox.app, org.eclipse.equinox.common, org.eclipse.equinox.preferences, org.eclipse.equinox.registry, org.eclipse.equinox.security, org.eclipse.mylyn.bugzilla.core, org.eclipse.mylyn.commons.core, org.eclipse.mylyn.commons.net, org.eclipse.mylyn.tasks.core]

However due to intricate build script setup this shall not be necessary. Just open the suite in your new unzipped the Netbinox IDE and run it.

Listen to ScreenCast

You can either follow the instructions written on this page, or if you wish, you can also listen and watch me and Geertjan demonstrating and discussing the power of Mylyn, NetBeans and the common ground in the following screen cast:


Develop with Mylyn

The next step is to use the Netbinox IDE and open mylyn-suite project (which is the next directory in the sample along the eclipse one). If you open the project customizer you can verify that there is a cluster called eclipse which enlists all the modules prepared in the previous step.

The application consists of two subprojects. One produces a NetBeans module that depends on OSGi bundles. Here is a dependency excerpt from the project.xml configuration file:

Code from project.xml:
See the whole file.

<module-dependencies>
    <dependency>
        <code-name-base>org.eclipse.core.runtime</code-name-base>
        <build-prerequisite/>
        <compile-dependency/>
        <run-dependency>
            <specification-version>3.5.0</specification-version>
        </run-dependency>
    </dependency>
    <dependency>
        <code-name-base>org.eclipse.equinox.common</code-name-base>
        <build-prerequisite/>
        <compile-dependency/>
        <run-dependency>
            <specification-version>3.5.1</specification-version>
        </run-dependency>
    </dependency>
    <dependency>
        <code-name-base>org.eclipse.mylyn.bugzilla.core</code-name-base>
        <build-prerequisite/>
        <compile-dependency/>
        <run-dependency>
            <specification-version>3.2.2</specification-version>
        </run-dependency>
    </dependency>
    <dependency>
        <code-name-base>org.eclipse.mylyn.commons.net</code-name-base>
        <build-prerequisite/>
        <compile-dependency/>
        <run-dependency>
            <specification-version>3.2.0</specification-version>
        </run-dependency>
    </dependency>
    <dependency>
        <code-name-base>org.eclipse.mylyn.tasks.core</code-name-base>
        <build-prerequisite/>
        <compile-dependency/>
        <run-dependency>
            <specification-version>3.2.2</specification-version>
        </run-dependency>
    </dependency>
    <dependency>
        <code-name-base>org.openide.util</code-name-base>
        <build-prerequisite/>
        <compile-dependency/>
        <run-dependency>
            <specification-version>8.0</specification-version>
        </run-dependency>
    </dependency>
</module-dependencies>
 

And it contains regular Swing action that can use Mylyn APIs to connect to some Bugzilla:

Code from TestBugzilla.java:
See the whole file.

TaskRepository repository = new TaskRepository("bugzilla", repoURL);
 
TaskRepositoryManager trm = new TaskRepositoryManager();
BugzillaRepositoryConnector brc = new BugzillaRepositoryConnector();
 
trm.addRepository(repository);
trm.addRepositoryConnector(brc);
 
String url = "/buglist.cgi?" +
            "query_format=advanced" +
            "&short_desc_type=allwordssubstr" +
            "&limit=5";
IRepositoryQuery query = new RepositoryQuery(
    repository.getConnectorKind(), ""
);
query.setUrl(url);
final List<TaskData> collectedData = new ArrayList<TaskData>();
TaskDataCollector collector = new TaskDataCollector() {
    public void accept(TaskData taskData) {
        collectedData.add(taskData);
    }
};
NullProgressMonitor nullProgressMonitor = new NullProgressMonitor();
brc.performQuery(
    repository, query, collector, null, nullProgressMonitor
);
 

This demonstrates how the system launches both the traditional NetBeans Runtime Container as well as Equinox. Both cooperate, start their own modules/bundles and provide them with their usual environment. Moreover there is a bridge (more about that is explained in Netigso article) around helping them mutually communicate with each other.

Develop OSGi!

The previous example shown how to develop a NetBeans module. However sometimes it is preferable to create an OSGi. For example when one needs to deal with BundleContext, it is necessary to create an OSGi bundle.

Nothing is simpler. One just need to change the manifest to contain Bundle-SymbolicName and the the Netbinox IDE generates an OSGi bundle automatically: 

Bundle-Activator: org.apidesign.listbundles.Installer
Bundle-SymbolicName: org.apidesign.listbundles
Bundle-Version: 1.0
Import-Package: org.osgi.framework
OpenIDE-Module-Layer: org/apidesign/listbundles/layer.xml
OpenIDE-Module-Localizing-Bundle: org/apidesign/listbundles/Bundle.properties

Then one can create an OSGi activator, remember the context:

Code from Installer.java:
See the whole file.

public class Installer implements BundleActivator {
    static BundleContext bc;
 
    public void start(BundleContext c) throws Exception {
        bc = c;
    }
 
    public void stop(BundleContext c) throws Exception {
    }
}
 

And create another Swing action to list all the activated OSGi bundles:

Code from ListBndsl.java:
See the whole file.

public final class ListBndsl implements ActionListener {
    public void actionPerformed(ActionEvent e) {
        StringBuilder sb = new StringBuilder();
        for (Bundle b : Installer.bc.getBundles()) {
            if (b.getState() != Bundle.ACTIVE) {
                continue;
            }
            sb.append(b.getSymbolicName());
            sb.append("\n");
        }
        DialogDisplayer.getDefault().notify(
            new NotifyDescriptor.Message(sb)
        );
    }
}
 

The following picture shows the output of such action demonstrating that NetBeans and Equinox really run together:
