All,

In an effort to understand and implement a simple java plugin node, I wrote a simple java code and was able to compile it successfully. I am definitely sure that I am doing something wrong but am unsure about what

Steps I performed:

1) Created a Message flow Plugin node Project with Category as "Test" and Project Name as "com.ibm.test". Choose the default properties in the "Plug in Project Structure" and opted for "Create a blank plug-in project" in "Plug-in Code Generators view"

2) I can see the "com.ibm.test" in the package explorer. Added the External Jar file "<install-dir>/classes/jplugin". The Build Output Folder is set as "com.ibm.test/bin".

3) I created the "com.ibm.testpack" package and copied my *.java file manually in the "<workspace>\com.ibm.test\src\com\ibm\testpack" directory.

4) I compiled the java file manually by entering the command

Code:

[b]javac <workspace>/com.ibm.test/src/com/ibm/testpack/TestNode.java[/b]

5) I then created the jar file using the command

Code:

jar -cvf TestNode.jar <workspace>/com.ibm.test/src/com/ibm/testpack/

. As both the *.Java file and *.Class file are in the same directory both were added the jar file. Content of Jar file

Code:

TestNode.Java
TestNode.Class
Manifest.mf

6) I copied the jar file into the <install-dir>/jplugin directory

I got little confused as what to do at this stage and I ended up performing the below steps

7) I copied the complete "com.ibm.test" from <workspace> to "<install-dir>/eclipse/plugins/."

8 ) I stopped the broker and restarted. At this stage I can see the "Category" but I dont see any nodes listed under that.

here is how my plugin.xml look like

Code:

<?xml version="1.0" encoding="UTF-8"?>
<plugin id="com.ibm.test" name="com.ibm.test" version="1.0.0">


<requires>
<import match="equivalent" plugin="com.ibm.etools.mft.api" version="5.0.0"/>
<import match="equivalent" plugin="com.ibm.etools.mft.uri" version="5.0.0"/>
<import match="equivalent" plugin="org.eclipse.help" version="2.0.2"/>
<import match="equivalent" plugin="org.eclipse.ui" version="2.0.2"/>
<import match="equivalent" plugin="org.eclipse.swt" version="2.0.2"/>
</requires>
<runtime>
<library name="test.jar"/>
</runtime>


<extension point="org.eclipse.help.contexts">
<contexts name="HelpContexts.xml"/>
</extension>


<extension point="com.ibm.etools.mft.api.nodes"/>


<extension point="com.ibm.etools.mft.uri.pluginspace"/>
</plugin>

Any help is highly appreciated. Thanks in advance.

Hi,

you have to do a bit more than copying a class file to message brokers jplugin directory.
You find some examples by reading following redbook : http://www.redbooks.ibm.com/redbooks/SG246579.html or by checking the online documentation.
