classpath problem with custom task

[Michelle Lin <mc...@yahoo.com>]

Hi experts,

I'm having strange classpath problem with custom task.
The ANT version I use is:
Apache Ant version 1.7.0 compiled on December 13 2006
and the JAVA version is 1.6

I have a java class XYZ.java that calls JMX client APIs to get mbean server and then get the mbean and invoke the operation on the mbean.

To invoke this class, I need two jars: x1.jar and wljmxclient.jar.
I defined following <path>:

     <path id="task.class.path">
        <pathelement location="..../x1.jar"/>
        <pathelement location="...../wljmxclient.jar"/>
      </path>
      <property name="tasks.class.path" refid="tasks.class.path"/>

Using this <path> definition and invoking XYZ class directly works fine:

<target name="testme">
   <input message="...." addproperty="host"/>
   ...
   <java classname="....XYZ", fork="true">
      <classpath refid="tasks.class.path"/>
      <arg value="..."/>
      ...
   </java>
</target> 

I have following message:
-------
-------------
[java] Connecting to: service:jmx:t3://<host>:<port>/jndi/weblogic.management.mbeanservers.runtime

BUILD SUCCESSFUL
------------------ 
Then I write a custom task XYZTask.java that gathers and validates user inputs, and calls XYZ class to do the same thing. This XYZTask.java is also in x1.jar. And I have following definition:

<taskdef name="myTask" classname="...XYZTask">
         <classpath>
            <pathelement path="${tasks.class.path}"/>
         </classpath>
</taskdef>
<target name="testme">
   <input message="...." addproperty="host"/>
   ...
   <myTask host="${host}" .../>
</target>

And I'm seeing following error:
-------------------------------
 [myTask] Connecting to: service:jmx:t3://<host>:<port>/jndi/weblogic.management.mbeanservers.runtime
[myTask] java.net.MalformedURLException: Unsupported protocol: t3
[myTask]      at javax.management.remote.JMXConnectorFactory.newJMXConnector(JMXConnectorFactory.java:327) 
...
-----------------------

This seems to me the "wljmxclient.jar" is not in the classpath when XYZ class is invoked.

Anything wrong with what I'm doing?

Thank you in advance for any suggestions/tips...
