Packaging POF object class in a jar file

Question

I have the following issue packaging a POF class.
I have two POF classes which are defined in the package oracle.communications.activation.asap.ace;
1. Token.java
2. Asdl.java
For simplicity i package them in the coherence.jar along with the other nessary artifacts.
"tokens-pof-config.xml"
<?xml version="1.0"?>
<pof-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.oracle.com/coherence/coherence-pof-config"
xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-pof-config coherence-pof-config.xsd">
<user-type-list>
<!-- coherence POF user types -->
<include>coherence-pof-config.xml</include>
<!-- com.tangosol.examples package -->
<user-type>
<type-id>1001</type-id>
<class-name>Token</class-name>
</user-type>
<user-type>
<type-id>1002</type-id>
<class-name>Asdl</class-name>
</user-type>
</user-type-list>
<allow-interfaces>true</allow-interfaces>
<allow-subclasses>true</allow-subclasses>
</pof-config>
Then I startup the CacheServer it startsup fine. However when I invoke the POF classes from my weblogic artifacts I get the following error message.
<Oct 26, 2011 10:04:24 PM PDT> <Warning> <EJB> <BEA-010065> <MessageDrivenBean threw an Exception in onMessage(). The exception was:
(Wrapped) java.io.IOException: unknown user type: oracle.communications.activation.asap.ace.Token.
(Wrapped) java.io.IOException: unknown user type: oracle.communications.activation.asap.ace.Token
======================================================================================================================
If I however define the classes in the default package or no package instead of package oracle.communications.activation.asap.ace;
Keeping everything else the same everything works fine.
====================================================================================
What do I need to do to make this work if I am packaging my POF classes not in the default package ?

Answer 1

Hi JK,
Well i have modified my POF classes since then and now created a package for them before I was just playing around and had them defined in a default package.
Second Baby steps here, once I get things working by packaging things in the coherence.jar file I will create my own jar artifact and add it to class path. As it is I have classpath issues. ...
So as I mentioned earlier.
I created the oracle/communications/activation/asap/ace directory added my two POF classes to it and then repackaged the jar.
It returns this error!
2011-10-27 06:48:03.355/4.696 Oracle Coherence GE 3.6.0.4 <Error> (thread=main, member=1): Error while starting service "DistributedCache": (Wrapped) (Wrapped: error configuring class "com.tangosol.io.pof.ConfigurablePofContext") java.lang.NoClassDefFoundError: oracle/communications/activation/asap/ace/Token (wrong name: Token)
So any ideas ?

Token.java for example (Asdl.java looks very similar)
