Alright, I am back.

So I tried with your persistence.xml - and it works! It's the extra information (xmlns, xsi) that did the trick because I did have the name specified in my original persistence.xml. I gotta figure out what that extra bit does.

Anyhow, moving on, I tried to run the Client. But the JVM is complaining that the class cannot be found. Now I have a question regarding this. Does the JVM look for Client.class in the EJB-JAR file or the directory where the classes had been generated and placed during compilation?  

Just to refresh, my directory structure looks like this:

build.xml
src/main/java/org/rij/*.java 
src/main/resources/META-INF/persistence.xml
src/main/resources/jndi.properties

target/classes/org/rij/*.class (all of the class files)
target/classes/META-INF/persistence.xml
target/mojo.jar 

Also. the part of build file that runs the client is as follows:

  | 	<target name="run.client" depends="ejbjar">
  | 	  <java classname="Client" fork="yes" dir=".">
  | 	    <classpath refid="classpath"/>
  | 	  </java>
  | 	</target>
  | 

Since the classpath is important, here is the relevant part of the build file that sets the classpath. 

  | 	<property environment="env"/>
  |         <property name="src.dir" value="${basedir}/src/main/java"/>
  |         <property name="src.resources" value="${basedir}/src/main/resources"/>
  |         <property name="jboss.dir" value="${env.JBOSS_HOME}"/>
  |         <property name="jboss.deploy.dir" value="${jboss.dir}/server/default/deploy"/>
  |   	<property name="target.dir" value="${basedir}/target"/>
  |   	<property name="target.classes.dir" value="${basedir}/target/classes"/>
  |   	<property name="common.lib.one" value="C:/opt/jboss-5.0.0.GA/common/lib"/>
  |   	<property name="common.lib.two" value="C:/opt/jboss-5.0.0.GA/client"/>
  | 
  | 	
  | 	
  | 	<!-- Next, specify where the client app is. client-config which has JNDI properties -->
  |         <path id="classpath">
  |            <fileset dir="${common.lib.one}">
  |               <include name="*.jar"/>
  |            </fileset>
  |            <fileset dir="${common.lib.two}">
  |               <include name="*.jar"/>
  |            </fileset>
  |            <pathelement location="${target.dir}"/>
  |            <pathelement location="${target.classes.dir}"/>
  |         </path>	
  | 

The second pathelement tag shows the exact location of the class, in case the JVM looks for the class file specifically. If instead the EJB-JAR is used, then I have not explicitly mentioned that. But my assumption is that the deploy directory in default server is automatically scanned?
