hi,
I am trying to use xa-datasource configuration for derby with my application deployed on JBoss 5.0.0GA(on Linux with jdk version 1.5). I asked this question from JCA forum and now since this looks like a JNDI problem, I am posting here as well. Sorry for the cross post.
Once deployed the below xa-configuration I am getting the exception: You are trying to use a connection factory that has been shut down (full stack trace is available below.).

Any help to fix the problem will be highly appreciated. Thanks in advance.

<datasources>
 <xa-datasource>
 <jndi-name>XADerbyDS</jndi-name>

 <!-- uncomment to enable interleaving <interleaving/> -->

 <isSameRM-override-value>false</isSameRM-override-value>
 <xa-datasource-class>org.apache.derby.jdbc.EmbeddedXADataSource</xa-datasource-class>

 <!-- path to the database. (${jboss.server.data.dir}${/}derby${/}default didn't work on win) -->
 <xa-datasource-property name="DatabaseName">derby/esb</xa-datasource-property>
 <xa-datasource-property name="User">esb</xa-datasource-property>
 <xa-datasource-property name="Password">esb</xa-datasource-property>
 <xa-datasource-property name="CreateDatabase">create</xa-datasource-property>

 <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
 <metadata>
 <type-mapping>Derby</type-mapping>
 </metadata>
 </xa-datasource>
</datasources>

The exception when using the above defined data source(I don't get any error while sever start up) as follows.

org.jboss.util.NestedSQLException: You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null.; - nested throwable: (javax.resource.ResourceException: You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null.)
