What is JBOSS- “Empty name segment is not allowed for java” error

问题

I am newbee to JBOSS developement and tring to run a project from eclipse but I am getting "Empty name segment is not allowed for java" error. I know such error comes when our jndi resource name is empty but in such case it specifies as "env" and not "java" which is in my case. Posting my stacktrace below. I am using JBOSS 7.1 version.

I see one warning saying that JBAS011001: Could not resolve resource-env-ref java:/TransactionManager but dont think error is caused by it.

Please guide me. Thanks in advance.

I need to remove java:/ prefix from the datasources mentioned in standalone.xml. It got solved. Because in persistance.xml it was without that prefix.
