The data data source unbound problem was solved when I decided to stick to the defaultDS. But now I am having a problem of deploying and .ear application. Below are the persistence.xml, component.xml. .ds.xml and the stack trace. I will send the stack trace for the earlier challenge later. Thanks 1.
