Hello,
this 3-letter-attribut is something unclear to me. If you set a new datasource within management, then default is jta="false".
This description only states Enable JTA integration (only <datasource>)
Our JSF-project inside persistence.xml have
<xmlnode prop="abc">
<persistence-unit name="MyPU" transaction-type="JTA">
<jta-data-source>java:/My_DB_SRC</jta-data-source>
</xmlnode>
and all data-access is fine.
Now, this is an opposition to jta="false", isn't ? Is MyPU now JTA or not?
When I have to set the DataSource jta = "true" ?
