override persistence.xml in geronimo plan

[phanibalaji]

Hi,
I saw a related JIRA created for this issue. Can you explain what can be overridden in geronimo plan and how? Is it for only <jta-datasource> and <non-jta-datasource>??
https://issues.apache.org/jira/browse/GERONIMO-3308

Thanks
Phani

I'd say everything can be overridden. See
jboss-seam-jee5-geronimo-plan.xml in Running JBoss Seam 2.0.0.GA on
Geronimo 2.1.1 (http://cwiki.apache.org/GMOxSAMPLES/running-jboss-seam-200ga-on-geronimo-211.html).

Thanks.I tested with a sample overriding persistence-unit in openejb-jar.xml. It worked well. Here are some more questions.

1. If a persistence-unit is declared both in openejb-jar.xml and persistence.xml, I guess, the declaration in openejb-jar.xml will override the one in persistence.xml entirely. That means, container will not perform union of what is declared in openejb-jar.xml and persistence.xml. am I right??

2. Does the point (1) above applies to only persistence-units declared in both persistence.xml and openejb-jar.xml?? I mean, if persistence.xml declares persistence-units which are not overridden in openejb-jar.xml, can the application access those persistence-units??

3. Can the persistence-units be overridden in geronimo-web.xml as well??

Thanks in advance

Comments based on memory, not the code..... check before relying on them...

I think some merging takes place.

yes

yes

hope this bears some resemblance to what the code does :-)
