Hi Indu,
Please send your questions to user@wso2.org, that way you can get the right
answers quickly and that's the way to go! :)
Anyway, I've searched through Internet and found few relevant links.
http://old.nabble.com/Issue-in-implementing-JPA-support-on-ESB-Smooks-Mediator-td33443274.html
http://wso2.org/mailarchive/architecture/2009-October/000669.html
And I think WSO2 human task component is an ideal example for you. Please
find the link to it below.
https://svn.wso2.org/repos/wso2/trunk/graphite/components/business-processes/humantask/org.wso2.carbon.humantask/
And I could see where persistenc.xml should go.
