Initial database creation in JBoss Portal

[portaluser123]

Hi,

I am new to JBoss portal.
I have a query regarding database creation.
After starting JBoss portal, I deleted the Weather portlet using portal console .But when I restarted the server again, I am able to see the weather portlet. So, can anyone please let me know how the initial database will be created in portal at server startup,which files or properties it uses to create this weather portlet again?

Thanks
