datasource already registered error in deploying JPA war file to JBoss

[Dave Wimberly]

Has anyone encountered this error in JBoss AS 7.1.
I've got a simple application that uses JPA - referencing a data source that is already in standalone server. I added the data source via the admin console.

This is stack trace:

I've not found much on this sort of error. Everything is running on Windows 7 - 64-bit.

Thanks,

That doesn't look like the entire exception stacktrace. Please post the entire exception stacktrace and your datasource configurations.

While posting, wrap the logs and xml content in a code block by using the Code button in the message editor window. Use the Preview button to make sure the post is correctly formatted.

Hi, this is the subsection for the datasources in standalone\configuration\standalone.xml... Added the Oracle data source via the console -- except for the "check-valid-connection-sql".

Service jboss.naming.context.java.jboss.datasources.Core2DS is already registered

This happened to me while playing with JBoss EAP 6/7.1

Not only are you declaring it in some xml file buried in JBoss, but also within your war.
I don't know exactly where off hand, but look for Core2DS in your instalation.

Thanks William,
I found the duplicate DataSource XML file!
I'm using these new JBoss Maven project templates in Eclipse and must have done something wrong to make it generate the additional data source to deploy.
