Atomikos Forum

I am trying to configure Atomikos for XA transactions and XS datasource. My Spring configuration file is pasted below the exception. I was able to run with this configuration for 1 unit test.

If I run more then 1 unit test from Maven, or if I try to run our web app with this configuration in Jetty, I get "Another resource already exists" exception, even though there is only 1 declaration of the datasource. I think Atomikos is not handling application context refreshes and somehow it ends up trying to register the name of the datasource twice.

Is there a known issue or is there something in my configuration?

We have a known issue with spring test contexts - if they are dirty then refresh does not work (or something similar if I remember correctly).

We only detect init or close events in our beans - not sure how we can avoid this. A workaround is to avoid context refreshes altogether (is that possible for you?).

HTH

Thank you for your reply. We may be OK if it was just unit tests not working, but I get the same problem in the web app when Jetty starts it up.

I think it's not just refresh issue. There are several modules deployed on the same JVM (we are using Gigaspaces and Jetty) and I think each is loading the same Spring context. So within a JVM there are several data sources but they must be loaded with a different classloader.

Is there a way to tell AtomikosDataSourceBean that "uniqueResourceName" doesn't have to be unique? We don't use that property at all.

Can Atomikos work correctly in such scenario (multiple web apps/Spring contexts on the same JVM)?

Hi,

The uniqueResourceName is needed for recovery purposes of the XA module so that can't be left out.

I think you must be seeing some class loading issue here... Did you make sure that all the atomikos jars are in the Jetty server classpath?
