Configuration:
Tomcat 6
Atomikos 3.7.0 installed on J2EE level (in Tomcat6/lib)

After hot deploying our WAR file, we consistently get this error:

java.lang.IllegalStateException: XATransactionResource already closed
    at com.atomikos.datasource.xa.XATransactionalResource.getResourceTransaction(XATransactionalResource.java:400)

Stopping and restarting Tomcat solves this problem.

Any idea what is wrong?

Only some guesses - you did not provide much information about your XAResource:

Where is your XAResource (i guess a datasource) configured?
I you do it via spring make sure you configured init-method and destroy-method on the DataSource Beans to close + start the Resource on spring context startup/shutdown.

If done via JNDI you are stuck with Tomcat6 - tomcat7 does provide some hooks to call a destroy on a jndi resource, tomcat6 does not have this ability afaik.
