My jboss 2.4.6 instance is running for a month or something. Since yesterday I began to face the following exceptions:
java.lang.NullPointerException
at org.jboss.pool.jdbc.xa.XAPoolDataSource.getConnection(XAPoolDataSource.java:216)
at com.tw.eazybuild.ejb.EjbUtil.getConnection(EjbUtil.java:108)

It's here:
[...]
212: String user = factory.getUser();
213: String password = factory.getPassword();
214: String[] params = {user, password};
215: XAConnection xaConn = (XAConnection) pool.getObject(params);
216: return xaConn.getConnection();
^^^^
[...]
Why can it happen? To temporary solve the problem I invoke stop/start on the XAPoolDataSource MBean. It helps for a day or so. Before I never faced the problem, and my jboss configuration has not changed since I started it month ago.
Best wishes,
