When attempting to run XA JDBC program on Websphere the following runtime error can occur:

13545 The XA Error is : -7
13546 The XA Error message is : Resource manager is unavailable.
13547 The Oracle Error code is : 17002
13548 The Oracle Error message is: Internal XA Error
13549 The cause is : null.

It turns out that from the stack trace/error a 17002 error means that the connection pool is handing out stale connections which have been closed. This is documented on IBM web site with various different ways of trouble shooting stale connection errors from WebSphere. See the link below.
