> A customer is having a problem with concurrent access to a JCA endpoint that is deployed in WebSphere. The stacktrace is below.
> They are running a 2.0.x version of CXF with WebSphere 6.1.0.19, HP/UX version B.11.23, Java 1.5.0.13 .
> The problem is that the JCA connector uses a single MDB/EJB proxy for all threads which is causing the exception to be thrown. The solution is to create a pool of proxies which can be accessed so that the proxy is used by no more than 1 thread at a time.
