Hi Thusitha,
i resolved above issue by adding method[1] but i need to know is there any
affect to platform due to that method. or is there any solutions other
then that[2]
[1]
public void connect(MessageContext messageContext) {
Thread currentThread = Thread.currentThread();
ClassLoader oldClassLoader = currentThread.getContextClassLoader();
try {
currentThread.setContextClassLoader(getClass().getClassLoader());
callEJBStateless(messageContext);
} catch (Exception e) {
handleException("Error in calling EJB Service from
EJB2Connector", e, messageContext);
} finally {
if (oldClassLoader != null) {
currentThread.setContextClassLoader(oldClassLoader);
}
}
}
