Hello,

I'm facing strange behaviour. Sometimes, when I try to invoke a session bean, I run into the following exception:

com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract java.util.List myServlet.getData() throws myException' threw an unexpected exception: java.lang.IllegalStateException: No EJB receiver available for handling [appName:myAppNameEE,modulename:myModuleEJB,distinctname:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext at 3e23bd28

It usually happens when run my GWT application from Eclipse. The exception does not occur always. Sometimes it occurs fewer than others. Sometimes it occurs pretty every time I call a session bean and it's a pain. I read tutorial ( https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI?_sscc=t https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI?_sscc=t) and I am pretty sure to have the jboss-ejb-client.properties in the right place. I can't figure out what's going on. TIA.
