I used SoapUI to issue the following request: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:com="http://com.twocoast.tcsc.web.service"> | <soapenv:Header/> | <soapenv:Body> | <com:isConfigurationChangePending> | <serverName>QUATTRO</serverName> | </com:isConfigurationChangePending> | </soapenv:Body> | </soapenv:Envelope> and got the following response (no conversation Id): <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> | <env:Header/> | <env:Body> | <ns2:isConfigurationChangePendingResponse xmlns:ns2="http://com.twocoast.tcsc.web.service"> | <return>true</return> | </ns2:isConfigurationChangePendingResponse> | </env:Body> | </env:Envelope> If I annotate the isConfigurationChangePending with @Begin in the seam component (which is called by the SLSB annotated with @WebService) I get the following response: <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> | <env:Header/> | <env:Body> | <env:Fault> | <faultcode>env:Server</faultcode> | <faultstring>java.lang.IllegalStateException: Do not start long-running conversations in direct calls to EJBs</faultstring> | </env:Fault> | </env:Body> | </env:Envelope> I'm also seeing the following error show up in the log whenever a web request is processed (regardless of whether the method is annotated): 22:15:29,460 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator_4] TwoPhaseCoordinator.afterCompletion - returned failure for com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple@949f87 FYI- I'm using seam libraries built from CVS today.
