[jbossws-issues] [JBoss JIRA] Updated: (JBWS-3101) NullPointerException if SOAPMessage Provider endpoint returns null to indicate a one way MEP

NullPointerException if SOAPMessage Provider endpoint returns null to indicate a one way MEP -------------------------------------------------------------------------------------------- Key: JBWS-3101 URL: https://jira.jboss.org/browse/JBWS-3101 Project: JBoss Web Services Issue Type: Bug Security Level: Public(Everyone can see) Components: jbossws-native Affects Versions: jbossws-native-3.3.1 Environment: JBossESB 4.8, JBossAS 5.1.0, JBossWS-Native 3.3.1 Reporter: Ray Cardillo Fix For: jbossws-native-3.4.1 JAX-WS Provider Endpoints are supposed to be able to return 'null' to indicate that it's a one way MEP and no response is needed. Web services ported from the Metro stack will fail on the Native stack if they use this feature because the Native stack seems to be expecting a non-null value to be returned at all times. The API clearly states that null can be returned from invoke() to indicate a one way MEP when no response is required: https://jax-ws.dev.java.net/nonav/jax-ws-20-pfd/api/javax/xml/ws/Provider... On the native stack, when trying to return null from a Provider<SOAPMessage> invoke() operation, a NullPointerException is thrown: 08:03:32,870 ERROR [RequestHandlerImpl] Error processing web service request org.jboss.ws.WSException: java.lang.NullPointerException at org.jboss.ws.WSException.rethrow(WSException.java:68) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.handleRequest(RequestHandlerImpl.java:362) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.doPost(RequestHandlerImpl.java:207) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.handleHttpRequest(RequestHandlerImpl.java:132) at org.jboss.wsf.common.servlet.AbstractEndpointServlet.service(AbstractEndpointServlet.java:87) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:235) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:190) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:92) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.process(SecurityContextEstablishmentValve.java:126) at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:70) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:330) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:829) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:598) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.NullPointerException at org.jboss.wsf.stack.jbws.RequestHandlerImpl.sendResponse(RequestHandlerImpl.java:435) at org.jboss.wsf.stack.jbws.RequestHandlerImpl.handleRequest(RequestHandlerImpl.java:358) ... 24 more
