Hi, I have a simple Axis2 POJO service which returns strings. Whenever I return a null I get the following exception on the server-side (however the server does send the client an axis fault). Any ideas?
Thanks Anthony java.lang.UnsupportedOperationException at org.apache.axis2.databinding.utils.reader.NullXMLStreamReader.getAttributeType(NullXMLStreamReader.java:147) at org.apache.axis2.util.StreamWrapper.getAttributeType(StreamWrapper.java:160) at org.apache.axiom.om.impl.builder.StAXBuilder.processAttributes(StAXBuilder.java:230) at org.apache.axiom.om.impl.builder.StAXOMBuilder.populateOMElement(StAXOMBuilder.java:433) at org.apache.axiom.om.impl.builder.StAXOMBuilder.createOMElement(StAXOMBuilder.java:462) at org.apache.axiom.om.impl.builder.StAXOMBuilder.createNextOMElement(StAXOMBuilder.java:319) at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:250) at org.apache.axiom.om.impl.llom.OMDocumentImpl.getOMDocumentElement(OMDocumentImpl.java:111) at org.apache.axiom.om.impl.builder.StAXOMBuilder.getDocumentElement(StAXOMBuilder.java:571) at org.apache.axiom.om.impl.builder.StAXOMBuilder.getDocumentElement(StAXOMBuilder.java:567) at org.apache.axis2.rpc.receivers.RPCUtil.processResponseAsDocLitWrapped(RPCUtil.java:369) at org.apache.axis2.rpc.receivers.RPCMessageReceiver.invokeBusinessLogic(RPCMessageReceiver.java:138) at org.apache.axis2.receivers.AbstractInOutMessageReceiver.invokeBusinessLogic(AbstractInOutMessageReceiver.java:40) at org.apache.axis2.receivers.AbstractMessageReceiver.receive(AbstractMessageReceiver.java:100) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:176) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:131) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) 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 com.tentelemed.webservices.server.IpFilter.doFilter(IpFilter.java:37) 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:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:619) 2011-10-26 15:35:58,708 -
