    CXF SE causing NPE

      Hi,

      I have a serious problem with CXF SE (2.0.6) component which I use for implementing web service endpoint.

       

      My web service executes Drools engine (not servicemix-drools) and terminates with exception during loading facts to working memory. It terminates only when number of facts exceeds ca. 450. I tested the rules outside ServiceMix (and CXF) and there was no problem.

       

      This is the exception I found in the log of Servicemix:

       

      2008-08-13 10:48:14 org.apache.cxf.phase.PhaseInterceptorChain doIntercept

      INFO: Application has thrown exception, unwinding now: java.lang.NullPointerExce

      ption: null

       

      I suppose the CXF component can't allocate enough memory?

       

      What can I do? Thanks in advance.

       

      Regards,

      Pawel Kaczor

          Can you check to see if you've specified the operation in the ME when invoking on the CXF SE?

            I'm not sure what you mean.

             

            This is my web service interface:

             

            @WebService(name="DataIntegrityCheck", targetNamespace = "http://company.com/reporttool/dataintegrity")

            @SOAPBinding(style=Style.DOCUMENT,parameterStyle=ParameterStyle.BARE)       

            public interface DataIntegrityCheckService {

            @Oneway
            public void startService(String ruleName);

            }

             

            CXF SE endpoint definition:

             

            <cxfse:endpoint>

            <cxfse:pojo>bq. <bean id="checkEngine"  class="com.consileon.ct.dataintegrity.DataIntegrityCheckServiceImpl">bq. <property name="entityManagerFactory" ref="entityManagerFactory"/>
            <property name="context" ref="context"/>

                      </bean>

             

                 </cxfse:pojo>

             

            </cxfse:endpoint>

             

            and CXF BC definition:

            <cxfbc:consumer wsdl="classpath:DataIntegrityCheckService.wsdl" endpoint="DataIntegrityCheck" service="integrity:DataIntegrityCheckService" interfaceName="integrity:DataIntegrityCheckPort" targetService="integrity:DataIntegrityCheckService"

            />

              I didn't realise the CXF BC was invoking directly on the SE, I thought there was another component in between that may not have been setting the operation on the Message Exchange that was passed to the SE.

               

              Can you get a full stack and print it here?

              I presume there is a good reason to deploy this in FUSE ESB rather than just using FUSE SF directly?

                I found the problem, finally.

                My application is throwing NPE but the exception was not reported properly by. I could see only :

                 

                2008-08-22 15:07:33 org.apache.cxf.phase.PhaseInterceptorChain doIntercept

                INFO: Application has thrown exception, unwinding now: java.lang.NullPointerException: null.

                I migrated from CXF 2.0.6 to 2.0.8 (most recent FUSE ESB)

                and now I can see what was the cause of the error.

                 

                Thanks anyway.

                  What version of Servicemix you are using?

                  Can you try latest one like 3.2.2 or Latest Snapshot?

                  It may be related to the issue https://issues.apache.org/activemq/browse/SM-1225

                    I used fuse-esb-3.3.1.3-windows and now fuse-esb-3.3.1.5-windows
