Axis2 and WSF: Mapping qname not fond for the package

Hello, I've got some trouble when I use some JPA detached entity in my Web services. At the runtime, the returned error is: org.apache.axis2.rpc.receivers.RPCMessageReceiver - java.lang.RuntimeException: org.apache.axis2.AxisFault: Mapping qname not fond for the package: XXX.entity.jpa org.apache.axiom.om.OMException: java.lang.RuntimeException: org.apache.axis2.AxisFault: Mapping qname not fond for the package: XXX.entity.jpa     at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:247)     at org.apache.axiom.om.impl.llom.OMNodeImpl.build(OMNodeImpl.java:319)     at org.apache.axiom.om.impl.llom.OMElementImpl.build(OMElementImpl.java:650)     at org.apache.axiom.om.impl.llom.OMElementImpl.detach(OMElementImpl.java:619)     at org.apache.axiom.om.impl.llom.OMNodeImpl.setParent(OMNodeImpl.java:118)     at org.apache.axiom.om.impl.llom.OMElementImpl.addChild(OMElementImpl.java:269)     at org.apache.axiom.om.impl.llom.OMElementImpl.addChild(OMElementImpl.java:198)     at org.apache.axis2.rpc.receivers.RPCUtil.processResponseAsDocLitWrapped(RPCUtil.java:381)     at org.apache.axis2.rpc.receivers.RPCMessageReceiver.invokeBusinessLogic(RPCMessageReceiver.java:134)     at org.apache.axis2.receivers.AbstractInOutMessageReceiver.invokeBusinessLogic(AbstractInOutMessageReceiver.java:40)     at org.apache.axis2.receivers.AbstractMessageReceiver.receive(AbstractMessageReceiver.java:96)     at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:148)     at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:275)     at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:121)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:710)     at javax.servlet.http.HttpServlet.service(HttpServlet.java:803)     at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)     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:175)     at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128)     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:286)     at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844)     at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583)     at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447)     at java.lang.Thread.run(Thread.java:619)  Caused by: java.lang.RuntimeException: org.apache.axis2.AxisFault: Mapping qname not fond for the package: com.thomson.smv.contentrecommendation.entity.jpa     at org.apache.axis2.databinding.utils.BeanUtil.getPullParser(BeanUtil.java:264)     at org.apache.axis2.databinding.utils.reader.ADBXMLStreamReaderImpl.processProperties(ADBXMLStreamReaderImpl.java:988)     at org.apache.axis2.databinding.utils.reader.ADBXMLStreamReaderImpl.next(ADBXMLStreamReaderImpl.java:835)     at org.apache.axis2.util.StreamWrapper.next(StreamWrapper.java:71)     at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:159)     ... 27 more Caused by: org.apache.axis2.AxisFault: Mapping qname not fond for the package: com.thomson.smv.contentrecommendation.entity.jpa     at org.apache.axis2.databinding.utils.BeanUtil.getPullParser(BeanUtil.java:102)     ... 31 more   This error has occured during the following web service execution: package XXX.ws.contentservice; import java.util.List; import XXX.entity.Content; import XXX.service.ContentService; public class ContentServiceWS_1dot1 {     private ContentService contentService;     public void setContentService(ContentService contentService) {         this.contentService = contentService;     }     public Content[] getContentList() {         List<Content> contentList = contentService.getContentList();         return contentList.toArray(new Content[contentList.size()]);     }     public Content[] getContentListPagging(int first, int count, String order,             boolean isAscending) {         List<Content> contentList = contentService.getContentList(first, count,                 order, isAscending);         return contentList.toArray(new Content[contentList.size()]);     }     public Content getContent(String id) {         return contentService.getContent(id);     }     public long getContentNumber() {         return contentService.getContentNumber();     }     public boolean isTitleExist(String title) {         return contentService.isTitleExist(title);     } }   The ContentService object is a service interface. A ContentService's implementation is injected by Spring. This service implementation calls a Spring injected DAO. The Content object is also a server interface. The implementation of the Content interface is made by the DAO implementation. The Content interface implementation is XXX.entity.jpa.ContentImplJPA, that is the only class of the XXX.entity.jpa package, that is the package that causes the qname mapping problem. But: My web service don't call directly the XXX.entity.jpa.ContentImplJPA, but by using Spring injection, this is the implementation that is used for implementing the Content interface. My Content interface implementation is in my classpath (mandatory for injection) Then I'm suspecting a problem of class loading during qname resolution. Do you have an idea about that?      For you information, I'm using the following configuration: WSF/Spring 1.0 Spring 2.5.5 Axis 2.   Here is the list of used jars (with version when it's possible): activation-1.1.jar addressing-SNAPSHOT.mar annogen-0.1.0.jar aopalliance.jar asm.jar asm-attrs.jar aspectjrt.jar aspectjweaver.jar axiom-api-1.2.6.jar axiom-dom-1.2.6.jar axiom-impl-1.2.6.jar axis2-adb-1.35.jar axis2-kernel-1.35.jar backport-util-concurrent-2.2.jar c3p0-0.9.1.2.jar catalina-5.5.15.jar cglib-2.1.3.jar commonj.sdo_2.1.0.jar commons-codec-1.2.jar commons-collections-3.2.jar commons-digester-1.2.jar commons-fileupload-1.1.1.jar commons-httpclient-3.0.1.jar commons-io-1.2.jar commons-lang-2.1.jar commons-logging-1.1.jar commons-modeler-1.1.jar commons-pool-1.3.jar dom4j-1.6.1.jar eclipselink.jar geronimo-activation_1.1_spec-1.0-M1.jar geronimo-jms_1.1_spec-1.1.jar geronimo-jpa_3.0_spec-1.0.jar geronimo-jta_1.1_spec-1.1.jar geronimo-stax-api_1.0_spec-1.0.jar httpcore-4.0-alpha6.jar httpcore-nio-4.0-alpha6.jar httpcore-niossl-4.0-alpha6.jar jaxen-1.1-beta-7.jar jaxen-1.1-beta-9.jar jta.jar junit-3.8.1.jar log4j-1.2.15.jar mail-1.4.jar mx4j-jmx-1.1.jar mysql-connector-java-5.0.8-bin.jar neethi-2.0.2.jar openjpa-1.1.0.jar persistence.jar serp-1.13.1.jar slf4j-api-1.5.0.jar slf4j-log4j12-1.5.0.jar spring-aop.jar spring-beans.jar spring-context.jar spring-context-support.jar spring-core.jar spring-jdbc.jar spring-orm.jar spring-sources.jar spring-tomcat-weaver.jar spring-tx.jar spring-web.jar stax-api-1.0.1.jar woden-1.0-incubating-M7b.jar woden-api-0.95.jar wsdl4j-1.6.1.jar wsf-spring-1.0.jar wstx-asl-3.2.1.jar xalan-2.7.0.jar xercesImpl-2.8.1.jar xml-apis-1.3.03.jar xmlParserAPIs-2.6.0.jar XmlSchema-1.3.2.jar
