Philip St-Pierre - 11/Sep/07 09:05 AM I have the same error and I do use xfire 1.2.6. Here is my environment settings: Application server: Weblogic 8.1 sp6 JDK: jrockit-R27.1.0-jdk1.4.2_12 (J2SE 1.4.2) xfire 1.2.6 Spring 2.0.2 Hibernate 3.2.2ga I am trying to configure a service method to use a out/inout parameter. I am testing that with the book example. My server starts without any problems, but when I start my client test class, I get the following error: java.lang.NullPointerException: at org.codehaus.xfire.aegis.type.basic.HolderType.readObject(HolderType.java:54) at org.codehaus.xfire.aegis.AegisBindingProvider.readParameter(AegisBindingProvider.java:169) at org.codehaus.xfire.service.binding.AbstractBinding.read(AbstractBinding.java:206) at org.codehaus.xfire.service.binding.WrappedBinding.readMessage(WrappedBinding.java:51) at org.codehaus.xfire.soap.handler.SoapBodyHandler.invoke(SoapBodyHandler.java:42) at org.codehaus.xfire.handler.HandlerPipeline.invoke(HandlerPipeline.java:131) at org.codehaus.xfire.transport.DefaultEndpoint.onReceive(DefaultEndpoint.java:64) at org.codehaus.xfire.transport.AbstractChannel.receive(AbstractChannel.java:38) at org.codehaus.xfire.transport.http.XFireServletController.invoke(XFireServletController.java:304) at org.codehaus.xfire.transport.http.XFireServletController.doService(XFireServletController.java:129) at org.codehaus.xfire.spring.remoting.XFireServletControllerAdapter.handleRequest(XFireServletControllerAdapter.java:67) at org.codehaus.xfire.spring.remoting.XFireExporter.handleRequest(XFireExporter.java:48) at org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:45) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:820) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:755) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:396) at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:360) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at weblogic.servlet.internal.ServletStubImpl$ServletInvocationAction.run(ServletStubImpl.java:1077) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java:465) at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:28) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:27) at com.psws.patientportal.dmtool.audit.AuditFilter.doFilter(AuditFilter.java:31) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:27) at org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:173) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:77) at weblogic.servlet.internal.FilterChainImpl.doFilter(FilterChainImpl.java:27) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:7053) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.invokeServlet(WebAppServletContext.java:3902) Here are my classes and config files: public interface BookService { public Book[] getBooks();

Is it? Or did I miss any thing? The documentation doesn't say much on how to use out/inout parameters. Thank you Phil
