All, I'm running into an XML parsing problem while migrating a web service client based on AXIS and WSIF from WAS 4 to WAS 5. The error-message I get is: (the stacktrace is below) Provider null could not be instantiated: java.lang.NullPointerException: javax.xml.parsers.FactoryConfigurationError: Provider null could not be instantiated: java.lang.NullPointerException Does this problem sound familiar to anyone? All suggestions on how to fix this or on how to get more debug information are more then welcome. Thanks in advance, Cees van Wijk at javax.xml.parsers.DocumentBuilderFactory.newInstance(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.getDocument(Unknown Source) at com.ibm.wsdl.xml.WSDLReaderImpl.readWSDL(Unknown Source) at org.apache.wsif.util.WSIFUtils.readWSDL(WSIFUtils.java:401) at org.apache.wsif.base.WSIFServiceImpl.<init>(WSIFServiceImpl.java:186) at org.apache.wsif.base.WSIFServiceFactoryImpl.getService(WSIFServiceFactoryImpl.java:136) at dispatcher.WSDPServiceFactory.getServiceInstance(WSDPServiceFactory.java:165) at dispatcher.WSDPServiceFactory.getService(WSDPServiceFactory.java:132) at getcurrencyconversion.GetCurrencyConversionProxy.getService(GetCurrencyConversionProxy.java:59) at org.apache.jsp._test._jspService(_test.java:243) at com.ibm.ws.webcontainer.jsp.runtime.HttpJspBase.service(HttpJspBase.java:89) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.ibm.ws.webcontainer.jsp.servlet.JspServlet$JspServletWrapper.service(JspServlet.java:344) at com.ibm.ws.webcontainer.jsp.servlet.JspServlet.serviceJspFile(JspServlet.java:669) at com.ibm.ws.webcontainer.jsp.servlet.JspServlet.service(JspServlet.java:767) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.ibm.ws.webcontainer.servlet.StrictServletInstance.doService(StrictServletInstance.java:110) at com.ibm.ws.webcontainer.servlet.StrictLifecycleServlet._service(StrictLifecycleServlet.java:174) at com.ibm.ws.webcontainer.servlet.IdleServletState.service(StrictLifecycleServlet.java:313) at com.ibm.ws.webcontainer.servlet.StrictLifecycleServlet.service(StrictLifecycleServlet.java:116) at com.ibm.ws.webcontainer.servlet.ServletInstance.service(ServletInstance.java:283) at com.ibm.ws.webcontainer.servlet.ValidServletReferenceState.dispatch(ValidServletReferenceState.java:42) at com.ibm.ws.webcontainer.servlet.ServletInstanceReference.dispatch(ServletInstanceReference.java:40) at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.handleWebAppDispatch(WebAppRequestDispatcher.java:983) at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.dispatch(WebAppRequestDispatcher.java:564) at com.ibm.ws.webcontainer.webapp.WebAppRequestDispatcher.forward(WebAppRequestDispatcher.java:200) at com.ibm.ws.webcontainer.srt.WebAppInvoker.doForward(WebAppInvoker.java:119) at com.ibm.ws.webcontainer.srt.WebAppInvoker.handleInvocationHook(WebAppInvoker.java:276) at com.ibm.ws.webcontainer.cache.invocation.CachedInvocation.handleInvocation(CachedInvocation.java:71) at com.ibm.ws.webcontainer.srp.ServletRequestProcessor.dispatchByURI(ServletRequestProcessor.java:182) at com.ibm.ws.webcontainer.oselistener.OSEListenerDispatcher.service(OSEListener.java:334) at com.ibm.ws.webcontainer.http.HttpConnection.handleRequest(HttpConnection.java:56) at com.ibm.ws.http.HttpConnection.readAndHandleRequest(HttpConnection.java:618) at com.ibm.ws.http.HttpConnection.run(HttpConnection.java:439) at com.ibm.ws.util.ThreadPool$Worker.run(ThreadPool.java:672)
