Hi,
I am trying to use a web service  to receive message and inoke  to  
another web services. But I kept getting the below errors when 
invoking the web services,

WSDLException: faultCode=CONFIGURATION_ERROR: Problem instantiating

the problem seems to be with WSDL4J - make sure that you do not have 
multiple copies of WSDL4J jar files in tomcat/** and in your 
webapps/WEB-INF/lib/* - also try different versions of WSDL4J.

Here is my code for invoking the webservice ,
...
 
WSIFPluggableProviders.overrideDefaultProvider("http://schemas.xmlsoap.org/wsdl/soap/";, 
new WSIFDynamicProvider_ApacheAxis());
   System.out.println("Reading WSDL document from '" + wsdlLocation + 
"'");
   try
   {
   //org.apache.wsif.wsdl.WSIFWSDLFactoryImpl ();
   WSDLFactory factory = 
WSDLFactory.newInstance("org.apache.wsif.wsdl.WSIFWSDLFactoryImpl");
    Definition def = factory.newDefinition(); // test line
   Definition def1 = org.apache.wsif.util.WSIFUtils.readWSDL(null, 
wsdlLocation); //test

   }
   catch(WSDLException e)
   {
     e.printStackTrace();
   }
   System.out.println("Preparing WSIF dynamic invocation");
...
However, with the same wsdl4j.jar and wsif. jar, the above code works 
fine from a non-servlet client, but once put into servlet( in my case, 
web service API), the error happened.

I use the Jbuilder 2005, Tomcat 5.0.28, wsif.jar ( from 2.0 release), 
wsdl4j.jar

Have anyone experienced this issue before, how to solve this? Thanks.
Bob
