    cxf NullPointerException org.apache.cxf.wsdl11.WSDLServiceFactory

    Sterling Smith Newbie

      Hi All,

       

      I'm trying to get a soap client using the cxf / spring framework working; works great from within the Eclipse IDE.

       

      After building it for external use however, I get the following (debug dump follows):

       

      I'd appreciate any clues...could the WSDL be causing this?

          Hi,

           

          You need to pass the wsdl URL into the CmosWebServices construction.

          If you take a look at the CmosWebServices, you will find the default WSDL URL is using absolut path. When you wrap the classes into jar for external user to use, you will face the default WSDL URL can't find any WSDL issue.

            Yes, I did see that, and it's actually a follow up question.

             

            I am currently getting this problem running this on the same machine outside of Eclipse. It runs with a Run configuration but after packaging this with Maven (mvn assembly:assembly) the problem occurs running this on the same machine (so the file exists at run time). I suspect the problem you are indicating would be my NEXT problem after this worked running this outside of Eclipse and I moved it to the target machine.

             

            Any other ideas?

             

            (assuming I have another idea for my problem, here's my follow up question to the absolute path)

             

            BTW, what are best practices for making sure the Wsdl is available at runtime and/or idea for packaging and deployment (it's final resting place is a server outside of the Fuse ESB)? The generated wsdl path is a file path; wouldn't it be better to use a URL path where the service actually resides? If so, can I simply use a http path? I have to include the wsdl in my project as a file; perhaps I need a technique for referencing a target wsdl for wsdl2java using an external location?
