Question

I'm trying to call a web service with a Java client. The WSDL looks like this: http://pastebin.com/m13124ba

My client:

public class Client{
    public static void main(java.lang.String args[]){
        try{
            CompileAndExecuteServiceInterfaceStub stub =
                new CompileAndExecuteServiceInterfaceStub
                ("http://192.168.1.3:8080/axis2/services/CompileAndExecuteServiceInterface");

            Compile comp = new Compile();
            comp.setArgs0("Test");
            comp.setArgs1("public class Test { public static void main(String[] args) { System.out.println(\"Hello\");}}");
            String[] classpath = {};
            comp.setArgs2(classpath);
            stub.compile(comp);

        } catch(Exception e){
            e.printStackTrace();


        }
    }

}

When I run the client now the following error occurs:

org.apache.axis2.AxisFault: unknown


at org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:517)
at org.apache.axis2.description.OutInAxisOperationClient.handleResponse(OutInAxisOperation.java:371)

at de.dax.compileandexecuteclient.Client.main(Client.java:17)</blockquote>

I tried out the business logic of the server on my local machine and there it works. The service creates files and folders. Are web services allowed to do that? I also wrote a simple "Hello World" web service and deployed it to the server. This worked fine.

Was it helpful?

Solution 3

The problem was that there was an NullPointerException in my service.

OTHER TIPS

When you get one of these "unknown" AxisFaults, definitely check the server log! The client-side stack trace most likely will not be detailed enough for you to track down the error.

I believe dax is indicating above that he found the NullPointerException in the more-detailed server side stack trace. It would look something like:

org.apache.axis2.AxisFault
    at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430)

    [....]

Caused by: java.lang.NullPointerException

    [....]

From the provided logs, I cannot determine what's wrong. Try to set the log-level of Axis2 to "debug" (see the two log-configurations in the root directory of your Axis2 installation) and check the details for the exact cause. Axis2 tends to be a bit sparse in propagating the errors coming from webservices.
