> Hi All -
>
> I'm new to AXIS and Web Services. I have read and followed the AXIS docs
> and simple examples, but have a problem with my own multi-threaded AXIS
> Test Client I created. I used the wsdl2java utility to generated the Java
> classes from a WSDL file that was given to me.
>
> Basically I have a Test class and an inner class (Thread) that does the
> actual work of sending requests and receiving responses. Each Thread
> (Client) works in two modes [1] Reuses it's Web Object reference [2]
> Creates a new web object reference each time. I do this to test the cost
> of reusing the web object reference verses creating it each time.
>
> This is a snippet of code from my inner class, the constructor creates the
> reusable mNvsClient web object reference, if I need to create it each time
> I call createWebServiceReference() directly.
>
> /**
> * Constructor
> * @param pThreadID Thread ID to use when reporting back the
> results.
> */
> public Worker(int pThreadID) {
>
> mWorkerThreadID = pThreadID;
>
> // Create the reusable Web Service Object
> if (mReuseWebServiceObject) {
> mNvsClient = createWebServiceReference();
> }

> /**
> * Creates a new Web Service Object

> private synchronized NVSGUSStub createWebServiceReference() {
> NVSGUSStub client = null;
> try {
> NVSGUS_Service nvsService = new NVSGUS_ServiceLocator();
> client = (NVSGUSStub) nvsService.getNVSGUS();
> }
> catch (ServiceException e) {
> e.printStackTrace();
> }
> return client;
> }

> However, when I run my client with more than one thread (client) I get the
> following error repeated for different classes:
