Re: problem with ServiceManagerClient and another problem

I modified the source as you tell and know I receive this exception:

Oops.  I see you marked line 19.

This means ret, the return value, was null.  That almost certainly indicates
that the server returned a Fault.  Try changing your code to the more
standard:

      try {
         Response resp = call.invoke(url, "");
         if (resp.generatedFault()) {
             Fault fault = resp.getFault();
             System.err.println("Generated fault: " + fault);
         } else {
             Parameter ret = resp.getReturnValue();
             Object value = ret.getValue();   *\this is line 19
             System.out.println("Result is " + value);
         }
      }
      catch (SOAPException e) {
         System.err.println("Caught SOAPException (" +
                         e.getFaultCode() + "): " +
                         e.getMessage());
      }

I am suspicious of e-mail wrapping lines in messages.  Can you tell me which
is line 19 in your source?
