 Posted: Fri Oct 29, 2010 2:17 am Post subject: Calling Webservice with Output Parameters |
 |
|
I have been trying to call a web service I created that has 1 output parameter of type string and also has an integer return code. When I create the web service client and generate the stubs, I get a class for the returnresult of the web method. This class has methods to get the output parameter string result and the returncode value. The call to the web service is successful, but the returncode is null and the output parameter value returned by the class method is null. I can successfully call this same web service from VBA or a win32 form and it works just fine.
THe only type of web service methods I have been able to call inside my j2me application are ones that return a single value. So for instance, I could convert this web method to return a string instead of the returncode int and it works fine. The problem is I need the return code in addition to the output parameter string which is the xml result of the query.
What am I doing wrong? Is there a bug in the service stubs that are generated for web methods that return values via output parameters? Is there anything special I need to do to return the result from this call to the an instance of the result class that was generated?
Any insight would be greatly appreciated. I have been pulling out my hair for the last couple of days on this.
Thank you,
Steve |

Again, the AddUpdateEventValetUsers works fine or any webmethod I write that does not have any output parameters - just a return code. If I include an output parameter in the webmethod, I can never get a good result when calling from J2ME/Netbeans. If I call the web method from VBA or C# it works fine.
Thank you,
