Hello,

I am generating Web Service based on the WSDL using myEclipse. As i need SPRING Capabilities for the generated Web Servivce, i am using "import WSDL" option under myEclipse when we right click on the project.

When I have input and output defined for operation in WSDL, then I am able to generate web service with SPRING capabilities. However if I go with just input in WSDL (no output) then it fails. Is there any such limitation ? if yes what is the workaround ?

Thanks & Regards,
Atul Samnerkar

Hello,

i have attached the WSDL file along with imported XSD file for your reference. Let me know if you need any additional information to debug this issue further.

Atul,

How does it fail? Is there an error message or a stack trace in the Console view? If you could post the detail on the error message, that would be helpful.

Here is the log...

Thanks Atul,

I see that the code is indeed requiring an output of some kind. Is there a way you can supply a void output in the WSDL? Otherwise, you would have to supply an output and just ignore it if it has no meaning.

Thanks for your quick response.

i am upgrading my existing system. The clients are already in place. I cannot modify the WSDL. what is the alternative to this if i have to generate SPRING Web Service wihtout output definition in the WSDL operation.

Regards,
Atul Samnerkar

Would it be possible for you to download the WSDL, make the necessary changes, generate the Spring Service and then touch up the code as necessary?


An alternate approach is to use the JAX-WS annotator. The service must be annotated with the @Service annotation, but then you can use the annotator to help lead you through the necessary annotations. There is a tutorial here: http://www.myeclipseide.com/documentation/quickstarts/ME4STutorialJaxwsAnnotator/jaxwsannotatorarticle.html
