Not able to generate the stubs/java skeletons from the WSDL

Question

I have written a WSDL to generate the Stubs and skeleton but my skeletons are not getting generated in the eclipse. I am using Helios version of Eclipse.
Can any one tell what is the issue with WSDL?

I want to use Axis 2. I tried to generate the skeleton using wsdl2java also but it gives compilation issues in the generated classes. I am not able to attach the file here so I am pasting it here.

I had the same problem. I believe maven folder structure is causing it. I created a new project without maven and it worked. Added maven later. Also check source folders at "Java Build Path". If it is missing you will need to add it.

Answer 2

That's a problem with your install.

Download and verify axis2 and the axis2 eclipse plugins, make sure you've set up your AXIS2_HOME class paths.

Sometimes it stops working for me too, and then I have to go and reinstall everything. Don't bother making bug reports to Eclipse or Apache, they are always closed as "WORKSFORME".

Steps to produce code from your wsdl:

1. Create a dynamic web project.
2. Create your wsdl file.
3. Right-click on your wsdl file, select Web Services -> Generate Java Bean Skeleton
4. Click Finish

The Axis2 libraries, facets, and generated code will be added to your project automagically, and there will be no compilation problems.

I was facing the same trouble but now it has been solved. The problem is if you have a method that 'THROWS SOME KIND OF EXCEPTION', then it will cause the problem. Hence instead of throwing the error, try using try-catch block statement.
