After invoking an operation by "try it" using WSO2 Application Server, admin area. I get this error. I have created a wsdl file using eclipse and generate server side code using Axis2 code generator, then I archive it using Axis2 archiver and deployed it in my Application server. Can I attribute this problem to difference of Axis2 versions on WSo2 and my eclipse plugin?
My problem was attributed to jar files and their version! I used the axis2 1.4.0 for compiling and code generation while the WSO2 application server used the axis2 1.6.0.1 version of the library. So this was making the error! Just changed the Axi2 1.4.0 to axis2 1.6.0.1 and everything went well.
