why wsdl2java uses input element name to name the corresponding method?

["Liu, Hua (Maria)" <Hu...@xerox.com>]

Hi,

 

I wrote a simple Math service which has only one method "add" taking two
integers and return the sum. In Math.wsdl, I defined the operation
"add", and it receives an input message which contains an element named
"addReq". I used "wsdl2java.bat -osgi mini -wsdl Math.wsdl" to generate
the skeleton code and the method is named as "addReq". 

 

Then I dig into the source code and found out that
ResourceInspector.java uses the input element name ("addReq") to name
the method in the java code:

private JavaMethod createJavaMethod(Element wsdl, Operation op)

    {

        JavaMethod method = new JavaMethod();

        method.setName(getInputName(op));

        .........

    }

This confuses me a lot. Would someone please help me?

 

Thanks,

Hua
