Question

I am building a Java application using JPA2 and Hibernate 4.0
I have a XML file describing the complex data types that the APIs take as input or give as output. Sample below. I want to use this XML to generate java classes (or a jar) that I can use in my APIs as parameters and return types. Also I want to put in this jar in the SpringMVC powered front end so that I may use these types to attach data to call my APIs with. I can change the format of the XML if needed.
What tool(s) can I use for this. I don’t write this XML to be mentioned in my APIs or any other code, the tool should let me create stubs and then forget about the XML.

  <documentation target="loginValidation" >
    Returns the result of login validation.
    Will return LoginValidationResults object if login correct, else a null object.
  </documentation>  
  <operation name="loginValidation">
    <input target="LoginValidationArgs" />
    <output target="LoginValidationResults" />
  </operation>

  <structure name="LoginValidationArgs">
    <member name="userName" target="String" />
    <member name="hashedPassword" target="String" />
    <member name="schoolID" target="PositiveInteger" />
  </structure>
  <required target="LoginValidationArgs$schoolID" />
  <required target="LoginValidationArgs$userName" />
  <required target="LoginValidationArgs$hashedPassword" />

  <structure name="LoginValidationResults">
    <member name="userID" target="PositiveInteger" />
    <member name="userType" target="String" />
    <member name="userDisplayName" target="String" />
    <member name="schoolID" target="Long" />
  </structure>
  <required target="LoginValidationResults$schoolID" />
  <required target="LoginValidationResults$userID" />
  <required target="LoginValidationResults$userType" />
  <required target="LoginValidationResults$userName" />

Look at my answer to a similar, but not duplicate, question

The answer is to use Eclipse’s M2T-JET. That’s what it was designed and built for.
