It means to do this properly and consistently for return types we need
to make Response generic. If you are not using Response ti return JAXB
representations then it is not an issue.
IMHO you are creating *a lot of work* for yourself when you can use
the work around of documenting the resource methods.
I am looking more at the code now and i think you may be able to plug
in your own support by providing an implementation of WadlGenerator
that extends from WadlGeneratorImpl that you overrides the createMethod.
See the ResourceConfig property PROPERTY_WADL_GENERATOR_CONFIG for how
to register a wadl generation implementation:
https://jersey.dev.java.net/nonav/apidocs/1.1.4/jersey/com/sun/jersey/api/core/ResourceConfig.html
#PROPERTY_WADL_GENERATOR_CONFIG
If you are using a web.xml you can declare an init-param:
<init-param>
<param-
name>com.sun.jersey.config.property.WadlGeneratorConfig</param-name>
<param-value>foo.MyWadlGeneratorConfig</param-value>
</init-param>
package foo;
class MyWadlGeneratorConfig extends WadlGeneratorConfig {
public List<WadlGeneratorDescription> configure() {
return generator(MyWadlGenerator.class).descriptions();
}
}
class MyWadlGenerator extends WadlGeneratorImpl {
@Override
public com.sun.research.ws.wadl.Method createMethod(
AbstractResource r, final AbstractResourceMethod m ) {
com.sun.research.ws.wadl.Method wm = super(r, wm);
// modify m based on input/ouput type of m
}
}
