Plugin Development Question

["Weber, Lance" <La...@McKesson.com>]

Hey guys, I finished a first cut at a basic SCM abstraction component (no,
really, I do!) and I'm trying to write a plugin to access it from Maven but
I'm stuck with a couple of questions.

I have an interface that exposes one or more methods with signatures like 

public String myMethod(String parm1, String parm2, boolean parm3, boolean
parm4) throws Exception

1) Can jelly instantiate a concrete class as an instance of an interface? 

2) Can jelly pass pararameters to a method call?

3) Can jelly return results from a method call?

Sorry if these are simple questions - I didn't see any good examples of the
above in the documentation or in the other plugins I looked at. Anyway,
thanks for any guidance.

The core new tag allows you to create new objects. As for being an 
'instance of an interface', I'm not sure what this means. See 
http://jakarta.apache.org/commons/sandbox/jelly/tags.html#core:new for 
more detail on new.

${object.method(param)}

Where both object and param are in the jelly context.

<j:set var="returnValue" value="${object.method(param)}" />
