XCC invoke calls pass parameters as external variables not as form parameters.
App servers called with HTTP are passed form parameters available as 
xdmp:get-request-field-names
They are completely different protocols and calling methods.

When XCC calls a module it's like calling xdmp:invoke()
http://docs.marklogic.com/xdmp:invoke

You get the external variables like this:

declare variable $searchparam external;

There are some tricks you can do to use the same statement to get both form 
parameters AND external params but I dont recommend it until you get the basics 
to work.

Subject: [MarkLogic Dev General] XCC query parameterers

Hi All,

I am having an issue when invoking a search xquery(with search:search api) 
through XCC in Java.
I am invoking the query with parameters as follows in Java.

        Request request = session.newModuleInvoke ("search.xqy");
        request.setNewStringVariable("searchparam", "payment");
        request.setNewStringVariable("start","1" );
        request.setNewStringVariable("pagesize", "10");

But in my xquery when checking for parameters in u
no parameters are coming. And as no search parameter is parsed the search query 
is just returning all the documents in the database.

Where as the same query when invoking through HTTP port is working fine it is 
identifying the parameters and performing a valid search.

Please advise what changes need to be done for XCC.

Thanks,
Rushabh Mehta
