Java Connector parameter

Hi, Im using FCKeditor with the java integration pack. I need to be able to pass addtional parameters (request.getParameter) to the connector servlet when a user uploads a file but have no idea how to accomplish this. The parameter name will be consistent throughout although the value will be generated on the jsp page where the editor is shown (using the jsp tags provided with the inetegration pack).

Im looking for the place where the connector url is contructed inorder to pass a new parameter (i.e ?id=21) to the end of the url. i was hoping a specify an attribute in the jsp tags to hold the name and value and use that somewhere to construct the parameter.

Any Ideas?

Cheers, Ry
