How to open a geoprocessing tool's dialog box w/ Java ArcObject?

[ChrisGreen]

A .Net solution is given, but I can't seem to find the GPToolCommandHelper object in the Java ArcObjects world.

As a work-around I am injecting VBA code to accomplish the task using IVbaApplication.insertCode, but I need to move from this.  Any help would be enormously appreciated.
