Place a window application in a concrete place

[HenryChinaski]

I've made a Swing (java) Interface for an application, but now I need to open an external application and put it in some coords in the screen (i.e. open the iexplorer in 500,500).

Java brings some "Runtime" methods to run other programs in new threads, but they don't provide the funcionality to place the window.

There should be a solution using a DLL or something, but I'm completely lost and I don't know which method calls to use (and if works, it would be a good solution using the dll and jni).

So, anyone knows the methods or maybe a java solution?

Thanks in advance
