Java SE (Java Platform, Standard Edition)

We are currently developing a Java application that allows other Java applications (jar files) to be downloaded from a remote compter/server and executed on a local PC using WebServices and the JNLP technology. This we have achieved and everything works OK.

However, we also need to download and run legacy applications (PC .exe's) and also X-applications all from our Java application. Essentially we want to replicate clicking a hyperlink in a Web Browser and having a program download an run, but to do this from our Java application

Any ideas on how this could be achieved.

Thanks in anticipation.
