How does a native calling application get a return value from JNLP?

Question

I am launching a JNLP java application from a native client app (i.e. not a browser). When the JNLP finishes it's task, I need it to return a string to the calling app? How can I do this? Is it possible to return a value to a calling app - or do I need to have the calling app listen on a port and have the JNLP app write the value to that port through sockets?

Answering my own question!

I write to stdout from the child process (the JNLP)

• The parent launches the child process

  Process::Start
  

• Read stdout from Parent

  string ret = process.StandardOutput.ReadToEnd();
  

• Process::WaitForExit();
  

Anyone sees any problem in this?
