Re: [Jython-dev] ImportError: No module named site

Thank you, Alex! Setting python.home to the user's home directory, in combination with the recipe you provided *worked* for me too, so I am now able to webstart my application on jython2.7b3! Do you have an account on stackoverflow? Would you be interesting in providing your answer there? In the process of testing, I opened the Windows Task Manager and discovered that my client machine was choking on a large number of javaws.exe and jp2launcher.exe processes! I do not know where these came from, because I was bouncing back and forth between jython2.7b3 and jython2.7b4. But, I do have at least one confirmed instance of jython2.7b4 leaving behind a jp2launcher.exe with a 500M footprint. On jython2.7b4, my application *does* webstart, but it hangs almost immediately after webstarting, at the very place where I attempt to initialize the JavaFX runtime. (I was at one time breaking the Python rule against starting a thread and waiting for it in the midst of a module import, but that is fixed now.) The same application starts without issue when I run it locally, without webstart.
