but I have this error, where I wrong?

It seems that I cannot load the file alextest.py but the file exists!

Thanks!!

If twisted's sob.py is one of the last modules in the traceback then the problem is almost certainly in the .tac file. In this case, the error is a syntax error on line 1 of the .tac file. I suspect that you have a DOS vs UNIX line ending problem. Have you copied the file from DOS to UNIX (or vice versa) without fixing the line endings? It looks like you're on a Linux box so "file runapp.tac" will probably report that you have CRLF line endings. If so, use flip (or similar tool) to change the line endings and try it all again. Hope this helps. Cheers, Matt -- Matt Goodall <matt@pollenation.net>
