We're downloading jython modules from a server as the user requests them. Since the modules can live in different directories on the server we would like to keep the same directory structure on the client. So the plotTest.py file get downloaded to the pythonCache/a/b/scripts directory off of the current directory. I've tried the following code snippet to import the module but I can't quite get it to work: try: sys.path.index("pythonCache/a/b/scripts") except: sys.path.append("pythonCache/a/b/scripts") import pythonCache.a.b.plotTest pythonCache.a.b.plotTest.printHello() but I get ImportError: No module named plotTest what am I doing wrong here?

Thus, jython looks in the scripts directory for a pythonCache package containing an 'a' package containing a 'b' package containing a 'plotTest' package, and doesn't find it. Thus, I think you meant: cachedir = "pythonCache/a/b/scripts" if cachedir not in sys.path: sys.path.append( cachedir ) import plotTest plotTest.printHello() Note, however, that the requirements to be a Python package are different from the requirements to be a Java package: a Python package is a .py file or a directory containing an __init__.py file a Java package is any directory containing a Java class or containing a Java package kb |
