Re: [Jython-users] ImportError: no module named java

Hi all,

Thanks Robert Bill & Jim Adrig for the tips....

I've been trying, in every manner possible! Here's my code --

  rootPath = servletContext.getRealPath("/");
  if (!rootPath.endsWith(File.separator)) rootPath += File.separator;

  Properties p = getInitParametersAsProperties();
  p.put(
    "python.cachedir",
    servletContext.getAttribute("javax.servlet.context.tempdir").toString());
  PythonInterpreter.initialize(System.getProperties(), p, new String[0]);

  PySystemState pySys = Py.getSystemState();
  pySys.add_classdir(rootPath + "WEB-INF" + File.separator + "classes");
  pySys.add_extdir(rootPath + "WEB-INF" + File.separator + "lib");
  pySys.path.append(new PyString(servletContext.getAttribute("python.home") +
    File.separator + "Lib"));
  pySys.path.append(new PyString(rootPath + "WEB-INF" + File.separator +
   "py"));

  pythonInterpreter = new PythonInterpreter(null, pySys);

I think, based on looking at PyServlet.java, that this should get all my 
bases covered. However, I still get --

  import os
  dir(os)

  Traceback (innermost last): File "", line 10, in ? ImportError: no
    module named javaos 

  import os
  print os.listdir('/home/ihab')    

  Traceback (innermost last): File "", line 2, in ? AttributeError: class
    'org.python.modules.os' has no attribute 'listdir' 

This is all very confusing. Any help appreciated from anyone. Peace,

Ihab
