If the file system permissions are set correctly, perhaps you have another program using your file and preventing other access to it.

Dear Jeff,

Thanks for your reply.
I assigned the location of my python files to "home" and jar file path to "jarFilePath". When I tried it, the error changed:

It says IOError: (2, 'File not found' --.../imageFileIo.py (Permission denied)) while I have no settings on the folder. Is it because java does not have access to folder? how can I solve it?

Regards,
Parisa

PySystemState is the sys module.  You need to initialize sys.path.  You can do it
by invoking python code in the interpreter, or by calling methods of PySystemState
from Java.  I do it like this:

      String initScript =
        "import sys\n" +
        "sys.path.insert(0,'"+home+"')\n" +
        "sys.path.append('"+jarFilePath+"')\n" +
        "sys.path.append('"+jarFilePath+"/Lib')\n";

      interp.exec(initScript);

I am trying to execute a python method from eclipse using jython. I managed to run it with following code:

PythonInterpreter.initialize(System.getProperties(), 
                         System.getProperties(), new String[0]); 
     
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.execfile("Mypython.py"); 
interpreter.eval("MyClassName().MyMethodName()")

My problem is when I import another python script which exists even in the same directory with Mypython.py. For example, when I add:

from food import Pizza

to Mypython.py, it starts to complain that cannot import. ImportError..

I found some questions about importing python libaries like os, but in my case this is not an issue.

I tried to make the folder as a package, add __init__.py etc but it failed.  I saw  some people use PySystemState, but I think it is for jython modules not user python scripts. if this is the solution please give me a simple example.

Could you please help me with that problem.
