ODI error when trying ro reverse engineer-- Please help

Question

Hi all,
I am receiving the error below "ImportError: no module named java" when I am attempting reverse engineer from Essbase into the models tab in the ODI Designer.
I am using ODI version 10.1.3.5
I have all jar files related to Essbase in drivers folder. And all KMs related to Essbase in impexp folder. I have created CLASSPATH system variable with "D:\OraHome_ODI\oracledi\drivers". Should i need to add this path in PATH system variable?
What should i do to get this problem solved. Please help.
Thank you in advance for the help!!

MOS Note 424232.1 says
Such messages are probably due to either a stale Jython cache (.../scripting/cachedir folder) and / or insufficient access privileges attributed to the Unix user account which has launched either the ODI Agent or Designer GUI and is executing a Jython script and writing to the Jython cache (default value being .../lib/scripting/cachedir/packages folder).
Alternative workarounds:
1. Stop all ODI processes and remove the cachedir folder, the restart ODI and retest the process.
2. Use a different "python.cachedir" information, on which the User has write privileges. This Java property may be set into the Jython Registry and specifies the directory used internally by Jython for cached information about Java packages in ".jar" files. If the directory is relative, it is interpreted relative to the Jython root. For complete information, refer to Jython documentation, at:
http://www.jython.org/Project/userguide.html#the-jython-registry
3. Try running Jython once as "root" in order to create the Jython cache directories or take appropriate administrative actions (for example, chmod 777....) to allow the user account to access these files.
4. Please bear in mind that Unix is case sensitive... As such, do not forget to verify lower/upper case attributes of folder names.
If the ODI process is run by an Agent and the message is displayed:
1. Please check the ODI Agent in Topology Manager to determine on which host it is running then proceed to its installation folder and ...:
2. Verify that Jython is included with the Agent installation folders:
* In oracledi\bin - jython.sh
* In oracledi\lib\scripting - jython.jar, cachedir, and lib
* In oracle\lib\scripting\lib - numerous jython .py files
3. Also give Unix user account full permissions to every file and folder in the Agent installation and the java installation.
4. Restart the Agent.
5. Test the Agent in Topology Manager (ensure that the hostname is correct). If the test is successful, retest the Package/Scenario.
