Recently, I got the External Method running fine. But after coming back from vacation for 5 days, I received the above error when running testing the External Method. The error was pointing to an import error. All the External Methods are stored in the Extensions directory. That particular method actually import a python file that resides in the same dir. I also added an entry in PYTHONPATH env variable so that it points to the Extensions directory. So what's wrong ??? Please cc a copy to this address hcsccs@prudential.com.my. Thanks, PauL ChunG
