EDI copyTemplate hanging

After following instructions of downloading the .template file into directory (as per Installing Existing schema and template Ch 6 EDICoreUserGuide.pdf), the call to copyTemplate hangs. Any help will be appreciated.

The EDI packages and their associated packages are fairly memory intensive, especially within the webMethods Developer- You may want to bump up your JVM Min & Max settings within the integrator.bat file-

I’m facing on the same problem.
do you know the suggested value to set the Memory?
