wsadmin AdminApp.install of a 23MB EAR is hanging

Question

I'm able to log into my local WAS 8 admin console and deploy a 23MB EAR with all of the defaults with no problems. However, when I attempt to do the install using wsadmin and this Jython script...

AdminApp.install('C:\Development\MyApp\MyApp.ear')
AdminConfig.save()

... wsadmin just hangs. I've been running this script right now for well over 10 minutes with my CPU at 70% on the java.exe process responsible for the deploy.

I would like to run my EAR deploys/undeploys using wsadmin if at all possible to bypass the need to log into the admin console.

Are there settings specific to wsadmin that I could tweak to make this deploy successful?

EDIT I
I tweaked my wsadmin call to launch like this (it gets called from a DOS command line...)

C:\Development\batch>call "C:\Development\WebSphere\WAS8.0\bin\wsadmin" -lang jython -conntype none -javaoption -Xms256m -Xmx1024m -f MyApp\MyAppDeploy.py

and now I'm getting java.lang.OutOfMemoryError...

Answer 1

The following solved it for me. This launched from the DOS command line on my PC.

call "C:\Development\WebSphere\WAS8.0\bin\wsadmin" -lang jython -javaoption -Xmx1024m -f %1
