I'am unable to deploy a very simple application via eclipse indigo/juno 4.2
I get the following exception:
Runtime exception occurred in publish task 'SplitsrcTargetPreparation'
See attached screenshot
Note: I'm working with weblogic 10.3.6 dev.
It seems that weblogic is under edit and lock mode and can you open weblogic console and try to change it correctly.
Still you get same problem then try to remove the application reference with in server upload folder.
This will solve your problem.
