I am working on deploying a J2ee application that I have previously been deploying in JBOSS into Weblogic 10.3.1.0. I am running into an issue with external properties file
In weblogic jars will be loaded from the lib and the non jar files will be loaded from the domain folder
The most flexible way is to use weblogic deployment plans and Generic File Loading overrides
External properties file with Weblogic
