java - Using getClass().getResource(resourceLocation) in Play Framework -

i'm having play application , want load files jars /lib folder. got code supposed use, code includes following line:

classloader.getsystemresourceasstream("model/model.jar")

play.application().resourceasstream("model/model.jar") 

this did work me. however, depend on library , library using following line of code:

url crfexecurl = this.getclass().getresource(loc); 

the resource accessible @ string stored in loc, relative .jar class above line of code located. can't change code use again play function though. there way, can setup play framework, allowing resource extraction?
