Where does one deposit a custom javascript library for use with Oracle Reports 11g/12c in Weblogic?

I am trying to implement something with JavaScript on the Parameter From in an Oracle Report. I am hitting an upper limit with respect to the number of lines of code I can put in the Before Form Value property. When you hit that limit, you are no longer able to save the report.

I'd like to save my changes to a separate *.js file and reference that. Is there a spot where I can put that on the filesystem (running Weblogic on Windows) or do I have to do something like create a war file and "deploy" it?

Any guidance appreciated.
