WEB-INF Folder JRun Install

I am trying to add a jar file which is the compresssor in tiny mce. I was able to add it without any problem on the 7dev server. The path to it was C:\ColdFusion8\wwwroot\WEB-INF\lib

However, I am not sure where to add it on the JRun ColdFusion setup.
Here is what the instructions said at tiny MCE.
Copy the tinymce_gzipcompressor.jar to the Web-inf/lib or the <cf installation path>/lib.
