This is a variant of a popular question around here. The problem is that you're assuming that the appserver works with WARs. Actually, a J2EE appserver (and really, Java in general) isn't expected to CARE where its classes and resources came from - if, in fact they were ever even in files to begin with - much less packages in an archive file. When you invoke a Java classloader (as the appserver is doing), you are actually simply requesting that it return a class/resource from WHEREVER it can find it. And while that CAN be a ".class" file or component of a WAR (or EAR or JAR), it might just as easily have been magically conjured up from a parallel universe. Even though YOU know where it came from, the class loading mechanism isn't allowed to make that assumption. So the short answer is "no". The ACTUAL answer is, "yes" - IF: 1, you embed it in a class; 2, you place it in a properties file; 3, you resort to some sort of gimmick like retrieving the file in the same way properties files are (by requesting them through the classloader); 4, you place the file in the content area of the WAR (where the JSP's are) and do an internal server request. All of the above solutions are only good if the file is read-only. For read/write access, you can only reliably locate the file by passing its location as an absoute path to a startup servlet or some similar mechansim that makes that value accessible to the web application.
