The full exception is given below as well > as the tst.css and tst.js files. The behavior is valid, but is easy to fix. Here, the JSP page uses a writer. Since the static page server is also a servlet, it can't use an output stream to output the data (you'll get that ISE if you call getOutputStream()). It will attempt to use the writer in that particular case, but only if the file being included is a text file (it's the case here, but there's no MIME type for .js). The test used is that the MIME type of the included file has to be starting with "text". Adding the following mapping in your web.xml should make it work: js text/plain Remy
