Hi, I've seen that this error has been in the discussion here a few times, but finally has never been answered. It occures *sometimes*, when a JSP uses a java class. To make things clear: I only use the standard tools: JBuilder4 and once in a while EditPlus (an editor that is definitely not screwing up the files). So the error message is: Error: 500 Location: /myapp/someJSP.jsp Internal Servlet Error: org.apache.jasper.JasperException: Unable to compile class for JSPC:\test_cat2\webapps\myapp\WEB-INF\CLASSES\com\mycomp\Constants.java:1: The source file encoding may be different with this platform encoding. Please use -encoding option to adjust file encoding, or apply native2ascii utility to make source file ASCII encoding. I use Tomcat 3.2.2, but I've seen this "error" has also shown up in Tomcat 3.1. The file the compiler complains about comes out of a war-file. But it seems to be just as the original one that was packed into the war file. Does anybody know, how to prevent this error? Thanks in advance, Holger
