Hello Mikael, if i read u right u mean no WEB-INF? w/o this very special directory some of tc scope has been chopped off. how, do u get the jsp/servlet to work? how do u have docbase defined in ur server.xml? tc needs docbase to know where to look in the directory hierarcy. also, i assume u r not using a web.xml? u have a very unusual environment. can u send any inkling of ur directory hierarchy? say, something like: $CATALINA_HOME/<what?>... thanx, david.

$CATALINA_HOME/webapps/ROOT/WEB-INF/classes
and my working servlets classes are located in
$CATALINA_HOME/webapps/ROOT/WEB-INF/classes
and the jsp source files in
$CATALINA_HOME/webapps/ROOT

Hello Mikael, u r using the docBase=ROOT i assume uncommented in server.xml. though this is ok it is unadvisable. for a much more satisfying development environment u should seriously consider doing things the way the tc gurus have generated the .war for the /examples webapp. if u r familiar w/ the ant build development tool then u r on ur way just study the build.xml file the /examples webapp and make a modified version 4 ur own webapps. in case u r not familiar w/ ant the go back to jakarta-tomcat.org and study what they have to say about building a rock solid development system. by the way this works me and i have used many "ide's" and contrived development systems that try to hide the xml config in the servlet server/j2ee development environment. the java/j2ee world has really been very well thought out and any project can be developed using just four files: build.xml, .ear, .war, and .jar. hope this helps, david.
