I had a similar error when i tried to deploy a simple JSP for JBoss in a Tomcat
manner, means to extend the server.xml by a context-tag. The JSP has been
transformed to a servlet but this servlet i've been not able to get it compiled
automatically by JBoss, but only by hand with an appropriate
Komo, thank you for your advice.
After I have added the servlet.jar in my classpath, the mentioned problem was
solved. My system variables now is set like this:
JAVA_Home: c:\Program Files\Java\jdk1.5.0_01
JBOSS_HOME: C:\jboss-4.0.0
Path=c:\Program Files\Java\jdk1.5.0_01\bin
