Java EE (Java Enterprise Edition) General Discussion

Hi,

I installed Tomcat 5.5.10, Fedora Core 4 and JDK 1.5.0_04-b05 in my PC.

When I run Mozilla and type http://localhost:8080, the Tomcat page appears on the screen, but when I try to run the HelloWorld example, I see the following error mesage:

type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

In my etc/profile file, I added the following lines (I think they are required for javac):
JAVA_HOME=/opt/jdk1.5.0_04
CATALINA_HOME=/usr/tomcat/tomcat
PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$CLASSPATH:$CATALINA_HOME/common/lib/jsp-api.jar
export CLASSPATH=.:$CLASSPATH:$CATALINA_HOME/common/lib/servlet-api.jar
export JAVA_HOME CATALINA_HOME CLASSPATH PATH
export CLASSPATH=.:$CLASSPATH:/db4o/db4o-4.6/lib/db4o-4.6-java1.2.jar


Does anybody know what�s wrong?

Thanks
