Hi!
With the advice I got from
<http://www.coreservlets.com/Apache-Tomcat-Tutorial/tomcat-5.5.html>,
I successfully installed Tomcat 5.5 on my computer
(Ubuntu 7.04). I verified that I can a) start the
server, b) access my own HTML and JSP pages, and c)
compile and run simple servlets.
I created a development dir in my home directory,
/home/tuope/src/web/servlets. I have created, too,
some shortcuts there:
catalina.sh -> /usr/local/bin/tomcat/bin/catalina.sh
shutdown.sh -> /usr/local/bin/tomcat/bin/shutdown.sh
startup.sh -> /usr/local/bin/tomcat/bin/startup.sh
Having done the tests mentioned above, I issued
$ sudo sh ./shutdown.sh
and then
$ sudo sh ./startup.sh
The result was that *I can no longer run any
servlets*. I get this message
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error
() that prevented it from fulfilling this request.

note The full stack trace of the root cause is
available in the Apache Tomcat/5.5.23 logs.
I rebooted the computer. Didn't help.
$ echo $JAVA_HOME
/usr/lib/jvm/java-6-sun-1.6.0.00
$ echo $CLASSPATH
/usr/local/bin/tomcat/common/lib/jsp-api.jar:/usr/local/bin/tomcat/common/lib/servlet-api.jar:/home/tuope/src/web/servlets:.
Does anyone know what might be causing this odd
behavior? I am unarmed. :-(
