It is not loading servlet.jar cos that is only there in the tomcat lib. Just shove a copy of that under JBOSS_HOME/lib/ext and it should find it on restart. Vinay

Can someone please help me with this exception I'm getting from my servlet?

I'm running on Linux with Apache 1.3.19 delegating to Tomcat/Jboss. I'm
running
my own version of tomcat (instead of the JBoss-Tomcat distribution) because
I
need a virtual host configuration through apache.
Jboss reports the TOMCAT_HOME/lib/servlet.jar being added to the classpath
extension when it's started.
[Classpath extension] Added
library:file:/usr/local/jakarta-tomcat-3.2.1/lib/ant
.jar
[Classpath extension] Added
library:file:/usr/local/jakarta-tomcat-3.2.1/lib/jax
p.jar
[Classpath extension] Added
library:file:/usr/local/jakarta-tomcat-3.2.1/lib/ser
vlet.jar
[Classpath extension] Added
library:file:/usr/local/jakarta-tomcat-3.2.1/lib/par
ser.jar
[Classpath extension] Added
library:file:/usr/local/jakarta-tomcat-3.2.1/lib/web
server.jar
[Classpath extension] Added
library:file:/usr/local/jakarta-tomcat-3.2.1/lib/jas
per.jar
[Classpath extension] Added library:file:/usr/local/jdk1.2.2/lib/tools.jar
The servlet works fine when run via tomcat alone, but not with the
jboss/tomcat
combination.
Is there something else I should check?
Thanx for your help.
Norton
