I've had some problems loading servlets, so I tried a basic HelloWorld just
to make sure everything was working.
java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet
servlet-api.jar is in $CATALINA_HOME/lib just like it's supposed to be. All
of the example JSPs and servlets work fine.
Check you didn't add servlet-api to your webapp classpath. The
servlet-api must *not* be present in WEB-INF/lib

Thanks for your reply David.
For this servlet there's nothing in WEB-INF/lib. If it was a standalone
Java app, I guess the CLASSPATH would definitely be the first thing to
check. Is there a way to check the classpath that a servlet is using when
it's executed by Tomcat's VM?
Thank you,

Check also it's neither in shared/lib and that there is no CLASSPATH
defined (tomcat handles all by itself classpath).
There wouldn't be a shared/lib, since this is Tomcat 6

I do not doubt that. However, depending on what O.S. you are using you need
to check your JAVA_HOME environment entry or even windows registry.

if you are running the Sun VM, why is this in your stack trace?
at gnu.java.lang.MainThread.run() (/usr/lib/libgcj.so.6.0.0)
my guess is that you forgot to do this
export PATH=$JAVA_HOME/bin:$PATH

The stack is the one that Tomcat has print before the remove of gcj.
But the error is still here also after the remove.
