Servlets won't load after deployment

MY webapp works on my localhost but after deployment I get an error 
instantiating HttpServlet class even though I have the servlet.jar in 
the CLASSPATH.  Here are the CLASSPATH and catalina.out.
Does anyone know what I am doing wrong?
thanks,
Phil

CLASSPATH=:.:/usr/java/mysql-connector-java-2.0.14-bin.jar:/usr/java/jdbc7.2dev-1.2.jar:/home/catalina/jakarta-tomcat/common/lib/servlet.jar:/home/hardwoodthunder/jakarta-tomcat/common/lib/servlet.jar:/usr/java/mm.mysql-2.0.11/mm.mysql-2.0.11-bin.jar

Filip,
Thanks for the suggestion. I tried it but get the same problem.
Now I'm wondering if the connector to tomcat is working because of this 
error message:

thanks,
Phil

RE: Servlets won't load after deployment

Posted by "Filip Hanik (lists)" <de...@hanik.com>.

remove all that stuff from your classpath.
do this

export CLASSPATH=""
./startup.sh

and it should work, the startup scripts are setting the classpath, and so
does tomcat when it startup,
you placing stuff in the system classpath will only mess things up :)
