JDBC driver,Tomcat,DB2 Problem

Hi,I am trying to access DB2 with JDBC driver in the
tomcat3.3 server.Following is the code:
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
conn = DriverManager.getConnection(
"jdbc:db2:BankDB",userid,passwd);
I also include the db2java.zip in the CLASSPATH.
When I run a simple java application with above code
to test the database access,it works.But when I
use it in a servlet from Tomcat,I got the
ClassNotFoundException Error.It seems the server can
not get the driver.
I checked old posts in JavaRanch and still can not
get a clear solution.I also ran the usejdbc2.bat in
DB2.
Any advice?
Do I need to install the DB2 client in the machine?
Right now the DB2 server,Tomcat server and all programs
are in the same Win2000 box.
Thanks

Are you using Tomcat 4.x. I had a similar problem when accessing my Access database. The problem is with the classpath settings.
Here is what I suggest you try out. In the bin directory you should see catalina.bat. Open it up. Under that you should see the following lines
rem ----- Set Up The Runtime Classpath ----------------------------------------
set CP=%CATALINA_HOME%\bin\bootstrap.jar;%JAVA_HOME%\lib\tools.jar
if "%JSSE_HOME%" == "" goto noJsse
set CP=%CP%;%JSSE_HOME%\lib\jcert.jar;%JSSE_HOME%\lib\jnet.jar;%JSSE_HOME%\lib\jsse.jar
:noJsse
set CLASSPATH=%CP%
*Replace the last line with*
set CLASSPATH=%CP%;%CLASSPATH%
Let me know if this works.

Try renaming the zip file to jar.
