Tomcat 3.3 & JBoss & mod_jk

[LAU ENG HUAT]

Hi,
I'm a newby. I have installed Tomcat 3.3 and  manage to get it working.
When I read the doc on JBoss integration with Tomcat, it mention about
the
1. Servlet Api . Currently I could not find the latest Tomcat 3.3
servlet api. Can I used the Tomcat servlet 3.2.3. api ?
2. The example given is using the JServ and mention about using
wrappers. I'm using mod_jk. Can anybody help me on this ?

Thanks for your help
