What is JK v1.2?

In the simplest terms, the JK modules, or mod_jk, are conduits between a Web server and the Tomcat JSP/servlet container. They replace the previous Web server module, mod_jserv, which had many shortcomings. The new JK modules include support for a wider variety of Web servers, better SSL support, support of the AJP13 protocol, and support for the entire Tomcat series from 3.2.x to 5.x.
