Configuring mod_jk

HI all

I am trying to configure mod_jk with my newly installed jboss-ewp-5.1.2 using the native components which ship with this release on the download page.I have copied the mod_jk.so to my apache's modules directory when i try to start apache i am getting the following error:

httpd: Syntax error on line 200 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_jk.so into server: /etc/httpd/modules/mod_jk.so: undefined symbol: ap_get_server_description
 

My environment details are as follows:
