CAUSE:
A problem has been encountered when you integrate Tomcat using the mod_jk plug-in with the Apache Web server. Tomcat 3.3 introduces the new mod_jk plug-in, which is a replacement to the older mod_jserv. It provides two possible protocols: Ajp12 and Ajp13, the default being Ajp13.
The problem does not happen when using the Ajp12 protocol, nor with the mod_jserv interface.
You can define the protocol in the mod_jk.conf file for each instance of an application (/examples, /admin, /aia).
FIX:
To continue using the mod_jk plug-in, change the protocol used by Aia to Apj12.
a) Edit Tomcat's mod_jk.conf referenced in the Apache httpd.conf file.
For example: Find the following line in the Apache httpd.conf to determine the location of the mod_jk.conf file for the Tomcat:
Include C:/Tomcat/conf/tomcat-apache.conf
b) In the mod_jk.conf modify the defination for the /aia instance.
For example:
JkMount /aia ajp12
JkMount /aia/* ajp12
