Unable to start JIRA server with AJP protocol

Hi Support Team,

I have installed, started and browsed well with the JIRA 4.3.3 application, when i started with HTTP protocol. But when i replace the connector from HTTP to AJP protocol, i'm unable able to browse the application in browser.

It returns the below errors:
