JBoss configuration problem for 8009: Invalid message received with signature 18245

Question

JBoss 5.1.0 is configured for Ajp on port 8009 as follows in /jboss/server//deploy/jbossweb.sar directory:

  <Connector protocol="AJP/1.3" port="8009" address="${jboss.bind.address}"
     emptySessionPath="true" enableLookups="false" redirectPort="8443" maxThreads="200" connectionTimeout="60000" />

After starting jboss and deploying war, following error comes up while accessing the servlet on 8009 - [AjpMessage] Invalid message received with signature 18245

Any help will be quite helpful.
