I am using a Linux box, trying to do clustering using jboss and tomcat
I have two nodes on the same server. have edited the server.xml of both the nodes with the appropriate AJP port.

I have edited the httpd.conf, workers.properties and uriworkers.properties of the webserver.

webserver starts just fine. App server starts and is accessible when i try to access my application using the web server port.

however jus before the log says the app server is started, it throws some errors (pasted below)

23:05:01,247 ERROR [AjpMessage] Invalid message recieved with signature 18245


Now when i try to access the app, for ex: http://localhost:18109/petstore

The application page should be coming up, instead i see the AjpMessage
"ERROR [AjpMessage] Invalid message recieved with signature 18245"

I have been trying to resolve this, for a long time now.

Can anybody advice what can be done or what has to be done.

Any help will be much appreciated.

Many Thanks
