Cluster based AS deployment issues and suggestions

AS does the 2.3 dtd requirement. web app xml DD specifies file protocol
based DD $install_home/lib/dtds/* and http://java.sun.com/dtd/

It looks for local file system based on file protocol first,
It then looking for http://java.sun.com/dtd/

This works for single host and instance based AS deployment.

What you explain works for the case if single
host and AS instance based deployment. However, for the cluster based deployment
over remote node agent, you can not require (1) DD path exists on DAS host pertaining
to file protocol specified in DD xml (2) FQ URI is accessable within firewall policy.

My suggestion is to cluster based deployment to stream over the DD from node agent
host to DAS in oder to fetch DD content for deployment further processing.
