Option to turn off codebase lookup during resource requests

Name: gm110360 Date: 01/20/2004


FULL PRODUCT VERSION :
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Not webserver dependent, tested on IIS and iPlanet

A DESCRIPTION OF THE PROBLEM :
There is currently no way to tell the plugin to restrict loading of resources to files specified in the <cache_archive> tag. The result of this is that in internationalized applications where a resource bundle for a particular locale does not exist, the plugin wastes a lot of time going back to the web-server to hunt for it. The fact that these lookups happen in sequence causes massive delays in high-latency environments.

You could argue to not use resource bundles in such environments : however, there's no control over when third-party libraries do.

There should be a <cache_option> value="Plugin_Only" or some equivalent to tell the plugin only to load files specified in the <cache_archive> tag and not even
try to get resources on a file-by-file basis.

For example, here is some output I got from my plugin :

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use any applet that uses ResourceBundle.getBundle(name, locale) without including the resources for that locale in the archive. Turn on plugin tracing

ACTUAL -
Multiple requests to the web-server for non-existent resource bundles

REPRODUCIBILITY :
This bug can be reproduced always.
