Websphere Plugin For WAS 4.0 and WAS 5.0

| We will be deploying 2 WebSphere Enterprise Applications. One will run under
WAS 5.0. The other is running under WAS 4.0. We will not have time to port
the WAS 4.0 application prior to deploying the new application under 5.0.
Can I configure the web server with websphere plug-in to route requests to
both versions of app servers ?

| You should be able to run the WAS 4.0 (J2EE 1.2) application on WAS 5.0
without modification. In fact, you should be able to deploy the exact same
EAR. You'll have to set up v4 data sources and such...
This *should* work, but you *should* test it first. In the end, your
configuration will be much simpler and the footprint on your hardware much
smaller...

| You could edit the plugin-cfg.xml and merge (and adapt) the delta of the
plugins in one of the two server. As a result, the plug-in would have
knowledge that there are several application instances to load-balance. But
then you can't regenerate the plugin automatically (otherwise, you'd
overwrite the changes).
I recal that the plugin adds a set of technical headers (you can see them in
the log when you turn the plug to trace mode -> $WSxx). Maybe the WAS 5
plugin would send unexpected or unproperly formatted headers to WAS 4, which
wouldn't like them. Maybe there are other changes, since the IHS module is
not the same in WAS 5 than in WAS 4. But maybe it won't make a difference.
Many maybe as you can see :-). So, I'd imagine that it's not impossible, but
you'll want to test this seriously...
Let's know the result.

| InfoCenter has information on this topic. Be aware that if both
applications have the same
context root, the plugin will only route to one of the applications.

| Maybe it's the same information (I didn't check the InfoCenter yet), but you
may find usefull the RedBook "Migrating to WebSphere V5.0 - An End-to-End
Migration Guide" (sg246910), as it has a topic on this (Chap. 5).

| I was wondering if you managed to configure the websphere plugin to use both
WAS4.x and WAS5.x?
I am having trouble doing so. The problem is with WAS5.0 not being
recognized by the webserve.
We had an existing WAS4.0 application in production and i am trying to add
WAS5.0 to it and use the existing webserver that came with WAS4.0
(SF99156-09 June 27, 2002) and plugin.
The platform is iSeries and the infocenter did not have anything specific
to this problem.
The plugin's native.log gives an error Faild to connnect to app server, OS
err=3447
Thanks for you help.

| I can't speak for the iSeries platform problem that you are having.
If you want a webserver to serve requests to both WAS 4.x and WAS 5.x you
must use the WAS 5.x plugin modules. The reason being that the WAS 5.0
plugin-cfg.xml file format is differently than WAS 4.0 plugin-cfg.xml file.
The WAS 5.0 plugin can understand both 4.0.x and 5.0.x formats.
