Statement of support regarding Sun ONE web servers with WebSphere
Application Server:
- IBM supports the use of the WebSphere V4.0 plug-in
with Sun ONE 4.1 and Sun ONE 6.0 web servers
- IBM supports the use of the WebSphere V5.0 and V5.1
plug-in with Sun ONE 6.0 web server
- IBM officially does not support Sun ONE 4.1 web
server with WebSphere V5.0 and V5.1 releases
- IBM officially does not support Sun ONE 6.1 web
servers with WebSphere V5.0 and V5.1 releases, because
neither V5.0 nor V5.1 were tested with the Sun ONE 6.1 plug-in. IBM
provides support for it only on a best-effort basis. Customers should
re-create the same plug-in problem with a supported SUN ONE configuration
before reporting any Sun ONE 6.1 WebSphere plug-in defect to IBM.
Before calling IBM for any plug-in support issues, IBM recommends that you
first install the latest cumulative plug-in fix.
To download the latest WebSphere Cumulative plug-in fixes, go to:

- Cumulative plug-in fix for V5.0

Background:
Starting with PTF3 for WebSphere Application Server (V4.0.3), IBM
included support for Sun ONE 6.0 web server. Sun ONE 6.0 is supported in
WebSphere V5.0 and V5.1 in the GA releases.
Sun ONE web server Enterprise Edition V6.0 plug-in directives are now
split between the magnus.conf and obj.conf files:
- init functions, such as those used to load the WebSphere
4.0 plug-in, are configured in the magnus.conf file
- service as_handler functions remain in the "default
object" stanza of the obj.conf file
Note: It is still a requirement that the service as_handler function be
the first service function defined in the default object stanza.
Steps for automatic configuration of Sun ONE plug-in for
WebSphere:
You can perform a Sun ONE upgrade automatically by:
- Uninstalling all WebSphere Application Server fix packs & fixes on
Sun ONE server
- Follow instructions to uninstall Sun ONE 4.1.x
- Follow instructions to install Sun ONE 6.0.x
- Install WebSphere fix pack (this will install the plug-in for Sun ONE
6.x)
- Install any needed WebSphere fixes
- Review all plug-in entries in Sun ONE configuration files
- Start Sun ONE & WebSphere Application Server
Steps for manual configuration of Sun ONE plug-in for WebSphere:
- Verify that your current WebSphere Application Server configuration is
running.
- Stop Sun ONE and WebSphere Application Server
- Save magnus.conf and obj.conf files from the Sun ONE 4.1.x
configuration
- Follow directions to uninstall Sun ONE 4.1.x
- Follow directions to install Sun ONE 6.0.x
- Manually add the needed directives to magnus.conf & obj.conf. (See
"Manual upgrade of SunOne plug-in in the web server configuration
files" for details)
- Start Sun ONE and WebSphere Application Server.
Manual upgrade of Sun ONE plug-in in the web server configuration
files:
When upgrading from Sun ONE 4.1.x to Sun ONE 6.0.x, some of the
WebSphere Application Server plug-in entries that were in the obj.conf
files in Sun ONE 4.1.x need to be moved to magnus.conf:
Init fn="load-modules" funcs="as_init,as_handler,as_term" shlib= ...
Init fn="init_exit" bootstrap.properties= ...
The rest of WebSphere plug-in directives will stay in the obj.conf:
Service fn="as_handler"

scratch, go to this Web site:

Conclusion
This document should be used as a guideline toward the migration of
WebSphere 4.0 plug-in from Sun ONE 4.1.x to Sun ONE 6.0.x web server.
You can review attached sample Sun ONE 4.1.x & Sun ONE 6.0.x
configuration files with WebSphere 4.0 plug-in module on a Unix platform.
The lines added by the WebSphere install script are preceded with a "*" so
they stand out. The actual configuration directives are identical for the
two versions of Sun ONE, the only change is the two lines responsible for
getting the plug-in loaded and initialized have been moved from the
obj.conf to the magnus.conf in Sun ONE 6.0.x
You have to disable completely the Servlet Engine/Java in Sun ONE web
server on the global level. The Servlet Engine/Java is enabled by default
in the Sun ONE 4.1.x & Sun ONE 6.0.x web server & it collides with
the WebSphere Servlet engine.
