Hello,

I have some issues when trying to run Axis2 version 0.94 in Websphere 6 wit=
h the security module engaged.

Please note that the services do not actually perform any encryption/signin=
g etc, the module is only engaged in the axis2.xml.


Problem no 1:
-------------

In Websphere 6 on WinXP.

1) Deploy one of the sample services included in the 0.94 release, I used M=
yService.aar.

2) Execute the service through a call from the client.

It works as expected returning a response.

Now trying to stop the Websphere windows service it fails with:=20
"Could not stop the IBM WebSphere Application Server V6 - XXX service on Lo=
cal Computer. The service did not return an error. ..."

To restart websphere I have to kill the process.
This has been verified on two different Websphere 6 installations.

If I do not execute any webservice calls the server can be restarted in a c=
ontrolled fashion.


Problem no 2:
-------------

The reason I am restarting the entire Websphere server in the first place i=
s that trying to restart the actual Axis2 webapp is failing for some=20

reason, after executing a webservice call.

The webapp restarts but is then broken and give me errors each time I send =
a web service request to the server.

If I disengaged the security module (remove the entry from axis2.xml) the w=
ebapp in Websphere can be restarted and will function properly.


Problem no 3: 
-------------

The reason I have to restart the webapp is that hotupdate is not working pr=
operly (I believe there is a Jira for this already).

In effect this means I have to force-kill my Websphere process each time I =
deploy/update a webservice which is not very nice.

Johan Andersson
