Hi Marco,
hmm, it should work with these changes. I've tried it with the
mini-servlet attached to this mail. It deploys in Geronimo 2.1 without
errors and works as it should. If this is still not working for you,
then I don't know what else it could be.

Hi Janko,
Thanks for your quick response. I changed the lookup as you suggested in
option 1, but I still have the exception (except it now tells it cannot find
system-info). Any more ideas or things to check ?
Kind regards,
Marco

Hi Marco,
the line "<ref-name>system-info</ref-name>" defines the local name of
the ServerInfo object in the context of your WAR. Therefore, you can
either
1) keep the ref-name and try to lookup "java:comp/env/system-info", or
2) keep the lookup and change the line in geronimo-web.xml to
<ref-name>ServerInfo</ref-name>.
I hope I could help you!
Regards, Janko

I am trying to get some information for the ServerInfo object, i have
added
the gbean to my geronimo-web.xml:
<web-app xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-1.1";>
<context-root>/navi</context-root>
<gbean-ref>
<ref-name>system-info</ref-name>
<ref-type>org.apache.geronimo.system.serverinfo.ServerInfo</ref-type>
<pattern>
<name>ServerInfo</name>
</pattern>
</gbean-ref>
</web-app>
and a try to get a handle of the serverinfo in my servlet by:
serverInfo = (ServerInfo)(new
InitialContext().lookup("java:comp/env/ServerInfo"));
but this throws a NameNotFoundException.
What am I doing wrong in the situation above ?
Kind regards,
