Which version of JBoss and Java do you use? And did you do any changes to the clean installation of JBoss?

By the way, why do you want to use the web-console? By web-console, i guess you mean http://localhost:8080/web-console. The web-console hasn't been maintained for some time now and isn't very useful.

The your problem is here

org.apache.jasper.JasperException: File "/WEB-INF/tlds/webconsole.tld" not found

Did you modified something?

[verdi2000]

hi,

I've got version 4.0.3
I didn't modify anything!

Why I want to use the webconcole? I need some performance data form jboss and I hope to get them from the web console!
There is a file missing! I noticed that, too. Can I install the web console afterwards?
Or can I get my performance data another way?

[erasmomarciano]

mmm
You check $yourcontainer/deploy/management/console-mgr.sar/web-console.war/ WEB-INF/web.xml

you find this tag

<taglib>
 <taglib-uri>/webconsole</taglib-uri>
 <taglib-location>/WEB-INF/tlds/webconsole.tld</taglib-location>
 </taglib>

Can I install the web console afterwards?

You can try to reinstall JBOSS or find this file webconsole.tld and punt in this directory $yourcontainer/deploy/management/console-mgr.sar/web-console.war/WEB-INF/tlds/
ot reinstall web-console.wa



Performance ?
what do you mean?

[verdi2000]

Performance Data:

User Statistics,
Memory, I/O and any other usefull data!

I got performance problems on my system and I want to check if my hardware is good enough...

[erasmomarciano]

If you want to check the garbace collection you can use the following tools:
HPJMETER JCONSOLE
While if you want to check , RAM, HARDISK,CPU you should use the tools specifies

[verdi2000]

Hmm, I think I have to test this first!

By the way: where can I find teh user statistics?
This would solve my urgent question!

How about the recently released Embedded Jopr http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4184364#4184364
