"org.jboss.logging.util.OnlyOnceErrorHandler" object is not

[sramired]

Hello
I am seeing exception when Jboss4.0.2 startsup. Looks like this issue is related to Logging, but after this my .war gets loaded properly and logging is working.
Kindly let me know if this is something to be fixed.

I believe I had the same problem, the behavior of the class loader changed in 4.0.2.

At the bottom of JBAS-1691 is a solution: switch back to the old behavior by changing jboss-service.xml.

http://jira.jboss.com/jira/browse/JBAS-1691

To revert to pre-4.0.2 config use:

<attribute name="Java2ClassLoadingCompliance">true</attribute>
<attribute name="UseJBossWebLoader">true</attribute>

[sandello]

I tried all combination of

<attribute name="Java2ClassLoadingCompliance">true</attribute>

<attribute name="UseJBossWebLoader">true</attribute>

<attribute name="Java2ClassLoadingCompliance">false</attribute>

<attribute name="UseJBossWebLoader">false</attribute>

and in all case I got different errors. What I did whong?

[sandello]

I use JBoss 4.0.3sp1

[sandello]

Problem solved: I removed log4j.jar from app.wap:/WEB-INF/lib

Very good, Sandello. I had this problem, I removed log4j.jar from my application on Jboss and it startup without problem.

[binodkumarsuman]

Nice, very nice. Simply I removed all the Log4j*.* from WEB-INF\lib of all the application inside the deploy folder. It is working fine.
Thanks.

Which version of JBoss? For JBoss-4.2.x, have a look at http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4125552

i remove log4j.jar but jboss don't need the jar file for any other operation?
