ClassNotFoundException when class is present in WEB-INF/lib

[advaittrivedi]

Hi,
This is wierdest CNFE I have ever encountered. I am using JBoss Portal 2.6, JBoss AS 4.0.5 GA.

I have a war file which contains acegi-security-1.0.1.jar in WEB-INF/lib
This file has a class: org.acegisecurity.userdetails.UsernameNotFoundException. But still I get ClassNotFoundException: org.acegisecurity.userdetails.UsernameNotFoundException when portlet is initialized at server startup

I have enabled logging of class loading in log4j. This is UsernameNotFoundException related logs from ucl.log:

Any idea, whats going on?

Advait-

You problem is tomcat isolated class loading (which btw is a good thing)

To fix this-

1/ Go to deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml

2/ Make the value of UseJBossWebLoader to "true" from its default value of "false"


Thanks

Hi Sohil,

I tried doing true, but this is even more catastrophic: I have cas.war (http://www.ja-sig.org/products/cas/) deployed on my JBoss Portal, for SSO. It has common-logging and log4j JARs. If I make above to "true", then following is coming while server startup:

11:03:49,083 INFO [PortletAppDeployment] Parsing jboss-portlet.xml/portal-core
11:03:50,005 INFO [TomcatDeployer] deploy, ctxPath=/cas, warUrl=.../deploy/cas.war/
11:03:51,036 INFO [[/cas]] Initializing Log4J from [classpath:log4j.properties]
ERROR: invalid console appender config detected, console stream is looping

See this: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=111078
And the start up halts :(
So I never reach to the point where my original problem starts.

Thanks & Regards,
Advait

Hi Sohil,

I ended up with another problem. I have JB AS 4.0.5_GA and JBoss Portal 2.4 on top of it. I have pebble.war which contains WEB-INF/lib/spring-dao-1.2.8.jar which contains TransactionAspectSupport.class. I have alfresco.war which contains WEB-INF/lib/spring.jar which also contains TransactionAspectSupport.class.

First I had, UseJBossWebLoader=false and Java2ClassLoadingCompliance=false, but then while deploying pebble.war it gave following exception:

java.lang.NoClassDefFoundError: net/sourceforge/pebble/web/action/ActionNotFoundException
java.lang.Class.getDeclaredConstructors0(Native Method)
java.lang.Class.privateGetDeclaredConstructors(Class.java:2328)
java.lang.Class.getConstructor0(Class.java:2640)
java.lang.Class.newInstance0(Class.java:321)

Then in changed UseJBossWebLoader=true. Result: pebble.war got deployed successfully but deployment of alfresco.war threw exceptions:

java.lang.NoSuchMethodError: org.alfresco.util.transaction.SpringAwareUserTransaction.doFinally(Lorg/springframework/transaction/interceptor/TransactionAspectSupport$TransactionInfo;)V
at org.alfresco.util.transaction.SpringAwareUserTransaction.commit(SpringAwareUserTransaction.java:420)
at org.alfresco.repo.transaction.TransactionUtil.executeInTransaction(TransactionUtil.java:186)

Please note that I dont have any spring related jars in JBOSS_HOME/server/default/lib

Thanks & Regards,
