Crazy java.lang.NoClassDefFoundError

jpviragine Oct 31, 2006 6:53 AM

Hi, I?m get crazy with this stuff:

Sometimes I start JBoss (jems 4.0.4 GA ? Seam 1.1 and MyFaces 1.1.4) and get a java.lang.NoClassDefFoundError (as shown follow) when run my application.
So, I shutdown JBoss and start it again and suddenly all works fine.
I don?t think that?s a classpath issue.

Anyone have any idea what?s happens?

Thanks in advance.
P.S. Sorry for my English. :-)

My components.xml:

<components>

 <component name="org.jboss.seam.core.init">
 <property name="jndiPattern">elo/#{ejbName}/local</property>
 </component>

 <component class="org.jboss.seam.core.Jbpm">
 <property name="pageflowDefinitions">
 pageflow.jpdl.xml
 </property>
 </component>

 <component
 class="org.jboss.seam.selectitems.SelectItemsPersistenceConfig">
 <property name="persistenceUnitJndiName">
 java:/selectItemsEntityManagerFactory
 </property>
 </component>

 <component class="org.jboss.seam.core.Ejb" installed="false" />

</components>

I think JDK1.5 is not ready for primetime. Try JRockit. It fixed my "PermGen space" classloader issue.

monkeyden,

I?m trying using JRockit but the error persists.

Another idea?

Thanks for your help.

I would:

1. Post the code for that component
2. Drop breakpoints in Component.instantiate(), for every case in the switch, Component.newInstance() and Component.initialize() to see what is happening.

This is actually because of a well-known memory leak in Tomcat, AFAIK.

Hi, I?ve solved my classloading problems:

A few days ago I?ve changed my package generation and remove seam library (and others libraries) from my ear and put them into JBoss server\default\lib. This causes a random classloading issues.

Moving libraries back to my ear (as all seam examples) the problem has been solved.

IMHO, maybe it should be interesting to put *explicit* in doc or FAQ the right location to put seam and other libraries.

Cheers.

Why don't you add this to the Seam Problems FAQ on the wiki.
