[Clustering/JBoss] - ConcurrentModificationException during session serialization
by stani0
I've initially posted this in the RichFaces users forum:
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=136368
I haven't got reply there so far and I'm unsure where is the exact problem so I've decided to post it here, too.
The problem as it seems to be is the web session gets modified while it is been serialized. Specifically the serialization of an org.ajax4jsf.util.LRUMap instance holding some JSF(?) state is failing with ConcurrentModificationException, so I've first thought it could be a RichFaces library problem.
This is my development configuration (1 node cluster):
JBossAS 4.2.2.GA
Seam 2.0.2.SP1
RichFaces 3.2.0.SR1
Sun's JDK 1.5.0_15
Windows XP Pro SP2
The same problem appers with 2 nodes configuration on FreeBSD 7.0 with Sun's JDK 1.5.0_11.
Tell me what info I could supply more to clarify the issue. Here's the full stack trace of the exception:
15:27:13,187 ERROR [JBossCacheService] externalizeSession(): exception occurred externalizing session SessionBasedClusteredSession[id: F3m44XY0NwX7HVPjsweIDw** lastAccessedTime: 1211977633015 version: 39 lastOutdated: 0]

[Beginners Corner] - Upgrading Xalan in JBoss 4.2.2GA with Xalan 2.7.1
by aipnext
What are the steps to upgrade build in version of xalan in Jboss 4.2.2GA from xalan 2.7.0 to 2.7.1.
I have tried replacing the xalan jars with newer version of 2.7.1, however, it stopped deploying my EJBs by giving following stack trace

The type-mapping in the -ds.xml seems to be ignored or atleast used only in some specific case. I tried using a datasource with some invalid type-mapping (example below) and the application deployed fine and i was even able to use the datasource in my application:
