[jboss-user] [JBoss Cache Users] - java.lang.NoClassDefFoundError: org/jaxen/VariableContext ex

Monday, 9 November 2009

Hi, 

I am getting a java.lang.NoClassDefFoundError: org/jaxen/VariableContext exception when
using JBoss Cache after a period of inactivity. I hope you can help me.

Regards,

Sean.

Here is the problem in detail:

The scenario is as follows:

1. - create cache

private MBeanServer server = MBeanServerLocator.locateJBoss();

private TreeCacheMBean cache = (TreeCacheMBean) MBeanProxyExt.create(TreeCacheMBean.class,
"jboss.cache:service=TreeCache", server);

2. Load various data into the cache

3. Access Seam based web application that reads some of these data.

4. Leave webpage inactive, at 5 minute intervals the exception message at the end of this
post is created.

- I'm aware that the root exception (Caused by: java.lang.NoClassDefFoundError:
org/jaxen/VariableContext) may be a red herring/not really the problem judging by this
issue report: 

https://jira.jboss.org/jira/browse/EJBTHREE-1297. 

Jaxen.jar is definately in my classpath.

- My environment is:
JBoss Cache 1.4.1
JBoss 4.3
Seam 2.1.2
Windows XP

- I have configured a cache loader to use a data source for a MYSQL database (MYSQL 5.0)

- I am not using a clustered environment at present, and have therefore set attribute
name="cacheMode" to equal "LOCAL" in my JBoss cache configuration file
(jboss-service.xml)

- The problem occurs whether or not I set passivation to false in my Jboss-service.xml

- Here is some debug information about my cache:

eviction policy class = null
eviction thread wakeup interval =  0
FetchInMemoryState = true
NumberOfAttributes = 37
NumberOfNodes = 14
isUsingEviction = false
isUsingMultiplexer = false

HERE IS MY JBOSS-SERVICE.XML
