[jboss-user] [JBoss Cache: Core Edition] - Bad registration of class loader

[yair.zaslavsky]

Hi all, I have a class that wrapps "get" and "put" of TreeCacheMBean (The class gets an object of TreeCacheMBean using the code:

MBeanServer server=MBeanServerLocator.locateJBoss();
  | TreeCacheMBean cache=(TreeCacheMBean)MBeanProxyExt.create(TreeCacheMBean.class, "jboss.cache:service=TreeCache", server);
  | 
)
When i invoke the get and put methods I get the exception:

java.lang.RuntimeException: java.lang.ClassNotFoundException: No ClassLoaders found for: com.cellerium.logicsrv.logic.resource.data.BinaryResource

I did use "registerClassLoader" (in my wrapping class i have an init method that performs:

treeCache.registerClassLoader("/", this.getClass().getClassLoader());


Can anyone tell me why i am getting this exception?
