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:
