Peter Petrovics [http://community.jboss.org/people/szerintedmi] created the discussion "exception from CacheJmxWrapperMBean.getCache()" To view the discussion, visit: http://community.jboss.org/message/547863#547863 -------------------------------------------------------------- I'm trying to reach the same cache from two different webapps running on the same Tomcat. The first time it starts I'm registering with the following code: {code} jbossCache = new DefaultCacheFactory().createCache(configFile); cacheJmxWrapper = new CacheJmxWrapper(jbossCache); ObjectInstance oi = mBeanServer.registerMBean(cacheJmxWrapper, on); // tryied this way too: //JmxRegistrationManager jmxRegManager = new  JmxRegistrationManager(mBeanServer, jbossCache, on); //jmxRegManager.registerAllMBeans(); log.info("Cache started. MBean objName: " + oi.getObjectName()); {code} I try to get a reference through JMX with this code: {code} mBeanServer = ManagementFactory.getPlatformMBeanServer(); cacheJmxWrapper =                         (CacheJmxWrapperMBean) MBeanServerInvocationHandler.newProxyInstance(mBeanServer, on,                         CacheJmxWrapperMBean.class, false); Object o;   // just to show the issue o = cacheJmxWrapper.getCache(); {code} I receive the following exception from the last line: {code} java.lang.ClassCastException: org.jboss.cache.invocation.CacheInvocationDelegate cannot be cast to org.jboss.cache.Cache         at $Proxy17.getCache(Unknown Source) {code} I tried several different methods to register/get reference. Am I missing a point or is it a bug? As I read JNDI would be a workaroun but can't find proper description how to setup (and setting on production server would be a bit complicated because of restricted access). I there any other way to reach the same cache from different webapps? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/547863#547863] Start a new discussion in JBoss Cache at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
