Hi, I am using Jboss cache searchable in my application. I have a method which I use to cache all that I need. I have exposed this from the JMX-console. The method, creates a singleton "Cache" and "SearchableCache" object and uses this to perform the caching. The method works fine if I have no "Configuration" element attached to it, but when I try to use a Configuration for my cache, I am getting a java.lang.ClassNotFoundException: org.jboss.cache.transaction.GenericTransactionManagerLookup I have tried to create configurations via both Java and xml variants. The interesting part to the whole thing is, I get this exception only when accessing the method from JMX. If I access from the app, it seems to work absolutely fine. I have tried using , the 3 transaction managers provided by jboss cache and also JTA. My app runs on jboss 4.05 and uses Spring for service, transaction and configuring JMX. Any help is appreciated.
