  • The Axis2 Quality of Services UI to apply security policies, throttling and caching has been removed from the management console. For information on how to apply security, throttling and caching, see the following:
    • The recommended approach to apply security to a proxy service is via WSO2 ESB tooling. For instructions on the process of applying security to a proxy service, see Applying Security to a Proxy Service.
    • The recommended approach to enable throttling is to use the throttle mediator.
    • The recommended approach to enable caching is to use the cache mediator.
  • The EHcache based implementation has been removed from ESB 4.9.0 and above due to distributed caching related issues with EHcache. We have moved onto a hazelcast based caching implementation with ESB 4.9.0 onwards, and officially support the hazelcast based caching implementation.


    The EHCache jar that was shipped with ESB 4.8.1 and older versions under the <ESB_HOME>/repository/components/plugins directory is not shipped with ESB 4.9.0 and later. If you do want to use a third party jar like EHCache jar with ESB 4.9.0 and above, you can add the jar to the <ESB_HOME>/repository/components/lib directory.
