How can I get a 503 status code in tomcat.503 means - service not available , but how can I achieve this in tomcat.Do I have to configure MBeans for making individual services unavailavble and avaialble again without shuting down the tomcat and remotely.

One of the conditions where 503s happen is if there are more clients accessing a server than it can handle, e.g. if its thread pool is exhausted.

If you want to send 503s from your web app, you can do so with the HttpServletResponse methods setStatus and sendError.

If I want to do something like this...I want to have a service registry and control the registry using an mBean.
And getRegistry would check in the cache whether the service is available or not and the cache can be controlled by the mBean.

boolean serviceAvailable = getRegistry(serviceName);
if(serviceAvailable == fasle)
//send errorCode 503
else
//continue
