Answer 1

It was happening because of some strut 2 interceptor. At least i know rason know and can work on that.

Answer 2

The 503 Service Unavailable error is an HTTP status code that means the web site's server is simply not available right now. Most of the time this is because the server is too busy.

Note: Sites that use Microsoft IIS may provide more specific information about the cause of a 503 Service Unavailable error by suffixing a number after the 503 as in HTTP Error 503.2 - Service Unavailable which means Concurrent request limit exceeded.
