request.getSession() vs getThreadLocalRequest().getSession()

What is the difference between 

request.getSession()

and 

getThreadLocalRequest().getSession()

The application I am maintaining appears to use the first for straight Servletsand the second for anything implemented via GWT-RPC which itself extends servlet.

Solution

  • They both return the same thing. GWT simply stores the request sent in from the servlet into a thread local so that you don't need to pass it around in every method call and still have a separate request for each invocation.
