Thanks for all the responses
I am wondering what spec says about it and API doesn�t say that RequestDispatcher returned by servletContext is not
Thread Safe. I am using
Tomcat and hence can know whether I can do it or not by looking in to the RequestDispatcher implementation. But that makes my code vendor specific and didn�t want to do something like it.
I am using at as read only inside the Service Methods by assigning it once in the init Method.
Thanks,
Satheesh.
