and some objects were put into mymodel,Would you tell me how to get the value of mymodel from bController??????

Hi,
because you use a redirect instead of a forward, all request attributes in your
mymodel Map are encoded in the URL. (key=value pairs).

You can retrieve them with request.getParameter("key") in your controller.
If you don't want to encode everything in the URL or if you want to ship complex classes like your JavaBeans you can save them in the session in controller a and retrieve them back in controller b.

If redirection is not a must, you can of course forward the request from controller a to b. I think InternalResourceView is capable of forwarding requests between controllers.

HTH, Chris
