You can also use request.setAttribute() in the first servlet to store objects
in this request, and request.getAttribute() in the second servlet to retrieve
them. This is particularly useful if you do not need these objects after
finishing the current request, because they will get thrown away for you. The
session approach is better if you need to keep them after you are through with
the current request.
NOTE: request attributes were added in the 2.1 version of the servlet API.
If you're using a servlet engine based on a previous version of the API, this
won't work.
