Hi,

In our Application We are having an individual Servlet for each of the Functionality.
All these servlets were initially designed with out considering the aspect of Authorization.

Now we have a requirement to perform the Authorization for each of these servlets before the request for them is processed at server side.
To achive this I need to change all of my existing servlets to implement the authorization logic in them.
We are using the servlet engine 2.2 .. so we are not able to use the Filters Concept.

Is there any alternate way to do this with out changing all of the servlets?

Many Thanks,
K.Chandra.

You can use form authentication and protect a URL by configuring the same in web.xml

Hi Sebastian Janisch,

Currently We don't have the option to upgrade our server to a new version.
So I need to look for an alternate solution in the Servlet 2.2 version itself.

Hi Deepak Bala,

Could you please explain me about the form authentication mechanism and the web.xml configuration to protect a URL?

Hi Deepak,

Thank you very much for the link provided.

But in our application we are already having an custom authentication mechanism using the TAM (Tivoli Access Manager).
So i can't write one more Authentication mechanism using this form based authentication.

Is there any way to Write Filter Kind of Functionality in Servlet 2.2 version?

I believe the support for filters started with the 2.3 version of the servlet spec. As posted, using a filter is one of the easiest ways to achieve the functionality that you need.

Hey,

I know that spring security is very pluggable and works well even in applications that do not use Spring.
It also allows you to define access to certain URLs based on roles that you can define.
