Context init parameters -- attached with web application...
Servlet init parameters -- attached with a specific servlet...

Attributes which will be shared by servlets of a particular Web application...

They are attributes of the web application. Data items which are specific to the web application as a whole.

Are you guys saying that it is the data that is common to the entire web app???In that case how is it different from context init parameters??Also i think now i dont really understand what an attribute is.So what is an attibute exactly??

Thanks for all the help.

If by "attribute" you mean scoped variables that are set and fetched from the various contexts using setAttribute() and getAttribute(), then they are very different from context parameters.

Context parameters are set in the deployment descriptor and are static.

Scoped variables places in application context are set by code and can be changed at any time.

A better and unambiguous term is scoped variables.
