clarifying path for Redirect & Dispatcher

[Selvaraj Subramanian]

Hi All,
Correct me if I am wrong...

As per my understanding (using Tomcat),

sendRedirect()
==============
1)the path can be relative or absolute(htt://www.javaranch.com)
2)if its relative path & does NOT start with "/" then its considered as relative to the current URL path.
3)if its relative path starts with "/" then its considered as relative to the CONTAINER root.

RequestDispatcher obtained from request object
==============================================
1)can accept only relative path
2)the path CAN start with or with out "/"
3)the path is considered as relative to the current URL path

RequestDispatcher obtained from context object
===============================================
1)can accept only relative path
2)the path SHOULD start with "/"
3)the path is considered as relative to the current URL path

am I correct?

Dear Selva,

You are Correct as far as sendRedirect() is considered.

But

RequestDispatcher obtained from request object
==============================================
1)can accept only relative path
2)the path CAN start with or with out "/"
3)the path is considered as relative to the current URL path

1. Can accept relative or absolute path
2. Correct
3. It should depend on whether the path is relative or not

RequestDispatcher obtained from context object
===============================================
1)can accept only relative path
2)the path SHOULD start with "/"
3)the path is considered as relative to the current URL path

The pathname must begin with a "/" ie absolute and is interpreted as relative to the current context root.




Hope this clarifies the thing.

This path must be relative to the root of the ServletContext

Thanks Sarang Bharambe and Gaurav Gambhir...

I agree with Gambhir, the relative path is considered as relative to the context.

Sarang, the path we specify in requestDispatcher is relative path only.

From Spec
==========
The getRequestDispatcher method takes aString argument describing a
path with in thes cope of the ServletContext. <b>This path must be relative</b> to the root of the ServletContext and begin with a �/'.
