catching servlet o/p

[Sachin Deshpande]

I have a servlet A which calls another servlet B. B throws an html o/p. how can servlet A catch the o/p sent by servlet B?

Hi
U will have to use the RequestDispatcher's include(req,res) method in the calling servlet(servlet A in ur case) which then will include the output of the called servlet(servlet B in ur case) at the point of inclusion!!
Only thing that u have to keep in mind that u should use version2.1 and later (since RequestDispatcher got introduced in 2.1 only) for ur servlet class files to compile successfully
Kindly keep me informed if this explanation helped u sort out ur problem!!
Wish u all the best

Do I have to add data(or an object) that i want to pass in the req obj?
and then do i just call B by the sendRedirect method as I have been doing???

Sachin,
A sample code in your calling sevlet which is 'Servlet A' could be

RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(response.encodeURL("/servlet/B_ServletName"));        
dispatcher.include(request,response);

}
catch(Exception e)
