Hi guys,

How can i use an HTTPServletRequest on a class?
I want to get the httpheader of a page.

Thanks

Here's a helpful tip: Be sure to take the time to compose descriptive subjects for your posts; read this for more information.

A title such as "HTTPServletRequest" is not helpful. What would happen if all posts had such a title?

The interface name is HttpServletRequest. Case counts!

An implementation of this interface is passed to the servlet's doPost() and doGet() methods when a servlet is invoked. Methods on this interface allow you to retrieve request headers.

[michael ancheta]

Ok. Thanks for that.

this would work right?
I just need to import the necessary servlet classes.

Enumeration enumeration = request.getHeaderNames();
    while (enumeration.hasMoreElements()) {
	String string = (String)enumeration.nextElement();
	out.println(request.getHeader(string));
        
    }

Another tip: Be sure to use code tags when posting code to the forums. Unformatted code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please read this for more information.

What happened when you tried it?

[michael ancheta]

I dont know if its returning the correct value.
What does this method do?
What is it returning?

request.getHeaderNames();

i want to use the method

getHeaderNames()

from the HttpServletRequest interface.

but i think i did right. just want a verification.

It returns an enumeration of the HTTP header names in the request, as described in its javadocs.

Is it returning the names of the headers in your request? You can use a tool like Firebug or any general network sniffer to check what's coming across "on the wire".
