how to set header tags color using cookie?

[Punit Jain]

can anyone tell me how can i change color of header tags (ie. h1, h2, h3), i mean accept color from user and maintain that color in cookies and use maintained color from cookie, and set color to header tag..??

Why would you not keep the colors in session, or a backing bean, then render the html or css from them?

at.

I suspect that the OP means for these settings to be kept across sessions.

Seems pretty simple to me. Save the settings in a cookie; look up the cookie; format the CSS as appropriate to the settings.

Let us know when you've got it implemented and any problems you might be having with it.

i m doing it like this:

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		PrintWriter out = response.getWriter();		
		String color = request.getParameter("txt_color");					
		Cookie ck = new Cookie("setColor", color);
		response.addCookie(ck);
		ck.setPath("/");
		ck.setMaxAge(100);
		
		Cookie[] cookies = request.getCookies();
		if(cookies!=null)
		{
			String colorValue = ck.getValue();
			out.println(colorValue);
		}
	}

but how will i set this color as my header tags color although it's a string..??

You're setting the cookie for the response - you can't possibly see it in the request that happened before you created the cookie. On the second access to the servlet you should see the cookie.

but i am able to see the cookie..
i am getting output as the color name.

Now that you know how to get the color from the cookie, next thing you need find out how do you set the color of the header tag. Then worry about putting the color from cookie into the color of header tag.

<h1 color="red"></h1>
this red values i m getting from user, but how do i set??

[Paul Clapham]

How are you generating that tag now?

[Punit Jain]

no but my question is, the values which i am getting from user is string, how do i set that as color??
here is i tried:

String color = request.getParameter("txt_color");
out.println("<h1 color=color>This is h1</h1>");

[Paul Clapham]

Really, this is just beginner Java. Instead of

out.println("<h1 color=color>This is h1</h1>"); 

which just prints out a String literal, you use some code which does String concatenation to produce the desired result:

out.println("<h1 color=" + color + ">This is h1</h1>");
