Passing parameters to a servlet from an html link

What is the code to pass a parameter to a servlet from a link in an html page.

Currently I have in my servlet a dynamically created link:

out.println("<ahref= \"http://localhost:80/servlets/sessionservlet?id= " + field0 +"\"> Add item to shopping cart </a><p>");

The 'id=value' is the parameter I would like to pass to the sessionservlet, however when I try to do:

String idbooktoadd = req.getParameter("id")

in the sessionservlet nothing is stored in the string variable 'idbooktoadd'

Please help

Hi help_me,

In HTML usage of double quotes is optional. Try with this code.

>> Your code

out.println("<ahref= \"http://localhost:80/servlets/sessionservlet?id=
                      " + field0 +"\"> Add item to shopping cart </a><p>");


new code

out.println("<a href= http//localhost:80/servlets/sessionservlet?id=
                      " + field0 +"> Add item to shopping cart </a><p>");

Best of luck
