How load servlet on index.jsp

Question

Is there is any way to call a servlet on index.jsp? My welcome file is index.jsp. I need to populate dropdown list values by a servlet when i

Answer 1

Just change the welcome file URL to be the one of the servlet.

Given this servlet mapping,

    indexServlet
    /index

just have this welcome file list:

    index

Don't forget to move the /index.jsp into /WEB-INF folder to prevent it from being accessed directly by endusers guessing its URL (and don't forget to alter the forward call in the index servlet to point to /WEB-INF/index.jsp).

Or if you solely intend to have a "home page servlet" and not an "index servlet", then map the servlet to the empty string URL pattern instead of as welcome file.

    indexServlet
