Question

Can you call a servlet with a link? For example

<a href="/servletName">link text</a>

And possibly pass parameters to the request object by adding them to the querystring.

If not, I have seen this kind of thing:

RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(/MyServlet); 
dispatcher.include(request,response); 

But how would I trigger this? For example if it was JavaScript code I could put it within a jQuery click function, or if this was a servlet I would put it into a method.

But how do I call this code from within a JSP. As far as I know you can’t call Java code with JavaScript events.

Answer 1

<a href="servletUrl?param=value">click</a>

is perfectly legal and will work.

That will make the doGet(..) method of the servlet be called, and you can get the parameter using request.getParameter("param")
