Question

I have two JSP pages that can access a Servlet. Now, I want when JSP 1 access the Servlet, Servlet will do some one kind of job (for example increment an int) and when JSP 2 will access the Servlet, it will do some other kind of job (for example decrement an int).

Can anybody help me by specifying how is it possible ?

Answer 1

You could pass different value on same parameter.

In page1.jsp

<jsp:forward page="/MyServelt">
   <jsp:param name="action" value="incr" /> 
</jsp:forward/>

In page2.jsp

<jsp:forward page="/MyServelt">
   <jsp:param name="action" value="decr" /> 
</jsp:forward/>

If <form> tag is used then add <input type="hidden"/>,

<form method="post" action="/MyServlet">
  <input type="hidden" name="action" value="incr"/>
  .....
</form>
