Hi Friend,

If you want to call servlet from another jsp i.e 'main.jsp', then you have to store the value of id in main.jsp using the following:

<input type="hidden" name="idvalue" value="<%=id%>">

In servlet, use the following code to retrieve value of id:

String id=request.getParameter("idvalue");

Hope that it will be helpful.

Thanks
