[mallikarjun dontamsetti]

Hi,
I am designing some sample project which should connect to database, and get data and display it in jsp using JSTL.It is working well The worst part is to edit,view,delete (fields at end of each row) they are links and i have to send it to servlet and get data for particular field and display back in jsp(MVC Archetecture).

Please help me to Redirect the link to Servlet

When i click the link it should redirect to servlet and get data of the row from servlet and display it in JSP

[Vic Hood]

Hi
You could use something like

    <a href="YourJSP .jsp?${id}">Edit </a>   

[mallikarjun dontamsetti]

I want to redirect to servlet

[Vic Hood]

Well you could submit to the same jsp and have a form in the jsp that submits to your servlet?

[mallikarjun dontamsetti]

I am restricted to use any kind of buttons

[Vic Hood]

thats a weird restriction , maybe you try just specifying your servlet instead of the jsp file in my snippet . Not sure though

[mallikarjun dontamsetti]

What is id in your snippet

[Vic Hood]

Id is something i put in for your reference for say you want to uniquely identify a row in your table and then do DB operations with that particular row.

Thanks it is working

How to get the ID in Sevlet

[mallikarjun dontamsetti]

Hy can any one tell me how to get value from id in Servlet

I Used request.getParameter("emp_id");

But it's prints null value and i used

<input type="hidden" name="emp_id"value="${emp.emp_id}"/>

It is also showing null value.
Please Help me Please Urgent

You should use the url tag in JSTL core library to create your URLs. It should look something like the following

<c:url value="Servlet_URL_Mapping">
    <c:param name="empId" value="${emp.emp_id}"/>
    <c:param name="action" value="EDIT"/>
</c:url>

This will send a request to the Servlet specified by the URL in the value attribute with two request parameters named empId and action.
