[Madhuri Abhi]

Hi all,

can i get ahref id value from jsp to a servlet?? Is so, is the following code correct???

 
***** JSP Code****** 

<a href="/image/loadServlet"?id="name"></a>

I would assume that you get the value 'name'. What happens when you try it?

Yes, you can get the value as below. But it is not good practice to hardcode the values in the URL.

Raj,

There is no error but nothing is shown in the page.

Santosh,

What i am actually doing is displaying the values in jsp page(in a table) from database. and when one of those fields is clicked, corresponding value should be shown.

To make it more clear, say suppose i have id(varchar), name(varchar) and content(blob) fileds in database. I get id and name in jsp page and display it in a table. when i click on the name, it redirects to a servlet thereby corresponding content should be displayed.

For this, i need to know which name he has clicked.

**** JSP Page(Not posting the full code)*****

<% while(rs.next()){
    %>
   
    <tr BGCOLOR="#DDF1F9">
    <td width="168"><%out.println(rs.getString("id"));%></td>
    <td width="200"><%out.println(rs.getString("date"));%></td>
    <td width="168"><a href="/imageAndDoc/downloadFileServlet"?id=<%out.println(rs.getString("name"));%>><%out.println(rs.getString("name"));%></a></td> 
  <td width="168"><%out.println(rs.getString("type"));%></td>
    <td width="168"><%out.println(rs.getString("quarter"));%></td>
    </tr>
<%}%>

*********Servlet Page****

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

What i actually do in the below code is that i display the name field from database. and so when i click on any of the names in the jsp page, corresponding content should be shown.

<td width="168"><a href="/imageAndDoc/downloadFileServlet"?id=<%out.println(rs.getString("name"));%>><%out.println(rs.getString("name"));%></a></td>

Then how to pass that id, please tell me if any methode is there thanks

You could use the parameter as a FORM field (hidden-field) if necessary. I do not see any issues with passing a parameter as part of the query string parameter. Parameters in GET requests go that way anyways.

Hi Madhuri,

I am also working on exactly same requirement and stuck. Could you please let me know how did you resolved your issue.

Please message me the sample code.

Don't use java code inside jsp, its a very old practice. Look for JSTL,EL etc. You can pass any dynamic value in query string.
<c:set var="idval" value="10"/>
<a href=myservlet?id=<c:out value="${idval}"/>>
