How to call doPost() servlet from a hyperlink in jsp
Question
How can I call a servlet from jsp ? But in this case, I prefer to use doPost() method than doGet() .
this is my code:
view.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" import="DSIP.*" import="java.util.ArrayList" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>DSIP.View</title>
</head>
<body>
<jsp:useBean id="ipList" scope="application" class="DSIP.IPBeanMapper"/>
<jsp:useBean id="bean" scope="application" class="DSIP.IPBean"/>
<form name="form1" method="post" action="viewS">
<table width="" border="">
<tr bgcolor="#0099FF">
<td width="90"><div align="center">ip</div></td>
<td width="90"><div align="center">username</div></td>
<td width="90"><div align="center">password</div></td>
<td width="90"><div align="center">maxRetry</div></td>
<td width="90"><div align="center">action</div></td>
</tr>
<%
ArrayList<IPBean> list;
list = ipList.getIPList();
for (int i = 0; i < list.size(); i++){
bean = list.get(i);
%>
<tr>
<td><input name="ip" type="text" size="15" value="<%=list.get(i).getIp()%>"></td>
<td><input name="userName" type="text" size="15" value="<%=bean.getUserName()%>"></td>
<td><input name="password" type="text" size="15" value="<%=bean.getPassword()%>"></td>
<td><input name="maxRetry" type="text" size="15" value="<%=bean.getMaxRetry()%>"></td>
<td><a href="/ViewS?action=edit">edit</a> <a href="/ViewS?action=delete">delete</a>
</td>
</tr>
<%
}
%>
</table>
<input type="submit" name="Submit" value="Submit">
</form>
</body>
</html>
I intend to call a servlet class (called ViewS ) from this page using link (edit n delete). I want to make some filed in a specific row being editable when I click edit and store the values into a database.
and, I want to delete the record in database also record view in jsp when I cleck delete.
So please, somebody help me.
I've tried to use <a href="/ViewS?action=edit">edit</a> , but I know this call doGet() .
Thank you very much for helping me.

You need to call a javascript function on click of link and from javascript you need to submit the form that will generate a HTTP POST
function submitMyForm(){
document.forms["yourFormId"].submit();
}
Or you could make a AJAX call to your servlet

AJAX will be the best option for you. Make an AJAX call from the onClick() method of the <a>
