always try avoid scriplet instead use javaserver pages standard tag library , expression language more easy use , less error prone.

sql tag library designed accessing databases quick prototyping , simple applications.

sample code:

<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql"%> ...  <sql:setdatasource var="webappdatasource" driver="com.mysql.jdbc.driver"     url="jdbc:mysql://localhost:3306/webapp?user=root&useunicode=true&characterencoding=big5"     user="root" password="" />  <sql:query datasource="${webappdatasource}"              sql="select id, no, name, class, test" var="result" />  <table width="100%" border="1">     <c:foreach var="row" items="${result.rows}">         <tr>             <td>${row.no}</td>             <td>${row.id}</td>             <td>${row.no}</td>             <td>${row.name}</td>             <td>${row.class}</td>             <td><input type='button' name='edit' value='edit' onclick='editrecord(${row.no})' /></td>         </tr>     </c:foreach> </table>

you can try window open() method instead of form submit it's simple request , value passed query string in url.

for e.g.

<input type='button' name='edit' value='edit' onclick='window.open("edit_delete.jsp?id=${row.no}");'/>
