prob.. confirm message

[abhit_kumar]

hey...

its the updation query.In this page when i click the update button it updates the values in the row..and this query is working...

I want to do that..when i click a update button it gives me a confirms message whether did u want to update the row and also displaying the particular gl_code no in that confirms message.when i click on yes it updates the row..otherwise it doesnot.

after updation it shows message that this particular gl_code no is has been updated.

<%
String action = request.getParameter("action");

if (action != null && action.equals("update")) {
conn.setAutoCommit(false);


PreparedStatement pstatement = conn.prepareStatement(
"UPDATE gl_mast SET gl_descr = ?, db_amt = ?, " +
"cr_amt = ?, gl_type = ? , gl_pct = ? WHERE gl_code=?");

pstatement.setString(1, request.getParameter("gl_descr"));
pstatement.setFloat(2,Float.parseFloat(request.getParameter("db_amt")));
pstatement.setFloat(3,Float.parseFloat(request.getParameter("cr_amt")));
pstatement.setString(4, request.getParameter("gl_type"));
pstatement.setFloat(5,Float.parseFloat(request.getParameter("gl_pct")));
pstatement.setInt(6,Integer.parseInt(request.getParameter("gl_code")));

int rowCount = pstatement.executeUpdate();
conn.setAutoCommit(false);
conn.setAutoCommit(true);
}



%>


<%

Statement statement = conn.createStatement();

ResultSet rs = statement.executeQuery
("SELECT * FROM gl_mast ");

%>


<form action="gl_update.jsp" method="get">
<input type="hidden" value="update" name="action">
<tr>
<td><input value="<%= rs.getInt("gl_code") %>" size="5" name="gl_code"></td>

</tr>
</form>

you can use JavaScript for such functionality...the following line
<input type="submit" value="Update">

should be like this

<input type="submit" value="Update" onclick="return confirm('do u really want to submit?');"/>

Now I want to suggest here that you must want to remove your business logic code(database queries) to some hidden part of the application, using db queries in a jsp is probably oneof the worst practices that one can resort to in web programming with java.
