Hello Sir,
I have a simple Issue but It is not resolve by me i.e input parameter
are not store in Ms-Access.
I store the input parameter through Standard Action <jsp:useBean>.
jsp:useBean call a property IssueData. this property exist in
SimpleBean which create a connection from DB and insert the data.

At run time servlet and server also show that loggging are saved in DB.
But when I open the table in Access. Its empty.
Ms-Access have two fields- User, Password both are text type.
Please review these code:
login.html:

<html>
<head>
<title>A simple JSP application</title>
<head>
<body>
<form method="get" action="tmp" >
Name: <input type="text" name="user">
Password: <input type="password" name="pass">
<input type="Submit" value="Submit">
</form>
</body>
</html>

Please Help me..Thanks.!!!

Is the connection in autoCommit mode? If not, then you need to explicitly commit the transaction. Check the return value of the executeUpdate ; is it 1?

Does a standalone program which inserts some sample data in the table works?
