Hello jagadish

Correct this line
String query = "select uname from userid where password=pword"; TO
String query = "select uname from userid where password='" + pword +"'";

You not specify which IDE use. if u use eclispe check the file named .classpath in this manner

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="con" path="com.genuitec.eclipse.j2eedt.core.J2EE14_CONTAINER"/>
<classpathentry kind="lib" path="WebRoot/WEB-INF/lib/mysql-connector-java-3.0.16-ga-bin.jar"/>
<classpathentry kind="output" path="WebRoot/WEB-INF/classes"/>
</classpath>

create inside WEB-INF folder lib folder
put the mysql jar file

other wise come online through gtalk

Thanks

Hi ,


<%@ page language="java" import="java.sql.*" import="java.util.*" %>


<%



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

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



Connection con = null;
String url = "jdbc:mysql://192.168.10.211:3306/";;
String db = "amar";
String driver = "com.mysql.jdbc.Driver";
String userName ="amar";
String pass="amar123";

try {

Class.forName(driver);
con = DriverManager.getConnection(url+db,userName,pass);

Statement st = con.createStatement();

String strQuery = "select * from login where userid='"+userid+"' and password='"+password+"'";

out.println(strQuery);

ResultSet rs = st.executeQuery(strQuery);



while(rs.next()){

if((rs.getString(1).equals("admin")) && (rs.getString(2).equals("admin")))

{

session.setAttribute("userid",userid);

response.sendRedirect("userForm.jsp");
}


if((rs.getString(1).equals("user")) && (rs.getString(2).equals("user")))

{

session.setAttribute("userid",userid);

response.sendRedirect("registrationForm.jsp");
}

else{

response.sendRedirect("loginForm.jsp");

}


}

System.out.println("Connected to the database");

con.close();



} catch (Exception e) {

e.printStackTrace();

}
