    Iam new to jsp and trying to make connection with database in jsp iam using the following code :

    String firstName = request.getParameter("txtName");
    String lastName = request.getParameter("txtLastName");
    String gender = request.getParameter("listGender");
    String address = request.getParameter("txtAdd");
    String country = request.getParameter("txtCountry");

    String email = request.getParameter("txtEmailID");
    String userName = request.getParameter("txtUname");
    String password = request.getParameter("txtPass");
    Connection con =null;
    try {
    	//Driver Loading
    	Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //Or any other driver
    	//Defie the connection URL
    	String url = "jdbc:odbc:cmobs";
    	//Establish the connection
    	con = DriverManager.getConnection(url);
    	//create the statement
    	Statement st = con.createStatement();
    	//Step 6: Execute the query
    	String sql = "insert into Info(FIRSTNAME,LASTNAME,GENDER,DOB,COUNTRY,ADDRESS,,CONTACT,EMAIL,USERNAME,PASSWORD) VALUES('"+firstName+"','"+lastName+"','"+gender+"','"+country+"','"+address+"','"+email+"','"+userName+"','"+password+"')";

    yah i got ur problem...in jsp u have to use "PreparedStatement" alwayz instead of only "statement"..i m sending u a sample program..try to understand this...

    one more thing..before understanding the above code make sure that u know about the "Statement", "PreparedStatement" i.e u shud have complete knowledge about JDBC

    this thread should appear in jsp forum.

    One cause that I think might be that the code is unable to make the connection to the database and going into catch block, and you are giving the command to close the connection.

    Do this:
    make the if condition before closing the database connection, that only if the connection is open close the con.

    If the problem was this, the error should not be on line 43.

    actually i din go with the error i simply had gone with the concept...as far as i know only "PreparedStatement" is used in case of JSP... "Statement" wont work for insert,update and delete...yah u can use only "Statement" for select statement....

    did u set the write environment , cuz its realy important , there are things to get the connection right from what ever database you use , u need to set the nessasary path in you system inevironment , and u may need a JDBC files to get you connection done , + you need the drivers for JDBC to connect .

    i advice you to use JDeveloper for orcel it helps , oh i forgot to say u need to create a class , and one more thing u need to set the write libraries like J2EE , JSP Runtime , and SQLDriver for connections

    hope this helps

    regards alssadi
