    Where should I write the JDBC code

    If we have 10 servlets, and we need to use database connection. Then Where should I write the JDBC code that must be established from a servlet and need to utilize in all other servlets

    You can create a Connection Class, keep one getConnection method there which has JDBC code and
    whenever u want to create a connection then make object of that class
    and call that function.

    If you are going for big projects then you can use connection pooling!

    thanks

    Write a separate java class with the static getConn() method. u can get the connection object by Connection con = MyConnection.getConn()
    or
    use context param in deployment descriptor file(web.xml) outside all servlet tags add the details about ur database later get the parameter values in init() using getInitParameter()
    here is the sample code

    url
    sun.jdbc.odbc.JdbcOdbcDriver
    connstring
    jdbcdbc:mydsn

    Do one thing write a simple java class and put all the JDBC code and use the class in servlets where u want.
    if you are using the application Servler better to use the Connection Pooling which ipmroves the performance of the application.
    It may helps you..
    Thanks..
