How to Connect Servlet to the Database with Example

Servlets » On Feb 7, 2013 { 14 Comments } By Sivateja

Let us see how to connect servelet application with (Oracle) database, for time being i am considering Oracle XE.  In our application i am going to display all the records from the table ‘Java4s‘.

  • Make sure you have java4s table in the database with some data in it
  • Make sure you have ojdbc14.jar file in your classpath and lib folder as well as [ why in two places ? :-) servlet will use ojdbc14.jar file which is in the classpath, for compiling the application, and ojdbc14.jar file in lib folder will be used at the time of running the servlet application], you can check the same in this figure…

Directory Structure

Files Required

  • index.html
  • web.xml
  • ojdbc14.jar

    Making connection SQL server Database

    Using the sqljdbc.jar class library, applications must first register the driver as follows:


    When the driver is loaded, you can establish a connection by using a connection URL and the getConnection method of the DriverManager class:

    String connectionUrl = “jdbc:sqlserver://localhost:1433;” +
    Connection con = DriverManager.getConnection(connectionUrl);
