    A servlet is a web-server side Java component which typically communicates using HTTP. You can use it for executing whatever logic you want at the server side. It can also emit HTML as output to be displayed on the client-side on a browser or something. A JSP is also ultimately compiled into a servlet.

    A bean is just like a data-holder - a wrapper of certain information in an entity with properties which can be read/ written to. For example, a Customer bean can be like:

    public class Customer implements Serializable
      private String ID ;
      private String name ;
      public void setID ( String ID ) // setter for 'ID' property
        this.ID = ID ;
      public String getID () // getter for 'ID' property
        return ID ;
      public void setName ( String name ) // setter for 'name' property
      { = name ;
      public void getName () // getter for 'name' property
        return name ;
