15.5 Putting Things Together

The project can be compiled by ant (http://jakarta.apache.org), it but must be modified slightly to use other JDO implementations . A build.xml file can be found in the top-level directory.

15.5.1 XML metadata

The model.jdo metadata file is located in the src/com/corejdo/casestudy directory and follows the JDO 1.0 naming convention.

 <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE jdo PUBLIC "-//Sun Microsystems, Inc.//DTD Java Data Objects Metadata 1.0//EN" "http://java.sun.com/dtd/jdo_1_0.dtd"> <jdo>     <package name="com.corejdo.casestudy.model">       <class name="Book">       </class>       <class name="CD">       </class>       <class name="Copy">       </class>       <class name="Library">       </class>       <class name="Publication">       </class>       <class name="Rights">       </class>       <class name="Song">       </class>       <class name="User">       </class>     </package> </jdo> 

15.5.2 Running in command-line mode

The command-line application can also be started by an ant target.

 $ ant run Use case [ListBooks]:   Type name of use case here!   Start at [0]: Count [10]: Result: 1: Title:  Travel Guide: Sweden    Author: Joseph, Bert    ISBN:   7-7333-4727-6    (C):    O'Renny ... 

The datastore can be filled with random data by the FillDatabase command. For some operations, you have to log in. The initial user name is "su," and the password is "su." Here is how to add new users:

 Use case [ListBooks]:  Login  UserId []:  su  Password []:  su  Use case [Login]:  EditUser  Find User Id [hb]:  smith  User not found. Add [false]:  true  First name:  John  Last name:  Smith  Password:  js  May borrow [false]:  true  May manage publications [false]:  true  May manage users [false]:  true  Use case [EditUser]: _ 

15.5.3 Running the Servlets

Figure 15-4: A running Servlet shows a screenshot of a Web page that is generated from the ListBooks.jsp code. Again, ant can be used to start the tomcat Web server. The pages are compiled on demand. Please make sure that the Java SDK is set in the classpath ; it is needed by the tomcat JSP engine.

$ ant servlet starts the server.
