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" ?>

15.5.2. Running in command-line mode
The command-line application can also be started by an ant target.
$ ant run

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.
