The MySQL JDBC driver (since SchemaExport executes JDBC statements, it needs the driver). You will very likely need to modify B above to make the mysql.version and jdbc.driver.jar properties match your configuration. The hibernate.cfg.xml and the hbm.xml files, including Event. hbm.xml and Location.hbm.xml files. For the sake of simplicity, we are storing the mapping files alongside their corresponding Java source files; this is why we add the ${src.java.dir} directory to the runtime classpath. The log4j.properties file (we haven t covered it yet, but it needs to be at the root of the classpath, right next to hibernate.cfg.xml).4 Also note that you are using a new Ant task, called taskdef, which allows you to define new tasks that you can invoke later in the Ant file. Here you define a new task, SchemaExport, and link it to the actual SchemaExportTask. You also use the runtime.classpath you defined earlier.

Finally, the SchemaExport task needs a few configuration details, such as which database to run against and the user/password information. You have already provided this information in the hibernate.cfg.xml file, and SchemaExport can use it if you provide its location. With all this in place, you should be able to run the SchemaExport task and build the database. And you can but there is one more piece that you should configure first: Hibernate s logging framework.

Hibernate uses a logging framework, which can help new developers figure out just what it s doing under the covers. It uses the Apache Commons Logging framework, which is a simple API that allows users to substitute different logging implementations without recompiling. Developers can use the Java 1.4 java.util.logging framework or the

popular open source log4j framework. So, just as JDBC is a databaseneutral API that abstracts away the specific data, Commons Logging is a logging-neutral API. By default, Hibernate is set up to use log4j, so the path of least resistance is to use that. Hibernate will work just fine without configuring logging, but it will nag you about it. So when you run the SchemaExport task, you will see something like this:

By putting a log4j.properties file into the root of the classpath, you stop the nagging and obtain information about Hibernate s internal steps. Use your text editor to create a new file called log4j.properties (listing 4.8) in the /work/calendar/src/java directory.

### direct log messages to stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %5p %c{1}:%m%n ### set log levels - for more verbose logging change ### 'info' to 'debug' log4j.rootLogger=warn, stdout log4j.logger.org.hibernate=warn
The purpose of the logging file is to specify three main things:
How much information to log, and how noisy the output is (via log levels)
Associations and components
Where that information goes (via appenders) How the information is formatted (via patterns) This listing includes a single appender, called stdout, which sends all of the output to the command line. It configures the global root logger (log4j.rootLogger) to log at the warn level. warn is medium noisy, debug is extremely detailed, and fatal will stay quiet unless something goes seriously wrong. In addition to the global logging, you can configure it on a per-package level, if you only want the gritty details from one particular package. You did so above, using log4j.logger.org.hibernate=warn. This is the package where all the Hibernate classes live. It allows you to set them to their loggers individually; for example, you can set them to debug but leave the root logger at warn.
Hibernate also comes with a more detailed log4j.properties file, which this one is based on. It contains a few more in-depth examples. Look in the /applications/hibernate-3.0/src for it. You should also visit the log4j and Commons Logging homepages, which can be found at http://logging.apache.org/log4j/docs and http://jakarta.apache.org/commons/logging, respectively, for more information and complete documentation for both of these projects. Now, with this final piece in place, you can go ahead and build the tables.
