These are the details I followed for making a servlet with Hibernate. This will take off from the last post with Many to Many<\/a>. It is a rehash from the original Hibernate documentation.\u00a0 Make sure that you have .m2\/settings.xml so that it has the jboss repository. See my Hibernate Tutorial Refined<\/a> for details. For this tutorial. You will also need Tomcat<\/a>. Download it. Unzip it somewhere else on your system.<\/p>\n

Start this tutorial by downloading the base code and unzip it. The ‘$’ indicates the command prompt. Don’t type it. I assume you are using GNU\/Linux for this tutorial. It will work on Windows too with minor modification.<\/p>\n


\n<\/code>$ wget http:\/\/brie.com\/brian\/hibernate\/servlet\/hib-serve.zip
\n$ unzip hib-serve.zip
\n$ cd hib-serve<\/code><\/p>\n

Make sure that you are in the directory that contains the pom.xml<\/em> file. Start the HSQLDB database as a server (all on one line):<\/p>\n

$ mvn exec:java -Dexec.mainClass=\"org.hsqldb.Server\" -Dexec.args=\"-database.0 file:target\/data\/tutorial\"<\/code><\/p>\n

Open a separate command prompt window and start the Database Manager (all on one line). Make sure that you are in the directory with the pom.xml <\/em>file.<\/p>\n

$ mvn exec:java -Dexec.mainClass=\"org.hsqldb.util.DatabaseManagerSwing\" -Dexec.args=\"-url jdbc:hsqldb:hsql:\/\/localhost\/ -driver org.hsqldb.jdbcDriver\"<\/code><\/p>\n

Make the directory for the Servlet configuration. Download the configuration file and move it to the correct place. Basically, this configures the url that maps to the servlet class.<\/p>\n

$ mkdir -p .\/src\/main\/webapp\/WEB-INF
\n$ wget http:\/\/brie.com\/brian\/hibernate\/servlet\/web.xml
\n$ mv web.xml .\/src\/main\/webapp\/WEB-INF<\/code><\/p>\n

The following is the code for the Servlet. Download it, copy it to the correct place.<\/p>\n

$ wget http:\/\/brie.com\/brian\/hibernate\/servle\/EventManagerServlet.java
\n$ mv EventManagerServlet.java src\/main\/java\/org\/hibernat\/tutorial\/web\/<\/code><\/p>\n

The EventManager had all private methods. Replace it with one that has public methods that can be used by the Servlet.<\/p>\n

$ wget http:\/\/brie.com\/brian\/hibernate\/servlet\/EventManager.java
\n$ mv EventManager.java src\/main\/java\/org\/hibernate\/tutorial\/<\/code><\/p>\n

Compile the project using the following Maven command:<\/p>\n

$ mvn compile<\/code><\/p>\n

This example uses the hbm2ddl.auto property, so it will automatically create the schema when the program is run. Now add a person to the event using the Event manager from the command line with the following command (all on one line):<\/p>\n

$ mvn exec:java -Dexec.mainClass=\"org.hibernate.tutorial.EventManager\" -Dexec.args=\"addpersontoevent\"<\/code><\/p>\n

Check the database manager. You should see an event. Now, create a war file using the following command. It will create a hib-create.war file in the target subdirectory.<\/p>\n

$ mvn package<\/code><\/p>\n

Now copy the hib-create.war to your Tomcat webapps directory. Replace <Tomcat-home> <\/em>with where you unziped Tomcat.<\/p>\n

$ cd target
\n$ cp hib-create.war <Tomcat-home>\/webapps
\n<\/code><\/p>\n

Start Tomcat.
\n$ cd
\n$ bin\/startup.sh<\/code><\/p>\n

Tomcat should start. Go to your browser, and you should be able to access the servlet and enter an event.<\/p>\n

http:\/\/localhost:8080\/hib-serve\/eventmanager<\/em><\/p>\n

Add an event and you are good to go. This concludes the simple creation of a servlet with Hibernate and Maven.
