Chapter 5. Configuring Hibernate for JBoss Web Server

Procedure

1. Get the Hibernate JAR files from the JBoss Web Server Maven Repository.
2. Add the Hibernate JAR files to your deployment WAR file.

Procedure

1. Open the /META-INF/context.xml file.

2. Modify the JDBC connection pools that are available to applications.

   For example:

   <Context>
     <Resource
       name="jdbc/DsWebAppDB"
       auth="Container"
       type="javax.sql.DataSource"
       username="sa"
       password=""
       driverClassName="org.h2.Driver"
       url="jdbc:h2:mem:target/test/db/h2/hibernate"
       maxActive="8"
       maxIdle="4"/>
   </Context>

Procedure

1. Open the /WEB-INF/classes/META-INF/persistence.xml file.

2. Configure Hibernate to consume connections from Tomcat.

   For example:

   <persistence version="1.0"
     xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
   
     <persistence-unit name="dswebapp">
       <provider>org.hibernate.ejb.HibernatePersistence</provider>
       <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
         <property name="hibernate.connection.datasource" value="java:comp/env/jdbc/DsWebAppDB"/>
       </properties>
     </persistence-unit>
   </persistence>

Procedure

1. Open the /WEB-INF/web.xml file.

2. Configure JDBC datasources with the resource-env-ref element.

   For example:

   <?xml version="1.0" encoding="UTF-8"?>
   <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
   
    <resource-env-ref>
     <resource-env-ref-name>jdbc/DsWebAppDB</resource-env-ref-name>
     <resource-env-ref-type>javax.sql.DataSource</resource-env-ref-type>
    </resource-env-ref>
   </web-app>

   The preceding example uses a a jdbc/DsWebAppDB data source.
