greeter: Native Hibernate (No JPA)

This application is based on WildFly 10 Quickstart Greeter https://github.com/wildfly/quickstart/tree/10.x/greeter

Native hibernate is used instead of JPA. Note that JPA annotations are used for mapping of User entity.

Changes made

• Removed all two UserDao implementations
• Created new UserDao implementation that uses native Hibernate approach
• Altered UserDao.java interface so that createUser returns User object instead of null
  • this is required to display user ID properly
• Altered CreateController.java so that newly created user object contains ID
• Created new HibernateUtil.java class for Hibernate's sessionFactory creation in native way
  • also table USERS is created and initialized here
• Removed JPA stuff
  • persistence.xml
  • EntityManager setup from Resources.java
• Created jboss-deployment-structure.xml to use WildFly's org.hibernate module
• Added hibernate-core & javassist dependencies to pom.xml
• Used WildFly 10.0.0.CR3 BOMs in pom.xml and used Maven Central only
• Changed name to hibernate-greeter in pom.xml
• Removed import.sql because you can't use hbm2ddl if using native Hibernate with container managed transactions (JTA)
• Updated README.md file :)

greeter: Demonstrates CDI, JPA, JTA, EJB, and JSF

Author: Pete Muir
Level: Beginner
Technologies: CDI, JSF, JPA, EJB, JTA
Summary: The greeter quickstart demonstrates the use of CDI, JPA, JTA, EJB and JSF in WildFly.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/

What is it?

The greeter quickstart demonstrates the use of CDI, JPA, JTA, EJB and JSF in Red Hat JBoss Enterprise Application Platform.

When you deploy this example, two users are automatically created for you: emuster and jdoe. This data is located in the src/main/resources/import.sql file.

To test this example:

1. Enter a name in the username field and click on Greet!.
2. If you enter a username that is not in the database, you get a message No such user exists!.
3. If you enter a valid username, you get a message "Hello, " followed by the user's first and last name.
4. To create a new user, click the Add a new user link. Enter the username, first name, and last name and then click Add User. The user is added and a message displays the new user id number.
5. Click on the Greet a user! link to return to the Greet! page.

Note: This quickstart uses the H2 database included with Red Hat JBoss Enterprise Application Platform 7. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable, is not supported, and should NOT be used in a production environment!

Note: This quickstart uses a *-ds.xml datasource configuration file for convenience and ease of database configuration. These files are deprecated in WildFly and should not be used in a production environment. Instead, you should configure the datasource using the Management CLI or Management Console. Datasource configuration is documented in the Administration and Configuration Guide for Red Hat JBoss Enterprise Application Platform.

System requirements

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7 or later.

All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.1.1 or later. See Configure Maven for WildFly 7 to make sure you are configured correctly for testing the quickstarts.

Use of WILDFLY_HOME

In the following instructions, replace WILDFLY_HOME with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.

Start the WildFly Server

1. Open a command prompt and navigate to the root of the WildFly directory.

2. The following shows the command line to start the server:

    For Linux:   WILDFLY_HOME/bin/standalone.sh
    For Windows: WILDFLY_HOME\bin\standalone.bat
   

Build and Deploy the Quickstart

1. Make sure you have started the WildFly server as described above.

2. Open a command prompt and navigate to the root directory of this quickstart.

3. Type this command to build and deploy the archive:

    mvn clean install wildfly:deploy
   

4. This will deploy target/wildfly-greeter.war to the running instance of the server.

Access the application

The application will be running at the following URL: http://localhost:8080/jboss-greeter.

Undeploy the Archive

1. Make sure you have started the WildFly server as described above.

2. Open a command prompt and navigate to the root directory of this quickstart.

3. When you are finished testing, type this command to undeploy the archive:

    mvn wildfly:undeploy
   

Server Log: Expected warnings and errors

Note: You will see the following warnings in the server log. You can ignore these warnings.

WFLYJCA0091: -ds.xml file deployments are deprecated. Support may be removed in a future version.

HHH000431: Unable to determine H2 database version, certain features may not work

Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

Debug the Application

If you want to debug the source code of any library in the project, run the following command to pull the source into your local repository. The IDE should then detect it.

    mvn dependency:sources
