JBoss AS Quickstarts

[TOC]

Introduction

The quickstarts included in this distribution were written to demonstrate Java EE 6 and a few additional technologies. They provide small, specific, working examples that can used as a reference for your own project.

These quickstarts will run in both the JBoss AS 7 or the JBoss Enterprise Application Platform 6 environments. If you want to run the quickstarts in JBoss Enterprise Application Platform 6, we recommend using the JBoss Enterprise Application Platform zip file. This version uses the correct dependencies and ensures you test and compile against your runtime environment.

Be sure to read this entire document before you attempt to work with the quickstarts. It contains the following information:

• Available Quickstarts: List of the available quickstarts and details about each one.

• System Requirements: List of software required to run the quickstarts.

• Configure Maven: Configure the Maven repository for use by the quickstarts.

• Build and Deploy the Quickstarts: General instructions for building and deploying the quickstarts.

• Suggested Approach to the Quickstarts: Suggested Approach on how to start with the quickstarts.

• Optional Components: Install and configure optional components for the quickstarts that need it.

Suggested Approach to the Quickstarts

We suggest you approach the quickstarts as follows

• Regardless of your level of expertise, we suggest you start with the helloworld example. It is the simplest example and is an easy way to prove your server is configured and start correctly.
• If you are a beginner or new to JBoss, start with the quickstarts labeled Beginner, then try those marked as Intermediate. When you're comfortable with those, move on to the Advanced.
• Some quickstarts are based on other quickstarts, but have expanded capabilities and functionality. If a prerequisite quickstart is listed, be sure to run through it before looking at the expanded version.

System Requirements

To run these quickstarts with the provided build scripts, you will need the following:

1. Java 1.6, to run JBoss AS and Maven. You can choose from the following: * OpenJDK * Oracle Java SE * Oracle JRockit

2. Maven 3.0.0 or newer, to build and deploy the examples * Follow the official Maven installation guide if you don't already have Maven 3 installed. * If you have Maven installed, you can check the version by running this command in a command line:

          mvn --version 
   

3. The JBoss AS 7 distribution zip or the JBoss Enterprise Application Platform 6 distribution zip * For information on how to install and run JBoss, refer to the product documentation.

4. You can also deploy the quickstarts from Eclipse using JBoss tools. For more information on how to set up Maven and the JBoss tools, refer to the Getting Started Developing Applications Guide.

Configure Maven

Maven configuration is dependent on whether you are running JBoss AS7 or JBoss Enterprise Application Platform 6.

Configure Maven for JBoss AS

If you are using the JBoss AS 7 Quickstart distribution, the community artifacts are available in the Maven central repository so no additional configuration is needed.

Configure Maven for JBoss Enterprise Application Platform 6

If you are using the JBoss Enterprise Application Platform 6 distribution, you will need to download and configure the Maven repository.

1. Download the JBoss Enterprise Application Platform 6 Maven repository distribution zip and unzip it into a directory of your choice.

2. Modify the example-settings.xml file located in the root of your quickstarts folder. Replace all instances of path/to/jboss-eap/repo within file:///path/to/jboss-eap/repo with the fully qualified path to the Maven repository you unzipped in the previous step.

3. When you run Maven commands, you will need to append -s _PathToQuickstarts_/example-settings.xml to the command, for example:

          mvn jboss-as:deploy -s _PathToQuickstarts_/example-settings.xml
   

4. You can configure the Maven user settings if you do not want to add the alternate path parameter each time you issue a Maven command. * If you have an existing ~/.m2/settings.xml file, modify it with the configuration information from the example-settings.xml file. * If there is no ~/.m2/settings.xml file, copy the example-settings.xml file to the ~/.m2 directory and rename it to settings.xml.

Build and Deploy the Quickstarts

To run the quickstarts, in most cases you do the following:

1. Start the JBoss application server.

a.   Open a command line and navigate to the root of the JBoss directory.

b.   For most of the quickstarts, you run the standalone script located in the JBoss server /bin/ folder with no arguments. The following shows the command line to start the JBoss AS 7 or Enterprise Application Platform 6 Server.

| **Operating System** | **Command Line to Start the Server** |
|:-----------|:-----------|
| Linux | JBOSS_HOME/bin/standalone.sh |
| Windows | JBOSS_HOMEHOME\bin\standalone.bat |

c.  Some quickstarts use subsystems or services included only in the full profile. 
    *  By default, the JBoss Enterprise Application Platform 6 standalone configuration contains the full profile, so you start the server with the same command line as above. No argument is required. 
    *  However, in JBoss AS 7, the default configuration defines minimal subsystems and services, so you need to add a parameter to the command line when you start the server. 
    *  The following shows the command line to start JBoss AS 7 with the full profile.

    | **Operating System** | **Command Line to Start the Server with a Full Profile** |
    |:-----------|:-----------|
    | Linux | JBOSS_HOME/bin/standalone.sh  -c standalone-full.xml |
    | Windows | JBOSS_HOMEHOME\bin\standalone.bat -c standalone-full.xml |

d.  Some quickstarts require custom configuration and require command line arguments. If a command line argument is required, the quickstart README will provide specific instructions.

2. Build and deploy the quickstarts * Open a command line and navigate to the root of the directory of the quickstart you want to run. * Build the archive

   • The command used to build the quickstart will depend on the individual quickstart, the server version, and how you configured Maven.
   • If you are running JBoss AS 7, it uses community artifacts available in the Maven central repository, so command line arguments are not usually required.
   • If you are running JBoss Enterprise Application Platform 6 and did not configure the Maven user settings described in in step 4 in
     Maven Configuration for JBoss Enterprise Application Platform 6
     above, you will need to specify command line arguments.
   • Although some of the quickstarts require special commands, for most of the quickstarts you will do the following.

   Server Version	Command to Build the Quickstart
   JBoss AS 7	mvn clean package
   JBoss Enterprise Application Platform 6, Maven user settings configured	mvn clean package
   JBoss Enterprise Application Platform 6, Maven user settings NOT configured	mvn clean package -s PathToQuickstarts/example-settings.xml

*   Deploy the archive built in the previous step by typing the following in the command line:

            mvn jboss-as:deploy

*   Build and deploy the quickstart in one step
    *  The command you issue to build and deploy the quickstart also depend on the individual quickstart, the server version, and how you configured Maven. 
    *  As mentioned above, if you are running JBoss Enterprise Application Platform 6 and did not configure the Maven user settings described in in step 4 of [Maven Configuration for JBoss Enterprise Application Platform 6](#eap6mavenconfig) above, you will need to specify command line arguments. 
    * Although some of the quickstarts require special commands, for most of the quickstarts you will do the following.

    | **Server Version** | **Command to Build and Deploy the Quickstart** |
    |:-----------|:-----------|
    | JBoss AS 7 | mvn package jboss-as:deploy |
    | JBoss Enterprise Application Platform 6, Maven user settings configured | mvn package jboss-as:deploy |
    | JBoss Enterprise Application Platform 6, Maven user settings NOT configured | mvn package jboss-as:deploy -s _PathToQuickstarts_/example-settings.xml |

*   The command to undeploy the quickstart is simply: 

            mvn jboss-as:undeploy

3. See the README file in the individual quickstart folder for specific details and information on how to run and access the example.
4. You can also start JBoss AS 7 and deploy the quickstarts using Eclipse. See the Getting Started Developing Applications Guide for more information.

Optional Components

The following components are needed for only a small subset of the quickstarts. Do not install or configure them unless the quickstart requires it.

Install and Configure the PostgreSQL Database <aid="postgresql"/>

Some of the quickstarts require the PostgreSQL database. This section describes how to install and configure the database for use with the quickstarts.

Download and install PostgreSQL 9.1.2

The following is a brief overview of how to install PostgreSQL. More detailed instructions for installing and starting PostgreSQL can be easily found on the internet.

Linux Platorm instructions

Use the following steps to install and configure PostgreSQL on Linux. You can download the PDF installation guide here: http://yum.postgresql.org/files/PostgreSQL-RPM-Installation-PGDG.pdf

1. Install PostgreSQL

• The yum install instructions for PostgreSQL can be found here: http://yum.postgresql.org/howtoyum.php/

• Download the repository RPM from here: http://yum.postgresql.org/repopackages.php/

• To install PostgreSQL, in a command line type:

  * `sudo rpm -ivh pgdg-fedora91-9.1-4.noarch.rpm`
  

• Edit your distributions package manager definitions to exclude PostgreSQL. See the "important note" on http://yum.postgresql.org/howtoyum.php/ for details on how to exclude postgresql packages from the repository of the distribution.

• Install postgresql91 and postgres91-server by typing the following in a command line:

  * `sudo yum install postgresql91 postgresql91-server`
  

2. Set a password for the postgres user

• In a command line, login as root and set the postgres password by typing the following commands:

  * `su`
  * `passwd postgres`
  

• Choose a password

3. Configure the test database

• In a command line, login as the postgres user, navigate to the postgres directory, and initialize the database by typing:

  * `su postgres`
  * `cd /usr/pgsql-9.1/bin/`
  * `./initdb -D /var/lib/pgsql/9.1/data`
  

• Modify the /var/lib/pgsql/9.1/data/pg_hba.conf file to set the authentication scheme to password for tcp connections. Modify the line following the IPv4 local connections: change trust to to password. The line should look like this;

          host    all    all    127.0.0.1/32    password
  

• Mofify the /var/lib/pgsql/9.1/data/postgresql.conf file to allow prepared transactions and reduce the maximum number of connections.

          max_prepared_transactions = 10
          max_connections = 10
  

3. Start the database server.

• In the same command line, type the following:

  • ./postgres -D /var/lib/pgsql/9.1/data

• Note, this command will not release the command line. In the next step you weill new to open a new command line.

4. Create the test1 database

• Open a new command line and login again as the postgres user, navigate to the postgres directory, and create the test1 database by typing the following:

  * `su postgres`
  * `cd /usr/pgsql-9.1/bin/`
  * `./createdb test1`
  

Mac OS X

The following are the steps to install and start PostreSQL on Mac OS X. Note that this guide covers only 'One click installer' option.

1. Install PostgreSQL using Mac OS X One click installer: http://www.postgresql.org/download/macosx/
2. Allow prepared transactions:

   • sudo su - postgres

   • Edit /Library/PostgreSQL/9.1/data/postgresql.conf to allow prepared transactions

           max_prepared_transactions = 10
     

   • cd /Library/PostgreSQL/9.1/bin

   • ./pg_ctl -D ../data restart

   • ./createdb test1 # use password you specified at Step 1.

3. Check that everything works. Still as the postgres user:

   • cd /Library/PostgreSQL/9.1/bin

   • ./psql -U postgres # use password you specified at Step 1.

           start transaction;
           select 1;
           prepare transaction 'foobar';
           commit prepared 'foobar';
     

Windows

Use the following steps to install and configure PostgreSQL on Windows:

1. Install PostgreSQL using the Windows installer: http://www.postgresql.org/download/windows/
2. Enable password authentication and configure PostgreSQL to allow prepared transactions:

• Modify the C:\Program Files\PostgreSQL\9.1\data\pg_hba.conf file to set the authentication scheme to password for tcp connections. Modify the line following the IPv4 local connections: change trust to to password. The line should look like this;

          host    all    all    127.0.0.1/32    password`
  

• Modify the C:\Program Files\PostgreSQL\9.1\data\postgresql.conf file to allow prepared transactions and reduce the maximum number of connections.

          max_prepared_transactions = 10
          max_connections = 10
  

3. Start the database server.
   • Choose Start -> All Programs -> PostgreSQL 9.1\pgAdmin III
   • Server Groups -> Servers (1) -> PostreSQL 9.1 (localhost:5432)
   • Right click -> Stop Service
   • Right click -> Start Service
4. Create the test1 database
   • Open a command line
   • cd C:\Program Files\PostgreSQL\9.1\bin\
   • createdb.exe -U postgres test1

Create a database user

1. Open a command line, login as the postgres user, and navigate to the postgres directory
   • su postgres
   • cd /usr/pgsql-9.1/bin/
2. Start the PostgreSQL interactive terminal by typing the following command:
   • psql -U postgres
3. Create the user sa with password sa and all privileges on database test1 by typing the following commands:
   • create user sa with password 'sa';
   • grant all privileges on database test1 to sa;
   • \q (to quit)
4. Test the connection to the database using the TCP connection as user 'sa'. This will validate that the change to pg_hba.conf was made correctly:
   • psql -h 127.0.0.1 -U sa test1

Add the PostgreSQL Module to JBossAS

1. Create the following directory structure: JBOSS_HOME/modules/org/postgresql/main

2. Download the JBDC driver from <http://jdbc.postgresql.org/download.html /> and copy it into the directory you created in the previous step.

3. In the same directory, create a file named module.xml. Copy the following contents into the file:

    <?xml version="1.0" encoding="UTF-8"?>
        <module xmlns="urn:jboss:module:1.0" name="org.postgresql">
            <resources>
                <resource-root path="postgresql-9.1-901.jdbc4.jar"/>
            </resources>
            <dependencies>
                <module name="javax.api"/>
                <module name="javax.transaction.api"/>
            </dependencies>
        </module>
   

Add the driver configuration to JBossAS

1. Backup the file: JBOSS_HOME/standalone/configuration/standalone-full.xml

2. Open the JBOSS_HOME/standalone/configuration/standalone-full.xml file in an editor and locate the subsystem "urn:jboss:domain:datasources:1.0".

3. Add the following driver to the <drivers> section that subsystem. You may need to merge with other drivers in that section:

        <driver name="postgresql" module="org.postgresql">
             <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
         </driver>
