GlassFish is an open source application server which fully implements Java EE 5. The latest stable release is v2 UR2.

First, we'll discuss the GlassFish environment. Then we will go over the how you deploy the jee5 example. Next, we will deploy the JPA example application. Finally we show how to get a seam-gen's generated application running on GlassFish.

All of the examples and information in this chapter are based on the the latest version of GlassFish at the time of this writing.

After downloading GlassFish, install it:

$ java -Xmx256m -jar glassfish-installer-v2ur2-b04-linux.jar

After installing, setup GlassFish:

$ cd glassfish; ant -f setup.xml

The created domain's name is domain1.

Next, we start the embedded JavaDB server:

$ bin/asadmin start-database


JavaDB is an embedded database that is included with GlassFish, just as HSQLDB is included in JBoss AS.

Now, start the GlassFish server:

$ bin/asadmin start-domain domain1

The web adminstration console is available at http://localhost:4848/. You can access the web admin console with the default username (admin) and password (adminadmin). Alternatively, you could copy EAR/WAR file to glassfish/domains/domain1/autodeploy to deploy it.

You can stop the server and database using:

$ bin/asadmin stop-domain domain1; bin/asadmin stop-database

The jee5/booking example is based on the Hotel Booking example (which runs on JBoss AS). Out of the box it is also designed to run on GlassFish. It is located in $SEAM_DIST/examples/jee5/booking.

This is the Hotel Booking example implemented in Seam POJOs and using Hibernate JPA with JPA transactions. It does not require EJB3 support to run on application server.

The example already has a break-out of configurations and build scripts for many of the common containers including GlassFish.

This is very similar to the jee5 example at Section 39.2.1, “Deploying the application to GlassFish”.

  • Log in to the administration console:

  • Access the Web Applications in the menu option under the Applications left side menu.

    • Preparing for the application installation

      • Browse to examples/jpa/dist-glassfish/jboss-seam-jpa.war.

      • Select the OK button.

    • You can now access the application at http://localhost:8081/jboss-seam-jpa/.

Using Derby instead of Hypersonic SQL DB

In order for the app to work out of the box with GlassFish, we have used the Derby (aka JavaDB) database in GlassFish. However, we strongly recommend that you use another database (e.g. HSQL). examples/jpa/resources-glassfish/WEB-INF/classes/GlassFishDerbyDialect.class is a hack to get around a Derby bug in GlassFish server. You must use it as your Hibernate dialect if you use Derby with GlassFish.

seam-gen is a very useful tool for developers to quickly get an application up and running, and provides a foundation to add your own functionality. Out of box seam-gen will produce applications configured to run on JBoss AS. These instructions will show the steps needed to get it to run on GlassFish. As stated above in Section 39.2, “The jee5/booking example” it's easy to deploy either an EJB3 or a Seam POJOs application on Glassfish.

The first step is setting up seam-gen to construct the base project. There are several choices made below, specifically the datasource and hibernate values that we will adjust once the project is created.

$ ./seam setup
Buildfile: build.xml


[echo] Welcome to seam-gen :-)
[input] Enter your Java project workspace (the directory that contains your
Seam projects) [C:/Projects] [C:/Projects]
[input] Enter your JBoss home directory [C:/Program Files/jboss-4.2.3.GA]
[C:/Program Files/jboss-4.2.3.GA]

[input] Enter the project name [myproject] [myproject]
[echo] Accepted project name as: seamgen_example
[input] Do you want to use ICEfaces instead of RichFaces [n] (y, [n])

[input] skipping input as property has already
been set.
[input] Select a RichFaces skin [blueSky] ([blueSky], classic, ruby, wine,
deepMarine, emeraldTown, japanCherry, DEFAULT)

[input] Is this project deployed as an EAR (with EJB components) or a WAR
(with no EJB support) [ear] ([ear], war)

[input] Enter the Java package name for your session beans
[com.mydomain.seamgen_example] [com.mydomain.seamgen_example]
[input] Enter the Java package name for your entity beans
[input] Enter the Java package name for your test cases
[input] What kind of database are you using? [hsql] ([hsql], mysql, oracle,
postgres, mssql, db2, sybase, enterprisedb, h2)

[input] Enter the Hibernate dialect for your database

[input] Enter the filesystem path to the JDBC driver jar
[/tmp/seam/lib/hsqldb.jar] [/tmp/seam/lib/hsqldb.jar]

[input] Enter JDBC driver class for your database [org.hsqldb.jdbcDriver]

[input] Enter the JDBC URL for your database [jdbc:hsqldb:.]

[input] Enter database username [sa] [sa]

[input] Enter database password [] []

[input] Enter the database schema name (it is OK to leave this blank) [] []

[input] Enter the database catalog name (it is OK to leave this
blank) [] []

[input] Are you working with tables that already exist in the database? [n]
(y, [n])

[input] Do you want to drop and recreate the database tables and data in
import.sql each time you deploy? [n] (y, [n])

[propertyfile] Creating new property file:
[echo] Installing JDBC driver jar to JBoss server
[copy] Copying 1 file to
[echo] Type 'seam create-project' to create the new project

Total time: 4 minutes 5 seconds

Type $ ./seam new-project to create your project and then cd /projects/seamgen_example to the newly created structure.

We now need to make some changes to the generated project.


As with other examples we need to include this class for DB support. It can be copied from the jpa example into the seamgen_example/resources directory.

$ cp \ 
$SEAM_DIST/examples/jpa/resources-glassfish/WEB-INF/classes/GlassFishDerbyDialect.class \ 

You can delete this file as we aren't deploying to JBoss AS (jboss-app.xml is used to enable classloading isolation in JBoss AS)


You can delete these file as we aren't deploying to JBoss AS (these files define data sources in JBoss AS, we are using GlassFish's default data source)

  • Enable container managed transaction integration - add the <transaction:ejb-transaction /> component, and it's namespace declaration xmlns:transaction=""

  • Alter the jndi-pattern to java:comp/env/seamgen_example/#{ejbName}/local


As with the jee5/booking example we need to add EJB references to the web.xml. These references require the empty local-home to flag them for GlassFish to perform the proper binding.


This application has similar requirements as the jee5/booking example.
