Deploying Jakarta EE 9 applications to Glassfish v6 using Cargo maven plugin

From the Jakarta EE mail subscription, I think Jakarta EE 9 is ready for the public and the official announcement will come soon in a few days.

In the former Jakarta EE 8 starter boilerplate , I have described how to deploy a Jakarta EE 8 application on Glassfish v5, in this post, I will update it and try to deploy the Jakarta EE 9 sample application to a Glassfish v6 application server.

Prerequisites

Make sure you have installed the following software.

• Java 8, yes, Glassfish v6 still only supports Java 8, the next 6.1 will focus on Java 11 support. Oracle JDK 8 or AdoptOpenJDK 8 is recommended.
• Download and install Glassfish v6 , this is required when you are deploying the applications via the existing and remote runtime configuration.
• Download and install Apache Maven .
• Get to know the basic of Cargo maven plugin.

In this post we still use the Cargo glassfish5x container to perform the deployment. Cargo will include a new glassfish6x container in 1.8.3 for Glassfish v6.

Deploying the applications

Clone the Jakarta EE9 starter boilerplate repository into your local disk.

Open a terminal and switch to the project root folder, execute the following command to build and deploy this Jakarta EE 9 application to Glassfish v6 .

mvn clean verify org.codehaus.cargo:cargo-maven2-plugin:1.8.2:run 
-Dcargo.maven.containerId=glassfish5x   
-Dcargo.maven.containerUrl=https://download.eclipse.org/ee4j/glassfish/glassfish-6.0.0-RC2.zip  
-Dcargo.servlet.port=8080

This command will use Maven to build the project, and then call cargo maven plugin to download a copy of Glassfish v6 from the the specified URL, and then try to prepare a new domain configuration for the application deployment, then start the new created domain, and final deploy the deployable file( target\jakartaee9-starter-boilerplate.war).

You will see info similar to the following when the deployment is successful.

The above command is equivalent to the following config in the project pom.xml file.

<properties>
	<cargo.servlet.port>8080</cargo.servlet.port>
	<cargo.zipUrlInstaller.downloadDir>${project.build.directory}/../installs
	</cargo.zipUrlInstaller.downloadDir>
</properties>
<build>
	<plugins>
		<plugin>
			<groupId>org.codehaus.cargo</groupId>
			<artifactId>cargo-maven2-plugin</artifactId>
			<configuration>
				<container>
					<containerId>glassfish5x</containerId>
					<zipUrlInstaller>
						<url>https://download.eclipse.org/ee4j/glassfish/glassfish-6.0.0-RC2.zip</url>
						<downloadDir>${cargo.zipUrlInstaller.downloadDir}</downloadDir>
					</zipUrlInstaller>
				</container>
				<configuration>
					<home>${project.build.directory}/glassfish6x-home</home>
					<properties>
						<cargo.servlet.port>${cargo.servlet.port}</cargo.servlet.port>
					</properties>
				</configuration>
			</configuration>
		</plugin>
	</plugins>
</build>

You can run the following command instead with the above configuration.

mvn clean verify cargo:run

Here we use the run goal, it will keep the application server running until we sending a CTRL+C command to stop it.

If you have prepared a copy of Glassfish v6, you can reuse the existing Glassfish and domain configuration.

<properties>
	<glassfish.home>[ The existing glassfish6 dir]</glassfish.home>
	<glassfish.domainDir>${glassfish.home}/glassfish/domains</glassfish.domainDir>
	<glassfish.domainName>domain1</glassfish.domainName>
</properties>
<build>
	<plugins>
		<plugin>
			<groupId>org.codehaus.cargo</groupId>
			<artifactId>cargo-maven2-plugin</artifactId>
			<configuration>
				<container>
					<containerId>glassfish5x</containerId>
					<type>installed</type>
					<home>${glassfish.home}</home>
				</container>
				<configuration>
					<type>existing</type>
					<home>${glassfish.domainDir}</home>
					<properties>
						<cargo.glassfish.domain.name>${glassfish.domainName}</cargo.glassfish.domain.name>
						<cargo.remote.password></cargo.remote.password>
					</properties>
				</configuration>
			</configuration>
		</plugin>
	</plugins>
</build>

In the above codes, set the configuration type to existing, and specify the domain name to the default domain1, when run the following command it will reuse the existing domain1 to deploy the applications.

mvn clean verify cargo:run

If you want to deploy your applications to a running Glassfish v6 server(esp. it is running on a different machine), try to configure a runtime configuration and use a remote deployer to perform the deployment.

<plugin>
	<groupId>org.codehaus.cargo</groupId>
	<artifactId>cargo-maven2-plugin</artifactId>
	<configuration>
		<container>
			<containerId>glassfish5x</containerId>
			<type>remote</type>
		</container>
		<configuration>
			<type>runtime</type>
			<properties>
				<cargo.remote.username>admin</cargo.remote.username>
				<cargo.remote.password></cargo.remote.password>
				<cargo.glassfish.admin.port>4848</cargo.glassfish.admin.port>
				<cargo.hostname>localhost</cargo.hostname>
			</properties>
		</configuration>
	</configuration>
	<!-- provides JSR88 client API to deploy on Glassfish/Payara Server -->
	<!-- WARNING: deployment client is not available in Glassfish v6.0 -->
	<dependencies>
		<dependency>
			<groupId>org.glassfish.main.deployment</groupId>
			<artifactId>deployment-client</artifactId>
			<version>5.1.0</version>
			<!--<version>${glassfish.version}</version>-->
		</dependency>
	</dependencies>
</plugin>

In the above configuration:

• cargo.hostname is the target server you want to deploy to
• cargo.remote.username and cargo.remote.password is administrator account used to deploy
• The remote deployer depends on a deployment-client archetype, here we use the version 5.1.0, there is no new version for Glassfish v6, and JSR 88 spec is removed in Jakarta EE 9.

For a remote container, you can not control the start and stop lifecycle as the former configurations, use deploy and undeploy goal to perform the deploy and undeploy tasks.

# deploy applications
mvn clean verify cargo:deploy
# undeploy
mvn cargo:undeploy

When the application is deployed successfully, use curl to verify if the deployed application is running.

curl http://localhost:8080/jakartaee9-starter-boilerplate/api/greeting/Hantsy
{"message":"Say Hello to Hantsy at 2020-11-14T15:56:10.099"}

I have added the above configurations with different Maven profiles in the pom.xml. Check out the source codes and explore yourself.
