--Create a WAR file in Gradle containing Java Servlet and JSP --Install GlassFish 5.1.0 --Deploy the WAR file to GlassFish 5.1.0 --Operation check environment: Java 8 (AdoptOpenJDK 1.8.0_265) + GlassFish 5.1.0 (Java Servlet 4.0 + JavaServer Pages 2.3) + macOS Catalina + Gradle 6.5.1.

What is GlassFish 5.1?

GlassFish 5.1 is a Jakarta EE 8 and Java EE 8 compliant web application server. It supports Java Servlet 4.0 and JavaServer Pages 2.3.

Eclipse GlassFish

Eclipse GlassFish is a Jakarta EE compatible implementation sponsored by the Eclipse Foundation. Eclipse GlassFish 5.1 is also Java EE 8 Compatible.

Install Java 8

If Java 8 is not installed, install it with Homebrew etc. and set the environment variables JAVA_HOME and PATH.

$ brew tap AdoptOpenJDK/openjdk

$ brew cask install adoptopenjdk8

$ /usr/libexec/java_home -v 1.8

$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

$ export PATH=${JAVA_HOME}/bin:${PATH}

Note that in Java 11 and Java 14, Glassfish 5.1.0 will not start with the following error.

$ ./glassfish5/bin/asadmin start-domain
Exception in thread "main" java.lang.NullPointerException

Create a WAR file

Create a WAR file with the Gradle build task.

$ gradle build

Make sure the WAR file is generated.

$ file build/libs/mywebapp-1.0.war 
build/libs/mywebapp-1.0.war: Zip archive data, at least v1.0 to extract

Install GlassFish 5.1.0

Install according to the official manual Installing Eclipse GlassFish Server 5 \ .1.

From Eclipse GlassFish \ | projects \ .eclipse \ .org glassfish-5.1.0.zip (Eclipse GlassFish 5.1.0, Full Profile) To download.

Extract the downloaded glassfish-5.1.0.zip to the installation directory.

$ unzip glassfish-5.1.0.zip

Simply download the zip file and unzip it to complete the installation.

Start GlassFish

Quick Start for Basic Features -Starting and Stopping the Default Domain Start according to.

$ ./glassfish5/bin/asadmin start-domain
Waiting for domain1 to start ......
Successfully started the domain : domain1
domain  Location: /Users/foo/glassfish5/glassfish/domains/domain1
Log File: /Users/foo/glassfish5/glassfish/domains/domain1/logs/server.log
Admin Port: 4848
Command start-domain executed successfully.

Once started, you can manage the state of GlassFish at Administration Console http: // localhost: 4848 /.

Deploy the WAR file to GlassFish 5.1.0

It can be deployed with the asadmin deploy command. Details of the command can be found in the reference manual deploy.

$ ./glassfish5/bin/asadmin deploy --contextroot=mywebappcr --name=mywebappname /Users/foo/mywebapp/build/libs/mywebapp-1.0.war
Application deployed with name mywebappname.
Command deploy executed successfully.

The deployed WAR file is copied and expanded under the installation directory.

$ find . | grep mywebapp

Operation check

Check the operation of the deployed Web application.

(I'm a little worried that Servlet / 3.1 is output even though it should support Servlet 4.0)

$ curl --include http://localhost:8080/mywebappcr/myservlet
HTTP/1.1 200 OK
Server: GlassFish Server Open Source Edition  5.1.0 
X-Powered-By: Servlet/3.1 JSP/2.3 (GlassFish Server Open Source Edition  5.1.0  Java/AdoptOpenJDK/1.8)
Content-Type: text/html;charset=utf-8
Content-Length: 118

Servlet: Hello Servlet World!<br>
GlassFish Server Open Source Edition  5.1.0 
$ curl --include http://localhost:8080/mywebappcr/myjsp
HTTP/1.1 200 OK
Server: GlassFish Server Open Source Edition  5.1.0 
X-Powered-By: JSP/2.3
Set-Cookie: JSESSIONID=0123456789abcdef0123456789ab; Path=/mywebappcr; HttpOnly
Content-Type: text/html;charset=utf-8
Content-Length: 230

JSP: Hello JSP World!<br>

java.vm.name: OpenJDK 64-Bit Server VM<br>
java.vm.vendor: AdoptOpenJDK<br>
java.vm.version: 25.265-b01<br>

Undeploy the web application

You can remove the deployed web application with the asadmin undeploy command.

$ ./glassfish5/bin/asadmin undeploy mywebappname
Command undeploy executed successfully.

Stop GlassFish

You can stop it with the asadmin stop-domain command.

$ ./glassfish5/bin/asadmin stop-domain
Waiting for the domain to stop .
Command stop-domain executed successfully.
