[JAVA] [Jakarta EE 8 application development with Gradle] 1. Environment construction
Introduction
I am developing an enterprise application using Jakarta EE (Java EE) in my business. Until now, I have learned and developed while reading reference books, but I did not have a document that suits me, from environment construction to development procedures, so I would like to summarize my knowledge so far in a serial format. ..

1. Environment construction
OpenJDK 11 installation
This time I will use Azul Zulu.
Since payara server 5.192 supports Java 11, it is set to OpenJDK 11.
https://jp.azul.com/downloads/zulu-community/?&architecture=x86-64-bit&package=jdk
From the link above, click to download the Java 11 (LTS) Windows version of the msi.
Run the downloaded MSI file.
Click Next, leave the installation folder at its default, and click Next.
Click Install to start the installation.
When the installation is complete, the screen below will be displayed. Click Finish.
Then set the environment variables.
Search for "environment variables" in the Windows settings and select "Edit system environment variables".
Click the environment variable.
Click New system environment variable.
Set the following system environment variables. Enter as shown in the table below and click OK.
| Variable name | Variable value |
|---|---|
| JAVA_HOME | C:\Program Files\Zulu\zulu-11 |
Start the command prompt, execute "java -version", and if the following result is displayed, the installation is complete.
If you have another JDK installed, you may not get the above results. In that case, open the system environment variable settings and the beginning of Path is
\Program Files\Zulu\zulu-11\bin
Please change it to.
## PostgreSQL 12 installation
Use PostgreSQL as the database server.

Create a payara folder directly under the C drive, and create a payara-5.201 folder in it.

Unzip the downloaded file and place the unzipped payara5 folder inside the payara-5.201 folder. The contents of the `C: \ payara \ payara-5.201 \ payara5` folder after placement will be as shown in the screen below.
Next, make the initial settings for payara server.
Start a command prompt and go to the `C: \ payara \ payara-5.201 \ payara5 \ bin` folder.
Start payara server.
Type ʻasadmin start-domain` to run it.
