Introduction

Oracle WebLogic Server (WLS) is a popular Java-based application server that provides a robust platform for developing, deploying, and managing enterprise-level applications. As Java continues to evolve, it's essential to keep your WLS installation up-to-date to ensure compatibility and take advantage of the latest features. In this article, we'll guide you through the process of upgrading your WLS recipe from 14.1.2 to Java 17/21, including the addition of Jakarta packages to your Maven pom files.

Prerequisites

Before we begin, make sure you have the following:

Oracle WebLogic Server 14.1.2 installed
Java 17 or 21 installed
Maven installed and configured
A basic understanding of Java, Maven, and WebLogic Server

Upgrading WLS to Java 17/21

To upgrade your WLS installation to Java 17/21, follow these steps:

Step 1: Download the Java 17/21 JDK

Download the Java 17 or 21 JDK from the official Oracle website. Make sure to select the correct platform (Windows, Linux, or macOS) and architecture (32-bit or 64-bit).

Step 2: Install the Java 17/21 JDK

Follow the installation instructions provided with the JDK download. Make sure to add the Java 17/21 JDK to your system's PATH environment variable.

Step 3: Update the WLS Installation

Update the WLS installation to use the Java 17/21 JDK. You can do this by running the following command:

wlsctl setDomainEnv -J "-Xms1024m -Xmx1024m -XX:MaxPermSize=512m -XX:+UseG1GC -XX:+UseStringDeduplication"

This command sets the Java options for the WLS domain.

Step 4: Restart the WLS Server

Restart the WLS server to apply the changes.

Adding Jakarta Packages to Maven Pom Files

To add Jakarta packages to your Maven pom files, follow these steps:

Step 1: Add the Jakarta EE 8 Repository

Add the following repository to your pom file:

<repository>
    <id>jakarta-ee-8</id>
    <url>https://projects.eclipse.org/releases/jakarta-ee-8</url>
</repository>

This repository contains the Jakarta EE 8 artifacts.

Step 2: Add the Jakarta Packages

Add the following dependencies to your pom file:

<dependency>
    <groupId>jakarta.platform</groupId>
    <artifactId>jakarta.jakartaee-api</artifactId>
    <version>8.0.0</version>
</dependency>

This dependency includes the Jakarta EE 8 API.

Step 3: Update the Maven Dependencies

Update the Maven dependencies by running the following command:

mvn dependency:resolve

This command resolves the dependencies in your pom file.

Note

It's essential to note that the packages being added are still Jakarta EE 8 versions and not above. As per the Eclipse Jakarta EE 8 release, the following packages are included:

jakarta.platform:jakarta.jakartaee-api:8.0.0
jakarta.platform:jakarta.jakartaee-web-api:8.0.0
jakarta.platform:jakarta.jakartaee-ejb-api:8.0.0
jakarta.platform:jakarta.jakartaee-jpa-api:8.0.0

These packages are not compatible with Java 17/21, and you may encounter issues if you try to use them.

Conclusion

Upgrading your WLS recipe from 14.1.2 to Java 17/21 and adding Jakarta packages to your Maven pom files can be a complex process. However, by following the steps outlined in this article, you can ensure a smooth transition and take advantage of the latest features in Java and Jakarta EE. Remember to note that the packages being added are still Jakarta EE 8 versions and not above.
