Downloading Java with Java Management Service: Script-friendly Oracle Java downloads now available through OCI

Oracle is excited to announce the launch of scriptable Java downloads through the Java Management Service (JMS) via the Oracle Cloud Infrastructure (OCI) service. This new capability is tailored to meet the needs of Java developers, administrators, and software providers.

Learn how JMS Java Downloads let you download up-to-date Java versions into your automated build and deployment system with script-friendly downloads, token-based authentication, and comprehensive reporting – on OCI, third-party cloud, and on premises including desktop environments.

Script-Friendly Java downloads, for all releases, including those past end-of-permissive-licensing (e.g. JDK 8 and 11)

oracle.com/javadownload allows for no-click script-friendly downloads of JDK versions under the No Fee Terms and Conditions (NFTC) which currently includes Oracle JDK 17 and 21. JMS Java Download provides more flexibility to customers by offering script-friendly downloads for all supported JDK versions, including versions that, being under the Oracle Technology Network (OTN) License, require license acceptance, such as updates for Oracle JDK 8 and JDK 11.

Token-Based Authentication for Hassle-Free Downloads

License-acceptance tokens are the key to enabling automatic downloads for all Java versions via scripts and in dockerfiles. Customers can generate tokens that allow Oracle’s download servers to validate that the applicable license terms for each JDK version have already been accepted. By using these user-generated tokens, administrators and developers can download Oracle Java binaries without having to log in and re-accept license terms for each download. Each token is linked to an individual OCI tenancy and to a Java version. You can create multiple tokens for each Oracle Java version.

Download JDKs from wherever you need it

Oracle Cloud Infrastructure is available from 46 public cloud regions in 23 countries. JMS Java Download service allows you to create tokens and download Java from any of those regions. This allows developers and system administrators to choose the location closest to the systems downloading the JDK and to comply with requirements that mandate downloads from particular locations.

The domain for the download command used in your scripts and dockerfiles will clearly indicate the region from which Java will be downloaded.

Users of OCI dedicated regions can reach out to their Oracle Representatives to set up JMS Java Download Services in their dedicated servers.

Finding the right update version

Oracle releases quarterly updates to all supported Java versions with critical security and functional fixes as well as performance upgrades. We strongly recommend that users update their Java runtimes to an up-to-date version as soon as possible.

Latest download commands

To allow for scripts and dockerfiles to remain unchanged, yet get the latest JDK version, we offer the “latest” download commands.

Download locations with the /java/latest/ provide you with the latest release in the selected version. Here is how to use the download command:

Copied to ClipboardError: Could not CopyCopied to ClipboardError: Could not Copy

curl -H "token: <token value>" -L -O <domain>/java/<version>/latest/<fileNameWithExtn>

curl -H "token: <token value>" -L -O <domain>/java/<version>/latest/<fileNameWithExtn>

For example, if you need to retrieve the latest version of JDK 17 using scripts, without having to update the scripts, use the latest download command for JDK 17 (/java/17/latest/jdk-17_windows-x64_bin.zip) in your script. This command ensures you always get the latest version of JDK 17. For instance, if you run this command in Nov 2023, you will get JDK version 17.0.9, and after the Jan 2024 critical patch update, you will get JDK 17.0.10. The filename in the latest download command specifies only the Feature/Major version (17, instead of 17.0.9 or 17.0.10)

Archive download commands

It is also possible to request a specific JDK version for download. For this, we offer the “Archive” download commands.

Download locations with /java/archive/ provide a specific release. Here's how the archive download command can be used:

Copied to ClipboardError: Could not CopyCopied to ClipboardError: Could not Copy

curl -H "token: <token value>" -L -O <domain>/java/<version>/archive/<fileNameWithExtn>

curl -H "token: <token value>" -L -O <domain>/java/<version>/archive/<fileNameWithExtn>

For example, if you need to retrieve JDK 17.0.9, regardless of whether is the latest, use the archive download command associated with the required binary (e.g., /java/17/archive/jdk-17.0.9_windows-x64_bin.zip) in your script. The filenames in the archive download commands specify the exact JDK version. This command ensures you always get JDK 17.0.9.

Availability of the download commands

It is worth noting that the “latest” download commands will work only for as long as there is an up-to-date update for that JDK available. The archive download commands will work for at least two years after the release of that update version.

The maximum value for token expiration is either two years from the EOSL date of the associated JDK version or, in the case of newer LTS releases, the time when the JDK version is expected to change to a different license agreement. On approaching the change of license terms for the newer LTS JDK versions, JMS will provide provisions to accept the new terms, enabling you to extend the token expiration date to ensure your scripts continue running. You will need to accept the new terms before downloading under the new license agreement.

Comprehensive Reporting for Informed Decision-Making

Java Download provides download reports to help you understand download trends across your organization. These reports are available for download directly from OCI, making it easy for you to analyze how many times your systems have downloaded each version.

The reports include information about:

◉ The number of downloads per main Oracle Java version.

◉ The number of downloads for each Oracle Java release under each main Oracle Java version.

◉ The number of downloads per platform, and architecture (e.g. Linux, Windows, or macOS, x86_64 or aarch64).

◉ The time when each download was initiated.

Understanding Java download trends and patterns allows you to make better-informed decisions.

Getting Started: Create an Account on Oracle Cloud Infrastructure (OCI)

To benefit from the full capabilities of JMS Java Download, you'll need an Oracle Cloud Infrastructure (OCI) account. If you don’t already have one, you can create a free account, which includes a free time-limited promotional trial.

What’s New in Java Management Service

Last June we announced a new cloud service running on Oracle Cloud Infrastructure (OCI) to help Java users manage, monitor and maintain their Java environments.  It enables the use of OCI to observe and manage Java in the enterprise – on OCI, on premises, or on other clouds.

Java Management Service (JMS) has come a long way since then.

Now deployed globally across all OCI regions, it available to any and all Java users for no additional charge on OCI, beyond the minimal cost of monitoring, logging and alarms. See the pricing information below for more on these minimal operations charges and options.

Several times each year, a new release of JMS is made available with new features and functionality. The latest release, 4.0, includes some interesting new capabilities, the most exciting of which are the ability to

Customers can:

• Use insights from JMS to optimize workloads across the enterprise (desktop, server, cloud)
• Protect your Java SE investments by identifying outdated Java installations, unauthorized applications, and Java runtime and application mismatches. For example, you expect your application to be using JDK 11, but via JMS you discover it is actually using JDK 8.

JMS helps systems administrators answer questions such as:

• Which vendors are providing the Java installations in my environment?
• Are my applications using their intended Java installations?
• Are unauthorized applications running?
• How many outdated Java installations do I have?

As the stewards of Java, Oracle can provide answers to these questions. Oracle is uniquely positioned to leverage its expertise to gain critical insights into Java application behavior, compliance, and performance.

How does it work?

Java Management Service relies on the Java Usage Tracker to report Java usage. The Java Usage Tracker tracks how Oracle Java Runtime Environments are being used in your systems and captures the JRE version, vendor, the application being run, and other details. Additionally, JMS also periodically performs a file scan to detect Java runtimes that are not captured by the Java Usage Tracker because they aren't being used, or they don't have the Java Usage Tracker capabilities.

For example, OpenJDK binaries will be detected by JMS through file scanning but won't be able to show you the usage associated with them, because OpenJDK binaries, in contrast to the more robust Oracle JDK, don't have Java Usage Tracker capabilities. Java Usage Tracker is available for all releases of Java 7* and later, and also for the following older Java releases:

• 6u25 and later updates
• 5.0u33 and later updates
• 1.4.2_35 and later updates

Pricing

For customers using Java SE Subscription for on-premises deployments and for anyone using Oracle Java SE on OCI (whether or not they are Java SE Subscribers), there is no additional fee for using JMS beyond the minimal cost of monitoring, logging and alarms as described above.

For those who use Java SE on other clouds, or who want to monitor JDKs from other vendors or open source providers, we recommend the purchase of a Java SE Subscription which allows for the full benefits of JMS and much more. This 1:12 minute video provides a snapshot of the benefits included with Java SE Subscription.
