Versions are updated regularly

The current release list is maintained in the Software Stack Versions document. Always check it before creating or redeploying a production environment.

Select Java for a New Environment

Open the environment wizard

Open the Java tab

Switch to the Java tab and select the required application server.

Select the engine version

Choose the required application-server version and JDK distribution/version combination, then complete the remaining environment settings.

Select Java version for a new environment — Choose the Java application server and engine version in the topology wizard.

Change Java in an Existing Environment

For an already running Java environment, change the engine version by redeploying the relevant container or container layer.

Open Redeploy Container(s)

Locate the required Java container or application-server layer and start the redeployment operation.

Select the required tag

Choose the tag containing the required application-server stack and JDK distribution/version.

Start redeployment

Click Redeploy, confirm the operation, and wait for the platform to apply the changes.

Redeploy an existing Java container to another version — Select the required stack and JDK tag, then redeploy the container.

✓

Review compatibility first

Before changing Java in production, verify that the application, server, dependencies, build process, and startup options support the selected JDK version.

Expected Result

A new Java environment runs with the selected JDK distribution and version, or the existing Java container is redeployed to the chosen supported stack and JDK tag.

Important Notes

The exact available versions may change as the platform updates its certified stacks.
Existing environments can use versions that are no longer offered for new environment creation.
Redeployment can temporarily interrupt a single-node application.
Back up important application data and configuration before a production version change.
Review deployment and application logs after the operation.

Common Issues and Solutions

Issue	Solution
Required version is not listed	Check Software Stack Versions and confirm whether the release is supported for new deployments.
Application fails after redeployment	Review Java compatibility, application-server support, startup arguments, dependencies, and application logs.
Redeployment option is unavailable	Check whether another operation is running for the same environment or layer.
Application is temporarily unavailable	A single-node redeployment causes downtime. Use multiple nodes and sequential management where supported.
