As 3DEXPERIENCE moves to the latest version, there will be changes in the Java Runtime versions required by the platform.

Why Upgrade Java?

Java is a continually evolving software, with new versions being released regularly. These updates typically include bug fixes, security patches, and functional improvements. For IT departments, staying up-to-date with the latest versions of Java helps minimize security vulnerabilities and ensures that systems are protected against the latest threats.

However, as much as you might be inclined to upgrade to the latest version, it’s crucial to remember that 3DEXPERIENCE is designed to work with specific versions of Java that have been tested and validated by Dassault Systèmes.

What Java versions are supported for 3DEXPERIENCE R2025x?

As 3DEXPERIENCE moves to R2025x, there will be changes in the Java Runtime versions required by the platform. Here are the updates:

• IBM Semeru Runtime Open Edition for Java 21.0.4 (JDK) will be the new validated platform.
• IBM Semeru Runtime Open Edition for Java 21.0.x (JDK) with x > 4 will be a compatible platform.
• Oracle JDK 21.0.x with x ≥ 4 will also be a compatible platform.

It’s important to adhere strictly to these versions, as using any other version, even if it appears to work, could cause compatibility issues or prevent you from receiving support from Dassault.

How to Update Java for 3DEXPERIENCE?

Upgrading Java for your 3DEXPERIENCE platform is a straightforward process, but it’s important to follow the proper steps to avoid any disruptions.

Step 1: How do I check which Java version I am currently using?

Before you upgrade, it’s essential to know which version of Java you are currently using. This will help ensure you’re updating to the correct version. To check your Java version, you can run the following command in your command line or terminal:

java-version

This will display the version of Java currently installed on your system.

Step 2: Uninstall the old Java version

If your current Java version is no longer supported, you’ll need to uninstall the old version. Go to your Control Panel (Windows) or System Preferences (Mac), locate the old Java version, and uninstall it.

Step 3: Download and install the new Java version

Next, download the required Java version from a trusted source. You can get the IBM Semeru Runtime Open Edition or Oracle JDK from their respective websites.

• IBM Semeru Runtime Open Edition for Java 21.0.4 (JDK)
• Oracle JDK 21.0.x

Step 4: Initiate installation

Start the .msi file that has been downloaded in the previous step to initiate the installation. Click Next.

Step 5: Terms and conditions

Accept terms and conditions and click Next.

Step 6: Set registry keys

Use the drop-down arrows and set Java Home variable and Javasoft (Oracle) registry keys as “Will be installed on local hard drive.” Once done, click next.

Step 7: Complete installation

Click on Install and wait for the installation to be completed. Once done, click Finish to close the installation window.

Step 8: Restart 3DEXPERIENCE services

Once the new Java version is installed and verified, restart your 3DEXPERIENCE services to ensure the platform is using the updated Java version.

What if I install Java in a different directory?

During installation, ensure that Java is installed in the same directory as your previous Java version. For instance, if your previous installation was in D:\Java, install the new version in the same directory. If the installation path changes, 3DEXPERIENCE may not be able to locate Java, which could prevent the platform’s services from starting correctly.

How do I check which Java version I am currently using?

After installation, verify that the correct version is now in place. Use the java-version command to confirm the version change.

Please note the supported operating systems according to “Operating System Prerequisites” in the DS License Server Installation and Configuration Guide.

Virtual machines are supported only with a Windows 2016 Server cluster.

Network card teaming is not supported.

Please download DSLicTarget.exe

After the download, the file DSLicTarget.exe is located in your Downloads folder.

Please open Windows Explorer and take a look at your Downloads folder.

In Windows Explorer, click into the address line at the top, enter “cmd” (without quotation marks), and press the key:

A command prompt (cmd.exe) window appears.
Type the command “DSLicTarget –t”:

Select the menu “Edit\Mark”:

Mark the output of the command “DSLicTarget –t” with the left mouse button:

Copy the marked text with the key to the Windows clipboard.

Now you can insert the copied text from the Windows clipboard into your email application and send it to your contact at TECHNIA.

This guide will explain how to configure a client machine to request and use a (concurrent or floating) license from a DSLS license server.

1. Ensure a Dassault Systèmes product is installed (e.g. CATIA V5)
2. Using a ‘Windows File Explorer’, browse to the folder: –

C:\ProgramData\DassaultSystemes\Licenses

Note: The folder ‘ProgramData’ is normally a hidden folder. You can type that piece into the address bar OR un-hide the folder.

Note: If the ‘Licenses’ folder does not exist, browse to C:\ProgramData\DassaultSystemes and create a ‘New Folder’ called ‘Licenses’ as shown below:

Inside the Licenses folder, open the DSLicSrv.txt file.

Note: If the ‘DSLicSrv.txt’ text file does not exist, create a ‘Text Document’ called ‘DSLicSrv’ as shown in the pictures below: –

Caution: Ensure you do not finish up with a doubled-up file extension. The file MUST be called DSLicSrv.txt and NOT DSLicSrv.txt.txt It is suggested you have ‘Hide extensions for known file types’ deactivated in Folder Options to spot this error.

In the text file ‘DSLicSrv.txt’, enter the required information in the following format: :

Note: The ServerName should be entered exactly as it is named.

The licensing port number by default is 4085, so please use 4085 (Unless this was changed during DSLS installation). e.g. If the License server is called ‘server1’ the text file should have a line server1:4085 .

Also note: If the DSLS license server is the same PC as the license client i.e. server and client on the same PC, you may use the name localhost e.g. localhost:4085

Save the text file and proceed to open your DS Application. Do not forget, the first time you start the application, it will ask you to select a license.

Note: If there is an additional server, e.g. server2, simply enter it in the next line.

Troubleshooting

Cannot get a license from the license server? Check the following:

1. Is Window’s firewall off on both the client and server?
   Action: Temporarily disable the firewall on the server and the client. If it starts working, port 4084 and/or 4085 are being blocked.
2. Can you ping the server (using the name you entered)?
   Action: Potential misspelling of server name or network problem.
3. Have you got the latest DSLS?
   Action: The DSLS version installed should at least equal the version of the Dassault application you are using.
4. Is the spelling of the server name and/or port number correct?
   Action: Correct any misspelling of server name or port number.
5. Is the path to the DSLicSrv.txt (and indeed the name of the DSLicSrv.txt file) spelt correctly?
   Action: Correct any misspelling of the folder name(s) or the DSLicSrv configuration filename.
6. Is the license server configured correctly, with the licenses installed and the license service running?
   Action: Configure the DSLS license server correctly.

If you have not yet installed Dassault Systèmes License Server (DSLS), please read the following KB article first:

EN: DSLS Installation

This guide will explain how to configure the Dassault Systèmes License Server (DSLS) and enroll DSLS licenses using the License Administration Tool provided by Dassault Systèmes.

Please save the .LICZ attachment from the licensing E-mail you received, into an easy to find folder on the license server.

1. Once the DSLS licensing app is installed on the server, go to ‘Start > Programs > DS License Server > License Server Administration’ to run the admin tool on the server.

2. To create a new server click the Servers‘ tab and click ‘New‘

3. Enter localhost‘ as the server name and click ‘Ok‘ to continue (if you chose a different port earlier, change the port to match)

4. Select your server from the list and click the Connect function from the ‘Servers’ menu at the top OR ‘Right mouse button’ on the server in the list and select ‘Connect’.

Note: The server will become bold when connected as shown below.

Note: However, if no licenses have been installed yet (and the server is not activated), there will be a red cross on the ‘Server status’ icon as shown below.

5. Now you can enroll your license key(s) by clicking the License‘ tab and then ‘Enroll‘

6. Locate the license key (licz) and select Open

7. The license(s) contained in the licence file will be enrolled and a message like the one below will appear. Click ‘OK’

The above indicates successful license enrollment, and the system is ready to use. You may now close the License Administration Tool. The license file you have (xxxxx.LICZ) may be discarded.

Note: If you get an error message, the primary reason is probably that you are trying to enroll the license(s) on a server where the DSLS Target ID does NOT match the target ID that the license file was created for.

To configure the client computer please continue with KB article: Configuring DSLS Client

Link: EN: Configuring DSLS Client

It is recommended to install the latest DSLS (DS License Server) release.

The minimum requirement for using a current Dassault Systèmes product is a DSLS Server Release that matches the year of the respective product release, e.g., CATIA V5-6R2022 requires at least DSLS License Server Release 2022x. Older CATIA releases with DSLS licensing will still be functional.
