We advise you to choose Apache Tomcat or WebLogic depending on your circumstances and requirements.

The eDelivery AS4, SMP, BDXL and ebCore Party Id 2.0 were adopted on 4 December 2024. This adoption affects the sample implementation software as follows:

1. Support for new specifications:
   • eDelivery Building Block plans to incorporate the new specifications in upcoming sample software releases.
   • All sample software will support both old and new specifications.
   • Users can configure which specification version to use: old specifications, new specifications or a mixed approach.
2. Timeline and planning for 2025 and beyond: Support plans may be adjusted based on factors such as budget allocation in the DEP Work Program 2025-2027.
3. Backwards compatibility:
   • Different solution providers may adopt varying approaches to backwards compatibility.
   • It is recommended to contact other solution providers directly to understand their compatibility strategies.
4. Ecosystem impact:
   • Ecosystem owners should assess the impact based on the combination of products used within their environments.
   • Proper planning is essential to ensure seamless integration and functionality.

Upgrading to the latest version of Domibus is not mandatory but is recommended to benefit from the latest features and security enhancements.

Key considerations:

• Custom plugins: Ensure that custom plugins are updated to remain compatible with the new Domibus version.
• Support periods:
  • Standard releases: Supported for at least one year from the release date of their minor version.
  • Long-Term Support (LTS) releases: Supported for at least two years from the release date of their minor version.

Additional information:

• Support expiration dates: Refer to Domibus releases and Support arrangement for exact expiration dates of the support periods.
• LTS identification: Releases under Long-Term Support are clearly identified in Domibus releases to assist in your upgrade planning.

By staying updated, you ensure that your Domibus installation remains secure, supported and equipped with the latest functionalities.

You can download Domibus, an open-source eDelivery sample implementation of an AS4 Access Point, for free from the Domibus release page.

Domibus currently supports Tomcat, WebLogic and WildFly. However, WildFly support will be phased out from Domibus 6.0 onwards. If you are using WildFly, please consider migrating to Tomcat or WebLogic to ensure continued support and security patches. Consult the Domibus releases for specific timelines and migration guidance.

Domibus is developed in Java, making it compatible with any platform that supports Oracle Java JRE/JDK 8. It has been successfully deployed and tested on Windows and Linux. For more information on supported platforms for specific Domibus versions, please check the Domibus release page.

According to the current plan, Domibus will begin supporting Elliptic Curve certificates starting from Version 6.0. For detailed information about this release and future updates, please refer to the Domibus Release Roadmap.
