Yes, Domibus is released under the European Union Public Licence 1.2, allowing free use for professional purposes.
Comparison of the two, highlighting elements that are more relevant for a Domibus installation:
| Element | WebLogic | Apache Tomcat |
|---|---|---|
| Cost | Requires a production licence | Free |
| Support | Commercial support from the vendor | Commercial support from third parties |
| Features | Advanced features (for example, assisted cluster-wide deployment & configuration) | Limited set of features |
| Administration & configuration | More complex, requires specific expertise | Simpler |
| JMS broker | Domibus can use WebLogic's embedded JMS broker | Clustered deployments require external JMS broker (ActiveMQ) |
| Framework support | May delay support for new frameworks (for example, Jakarta EE 10 available in Tomcat, but late 2025 in WebLogic) | Faster adoption of new frameworks |
| Monitoring | Better monitoring | Lacks some advanced management and monitoring tools available in WebLogic |
We advise you to choose Apache Tomcat or WebLogic depending on your circumstances and requirements.
