By default, OpenXava is compiled with Java 6, so you can use OpenXava with
WebSphere 8 and WebLogic 10. However, the application server included in
the OpenXava distribution is Tomcat 9 (since OpenXava 6) that requires
Java 8. Therefore, you need to use Java 8 (or better) to follow the
introduction documentation to OpenXava.
If you want to use Java 6 with
OpenXava follow the next steps:
- Install a JDK 6 in your computer.
- In Eclipse choose it: Windows > Preferences > Java >
Installed JREs : Choose the JDK 6
- Download and install Tomcat 7: https://tomcat.apache.org/download-70.cgi
- Configure your Eclipse to use the just downloaded Tomcat 7 instead
of the Tomcat included with OpenXava.
