If you use the port parameter with Javeleon, no automatic reload is executed. The old Javilion plug-in sent a reload event after a java file was changed, but that was a bug. With the current version, you can configure, for which file extension you want to send a reload event.

The configuration is saved per project.

Project properties		Open the project properties (right click on the project / Properties) and be sure that Javilion nature has been added to your project! Otherwise it is not possible to change the configuration.
Preferences		Open the preferences (Window / Preferences) and set the default values! The default values are used when you Reset the settings in your project setup.

Have fun
