Hello World - Code Sample
By rovarghe on Feb 26, 2013
Complete JDeveloper Application with two Projects showing how to write a Deployment Extension and plug it into the IDE. The first extension adds the deployment code, the second extension surfaces a menu item labelled "Say Hello World" under the "Run" menu. For explanations see this blog entry.
Before running the project, go to Project Properties/Extension and select your target platform.
To run, right-click and select "Run Extension", or you can also "Deploy to Target Platform" and run the IDE manually.
