I am some problems with my Jdeveloper 18.104.22.168.0. Recently, I noticed that my Jdeveloper is not working properly. When I build pages, save and rebuild the view-controller, when I ran the application or refresh it in Internet explorer, it does not reflect the changes that I made rather, it still displays the previous state of the application.
What is responsible for this?
Using your operating system, delete the whole classes folder of the model and the view controller project and try again. The classes folder hold another folder named '.data' which sometimes causes trouble. It's Dave to remove the whole classes folder as jdev will recreate it again.
The are two possible problems. First is that your web-inf folder may contain old temporary files in a classes of temp folder, which you can delete. Second your browser serves from its cache instead from the server.
To test the second case try the url from a different browser and see is you see your changes.
