I'm using JDeveloper 10.1.3.0.4, and everytime I double click in Application Navigator onto a .jsp file, it is opened directly into design view. Instead I'd like it to be opened directly into source view. Is it possible ? Thanks.
In menu Tools -> Preferences...
Select File Types on the left
Click tab 'Default Editor'
Select the File Type (JSP Source in your case) and change the default editor.
