Changing preference to open pages in Source View instead of Design View in Oracle jDeveloper

Whenever we open files like JSP Page Fragments, JSP Pages, HTML code, etc. they always open in Design view instead of source code which makes large files or files with many components to load slower.

So, do we have any way which enables Jdeveloper to open files directly in Source Code view instead of opening the Design editor?
Yes, we can change this default setting. To change this setting follow these steps:

• Go to Tools Menu, then click Preferences

• Preferences dialog will appear. In files Files Types section, switch to Default Editors Tab. Select the file type for which you want to change the default editor and then change the editor from Default Editor drop down at the bottom. For example, here we have changed the default editor of JSP Source file type to Source. So from now whenever you open any file of type JSP Source, JDeveloper will open its source code instead of design view.
