Most of JDeveloper users complain about its performance. There are number of ways to improve it by tuning various parameters in configuration files. If you’ve done it already you might still face long opening of different file types (most common – .jspx, .jsf, .jsff, etc.).
That is because JDeveloper is trying to open it in Design View. It tries to visualise all components used in the file, which takes long. Opening file in Source View by default is the solution. Here is how to change that:
- Open JDeveloper Preferences
- In the left panel tree locate “File Types”
- Choose “Default Editors” tab on the right panel
- Locate necessary file type and provide “Source” value for “Default Editor” parameter
