Frank Nimphius just posted a message called: Oracle JDeveloper: Finding the physical location of an imported Java class. Very usefull posting. As usual, there’s more than one way to do something with JDeveloper. Here’s how i find the physical location of java class:
This is usually more convenient than toolstips. Tooltips have a habit of disappearing when you have only read half of them.
Btw, if JDeveloper can’t find the class you’re trying to locate, and you are sure you are using the class in your application, so JDeveloper should be able to find it, try selecting another project in your workspace. JDeveloper can only go to a class that you’ve added to the libraries of your selected project.
