I agree with PaulG. I think there is no direct way to find those
files. There are only two options. If you are using templates (Content
classes) to create jsp, then the way to find all of them in project
structure navigator, is simply to check it as PaulG suggest:
SmartTree > Administer Content Classes > Folder > Content Class >
Instances. But if you are using jsp as a file added for example via
Asset Manager, I think better solution would be to check there those
files, and where they are (SmartTree -> Administer Project Setting -
>Folder then choose folder in which You keep jsp files, edit its
content and then choose file via asset manager you want to find, and
on the right side you will find "Show Usage".).
Well, RQL is also good solution, but it depends how much time do you
have and how many files there will be to find, if there is a big
amount of files - RQL solution can be better.
