Got this error (below) in the log window when selecting Designer on a jspx file.
I'm only 3months into Java SE work and 2 days into using JDeveloper and so I really don't know where to start debugging this, and apologies if specific information is required - there are so so many files and options everywhere, but if requested I will provide the info.

If I create a new JSPX page from a blank with no backing, I get this:

Appreciate it might be anything causing this, so could do with a guru to take walk me through what we have setup - and I will learn as we go through. No idea how all this works having come from Java Desktop and APIs/banking. First time I've used ADF/JSPX.
Thank you in advance.
