One is missing, which was the issue at my Linux system:
JDeveloper didn't generate the <html> - element,
instead the <f:view> component was listed after <!DOCTYPE html> .
I added it, this resolved my problem. Edited: this issue went with updating to the current JDeveloper version. Invalid database connection can have this impacts too, interestingly.
