B4J Question B4J V4.7 problem

[gezueb]

Hi, I just updated B4J to version 4.7 because I want to use File.DirData. However, when I compiles my program that was running flawlessly before I get 14 errors on startup (not on compile) like this one

Erel, I have updated both the Java jdk and the run time machine to version 8.111. No luck, same behaviour. The error occurs on process global initialization before any of my code is executed.

Did you already pointed the path to new jdk? in tools -> configure paths.

Thank you, Enrique and Erel, you hit the nail on the head. I was not aware that the jdk does not update but creates a new version. It works fine now after I redirected the path. I would suggest that the download instructions of b4j would be a bit more explicit about these requirements, maybe others are as ignorant as I am about java and its components. If I would have a facebook account I would send you many likes! Georg
