B4J Question Open Street Maps - Working Demo?

RichardN · Oct 22, 2020

I have been trying to learn what is possible with Open Street Maps in the B4J environment.

The newest demo code appears to be 'MyOSMdemo' by @Starchild Here

Unfortunately I cannot get it to run. The libs appear up to date and the last post on the subject is only 6 months ago... but there appears to be a missing dependancy..... Anybody help me out here?

Waiting for debugger to connect...
Program started.

This is a deprecated class and it was removed in Java 9+: javafx/scene/shape/CircleBuilder

You will need to use Java 8.

RichardN · Oct 23, 2020

In the instructions for B4J installation we are asked to install either Oracle JDK 8 or OpenJDK 11 + OpenJFX 11.

I already have OpenJDK 11 installed. I notice that Oracle's JDK 8 also attempts to install elements supporting it's own JRE. Before I screw up my own installation..... Is it possible to install separate copies of the two SDKs and switch between the respective javac.exe in 'Configure Paths' without the installations interfering with each other?

Yes. Java 11 is not installed. It is just extracted in any folder you like.
