B4J Question B4J .jar on new machine fails

[Bruce Axtens]

What else needs to be transferred to a target machine when running a B4J app? I just copied BOJ.jar to another Win7 machine. There was no Java installed so I installed the latest JRE. When I run the .jar with the command line

java -Xmx16m -jar BOJ.jar

I get part of the screen frozen (as if the app is trying to run) and the following at the CMD terminal (truncated):

Program started.

Are you running it on a server that supports UI applications?

 

[Bruce Axtens]

Yes. I'm RDPing into a Windows 7 as per the attached.

Moved to the questions forum as it doesn't look like a bug in B4J.

What is the output of java -version?

 

[Bruce Axtens]

C:\Users\Propelis\Desktop\.joblog>java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) Client VM (build 25.31-b07, mixed mode, sharing)

Why are you limiting it to 16mb?

I'm unable to reproduce it.

Might be something with this computer display driver. Try to create a new project with a single empty form and see whether it works on this computer.

 

[Bruce Axtens]

Limiting it to 16MB because this question is derived from another where you suggested limiting to 16MB. Couldn't think of a reason not to continue using the same command line.
