B4J Question (SOLVED) Error trying to run JAR and standalone package - decodeDriverLicense

Johan Schoeman · Dec 4, 2021

Hello all

Attached B4J project refers. It uses bcprov-jdk16-1.43.jar that you can download from the web. When compiling it in B4J it runs fine - no problem whatsoever (release mode and debug mode). When I compile it to a Standalone package and run it with run_debug in the Objects\temp\build folder of the standalone package I get the following error:

B4X:

Anyone with a solution for this? I am a bit lost with this....

This works:

B4X:

#AdditionalJar: bcpkix-jdk14-1.48
#AdditionalJar: bcprov-jdk14-1.48
#PackagerProperty: VMArgs = --add-opens b4j/org.bouncycastle.jcajce.provider.asymmetric.rsa=java.base

Will probably work with your version as well.

No idea about the first error!
Your second error looks like you are using Java 8 to run a Java 11 compiled jar.

Run java --version to get the actual jdk you are using. As agraham stated this could be jdk8

Try java -version

Try java -version

It says:

Ide reports what you have in your settings

In CMD CD into your jdk / bin folder and from there do the Java -jar your.jar

This will use the current folder java

It's possible that time ago you set the JAVAHOME enviroment variable.
So, having on disk both 1.8 and 1.11 when your run a jar, the JAVAHOME calls the 1.8 version

Java 8 by default is installed with an entry in the Path environment variable pointing to the location of the java executables so typing 'java' runs Java 8. JDK 11 does not do this by intent. You cannot run Java 11 and later from the command line but need some additional steps. Se my post here.

Running jars under OpenJDK 11

With Java 8 you could run a jar on a Windows PC by double clicking on it. This does not work with OpenJDK so as I want to be able to quickly run some utility B4J programs easily without packaging them this is what I did. 1) I installed OpenJDK in a convenient place, mine is in 'C:\jdk-11', and...

This works for running the jar - thank you.

Still trying to figure out why the standalone package crashes....

Johan Schoeman · Dec 5, 2021

Am I maybe missing a PackagerProperty in the B4J project that needs to include some missing module for the standalone package to work?
