Re: Properties init: Could not determine current working directory.

Hi David, this is my check list when I got problems with Java:

Make sure that *PUBLIC has at least *RX authority to the following
directory paths:
/QIBM/ProdData/OS400/Java400/
/QIBM/ProdData/OS400/Java400/ext
/QIBM/ProdData/OS400/Java400/jdk/lib/
/QIBM/ProdData/OS400/Java400/jdk/lib/ext/
/QIBM/ProdData/Java400/jdk11/lib/ext/
/QIBM/UserData/Java400/ext/

QIBM_MULTI_THREADED = 'Y'

/QOpenSys/QIBM/ProdData/JavaVM/jdk17/64bit/conf/security/java.policy

Is there a possibility that the JVM was already in error before the Java
class was executed in your RPG?

HTH
