I was expecting:
user.name=jantje
What am I doing wrong???
The source code of the totov.class:
import java.util.Properties;
public class totov {
/**
* @param args
*/
public static void main(String[] args) {
Properties systemProperties = System.getProperties();
systemProperties.list(System.out);
}
}
Same class, invoked from a Unix System Services shell does give the correct value.
Thanks for helping me out.
Jantje.
JZOS not setting user.name system property right
The JVM is responsible for setting these properties - the JZOS launcher really doesn't have control of them. It could be that the environment under which you invoked the "java" launcher from a USS shell is different and allows the JVM to set this property properly.
I'm sorry that I can't offer any help - you will have to open a PMR with IBM.
