Mark Walter skrev:
I'm trying to run a java class on my 400. But I'm getting an UnsupportedClassVersionError. I compiled the class in Netbeans with version 1.4.2. Which is what java -version shows in QSH on the iSeries.
If I try to do a JAVAP -Verbose on the class, it returns major and minor versions of both 0. Is there any way to debug this error further?
Some ideas:
Run javap on your pc against the java class file
Still returns major 0 minor 0
Double check that the file was transferred in binary mode if using ftp.
Dropped into iNav from my PC/
Ensure you don't have a JAVA_HOME variable set.
Not sure where to set this, but there is no environment variable as such.
Force the java version with "java -Djava.version=1.4 MyClass"
Same error.
Use "java -verbose MyClass" to see when the class breaks.
Here is where it fails:
