Hi,
I have a development environment, which runs on Java 1.8. But my target
environment runs on Java 1.7. Now I try to deploy my application but it
fails with:
java.lang.UnsupportedClassVersionError:
com/webobjects/foundation/NSArray : Unsupported major.minor version 52.0
It seems, that the frameworks, which are bundled with my application are
compiled with 1.8. I have tried some settings:
1. On the project build.xml set source/target to 1.7 on the wocompile
task
2. on Eclipse Ant Runtime preferences I have set the properties
ant.build.javac.source and ant.build.javac.target to 1.7
3. I have recreated the WonderSource with the same properties on the
commandline
Nothing will work, always I get the same error. What I can do?
Thanks a lot
André
