UnsupportedClassVersionError

Trying to install JOPR Agent on another staging server, I'm getting this UnsupportedClassVersionError:

D:\jopr-agent-2.1.0.GA\bin>rhq-agent.bat install

Any suggestions?

Thanks,

Version 49.0 should be Java5, which is what Jopr needs (as minimum jdk version) - did you try with Java 1.4 ?

Yes, I orginally tried with Java 4. But then I installed 5 and tried again. But apparently I needed to wait, or to close the DOS windown and open an new one. In any case, I tried it again, and it works now.

Thank you!
