Message: 108362 BY: arton Tajima (arton) DATE: 2012-12-01 01:03 SUBJECT: RE: Bad version number in .class file error   Hi, What is the exact version of the classes in your Jar? I wonder if you may extract classes from jar and "javap -v *.class|grep major" and report it. cf) 51: JDK1.7 50: JDK1.6 49: JDK1.5 I've also checked Rjb gem, it includes class file with major version 50 (means JDK1.6, not JDK1.7). Regards.
