server exception

Hi all,
when i tried to compile my java service iam getting some exception. can anybody please help me.
exception is
com.wm.app.b2b.server.ServiceException: com.wm.app.b2b.server.ServiceSetupException: ‘dutta.utils’ >> java.lang.UnsupportedClassVersionError: dutta/utils (Unsupported major.minor version 49.0)
my IS version is 6.1
Thanks
jay

i found the answer from the advantage site. The exception is beacuse of the difference in the JVM versions. The JVM version of my IS is different to that of the JVM used to compile my classes.
Thanks
Jay
