Hi Izabell, It sounds like maybe it was compiled with one version of java then you are trying to re-compile it with 1.4.2. I would run an 'ant full-clean' to remove all of the class files and start over. Here's a sequence of commands that's worked for me in the past:
from the kepler directory: ant fullclean ant ptolemy ant buildkarlib ant run-dev that should remove the class files for both kepler and ptII, recompile ptII, rebuild the kar files then run kepler. Let me know if that doesn't work. chad Izabell Caraconcea wrote: > Hi, > I'm not able to run Kepler on my machine, even if I have Java RE and SDK > 1.4.2_10. > I got an error message containing these lines: > <<Unable to start application...caused by > java.lang.UnsupportedClassVersionError: ptolemy/vergil/VergilApplication > (Unsupported major.minor version 49.0)>> > On the project's web site the requirement is to have JRE 1.4 (or later) > installed. > It seems that the version 1.4.2_10 is not enough and the above class was > complied with a newer version (1.5?) > So...what should I do? > > Thanks! > Izabell > > > ------------------------------------------------------------------------ > > _______________________________________________ > Kepler-users mailing list > Kepler-users at ecoinformatics.org > http://mercury.nceas.ucsb.edu/ecoinformatics/mailman/listinfo/kepler-users
