    java.lang.NoClassDefFoundError

    818240
      Hi all,

      I've been trying to install a java-based software on Ubuntu 10.10.

      Once I launch the code (./runHydra), I get this message and I don't know what to do...

      Traceback (innermost last):
      File "/opt/HYDRA/hydra/DataSelect.py", line 16, in ?

      Do you need other information to sort this out?

      Thanks,
