Error message on running Barracuda App in Enhydra5.1

Hi,

I managed to compile a barracuda application, using enhydra5.1 (this
appliation working with enhydra5.0), but when I run the application, and
try to access it, I get the following error message:

Unhandled error! You might want to consider having an error page to report
such errors more gracefully java.lang.NoClassDefFoundError:
