Hello,

Can someone help me? I'm trying to install bioweka but when I execute bioweka.sh and open the explorer I get the following stacktrace in my terminal

I'm using bioweka 0.7 and weka 3.4.4

regards,
Bram

Did you tried another (older) Weka version?

[Bram Gadeyne]

Yes I've tries these weka versions:
3.0.6
3.3.6
3.4.4
3.6.2

None of these seem to work. It's always the same problem. Could it be something with my Java version? I'm using Java 6.20 (on ubuntu linux)

I'm sorry. I have no glue.

One option might be to debug the project within Eclipse and trace the error.
