Increase heap size in java for weka

Question

I\'m trying to increase the heap size in java for weka which keeps crashing. I used the suggested line:

> java -Xmx500m -classpath

but

Answer 1

You need to specify a classpath after -classpath, similar to the PATH env variable you need to specify the path where Java can find the classes.

The -Xmx500m setting looks fine, except that I would suggest to use 512m.
