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

Omit the -classpath option. Use just -Xmx500m option.

So, instead of just:

java weka.core.Instances data/soybean.arff

you do:

java -Xmx500m weka.core.Instances data/soybean.arff

If you run weka via some script (RunWeka.bat for example), then you need to modify that script (with some text editor like notepad).
