Using a current version of rJava, you can register the Java side objects
for serialization using .jcache().
E.g.,
m1 <- J48(Species ~ ., data = iris)
.jcache(m1$classifier)
then save/load will work as expected.
Eventually, the above may happen automagically.

Thanks, it works quite well in my MacOS.
Yet, in a linux machine (Fedora 9, R version 2.7.2, latest rJava and
RWeka versions has found in the berkeley server), sometimes the save
function produces a Segmentation fault. Since I am working with large
datasets (email filtering), I wonder if there is any
bug/limitation/problem of rJava/RWeka for large models (e.g. NaiveBayes
with more than 1000 inputs).
