You can do this by changing your code from: VisADForm().save(filename,fselect,1) to: VisADForm(1).save(filename,fselect,1) (I think that's the way to pass 'true' to the constructor ... I'm still learning this Jython stuff) This will use VisAD's own binary format, rather than Java's serialization. The VisAD-specific binary file classes are slower than Java's serialization code, but are guaranteed to be backward compatible even if the file format changes in the future.
