Liveconnect: java.io.InputStream from javascript string

Hi

Is it possible to get javascript string (containing binary data) as a
java.io.InputStream descendant?
I tried to do this:
var bytes = new java.lang.String(jsString).getBytes();
var byteIn = new java.io.ByteArrayInput(bytes);
but it works incorrectly.

P.S. And also is ther a way to convert java.io.OuputStream back to
javascript string?

Thanks,
telega
