This sounds like a worth candidate for an enhancement
request, I'll log one
for you on your behalf.
As a work around for now, can you convert your java.sql.Clob
to a char[]?
This should be returned as a String on the client. As for
java.sql.Blob,
can you convert that to a byte[]? This should be returned as
a flash.utils.ByteArray
on the client.
