After experiencing something similar, I read somewhere
that CallableStatement's shouldn't be used pre-8.0. I
think someone posted on a message board or something.
I changed all my java code to call my functions as
PreparedStatements:
ps = con.prepareStatement("select myFunction(?,?)")
ps.setBoolean(1, true);
ps.setInt(2, 198);
etc.
And it worked fine from there on.
