I have this code:

....

   try {               

            conn = ((Session) this.getEntityManager().getDelegate()).connection();

        cs = conn.prepareStatement( "insert into acdsys.Vmiseam values (null, 4, sysdate, 28, 31, ?,'D222','A333')" );

            cs.setString(1, test2); 

            cs.executeUpdate();

    ....

i see in the debugger, that the varable has a right value! (a mix of cyrillic with german-umlaute "Ö","Ä" etc)

If i set the Unicode directly in my Oracle-database, e.g.:

update acdsys.Vmiseam set v1 = UNISTR('\041F\0435\0442\044F') where id = 32

it is shown absolutely correct in my web-application! But the insert (see upper) losts the non-standard characters! (= can't write it as unicode properly!)

I've tried things like this:

                  Properties connProps = conn.getClientInfo();
                  connProps.setProperty("oracle.jdbc.defaultNChar","true");
                  conn.setClientInfo(connProps);

but they doesn't work: :-(

Who can help my please with this issue?
