Just a correction - GWT uses UTF-8 and not UTF-16. Also, you *can* do String.getBytes() and similar hacks to convert from ISO-8859-1 (oracle) to UTF-8 -- but in my opinion it is best to store data in UTF-8 in the database.
In general, you need to revisit all interfaces where data exchange happens, and ensure that a) both systems are using same encoding or b) One system re-encodes the data appropriately. (a) is always better than (b). --Sri On 6 May 2010 22:53, David Given <[email protected]> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > On 06/05/10 16:08, undertow wrote: > > Thank you for confirming what i had suspected i would need to do.
