Re: How to insert Chinese (big5) through JDBC?

Thank you very much. Kris Jurka.
I'm now understand !

I will change the connection bean. Add the line required there.

You mentioned client_encoding works for some clients. What are they?

Or can I change JDBC driver ? Where is the "set client_encoding" in JDBC ?

Best Regards,

Yes, I apologize for having steered you wrong. After some further
investigation, the approach I mentioned will work for other clients, but
not for JDBC. The postgresql JDBC driver does a SET client_encoding =
'UNICODE' when it first starts up which overwrites any default value
assigned to a user or database. The paradigm it seems to be working with
is that anything Java based should be working with Unicode data only, and
it will let the backend do the encoding conversion between Unicode and the
server encoding. This means you need to alter your code to convert from
Big5 to Unicode to work with this system although I'm not sure what the
best way to do this is.

You mentioned that this was a jsp application, what is the default
character encoding for the application server? Does adjusting that help?
