GBK Encoding Not Supported in Websphere

[f1shiva]

Hi Guys,
Am encountering "TransformerException: Invalid encoding name 'GBK'.", when i try to use GBK as my XML encoding <BR>
in Websphere Application Server. Version is 4.0. Sun Solaris 5.9 is the OS. JDK 1.3
i have configure the file.encoding ="GBK" for the JVM. also in my servlet response
am setting the charset as GBK in the content type.
if the change the encoding as GB2312 in the XML it works fine. But Still i maintain GBK in the other places like File.Encoding="GBK" and charset in the Servlet response as GBK.
Am creating the XML on the fly and using XSL Transformer am creating the HTML Page.
Please find the Exception Below.

javax.xml.transform.TransformerException: Invalid encoding name "GBK".

It appears as if GBK is only supported by SDK version 1.4 and above.

http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html

(search the page for GBK and you see it is only supported by java.nio streams, which were introduced in SDK1.4)

Having said that actually, this doc :

http://java.sun.com/j2se/1.3/docs/guide/intl/encoding.doc.html

seems to say that GBK is supported in an extension file i18n.jar - have you got that file in your JAVA_HOME directory ?

Even if it is there, you may get support for the java.lang classes, but not in IO packages and those reliant on IO such as servlet packages.
Also, the error message seems to indicate that GBK is not supported.

Maybe you should upgrade your J2EE server and SDK versions ...
