Starting with WebSphere Application Server Version 5, the Web container no longer automatically sets request and response encodings, and response content types. Programmers are expected to set these values using available methods in the Servlet 2.3 Specification or later. If programmers choose not to use the character encoding methods, they can specify the autoRequestEncoding and autoResponseEncoding extensions, which enable the application server to set the encoding values and content type.
The values of the autoRequestEncoding and autoResponseEncoding extensions are either true or false. The default value for both extensions is false. If the value is false for both autoRequestEncoding and autoResponseEncoding , then the request and response character encoding is set to the Servlet 2.3 Specification default, which is ISO-8859-1. Also, if the value is set to false for a response, the Web container cannot set a response content type.
Use an assembly tool to change the default values for the autoRequestEncoding and autoResponseEncoding extensions.
Review the autoRequestEncoding and autoResponseEncoding encoding examples for a description of Web container behavior when these values are set to true.
