When working with Java servlets, the Java Servlet Specification is the primary reference, but the servlet spec itself relies on older specifications such as HTTP for its foundation. Why does everything have to be this way?Įverything covered in this page comes down to practical interpretation of a number of specifications.

For JSP pages in standard syntax the default response charset is the usual ISO-8859-1, but for the ones in XML syntax it is UTF-8. See chapter "JSP.4.2 Response Character Encoding". The request character encoding handling is the same, but response character encoding behaves a bit differently. The behaviour of JSP pages is further specified by the JSP specification. The above general rules apply to Servlets. References: HTTP 1.1 Specification, Section 3.7.1 An example of such a header is Content-Type: text/html charset=ISO-8859-1 which explicitly states that the default (ISO-8859-1) is being used. The character encoding for the body of an HTTP message (request or response) is specified in the Content-Type header field. If a character encoding is not specified, the Servlet specification requires that an encoding of ISO-8859-1 is used.
