Major issues with jsp:param in jsp:include and jsp:forward





------- Additional Comments From ben_kelley@ubsw.com  2003-10-23 01:30 -------
I agree that passing non-ISO-8859-1 characters (or whatever your platform 
default is) via <jsp:param> is broken in 4.1.27.

A suggested work-around:

While this work-around won't be suitable for all applications, it is handy 
where an included page (or a page that is always the target of a forward) 
wants to receive characters that would otherwise not work.

Basically encode the value of the parameter into something that can be 
represented in ISO-8859-1 before passing it to <jsp:param>, and then do the 
reverse encoding in the called page. Using Java 1.4's URLEncoder.encode
(string, "UTF-8") before giving the string to <jsp:param> is one such encoding 
that does this.

This causes:
[non ISO-8859-1 suitable string]
  (encode using URLEncoder.encode(string, "UTF-8"))
[string that can be represented in ISO-8859-1]
  (pass to <jsp:include> or <jsp:forward> via <jsp:param>)
  (Tomcat calls URLEncoder.encode(string))
  (Tomcat calls the included or forwarded page)
  (Tomcat calls URLEncoder.decode(string))
[string that can be represented in ISO-8859-1]
  (decode using URLDecoder.decode(string, "UTF-8"))
[original string]
