I'm using Resin 2.1.17 on Linux and getting two problems.

I created javax.servlet.Filter implement, it passed wrapped respose object
to chain.doFilter();
Like this:
	public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain)
			throws IOException, ServletException {
		HttpServletResponseWrapper response2 =
			new HttpServletResponseWrapper((HttpServletResponse)
response);

		chain.doFilter(request, response2);
	}

This is a simple JSP file which has an error.
-- test.jsp ---
	<%@ page contentType="text/html" errorPage="/e1.jsp" %>
	<html>
		<body>
		<%= a %>
		</body>
	</html>


Problems are:
(1) When errorPage is the jsp file, I expects errorP
age output, but I got 404 not found page.

(2) When errorPage is the static html file, I got exception:
[2006/06/01 17:39:01] http://localhost/test/filter/a3.jsp: tried to write
content (char=`o') beyond content-length (42).
java.lang.IllegalStateException: http://localhost/test/filter/a3.jsp: tried
to write content (char=`o') beyond content-length (42).
