http://java.sun.com/javaee/5/docs/api/javax/servlet/http/HttpServletResponse.html#sendRedirect%28java.lang.String%29

Throws IllegalStateException if the response was committed or if a 
partial URL is given and cannot be converted into a valid URL.

I guess that a redirect to the login page is made after writing content 
to the response body.

http://java.sun.com/j2se/1.5.0/docs/api/java/lang/StackTraceElement.html#toString%28%29

"Unknown Source" means that those classes were not compiled with 
debugging information. This is not a problem.

Hope this helps,
