[jetty-users] ClassCastException of Response to Response

[Jonathan Cohen <cohen@xxxxxxxxxx>]

I'd like to set the HttpOnly flag on a cookie, so I tried creating a 
org.eclipse.jetty.http.HttpCookie, but then I need to cast the 
HttpServletResponse that the doGet gets to a 
org.eclipse.jetty.server.Response so that I can call addCookie with that 
class of cookie.

    ((org.eclipse.jetty.server.Response) resp).addCookie(ck);

That gives me a ClassCastException, even though it looks like the object 
is the right class. I assumed it is because the ClassLoader at the  
server level is not the same as at the servlet, but when I tried setting 
parentLoaderPriority it didn't help.

<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>7.1.4.v20100610</version>
<configuration>
<webAppConfig>
<parentLoaderPriority>true</parentLoaderPriority>

I tried both true and false.

I have a workaround using reflection, but it is obviously not the right 
thing to do. What is the right way to call a method on a 
org.eclipse.jetty.server.Response?
