I am trying to support a Java Java application that runs autonomously using the built-in jetty using Java 7 and Jetty 9.1.3. Everything works except for all links on one of the JSP pages. Each link on this page should receive a png file or a text file and display it under the link. When launched via Netbeans, each link simply hangs when clicked, and the console gives the following errors:

I did some research and found that this is often (or always) due to the fact that the shape is large for the berth defaults. A proposal was made to override the default values by creating an xml file called jetty-web.xml and placing it in the web / WEB-INF folder. Here is my newly created jetty-web.xml:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Configure PUBLIC "-//Eclipse//DTD Configure//EN" "http://jetty.eclipse.org/configure.dtd"> <Configure id="WebAppContext" class="org.eclipse.jetty.webapp.WebAppContext"> <Set name="maxFormContentSize">600000</Set> <Set name="maxFormKeys">20000</Set> </Configure>
I rebuilt the web application with this file in place and this did not fix the problem. I tried using large numbers, but it seems to have no effect. I'm not familiar enough with the pier, or even the basic way that the built-in pier interacts with java to know what to do next.
I would be happy to post any code from a violating JSP page or supporting Java code that handles requests, but I thought there might be enough console errors for now. Thanks so much for any help.
