Hello,
I'm trying to implement a servlet layer filter to fake a PUT or a DELETE based on values passed in through the POST request. This is to deal with clients that can't handle PUTs or DELETEs like a FLEX client. When I add the filter to the web.xml, my create account POST request throws a Jersey exception complaining about parsing the request body. When I remove that filter, account creation works just fine. The response shows a IOException. I'm actually not performing any operations in the doFilter right now, I just wanted to hook up a dummy filter and see if my code still worked. Does anyone have any idea why the JAXB marshalling is failing in Jersey when there's a filter?
