Flash remoting returns HTTP code 200, classified as error

Question

Hi,
Our problem is with an older application, originally created with Flash MX2004.  It is an application which schools use and communicates with our Java services.  We've always had some issues with remoting errors but it seems this past school year has been much worse.
The issue does not happen all the time and the schools have reported it as  being sporadic.  We have been working with the schools to see if we can track  down the issue and what we’ve found is that the data is coming back to the  application correctly but it is somehow interpreted as an error within the  Macromedia classes.  Currently, the schools are reporting that their labs which have IE8 seem to be getting the issue while it is OK in the labs which still run IE7.
Has anyone heard of a similar issue in that they can point us in the right direction to get this resolved?

Answer 1

to add to the above details, when i look at the headers of the response object i see the following:
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
X-Powered-By: Servlet 2.4; JBoss-4.2.2.GA (build: SVNTag=JBoss_4_2_2_GA date=200710221139)/Tomcat-5.5
Content-Type: application/x-amf
Content-Length: 18893
Date: Wed, 07 Oct 2009 15:52:24 GMT
Cache-Control: no-cache
but when i look at the properties of the Connection object i see:
contentType: application/x-fcs
Is it normal for it to be different like this?
