Spring BlazeDS flex.messaging.endpoints.AMFEndpoint

Question

I have been struggling with this today for quite a while, removing everything but the default channels just to get it going. I have resolved all of my library issues (I hope) and now am getting the error below. I have also included my config files in case anyone can take a look at this. Thanks!!!

Answer 1

Do you have a...

<flex:message-broker />

...entry in any of your spring-context-configuration.xml files? I had a similar error, if not the same, until i added it...

Answer 2

Do you have xalan.jar in your WEB-INF/lib folder..issue is related to a missing jar file..
