Flex - Java communication problem.

Hello,
Im trying to fix a webapp, which i didnt write myself, i was told everything used to work fine before
Only thing i can think of that might have changed, is a server restart.

I have no experience with Flex and BlazeDS, but i do know some Java
it seems to be configured ok. When i click the send button on the webapp, my eclipse console tells me

INFO: Channel endpoint my-amf received request.

1) So the communication must be working right?
2) How do i tell it what to do from there?
3) How do i get the string that the app sends me?

forgive me if my questions are stupid, but ive searched all over the net and cant figure out whats wrong. If you need to see settings of a certain xml file please tell me and i will post.

Thanks in advance

what is the issue? what are you trying to fix???

The Flex app(an order form) is supposed to send data to the java app, so the java app can write the order to the database.

The person who made it does not work here anymore, and cant be reached, so i really have no one to ask.
I think the connection is allright, i just have no idea how i tell it to get the string and which method to use.

EDIT: the issue is that orders dont show up in database

Are you using any framework like cairngom or something?
Try to debug from flex to java..
