i don't know which part causes your problem.
you have to make sure everything running correctly by testing.
1. web service and database
try to type the url of your webservice in browser, and you will see the webservice page. And you can try to enter some info to invoke the webservice, ensure both web service and dabase have no problem.
2. red5 server and flex
did you compile the red5 source code and my code? don't forget to modify the xml configuration of Ant to compile them together.
After compilation, chage the correct url of red5 in flex code:
. AccountService.as -- private var wsdl:String = "
http://192.168.0.88/XyzTalk/AccountWS.asmx?WSDL";
. HallService.as -- private var strCon:String = "rtmp://192.168.0.88/xyzTalk/hall";
