[Flex] RTMP-Server failed to start up

Hi All,

I am trying to run Flex Data Services as a Tomcat 5.5.17 Server under Eclipse 3.1.2 WTP. When I start the server in Eclipse I get the following error:

[Flex] RTMP-Server failed to start up: java.net.BindException: Address already in use: bind
flex.messaging.endpoints.rtmp.RTMPException: The RTMP server has encountered a fatal exception starting up: Address already in use: bind
at flex.messaging.endpoints.rtmp.BaseNIORTMPServer.run(BaseNIORTMPServer.java:310)
at java.lang.Thread.run()V(Unknown Source)

I have tried changing the services-config.xml RTMPChange port to about 10 different ports, and this hasn't resolved the issue:

<channel-definition id="my-rtmp" class="mx.messaging.channels.RTMPChannel">
<endpoint uri="rtmp://{server.name}:9876" class="flex.messaging.endpoints.RTMPEndpoint"/>

When I run Tomcat outside of the Eclipse, this web application starts fine and no errors are logged.

Other environment details are: Windows XP, JDK 1.4.2_10
