tcp-outbound-gateway - failed to send Message to channel

[thehin]

Hello,

I am trying to follow the tcp sample off GitHub (http://git.springsource.org/spring-i...ver/readme.txt) and I am getting an error when trying to send a message to a tcp server. The error I get is "failed to send Message to channel." Below is my xml configuration. What am I doing wrong :-(. I am using Spring Integration 2.0.1 RELEASE.
