That sounds strange - what versions are you using of SwitchYard / Wildfly or (Fuse / EAP)?
Well i downloaded switchyard release for wildfly @ Release 2.1.0.Final · jboss-switchyard/switchyard · GitHub and then i build this with mvn install -DskipTests=true and then after i startedup the server and tried to deploy my switchyard application.
Not sure what version of wildfly we are using here.
My bad, i had a system property in switchyard which was not configured in wildfly.
Now it's working.
May there could be an error in the logs so that we know that something went wrong...
