Error happens when undeploying SwitchYard application with transformers
- I’m having trouble with undeploying SwitchYard applications with pending requests and their response transformations.
- It seems that after the JBoss FSW waits for all requests to be completed and undeploys the applications, all response transformations are skipped.
As an example, I have two simple SwitchYard applications: Hello and World.
- The Hello application communicates with the World application using a SCA Binding.
- The World application contains a bean that returns a
WorldOutputobject, but since the SCA Binding returns a
String, I created the
SCATransformerclass to transform the response into a
- All requests to the World application will take longer than 15 seconds, because it contains a
- After Hello application received a request and called the World application, I tried to undeploy the World application and the JBoss FSW waited for 30 seconds for all pending requests to be completed.
Afterwards, the application was undeployed and I got this exception:
org.switchyard.HandlerException: SWITCHYARD014011: Transformations not applied. Required payload type of 'java:java.lang.String'. Actual payload type is 'java:com.example.switchyard.interfaces.WorldOutput'. You must define and register a Transformer to transform between these types.
The Hello application received a response that was not transformed.
- Does this exception make sense or is it a bug? If it’s not a bug, is there any workaround?
