[mule-user] script component binding not working in 3.2.0
Ken LAI
However, it throws an exception the interface not visible in the class
loader. Is it a bug and anything I miss out?

<description>
This example demonstrates how to orchestrate message flows
using bindings. The example calls out to two
different services and passes the results on to the outbound router.

Hi Ken,
Where is your custom class located physically?
Andrew
Ken LAI
class file of component binding interface require to put in
MULE_HOME/lib instead?
Thanks,

directory. That means I have to put it aside. Is there any alternate
way to maintain it inside the apps?

I think script component is not executing with the right application classloader. In that case its a bug, please file a jira.
