Hi all,
I have a class mediator which calls a REST service and parses the output
and injects it to the soap body of the messageContext. This class mediator
is in the main sequence and is invoked periodically by a task scheduler.
When i try to achieve this task i get the following error. It used to work
well before trying to inject it to the messageContext and i can't seem to
find the error now. Here's the stack trace.
ERROR - JobRunShell Job synapse.simple.quartz.TriggerSequence threw an
unhandled Exception:
