Re: [Dev] [ESB] Class mediator - task scheduler error
Hi Dushan, Thanks for the suggestions. In fact i did remote debug the code and couldn't yet identify what's causing the issue. I extracted a fresh ESB and now the class mediator is working when it's put in to the main sequence and invoked from a scheduled task. The same code is working as expected in this case. I think i might have messed with the synapse configuration somehow. This class mediator calls upon a REST api via HTTP POST and parses the xml returned as the result. Then the contents of this xml is inserted to the soap body of the MessageContext and sent to an aggregator mediator which will aggregate similar soap messages. More info about the project can be found at [1] in the architecture@. Thanks.

[Dev] [ESB] Class mediator - task scheduler error
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: org.apache.synapse.SynapseException: Error occured in the mediation of the class mediator at org.apache.synapse.mediators.ext.ClassMediator.mediate(ClassMediator.java:82) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:47) at org.apache.synapse.mediators.filters.InMediator.mediate(InMediator.java:61) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) at org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:47) at org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:131) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.injectMessage(Axis2SynapseEnvironment.java:228) at org.apache.synapse.startup.tasks.MessageInjector.execute(MessageInjector.java:315) at org.apache.synapse.startup.quartz.SimpleQuartzJob.execute(SimpleQuartzJob.java:88) at org.quartz.core.JobRunShell.run(JobRunShell.java:213) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:557) Caused by: java.lang.NullPointerException at org.wso2.cloud.monitor.agent.esb.mediators.icinga.IcingaAdapter.mediate(IcingaAdapter.java:89) at org.apache.synapse.mediators.ext.ClassMediator.mediate(ClassMediator.java:78) ... 11 more [2014-05-30 15:16:12,137] ERROR - ErrorLogger Job (synapse.simple.quartz.TriggerSequence threw an exception. org.quartz.SchedulerException: Job threw an unhandled exception.
