I am calling a rest service which is failing at their end so how can I handle it in my model . As when the service fails my model is getting interrupted.

Also in their any way for converting model from interrupted state to Active.

Hi,
you need to add onException block in your defaultCamelContext

<camelContext ...>
<onException>
<exception>java.lang.RuntimeException</exception>
<handled><constant>true</constant></handled>
</onException>
...
</camelContext>

This will prevent the current transaction to rollback.
then you can use event handler mechanism to catch the error at Process level.

Regards

Thanks Ashish,

I understood your example. But you showing Error to user and If user completes the activity the process will end.

But I don't want the process should end. The person should contact administrator, once the admin fix the web service issues the person should resubmit the web service data back to service ... get success and go for next activity in process.
