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

Hi Patil,

Please find a attached sample model which shows how the error is handled. The model shows how the SQL Application Activity is aborted on error(e.g "org.springframework.jdbc.BadSqlGrammarException" caused due to use of invalid table name)and the error is handled.

You can refer below documentation how to add "Error Boundary Event"

http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.stardust.docs.analyst%2Fhtml%2Fhandbooks%2Fmodelling_analyst%2Fpep-events.htm&resultof=%22boundary%22%20%22boundari%22%20%22event%22%20

See section Error Boundary Event - Implementation

Best Regards,
Ashish

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 SQL issue the person should resubmit the data back to SQL... get success and go for next activity in process.
