Try Catch inside of a Try

Is there a way to embed a “try catch” within a “try”?

I have a flow service with a main “try catch” statement. Within the main “try” I am implementing “pub.client:smtp”. Currently, if the email server is down, it results in an error in the flow service, and the flow service exits. However, in the event of an error related to “pub.client:smtp”, I just want the flow service to move on with the rest of the code inside of the “try”.

I’ve tried embedding another “try catch” inside of the main “try” statement; however it doesn’t appear to work. I’m on IS version 10.1.

What would be the best way to implement this? Thanks.

-main - success (outer)
--try - failure
---a=1
---main - success (inner)
----try - failure
-----smtp invoke
----catch - done
-----log error or do nothing
---b=1
--catch - done
---log error or do nothing

Hi Mahesh,

Thanks for your reply. The problem appears resolved now.

Initially I tried with the inner “try” set to failure and the inner “catch” set to done; however, when the smtp service threw the error, the flow service went to exit without completing.

But setting the inner “try” to done appeared to do the trick. In this instance, I did not even need the inner “catch”. When the smtp service threw the error, the flow service moved on and completed.

Thanks,

Ken

How can I get the same functionality using the new TRY_CATCH and TRY-FINALLY available on the new Service Designer ?

Hi All,

I have below scenario for try/catch, could you please me on understanding?

1.) Seq–Main (exit on - Success)
Seq–Try (exit on - Success)
Seq–Catch(exit on - Done)

2.) Seq–Main (exit on - Success)
Seq–Try (exit on - Success)
Seq–Catch(exit on - Done)
Seq–Finally(exit on - Done)

3.) 2.) Seq–Main (exit on - Success)
Seq–Try (exit on - Success)
Seq–Catch(exit on - Done)
Seq–Finally(exit on - Success)

in above scenario catch and finally will execute or not.
