Best practice for retry on fail

[mahmut]

Hi,

I have to develop some workflows using activiti and some of the tasks have to make soap calls.
If a soap call fails, because e.g. the soap server just not respondig, the task should retry the call after a predefined time.
What is the best practice for building "retrying tasks"?

Thanks.

Hi,

You could implement error handling logic that connects to the same service task in case an exception is thrown.
When asynchronous execution is also possible you could use the async="true" attribute. Then the job handler will retry to a maximum of 3 times.

Best regards,

On asynchronous execution the job is executed immediately one after another, so if the soap service is offline even for a few seconds, the job will fail.
Therefore I think an error handling logic will be the better choice…

Thanks.
