Manage Errors & on component error

Anonymous — Tue, 28 Jul 2015 09:14:44 GMT

With the tHTML component I have the following error:

Exception in component tHTMLInput_2
java.lang.NullPointerException
    at pmi.getcurrency_bnh_html_0_1.GetCurrency_BNH_HTML.tHTMLInput_2Process(GetCurrency_BNH_HTML.java:1478)
    at pmi.getcurrency_bnh_html_0_1.GetCurrency_BNH_HTML.tSleep_1Process(GetCurrency_BNH_HTML.java:2076)
    at pmi.getcurrency_bnh_html_0_1.GetCurrency_BNH_HTML.runJobInTOS(GetCurrency_BNH_HTML.java:2338)
    at pmi.getcurrency_bnh_html_0_1.GetCurrency_BNH_HTML.main(GetCurrency_BNH_HTML.java:2159)

Is it possible to create a loop on the compoent until It is success?

Something like: on component error retry or loop

Any idea?

Thanks

Didier

hi,
not sure about your expectation but call your job with tRunJob , uncheck die on child job & use tloop to manage loop (risk of infinitive loop )
So having a java null pointer exception is an expected behavior ???

Hi Didier,

Have you checked component TalendHelpCenter:tInfiniteLoop which allows you to to execute a task or a Job automatically, based on a loop.
The workflow should be:tInfiniteLoop-->iterate-->tHTMLInput-->tOutput-->OnsubjobOk-->tDie(to stop an infinite loop job).
More information about your job requirement will helpful for us to give you more accurate answers.

Best regards
Sabrina

Below my job:

I have the error on the tHTMLinput component accessing to the web site. Sometime it wirks sometimes it doesn't work!

So that means to implement something like:

is it correct?,

Thanks

logicaly seems like ok (i' haven't reproduced your process

did you test when page is not reached ? (not sure about kind of error : a java exception that 'll end application or not)

Bad news!!

With the tInfiniteLoop and tdie components my two tables are not updated

If I remove these components, it works!

Any ideas???
