nullPointerException in tWebServiceInput while running in ESB

_AnonymousUser — Sat, 16 Nov 2024 12:06:36 GMT

Hi
I am working with Talend's tWebServiceInput component. But for some reasons its not working in TESB.
I am working with test web service
"http://www.deeptraining.com/webservices/weather.asmx?WSDL"
its gives me desired result in Talend open studio.
But when I exported job as osgi bundle and run it in ESB
I got following exception

karaf@trun> Exception in component tWebServiceInput_1
java.lang.NullPointerException

Thank you,
Regards

hi
I have to call a websercice,
If I use the component tWebService I have problems with permissions, but reading the forums it looks like a bug.
then,
I'm trying to use the tWebSeviceInput, but I can not use it properly.
returns me this exception:

Exception in component tWebServiceInput_1
java.lang.NullPointerException
at org.talend.DynamicInvoker.invokeMethod(DynamicInvoker.java:241)
at org.talend.DynamicInvoker.main(DynamicInvoker.java:190)

at interfacce_pragma.import_anagrafiche_bkd_0_1.Import_Anagrafiche_BKD.main(Import_Anagrafiche_BKD.java:3728)

Can you tell me how to properly configure the two components?
and in particular how to pass parameters to tWebServiceInput?
Using the components in this way:
tFixedFlowInput -----> tWebService ----> logRow
tWebServiceInput -----> logRow

Thank you very much.

Hello,

I get exactly the same error message when running my Job with karaf:
karaf@trun> Exception in component tWebServiceInput_1
java.lang.NullPointerException
at org.talend.DynamicInvoker.selectService(DynamicInvoker.java:388)
at org.talend.DynamicInvoker.invokeMethod(DynamicInvoker.java:226)
at org.talend.DynamicInvoker.main(DynamicInvoker.java:190)
at org.talend.DynamicInvoker.main(DynamicInvoker.java:131)
But when I start the Job in Talend Open Studio it works perfectly. I don't use the "Advanced Mode" of the tWebServiceInput component.

Try and use https://help.talend.com/search/all?query=tESBConsumer&content-lang=en instead

Thanks for your reply. With the component tWebServiceInput i was able to specify the method Name dynamically... This isn't possible with tESBConsumer, isn't it?

Not exactly sure what you mean with method. You referring to the WDSL's port operation?
