Webservice action block-null pointer exception

[steve_stubbs]

Hi Experts,

I am calling the below service from web-service action block in SAP MII 15.4:

https://<server-port>/manufacturing-papiservices/SplitSerializeServiceWSService?wsdl

When I run transaction from the workbench, I get this error.

• [ERROR] [Event_Logger_Error]UserEvent : Nutek Serialize papi exception java.lang.NullPointerException

The catch action block is not giving any different error.

Can you please point to area of issue?

Thanks in advance.

Regards,

Neha

HI Neha,

The error means that you either did NOT assign an element value that was required, or you assigned a value that referenced a non-existent object in ME.

Which WS method are you calling from the web service?

The error shows as coming from an Event Logger. Please share a screenshot of your transaction.

Hi Neha,

You are assigning a Local XML node to the Web Service Request. The local node name is 'requests' and this is replacing the node name 'ns1.Requests', which is a different xml node structure and elements; and this could be causing the errors. Where did you get the structure Local.SerializeXML property?

Hi Steve,

Un-checking the Execute the Web Service action helped to get input XML. I mapped value to it and its working fine.

For the production environment, Serliaze PAPI is giving an error. After checking all possibilities I want to try the web service action block as the last option and it works. The strange part is PAPI doesn't give errors in other environments.

Thank you for your help.

Hi Steve,

Thank you for your reply.

I tried a few options to map XML but had no luck.

Is it possible to get input XML for webservice action block as we get in PAPI?

Thanks in advance.

Hi Neha,

You can get the web service request xml by creating the web service in a transaction, un-checking the Execute the Web Service action, and tracing the Web Service request xml. However you will likely run into namespace issues depending on how you do this.

Why not just execute the Serialize PAPI directly in MII?

Hi Steve and Mike,

Thanks for the quick reply.

I am using the method "serliazesfcs" from the above webservice. I checked input getting mapped to action block and all inputs are present in SAP ME.

Here is mapping in transaction.
