AXIS Receiver Adapter - No response (java.lang.NullPointerException)

[former_member328642]

Hi,

Can someone please help me for the below issue?

We are using AXIS Receiver adapter to send a request but we couldn't see the response in SAP PO system. Below is the error message in Sender channel (File & async-sync bridge). We don't see any error in the Axis receiver channel (Receiver 3rd party team also confirmed that the request is successfully processed and response is sent).

Transmitting the message using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.lang.NullPointerException: while trying to read the field 'value' of a null object loaded from local variable 'original'

The network connectivity is already verified...Actually, the same scenario worked in the DEV system but not in QA (the main difference - Dev is single server; QA - 2 app servers with a cluster).

I also tried XPI inspector but couldn't get any clue. Below are few messages from XPI log.

Module Exception 'com.sap.aii.af.lib.mp.module.ModuleException: Sender Channel 'CC_Sender_FILE_xxxxxxxx' : Catching exception calling messaging system' found, cause: com.sap.engine.interfaces.messaging.api.exception.MessagingExcep java.lang.NullPointerException: while trying to read the field 'value' of a null object loaded from local variable 'original'

Couldn''t deliver sync response message to XI RA, due to java.lang.NullPointerException: while trying to read the field 'value' of a null object loaded from local variable 'original'

kishan.pannem could you please share the screenshot of the module tab of that channel?

Thank you Michal. Here are the details of Axis receiver channel - module tab.

(Receiver system requires Web Services Security (PasswordText) so we chose Axis; Sender channel is FILE (Async-Sync Bridge)).

Hello Kishan,

Did you find an answer to this? I'm facing the same issue, exact same scenario with WS Security and same error code. No clue in XPI Inspector.

Hi Pablo,

Yes. Please refer the SAP Note# 2850724.

The reason it worked in DEV but not in QA (in our case) was because DEV system is at a higher patch level and QA is at patch level 0. So, the issue was resolved after upgrading the patch in QA system.

Please check the note and also patch level in your PI/PO system and let me know if you still have any issues.

Thanks,

Jai Kishan.
