Java mapping Issue 3: Java null pointer exception

[Former Member]

Dear All,

We have a Java mapping used for mapping complex structure. Its BPM to SFDC scenario. Java mapping working fine its processing 200+ messages everyday but 1 or 2 messages fails everyday with below error.

Java mapping code attached.

What its failing ? Same Java mapping works fine for 200+ messages but why few messages fails?

Hi Avinash,

I think your code is right. Have you checked the payload of the erroneous cases?, you should take the payload and to compare it with a ok case. I think the XML structure could be different.

Hello Inaki,

I have tested the payload in ESR, it works fine.

at runtime, when message fails with above mentioned error, message status will be cancelled, corrresponding BPM instance will be at suspended status. If I resume the BPM then a new set of messages will be created and successful.

Same payload fails and gets successful. its pretty strange.

Let me know if you any comments else I will ignore this error.

Hi Avinash,

The null variable newChild is going to exist in the w3c dom parsing code so there is some issue happening within the imported libraries.  I would suggest taking one of the failed messages and using the stack trace as the output when the exceptions occur so you can see where exactly the failure is happening.

That doesn't make any sense that running it in the ESR works for the same failed message unless there are some memory issues going on when the message is transformed.

Hi Avinash,

I couldnt find the variable "newChild" in the java code. Is there any other code too using newChild variable.
