Error: java.lang.NullPointerException

[Former Member]

Hi,

In my File - RFC - File scenario (PI 7.1), i am facing the error in the communication channel

File processing failed with java.lang.NullPointerException

But in SXMB_MONI it the status shows Processed Successfully.

From File to RFc it displays all the details like Sender Namespace, Sender Interface, Receiver component etc.

RFC to File it doesn't display any details other than Message ID.

The following steps are executed in RFc to File message:

Inbound Message ( CENTRAL )

XML Validation Inbound Channel Response

Request Message Mapping

XML Validation Outbound Channel Response

these steps also contain the output file format in xml structure:

<?xml version="1.0" encoding="UTF-8" ?>

- <ns1:MT_LOTUSNOTES_UNIFORM_FILE_RESP xmlns:ns1="http://lotusnotes.uniform.com">

- <ITAB_OUT>

- <item>

<STR>20000000|3022|-10.25|09.11.2009|Testing 1111|</STR>

</item>

</item>

</ITAB_OUT>

</ns1:MT_LOTUSNOTES_UNIFORM_FILE_RESP>

pls let me know how to solve this error

Hi,

First stop the channel in runtime workbench and then start it again.

Having the callstack for the NullPointerException would help ! Have you been able to find it somewhere ?

[Former Member]

Hi ,

could anybody please give some solutions to this error. i m not able to solve it.

I have a query. in the message mapping of File to RFC i have disabled some fields of RFC since it is not mandatory.

Is the problem b'cos of this. if so, i tried passing constant to this disabled fields and still the error exist.

Please help.

Hi,

>>file>RFC>File

Are you using BPM or responseonewasy bean??

See whether all configurations were done correctly or not.. Check these wiki page

Hi ,

I am doing it without BPM and refered the same link

http://wiki.sdn.sap.com/wiki/display/XI/File-RFC-File%28Without+BPM%29

I have given the following in Sender File CC

Processing sequence :

AF_Modules/RequestResponseBean

CallSapAdapter

AF_Modules/ResponseOnewayBean

Module Configuration

passThrough

receiverChannel

receiverService

[Former Member]

Hi Suraj,

Can you help me solve this error.

[former_member187339]

Hi,

There seems to be some problem with the configuration of these two modules in your Communication channel. I will suggest you to try and play with the different parameters for these modules as give in help.sap

http://help.sap.com/saphelp_nwpi71/helpdata/EN/45/20c210c20a0732e10000000a155369/content.htm

http://help.sap.com/saphelp_nwpi71/helpdata/EN/45/20cc5dc2180733e10000000a155369/content.htm

PS: The wiki link may be showing some module and by specifying only those you may or may not get the result. So I will suggest you to check the above link and try to put some more parameters for the module's.

Can you paste the full error over here?

Then it would be easier to get the solution for you.

[Former Member]

adapter engine (your file adapter) error will not reflect in moni, go to communication channel monitoring and check audit log of file communication channel.

[Former Member]

it just shows

File processing failed with java.lang.NullPointerException

[Former Member]

> File processing failed with java.lang.NullPointerException

One reason could be FCC at receiver side. How you have defined your FCC?

[Former Member]

my output file record structure :

DT_out

itab_out 0.........1

item 0...... unbounded

STR 0........1

So i have given in the receiver FCC parameters as:

Record structure : item,ITAB_OUT

Content conversion parameters:

item.fieldFixedLengths 255

item.endSeparator 'nl'

ITAB_OUT.fieldFixedLengths 255

ITAB_OUT.endSeparator 'nl'

[Former Member]

First of all it is case sensitive, so make sure to use same case as you used in your output record structure.

Secondly the order in your Record structure : item,ITAB_OUT is wrong. It shoud be itab_out,item.

Lastly, just remove " ITAB_OUT.fieldFixedLengths 255" from your FCC why because this is your parent node which don't require to have any fixed length.

So after doing above modification try again.

[Former Member]

i have given the record structure as mentioned by you:

ITAB_OUT,item

But if i am removing 'ITAB_OUT.fieldSeparator' or 'ITAB_OUT.fieldFixedLengths' it was showing the following error in Receiver File CC

*Conversion initialization failed: java.lang.Exception: java.lang.Exception: Error(s) in XML conversion parameters found: Parameter 'ITAB_OUT.fieldFixedLengths' or 'ITAB_OUT.fieldSeparator' is missing *

so i have added ITAB_OUT.fieldSeparator 'nl'

but still showing the same error Error: java.lang.NullPointerException

[Former Member]

Any solutions / suggestions for my error?

[Former Member]

Hi,

Just try this combination..

Record structure : ITAB_OUT,item

Content conversion parameters:
item.addHeaderLine     0
item.fieldFixedLengths 255
item.endSeparator 'nl'
ITAB_OUT.fieldSeparator 'nl'

[Former Member]

it didnt help... getting the following error:

Error: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Channel has not been correctly initialized and cannot process messages

[Former Member]

Hi Sarvesh,

Can you help me to sort out this error

[Former Member]

Raised an OSS message for this, and SAP provided a patch. so the error message turned to a warning message.

[Former Member]

Can you please share what SAP's solution? Was it a note or something else?

thx in adv

praveen

[Former Member]

Hi,

Try to apply the Note 1261159 and the SAP_BASIS support level is atleast SAPKB71009.

Also check whether the receiver communication channel's module configuration is following the sequence:

1 AF_Modules/DynamicConfigurationBean Local Enterprise Bean 0

2 CallSapAdapter Local Enterprise Bean 1

If you wish, send me your mail address so that i send you the file received from SAP.

You can also look into the OSS message 54091 and look for com.sap.aii.adapter.file.svc.zip in the attachments. Ask your basis team to deploy this.
