Hi
Then write a logic for the node
if Source node (ifexits) then map the source node to Target node
else
Map constant (Space) to the target node , if no source node the it will create just target node.

How to handle empty file using sftp adapter
Hi,
Please explain me how to handle empty files in sftp adapter.
Thanks,
EnivassHi Enivaas,
I don't have the seeburger sftp adapter at hand at the moment, but asfar as I remember, this does not specifically have an empty-file handling option like the standard ftp adapter.
So to stop emtyp files from being written, guess would need to handle this at the mapping level. For example, check for target creation criteria in the header node in mapping. If the creation criteria is not met, you can throw an error in mapping.
You may also incorporate this condition in your Receiver determination. In this case, if the condition is not satisfied, no receiver is determined in PI.

Hi Experts,
I am doing File to File Scenario.
If my Sender systems file is Empty , that means there is no Records in the File .
How to Handle Empty Files ??????????
I want to know For both Sender and As wel as Receiver Adapters
Please Let me know..
Regards
KhannaSee if u are having a sender file adapter and the file is empty u can tell the if it has to 'Process the empty file' or 'Skip the empty file processing'.
Similarly if you have a message to going to your Receiver file adapter and the message is empty then you can decide still if you want to create a 'File with empty records' or skip creating the same.

Hello all,
In my scenario i am using file as my sender, if the file size is zero then how to throw an exception saying that the file is empty to the user. how will i handle this issue.
thanks in advance,
Pradeep NHI,
What do you want . you mean raise an exception,
See we can raise an Runtime exception from message mapping by using UDF
In UDF
if the source message is empty then throw new RuntimeExceptio("Own message");
Check and try , this can be handled in determination by terminate the processing.

Can some one point me how to process this empty file.
Thanks,
NandiniHandling of Empty Files
Specify how empty files (length 0 bytes) are to be handled.
○ Do Not Create Message
No XI messages are created from empty files.
The files are processed according to the selected processing mode.
For example, if the processing mode is Delete, empty files are deleted in the source directory.
○ Process Empty Files
XI messages are created with an empty main payload.
The files are processed according to the selected processing mode.
○ Skip Empty Files
No XI messages are created from empty files.
Empty files are skipped and remain in the source directory.
These three options are available for handling empty files in XI SP 19 and PI SP 10 and above.
Select the option :Do Not Create Message" -

Receiver file adapter creates empty files, Empty-Message Handling SP19
Hello,
We have just upgraded the system to SP19.
One of the new features is that it should be possible to determine how XI messages with an empty main payload are to be handled in the receiver file adapter.
If the parameter Empty-Message Handling is set to 'Ignore' no file should be created if the main payload is empty. In our case an empty file (size 0 kb) is still created even though the main payload is empty and the flag is set to 'Ignore'.
Has anybody experienced the same problem?
// Best regards HansThis should work:
Use your own adapter module that parses incoming message and checks if it has any record sets in the document. If it does not have any record sets, then set the message to empty and then give this modified message to File receiver.
For example, see the example code below:
Module imports..
Audit log import..
DOM imports/SAX imports..
public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
try {
// get the XI message from the environment
Message msg = (Message) inputModuleData.getPrincipalData();
AuditMessageKey amk = new AuditMessageKey(msg.getMessageId(),AuditDirection.INBOUND);
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS,"RemoveRootTag: Module called");
XMLPayload payLoad = msg.getDocument();
Document doc = parseXmlFile(payLoad.getInputStream());
if(doc != null){
if(!doc.getDocumentElement().hasChildNodes()){
Audit.addAuditLogEntry(amk, AuditLogStatus.SUCCESS, "Document is empty!!");
payLoad.setContent("".getBytes());
msg.setDocument(payLoad);
// provide the XI message for returning
inputModuleData.setPrincipalData(msg);
} catch (Exception e) {
// raise exception, when an error occurred
ModuleException me = new ModuleException(e);
throw me;
// return XI message
return inputModuleData;
private Document parseXmlFile(InputStream xmlpayload) {
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(false);
// Create the builder and parse the file
Document doc = factory.newDocumentBuilder().parse(xmlpayload);
return doc;
} catch (SAXException e) {
} catch (ParserConfigurationException e) {
} catch(IOException e){
return null; -
Problem with „Empty-File Handling" in PI 7.11
Hi,
Iu2019m working in PI 7.11 with file adapter, Sender CC, option: Empty-File Handling: Process Empty Files.
What I want to do is giving target file the system-date, if the source file is empty.
But I always get a mapping error in RTWB: Premature end of file.
It seems that the payload is empty.
Any idea?
Thanks a lot in advance!
Rene Dong
Edited by: Rene Dong on Aug 31, 2010 4:20 PMWhat I want to do is giving target file the system-date, if the source file is empty.
The error you are getting makes sense. You should do a check in the mapping, if the payload is empty then use brute force to pass the system date. -
Hi All,
I have a scenario, in which there is a possiblity of getting source file to be empty (0 bytes), In this case I need to trigger an email to the user reg the same. Please provide inputs.
Regards,
NithiyanandamHi,
Maybe you can try out these scenario..
In the sender file channel, keep option as process Empty files and in the sender ASMA properties, select options file name and source file size.
Then in your message map, from a UDF, if the file size in ASMA is zero, you can trigger an email to the intended recipient. Search in SDN, you will get the code for triggering email from a UDF.
Another option would be to go for a conditional receiver determination. There the condition would be the file size of the source file.
In the receiver determination, select condition --> Context Object --> SourceFileSize under file namespace.. If this is 0, select a mail recipient as the receiver and send mail using mail adapter.
If file size is not 0, select your original receiver.

Empty File Handling in xLink adapter
Helloo Experts
I am doing a scenario, which creates an empty file(when some mapping condition doesnt satisfy).
I dont want to write this empty file in the target directory.
This can be handled if a file adapter is used, but I am using a SOAP AXIS adapter, so I dont know how to handle this here.
I alaso tried using the StrictXml2PlainBean to avoid the creation, it creates 0 documents and a 0kb empty file.
Can anyone please let me know how this can be solved????
Also if some one has done this empty file handling in J2SE file adapter...can you tell how it was done.
Thanks a lot!!!!!!
Regards
ShobhaHi Gabriel,
You can write a simple script to copy a file from source folder to target in case the fiel size is ZERO bytes. The script will not copy the file if the filesize is more than zero bytes, This will be processed normally by PI server. You can call the script from sender communication channel parameter : "RUN OS command before message processing". Could you please specify the Operating System (OS) you are using in your PI server.
