Java mapping for Dynamic File name: stuctures?

Hi,
Scenario: Sender AS2 adapter --> PI --> Receiver File (NFS) Adapter. Just a file pass through, no mapping
Requirement: Want to have the receiver file name as C1.yymmdd.C2 where C1 and C2 are contants and yymmdd is current date.
I was told in sdn forum that I have to write java mapping and provided the sample code also. However, I am not sure how and where to use that sample code. Could you please help on following questions:
1) What is the source and target data type structures for mapping?
2) Where do I develop java mapping? How do I import to PI?
3) How do I get access to SAP Netweaver Developer Studio? Can I download it to my laptop? or if I dont have access, can I use any other tool to develop? ( NetBeans, Eclipse ??) and how?
4) what are the files and libraries that we need to import to java mapping? (e.g., Import aii_map_api.jar library)
5) How to generate .jar file?
If someone has already developed java mapping (.jar file) ready to import into PI, please provide the same.
Thanks in advance

Hi Sarvesh,
Is this UDF work if I dont select ASMP on sender side? (We tested selecting ASMP on both sender & receiver file adapters, it works fine and it works without UDF also).
In my requirement I have to use sender AS2 adpter, please confirm if I can use this UDF without selecting ASMP on sender side.
I have done the following tests:
Test-1) Select ASMP with 'File Name' on both sender and receiver file adapters without any mapping (UDF)
It works great. No UDF or mapping required. It is just pass through of file having the receiver file name same as in sender channel.
Test-2) Select ASMP with 'File Name', only on receiver file adapter without any mapping (UDF)
It is obvious, it doesn't work. I am getting the following error:
Could not process due to error: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: The Adapter Message Property 'FileName' was configured as mandatory element, but there is no 'DynamicConfiguration' element in the XI Message header
Test-3) Select ASMP with 'File Name', only on receiver file adapter with mapping (using DynamicConfiguratio UDF)
We are getting the following error message in SXMB_MONI:
Fatal Error: com.sap.engine.lib.xml.parser.Parser~
<SAP:Stack>com.sap.aii.utilxi.misc.api.BaseRuntimeException thrown during application mapping com/sap/xi/tf/_MM_Filename_: Fatal Error: com.sap.engine.lib.xml.parser.Parser~</SAP:Stack>
Here is the code we have in UDF:
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String SourceFileName = "C1." + a + ".C2";
conf.put(key, SourceFileName);
return " ";
So looks like UDF is not working and it is failing in mapping. If I could make it work, I think there is good chance that I can see DynamicConfiguration under SOAP Header, which what required for the error we see in out test-2.
Can someone please help me to straighten this UDF and make it work.
Thanks in advance.

Java Mapping for Flat file

hello SDNers,
I am using JAVA mapping for converting FlatFlie IDoc to IDoc and i am using metadata for this.While downloading metadata from SAP system, the first segment in the data record is having level 2.
1) What is the use of Level in metadata?
2) What is the Level for first segment in data record of metadata. Is it Level 1 or Level 2?
3) I am facing an error while appending the node. Is it because of Level differs?
Plese help me out and thanks in advance

Hi,

this shows how the nested segments in IDOC are to be understood
>>>3) I am facing an error while appending the node. Is it because of Level differs?
no, it becase your code is incorrect - the level velidation will be done at the receiver

Variable substitution not working for dynamic file name in Receiver File CC

Hi Experts,
I am doing the scenario of Proxy sender to File receiver and my purpose is to Create the text file
as per the filename available in Source Message payload.
I am using the Variable Substitution method for this as shown below.
Source Message Structure:-
     <Row>            -
having Cocurence 1.1
         <Filename>     -
having Cocurence 1.1
         <Item>            -
having Cocurence 1.Unbounded
          <Field1>
          <field2>
         <Item>
         <Item>
          <Field1>
          <field2>
            <Item>
     <Row>
Target structure is same as the source structure and i have mapped the Filename field of the Source
with the Target structure Filename.
In ID the following is the File receiver CC Configuration.
File Name Scheme:- %Dyn_filename%
In Advance tab, I have selected the Enable option and added one row as Variable name %Dyn_filename%
and Reference as payload:Row,1,Filename,1
In testing I am getting the Error as 'variable Dyn_filename is not found in Message payload'.
Please suggest me.

File Adapter: Dynamic file name

Hello,
I would like to use a filename like this:
Name.<DOCNUM>.Direction.<Timestamp>
For DOCNUM I use variable substitution. Works fine.
For <Timestamp> I need a different format as the timestamp function
in file adapter create. So I try to set up my timestamp in mapping like
dynamic file name:
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "Timestamp");
conf.put(key1, a);
Input a is date function which creates my desired timestamp format. In file adapter I try this:
Name.%DOCNUM%.Direction.%Timestamp%
or
Name.%DOCNUM%.Direction.Timestamp
or
Timestamp
all doesn't work for Timestamp.
So is there a possibility to configure a dynamic filename like this???
Is there a possibility to access dynamic configuration variables in dynamic filename except
the known for filename and directory??
thanks
chris

your file name needs to be
Name.<DOCNUM>.Direction.<Timestamp>
dont use variable substitution. use only dynamic configuration and set the file name
introduce a logic that will create the string
Name.<DOCNUM>.Direction.<Timestamp>
eg. String filename = "Name" + var_docnum + "Direction" + var_timestamp;
then use the dynamic conf code to set the file name and use adapter specific properties in you adapter to retrieve it.

Variable subsitution for target file names

Hi All,
I am using variable subsitution for dynamic file names. I am using the multimapping for multiple files in the target.So i coluld not able to use the dynamic configuration for file names. Now i want to replace all the spaces in the filename to underscore.
For example
My payload filed value "file name in the target file".
Now my filename "file_name_in_the_target_file".
How to achieve this using Variable subsitution.
Regards,
Ramalakshmi.G

Use replaceString Function.
file name
Constant (" ") --> replaceString -------> TargetField
Constant ("_")

Dynamic file name ?

Hi,
I am following this blog to name the target file/directory dynamically at the runtime :
/people/sameer.shadab/blog/2005/09/23/an-interesting-usage-of-variable-substitution-in-xi
But I am getting this error in the CC monitoring :
Could not process due to error: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: Unknown message header category 'interface_name ' for variable 'var1'.

Hi,
Try following this weblog for dynamic file name.
/people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14
Dynamic filename come under the Dynamic configuration in moni, for your messages.
This is the code used inside.
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
That is why Dynamic configuration is coming in output.. It is a class to generate dynamic configuration file at runtime provided by SAP XI.
Hope this will help you.

How to give a dynamic File Name for Receiver File/FTP Adapter.

Hi Experts,
    I have one scenario in which we are creating a flat file of IDOC which is coming from R/3 & sending it to FTP location. For this we have configured Receiver FTP adapter with File Name Scheme as "NT.out" & in File Consturction mode i have given as "Add Time Stamp".
    therfore while creating a file it is creating as NTyyyyMMdd-HHmmss-SSS.out
where as my requirement is only to to add Time & not the Date. (NThhmmss.out)
    How to do this ?
    for your info we are using ABAP Mapping.
    Pl help me
Regards,
Umesh

Hi Umesh,
      Add one more field to your target structure for your file name and populate that field as per your requirement like NTyyyyMMdd.out. In receiver communication channel use Variable subtiution option and give the refrence of Payload and file construction mode set as create.
And refer the below weblogs for Variable Subtiutuion File Name Scheme

Dynamic File Name on Receiver Side using XSLT mapping

Hi,
My scenario is a Proxy to File scenario.The File on the receiving side is a TEXT file generated due to XSLT mapping. The file name has to be dynamic like- TEST<DDMMYYHHMMSS>File.DAT.
If somebody knows how to do the same please help.
Regards
Ritu

Hi Ritu,
I agree to Krishna.With your XSLT mapping create a XML output which can be converted to a text file with content conversion.
And for the dynamic file name, i guess its the date that matters which needs to be in DDMMYYHHMMSS format. the same can be accomplished by a Java function and calling it in your XSLT .
Do refer this weblog it will help you accomplish the same.

Dynamic file name within 1:n mapping

Dear all,
I have a 1:n mapping and would like to use dynamic file names.
I searched the forum but found just some few anserws.
As far as I can determine, it is not possible to use dynamic file names for multiple target messages, right?
We are using a 3rd party adapter (SFTP) that doesn't support variable substitution.
Is there another way?
Thanks
Chris

>>As far as I can determine, it is not possible to use dynamic file names for multiple target messages, right?
I am afraid you are correct.
>>Is there another way?
One option I could think is have an adpter module and adding the dynamic configuration there.
I personally have not tried this option. But I dont see any reason, why this approach would fail.
If I am correct, the message is passed to the module chain after the split. So the above logic should work.
I will be glad if you can try and let me know the results
Regards
Jai
P.S: Let me know if you need any help creating the module. The coding should be so simple and not more than 10 lines

FTP adapter for Oracle Service Bus - retrieve file by dynamic file name.

Hi
I am newbie in OSB. I try to use FTP transport in Workshop, it must fill in "Prefix" and "Suffix" for destination file name.
But for us, the file name is sent by external systems.
The workflow is:
1. External system call our proxy services.
2. Proxy service get file name from SOAP message.
3. Proxy Service get the file from FTP server.
4. The file send to Business services.
Any suggestions to implement about workflows?

Let me first put here what I understand about the flow:
External Sytem -->(filename)--> OSB HTTP PS --> (1) --> OSB FTP BS --> Read file based on filename
|--> (2) --> send file ontent to another system or return to the original system
If that is the flow, then I beileve ther is no straight forward way to implement it in OSB.
OSB FTP BS will only write a file to FTP Location.
If you create a JCA FTP Adapter for reading the file, then you can use it only to create a Proxy Service, and that proxy will not pick up the file when called from another service but only when a file is put on the source FTP location.
So, to implement the solution you will need to use Java Callout to a class which has code written to accept the file name as input, read the file from an FTP location and return the file content.
This is my understanding of how it is, may be there is another way to implement this or in fact may be the latest version of OSB 11.1.1.4 or 11.1.1.5 JCA adapter does support read operation within a flow instead of just at the start of the flow.

Dynamic File Name - UDF

Hi Master,
I written the UDF for Getting the Dynamic File name.
DynamicConfiguration conf = (DynamicConfiguration) container.getParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
// Retrieve the filename
String FileName = conf.get(key);
This is working ok - but I want to return these values so I can be used in mapping.
when I try to add the statement return FileName; , the compiler then complains with the following error:
cannot return a value from method whose result type is void return FileName;
Please help me,
Thanks,

Dynamic file name in communication channel

hello
is it possible to give in the communication channel, under the 'File Access Parameters', a dynamic file name?
to get it out of a table or something?
Thanks
Kfir

Hi,
Yes its bit possible to use the dynamic file name at File access paramters
The dynamic filename generation concept is as follows.
In your filename field. just give a variable with % symbols. (eg: %file% ).
Now, under the option Variable Name Substitution, you can give how the value has to be created.
It can be your interface name, sender service name, etc or it can be some value dynamically from your payload.
For the former, your give
message:interface_name ,etc
and for the payload part you give,
Payload: "your element root which u wanna acecss"
Just check this link out,
http://help.sap.com/saphelp_nw04/helpdata/en/bc/bb79d6061007419a081e58cbeaaf28/content.htm
And read the contents under variable substitution and it will help you understand the concepts better.

Hi Ralf,
i think, you need for each XML msg (each different root element) a new adapter -> a new IF determination, new rec agreement and a new channel.
