Read messageID without Java Mapping

Hello,
is there a simple way to read the messageID and assign it to a target element without using a Java Mapping?
Background is that I want to use a messageID as correlationID in a BPM send step. Maybe by using a UDF.
Thank you for your help.

Hi Florian,
You can get this by using a simple udf. MessageId is the attribute in which you can get your message id. Please see this help for the udf:
http://help.sap.com/saphelp_nw04/helpdata/en/43/03612cdecc6e76e10000000a422035/content.htm
Here he is getting file name which is in FileName attribute. You can use MessageId where you have filename which will get you the message id.
Also whle testing in test tab of mapping there is paramers tab there put some id in message id. Then your test wil run else it will throw error or you may need to run end to end to work.

Read Attachments using Java Mapping API

Hello,
after investigating the Java Mapping API a little deeper I found some very interesting Interfaces "InputAttachments" and "Attachments" which could do exactly what is required:
Reading attachments and convert them into base64 code.
As I am not an experienced Java Programmer howeve, I am note sure how to use those interfaces.
For example there is a method defined in interface "InputAttachments":
Attachment getAttachment(String contentID)
How do I use it? If I use it in a way like "InputAttachments.getAttachment("abc");" then I get the error that it is not a static method. However how do I instantiate "InputAttachments".? As it is an interface I am not sure how to do this.
Any idea how to handle these methods?

Hi,
I am working on the similar. I am able to attach txt files and csv files but have trouble attaching xcel and pdf's. Any input is appreciated. Thanks

Java mapping - for reading the binary file contents and changing filename

Hi,
I have already gone through the various bolgs and threads and have not been able to find a solution to my problem.
One blog did give some idea but did not help- "JAAPPING", an alternate way of reading a CSV file
I am not very good in java but have been trying some out recently to fulfill the interface requirements.
I would really appreciate if you could help am I am giving below the detailed scenario below.
Part 1- working fine - The incoming file looks like:
:20:STMEMU096868DUBE
:25:001180256210
:28C:00371/00001
:60F:C090617AED742136,92
:61:0906300630CD34,27FINTCREDIT INTEREST
26MAY2009 TO 25JUN2009
:62F:C090630AED742171,19
:64:C090630AED742171,19
The file name as received is:TCDE.BLQSAM.SAEA2682.C0084025.A9G24T58.20090724195908
This file without any conversion is placed on XI server dircetory folder.
Part 2 - need to develop
The file should now be renamed according to the incoming value in 2nd line - specifically the 12 digit value 001180256210 and placed on the R/3 dircetory folder.
The new file name in the above example should be:
AC_NO_001180256210_datetime
The module for the above was created and the last time I checked it was working.
However, when I wanted to do final testing in Dev and move the changes further, the module has seemed to have stopped working so I need an alternate solution fast.
I was thinking of doing the Java mapping as I will be more in control as to what is going on thereby reducing the dependency.
There is no need to create any target xml structure as the file as it is needs to be placed in the target folder with a new name.
I can get the file name in UDF which I have already created but i am not usre if it working.
Can you please help?
Any help will be greatly appreciated.

Hi Stephen
The xml must be getting added in the below part of the code. It is coming from arg[0]
You can put a check and get it removed.
while ((len = arg0.read(buffer)) != -1) {
arg1.write(buffer, 0, len);

Read Filename form Adapter-Specific Message Attributes in Java Mapping

Hi,
I have scenario File to Mail adapter. How can i read filename from Adapter-Specific Message Attributes
in java mapping.
Thank you and Best regards
Fernand

Hello Fernand,
Are u using DOM or SAX parser?
In any case just put the Dynamic config code in the execute function or the other option is to define it as a private functionand call it in the execute,My personal advice would be the former.
Just put this code in ur java mapping
As fellow sdn ers have mentioned there is no need of the container method,just initialise the set param method and use it in the dynamice config code as follows
public class YourClass implements StreamTransformation
     private Map map;
public void setParameter(Map param)
     map = param;
public void execute(InputStream in, OutputStream out) throws StreamTransformationException
               DynamicConfiguration conf =(DynamicConfiguration) map.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
               DynamicConfigurationKey KEY_FILENAME =DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
// read value
File = conf.get(KEY_FILENAME);
Now just call File in the mapping program,
Should help u out

Without BPM:Call RFC using JCO in interface mapping using java mapping

Hi all
I have a very small scenario where REQUEST from the customer comes via Web Service all i have to do is to read the request using SOAP adapter and call an interface mapping(lets say the name is IM_TEST) inside which there is a JAVA MAPPING program written which will call an RFC in CRM using JCO.
Now this was really simple and i cud test the Interface mapping successfully, but the problem is when loading the scenario in integration directory i have certain things to do
1. to set the SENDER AGREEMENT which i did correctly
2. set the RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT now here i am stuck because there is no receiver in my case as the RFC is called inside the mapping only.
can i call one more message mapping in IM_TEST which will write file onto the XI directory and then in RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT i can mention the reciever as FTP.
I tried it but i gives the following error
Runtime exception occurred during execution of application mapping program com/sap/xi/tf/_MM_TEST_WRITE_FILE: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Parsing an empty source. Root element expected!
Please help me how to complete the scenario so that customer can run it end to end.

What do i do then...actually this is the project requirement. They want a very fast response from PI and thats why they wnt us to omit BPM and the Graphical mapping from the scenario.
I am able to test the interface mapping which calls the the Java mapping inside which there is an RFC call, but i cannot implement it end - to - end as there is no receiver business system in this case. The only business system i have is the SOAP sender.
I am really troubled now, please help me with a solution.
Is there any other possible way through which the process can become very fast whic hcan meet their requirement.

Read DataType Definition in a Java Mapping,

Hi,
Is there a way to load a DataType Definition and parse the fields and attribute of this data type from java code?
I am in a custom Adapter Module (PI 7.1) and need to dynamically load the definition of a DataType to do some FCC.
I would like to do the FCC based on the DataType definition rather then on the Communication Channel's adapter module configuration.
Thanks,
Martin

Hi Martin Lavoie,
I understand, you are getting a flat file and want to convert it into XML or the other way, converting XML to flat file in SAP PI 7.1 using File channel.
First, why you are going for Adapter module? (I think even you don't like it) It is resource intensive to develop, running in production system, maintain. If already there is an adapter module, leave it as it is. Consider using Java mapping over adapter module. Java mapping is relatively less resource intensive to develop, running in production system, maintain. Java mapping can do the payload conversion what you are planning to do in adapter module. If you write adapter module (generic), you have to use it in interfaces (all channels) where you need to transform the payload. If you write java mapping (generic), you can use it in operational mapping in all interfaces where you need payload transformation, along with other graphical mappings.
Second, as of now, there is no way to access Data type XSD (which are declared in ESR) using SAP PI. In PI 7.1 EHp1 payload validation using XSD can be done, by placing XSD file in folder on PI server. From PI 7.3, validation is based on Data type (XSD) defined in ESR. First place, you are interested in payload transformation not payload validation. So there is no way you can access XSD in ESR from Adapter module dynamically. I guess you can upload XSD along with adapter module, but maintenance in not all easy.
Finally, I donu2019t recommend adapter module for you requirement. Try using FCC. You may say whenever there is change in XSD (change in field lengths), you have to change FCC (edit the channel), and I donu2019t see better option than this. If you think FCC will not be sufficient for your requirement, and then go for Java mapping. Writing generic java mapping will be a good challenge. Java mapping should be uploaded with XSD (or parameter file) for every interface and should be edited if there is a change in XSD.

Accessing SAP:HopList element in message header from JAVA-mapping

Dear Experts,
Is it possible to access the SAP:HopList element from message header in JAVA-mapping?
I need this to get the list off all receivers of current message (I have a ReceiverDetermination with two receivers, without any conditions, so both receivers are receiving each message and in InterfaceDetermination to one of the receivers I have a JAVA-mapping, in which I need to know the name of another receiver. And the SAP:HopList is containing this information).
Or maybe where is some other solution?
Best Regards,
Artsiom Anichenka

That's tricky, since the proper way of doing it would be through BPM.
Anyway, if you expose your XI interface as a WebService (Soap sender cc) you could access it through Mapping Lookup (lookup works for RFC, DB and Soap lookups). Check https://help.sap.com/javadocs/NW04S/current/pi/index.html
But be aware that Mapping Lookup API is not intended for inserts/updates (since it doesn't contain any transacational handling), just mere lookups (selects in tables), so I'm not sure it is the best approach for your case.

Henrique.

Java mapping for XSD Validation

Hello,
I have developed a Java mapping to validate an XML based on XSD.
I works fine and generates a message with error details.
I would like to create a report with all errors encountered during this Validation and to stop this message from being sent to the partner.
But this Java mapping stops at first error encountered and generates an error message with first error only even though document has more errors further.
Can anyone please let me know if there is an option to log all errors without allowing the message to go through?
Thanks.
Best Regards,
Shweta

Yes, as abhishek mentioned when you validate the instance document (XML) using standard parsers then they validate based on the spec provided in XSD and they stop at the first error. The link given using dom parser via java code will also stop at the first error.
If you really want to validate the entire instance document then you might have to create a custom validator class which does validation for each and every fields and store it in an object like Vector or List or Map object. Then when you throw exception you can retrieve that Map object in the catch block and read all the individual error messages and display in log. This requires additional effort. In this case you dont rely on parser validation. Completely custom based.
Example:
Vector errorList = new Vector();
if the field name is SSN and if you see any alpha characters you add error for that field in the errorList
If(SSN.matches("[a-zA-Z]")){
do nothing
}else{
errorList.add("The fieldName SSN contains other than alpha characters");
Like that you have to add error string mesg in the errorList object and return the errorList at the end.

Java mapping runtime issue

Hi,
I have currently created a java mapping which unzips files and transforms plain text/falt files to xml according to a specific structure... So far so good. This stuff works perfectly when testing interface mapping in the repository. However at runtime it does not work, and this is where you clever guys come into the picture:-)
It should be mentioned that the zip-file is dropped on a MQ-queue and picked up in XI and passed on to a BPM - the only thing the BPM does is to perform the java mapping and afterwards send one of the messages to R/3 and the other to CRM.
The concrete error given at runtime in the PE is:
Error handling for work item 000000718016
Work item 000000718016: Object CL_SWF_XI_MSG_BROKER method CALL_TRANSFORMATION cannot be executed
Parsing error before mapping: unexpected end-of-file (line 1, column 1)
Hope somone can help me on this matter,

Hi Alex,
Thanks for your reply. First of all I was wondering if I missed something somewhere in my generel understanding of XI and BPM's!? - I kind of sense some irony/sarkasm in beginning of your reply:-) As far as I know BPM should have no trouble receing non-xml (in my case zip-files)!?
Anyways here goes:
1. Yes, this is also my impression that is should be possible somehow (we do currently run sp14). However, I havent yet figured out how to do it in this case. When trying to create interface mapping between the three involved software components, I get a 'MESS_MULTI_MAP_IF_WRONG_SWCV' three times. I've searched around without being able to find any information on the error. I does seem, though, like the problem is that all objects aren't in the same software component!! But this approach is of course the prefered one...
2. Well - you got me there. Kind of expected someone to point that out:-) This is of course something to be looked into also in order to "improve"/"enhance" the program - though it, as already pointed out, works perfectly as is.
3. This part I have also thought about - though quickly moved away from the idea, but that is only due to lacking insight/knowhow on the subject. Interesting weblog you have written, something so I will investigate further when time allows for it:-)
Best regards,
Daniel

Java mapping - Setting the name of the file dinamically

Hi all,
Problem: I know how to set the name of the file in an Idoc to file interface if I'm using a message mapping, but not if I'm using a Java mapping.
I'm using this code inside a user-defined function of the message mapping so that I can set the name of the file dinamically:
public String GetFileName(String inboundParameter,String IdocNumber,Container container){
String filename;
java.text.SimpleDateFormat dateformat = new java.text.SimpleDateFormat( "yyyyMMdd" );
filename = "cikk_" + dateformat.format( new java.util.Date() ) "_" IdocNumber + ".txt";
DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create( "http://sap.com/xi/XI/System/File", "FileName");
conf.put(key, filename);
return inboundParameter;
(See also: /people/michal.krawczyk2/blog/2005/11/10/xi-the-same-filename-from-a-sender-to-a-receiver-file-adapter--sp14)
But how can I do that if I'm using a Java mapping??
I don't have the class Container there. How can I retrieve the DynamicConfiguration object without that class?
Thank you very much.

Thank you Jin,
I knew that it had to be related with the Map object got in setParameter, but in this link:
http://help.sap.com/saphelp_nw04/helpdata/en/0f/80243b4a66ae0ce10000000a11402f/frameset.htm
you can't find the constant DYNAMIC_CONFIGURATION.
I think it's not up to date.

JAVA Mapping: Convert the InputStream in to OutputStream out

Hi everybody,
I'd like to code my first JAVA Mapping. For this I would just like to convert the InputStream in to OutputStream out.
This does not work:
out = new FileOutputStream(new File(in));
How has the code look like?
Thanks, regards
Mario

Hi Mario.
Do you want to convert input into output directly without doing any transformation?
The way I've always used is to load the input document first:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(inputStream);
After loading the document you can parse it's content with DOM API.
Finally you create the transformed document and return it through outputstream:
Document resultDoc = builder.newDocument();
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource source = new DOMSource(resultDoc);
StreamResult result = new StreamResult(outputStream);
transformer.transform(source, result);
If you want to convert the input to output you can use:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse(inputStream);
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(outputStream);
transformer.transform(source, result);
At this point, I think you will have the input into the output.

Get dynamic filename in a Java Mapping (NOT UDF)

Hi,
we are using a Java Mapping step in XI (not UDF). We need to have access to the filename. In the File Adapter we set the message attributes and can see the filename value in the SXMB_MONI.
We use the following code fragment to have access to the filename:
Container container = new Context(new FunctionWrapper(0));
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String sourceFileName = conf.get(key);
This doesn't work. We think the declaration of the container class is wrong. Does anybody have some information about using the dynamic attributes in Java Mappings?
Thanks in advance
Michael

PI Java Mapping NullPointerException

Hi Gurus,
I'm having some troubles doing the mapping through java mapping in PI.
I've done the java class in the SAP NWDS and imported it on PI through the ESR.
Now i'm trying to test through the SOAP and i've found the following error in the "Communication Channel Monitor":
500 Internal Server Error SAP NetWeaver Application Server/Java AS
java.lang.NullPointerException: while trying to invoke the method com.sap.aii.af.sdk.xi.lang.Binary.getBytes() of a null object returned from com.sap.aii.af.sdk.xi.mo.xmb.XMBPayload.getContent()
And the following error in the SXMB_MONI:
<SAP:Category>XIServer</SAP:Category>

Am i doing anything wrong in the code? Where can this nullpointerexception be triggered?
Thanks.

These three xml are the same:
<?xml version="1.0"?><a:xml xmlns:a="urn:123">root</a:xml>
<?xml version="1.0"?><xml xmlns="urn:123">root</xml>
<?xml version="1.0"?><ns0:xml xmlns:ns0="urn:123">root</ns0:xml>
But your code will work only with last one, because it doesn't bound namespace to prefix ns0.
