JAVA mapping, output...
Hello guys,
Again here I am with some simple and easy doubts.
When I'm creating a mapping between two interfaces with JAVA, I'll have a call to :
execute(InputStream in, OutputStream out).
The questions are, these two arguments are two XML files. The first will be the file we want to send, but the second how will it be?
If I'm using a call to a RFC, the structure of the second file will have the importing, exporting and tables arguments of the RFC? And how are they disposed...?
The idea is to perform the correspondence from the original file to the parameters of the RFC, but how will the RFC load the parameters from the file...?
I know it's a really simple doubt but can anyone clear my mind?
Thanks a lot in advance...

These arguments dont necessarily need to be XML structures, in fact this method accepts any kind of input i.e. flat structure, strings, etc.. However, you are using this mapping within a message mapping so most likely you will pass an XML structure to it. The first parameter is the input (the source) and the second one is the resultt of your Java mapping.

The RFC structure you have to download it from the R/3 system where you want to call this RFC. You do this from your SWCV in the repository. After you have downloaded the RFC metadata you will see both messages, the request and the response message.
> The idea is to perform the correspondence from the
> original file to the parameters of the RFC, but how
> will the RFC load the parameters from the file...?
Here is where your message mapping (enhanced with your Java mapping) will come into picture.
PS: Without knowiing your requirements I think you can do this mapping from file to RFC call without the use of a Java mapping. i.e. message mapping.

Output encoding in Java mapping ?
Hello,
I have written a Java mapping which reads an input document and creates an output document. My problem is, the German special characters are lost in the output document (wrong characters). This is strange, because I am only using regular DOM methods for adding the output nodes and values. Anybody has an idea where I have to explicitly define the output encoding ? XI automatically uses UTF-8, I am using the StandardDOMWriter class of the com.inqmy.lib.xml package from XI, and DocumentBuilder from javax.xml.parsers.
But the output is wrong nevertheless. I think the encoding is already set in the OutputStream input variable of the execute methods. So no need to be changed (?)
Code sample below:
public void execute(InputStream in, OutputStream out) throws StreamTransformationException {
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document idoc = documentBuilder.parse(in); // input document
Document odoc = documentBuilder.newDocument(); // output document
// create some elements and values with helper method below
// write output document to stream
odoc.appendChild(oRoot);
StandardDOMWriter sdw = new StandardDOMWriter();
sdw.write(odoc, out, null);
private Element createElement(String elementName, String value, Element parent, Document doc) {
Element element = createElement(elementName, parent, doc);
// here we put the input content to output value
element.appendChild(doc.createTextNode(value));
// ok, special character still there:
trace.addInfo("Read back: " + getNodeValue(element));
return element;
CSYI solved the problem. For some reason, the inqmy parser does not work correctly. If I remember correctly, the SapXMLToolkit (from where it comes), is deprecated anyway.
Instead I use now standard JAXP transform streaming, and that works fine:
// commented code does not convert german special characters correctly:
//StandardDOMWriter sdw = new StandardDOMWriter();
//sdw.write(odoc, out, null);
// Serialisation through Transform.
DOMSource domSource = new DOMSource(odoc);
StreamResult streamResult = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING,"UTF-8");
serializer.setOutputProperty(OutputKeys.INDENT,"yes");
serializer.transform(domSource, streamResult);

How can I get the output of graphical mapping as an input to java mapping?
Hi Experts,
I am using graphical mapping in my scenario to get an xml at the end, now after this i want to use java mapping and then do encryption on this input. I am using both the mappings in the same interface
Here the thing is, the input to the java mapping should be the output of the first graphical mapping.
How can I link the java mapping and graphical mapping so that Ill get the output of the graphical mapping as the input to the java mapping?
Some pointers to similar kind of implementations is highly appreciated.
Thanks in advance,
Thomas
Edited by: Thomas Varghese on Jan 22, 2009 11:35 AMhi,
the input to the jave mapping will be exaclty the same as if you don't have
any mapping before that
the only different is that the input will be XML of the output of the message mapping
have a look at my blog to see how to combine two mappings:

that's all

Creation of additional attachment in Java Mapping
Hello all,
I want to use a Java Mapping with the functionality to create a second /attachment which I can send over email out?
I dont want to pick this file somewhere from the server, instead I want to fill the content of the additional attachment directly in the java mapping.
I hope somebody knows the answer of my question.
If its possible is there any kind of example??
Many thanks for your help
ilkahi Stefan,
http://scn.sap.com/thread/1874962
Regarding the comment in this thread, can you please tell me if you have faced any issue with creating output attachments. Right now, i have a message mapping in which i have written a udf to create attachments
this message mapping is a multi mapping and the source is 0-unb. I have used a return as xml on the root message and pointed it to the udf after split by value.
There are three root nodes in one of my cases, and when this goes through this mapping, there is 1 attachemnt each created with three main documents and submain documents. However, all the attachments contain details of the first root node itself where in actually it should be each main and submain document having a different attachment. Please find my udf below. Please let me know if you think it is wrong somewhere.
udf :-
GlobalContainer globalContainer = container.getGlobalContainer();
OutputAttachments outputAttachments = globalContainer.getOutputAttachments() ;
int flag =0;
AbstractTrace trace = container.getTrace();
String attachmentName = "";
//for(int i=0;i<var1.length;i++){
try
var1=var1.replaceAll("><",">\n<");
attachmentName = "attachment"+cnt;
Attachment newopAttachment = outputAttachments.create((attachmentName), var1.getBytes("UTF-8"));
outputAttachments.setAttachment(newopAttachment);
trace.addInfo("newopAttachment"+newopAttachment);
cnt=cnt+1;
attachmentName ="";
newopAttachment = null;
var1="";
catch (Exception e)
trace.addInfo("ever reaching trace");
e.printStackTrace();
//result.addValue("1");
//result.addValue("1");
return "1";

Dynamic configuration not working in Java mapping
Hi All,
I have a scenario where i am using java mapping. In this i am doing following
1)Read file name from input message header
2)set file name in output message Header
3) set Directory name in output message Header
i have used following code .. but iit is not working... when i test end to end... in reciver communication channel it is failing stating " message failed as "Directory is not set in Header. Also i checked in SXMB_MONI "dynamic configuration".It is not showing Directory.
this is code.
public void transform(TransformationInput transformationInput,TransformationOutput transformationOutput)
throws StreamTransformationException {
private Map para;
String Directory ;
String inputFileName;
String var1 = "ABC";
para = transformationInput.getInputHeader().getAll();
DynamicConfiguration conf = (DynamicConfiguration) para
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keyFileName1 = DynamicConfigurationKey
.create("http://sap.com/xi/XI/System/File", "FileName");
inputFileName = conf.get(keyFileName1);
DynamicConfigurationKey keyFilename = DynamicConfigurationKey
.create("http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey keyDirecory = DynamicConfigurationKey
.create("http://sap.com/xi/XI/System/File", "Directory");
Directory = "tmp/"+var1;
conf.put(keyFilename,inputFileName);
conf.put(keyDirecory, Directory);
I am in PI 7.1 , and in eclipse its showing warning that Para is not used.
Can anyone show some lights.
Also is there any way to debug this?? like is there any function by which i can write the trace for each step to see those in MONI.Method name: public void createDirectory(Resultlist result, Container container)throws StreamTransformationException
//Use Simple UDF and do the following lines
String Directory ;
String inputFileName;
String var1 = "ABC";
DynamicConfiguration conf = container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keyFileName1 = DynamicConfigurationKey
.create("http://sap.com/xi/XI/System/File", "FileName");
inputFileName = conf.get(keyFileName1);
DynamicConfigurationKey keyFilename = DynamicConfigurationKey
.create("http://sap.com/xi/XI/System/File", "FileName");
DynamicConfigurationKey keyDirecory = DynamicConfigurationKey
.create("http://sap.com/xi/XI/System/File", "Directory");
Directory = "tmp/"+var1;
conf.put(keyFilename,inputFileName);
conf.put(keyDirecory, Directory);
and remove these 3 lines
//private Map para;
//para = transformationInput.getInputHeader().getAll();
//DynamicConfiguration conf = (DynamicConfiguration) para.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION
>>I am in PI 7.1 , and in eclipse its showing warning that Para is not used.Can anyone show some lights.
You can simply remove declaring Map Para line... The eclipse gives warning because you dont assign values for it and you are trying to use...
For using the same input file name in output side, you dont need coding ... you need only for the directory...
Enable ASMA attributes in the channel.

Java Mapping, XSLT Mapping, ABAP Mapping
Hi Experts,
Could any one explain what is the main features of the following Mapping. How to pick the mapping?
Java Mapping - When to use and what is the advantage.
ABAP Mapping - When to use and what is the advantage.
XSLT Mapping - When to use and what is the advantage.
Graphical Mapping - When to use and what is the advantage.
cheers,
SuneeThere are 4 types of mapping in XI
1. Graphical Mapping
2. XSLT Mapping
3. JAVA Mapping
4. ABAP Mapping
When to use Message mapping
1 When the logic for your mapping is simple and straight forward, you can use
Advantages of message mapping
1)Easy to use.
2) has GUI drag and drop.
3) used for simple mapping cases
4) it does not involve any complex logic
Disadvantages of message mapping
1)has limitation in terms of complex hierarchy
When to use Java mapping
1) Java mapping are used when graphical mapping cannot help you.
Advantages of Java Mapping
1)you can use Java APIs and Classes in it.
2) file look up or a DB lookup is possible
3) DOM is easier to use with lots of classes to help you create nodes and elements.
Disadvantages of Java mapping
1)SAX parser is not easy to develop
2)DOM parser is intensive
3) Java knowledge is required
4) bit complexer
XSLT Mapping - When to use
1)When the required output is other than XML like Text, Html or XHTML (html displayed as XML )
2)When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
3)When data is to be filtered based on certain fields (considering File as source)
4)When data is to be sorted based on certain field (considering File as source)
5)When data is to be grouped based on certain field (considering File as source)
Advantages of using XSLT mapping
1)XSLT program itself defines its own target structure.
2)XSLT programs can be imported into SAP XI. Message mapping step can be avoided. One can directly go for interface mapping once message interfaces are created and mapping is imported.
3)XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
4)File content conversion at receiver side can be avoided in case of text or html output.
5)Multiple occurrences of node within tree (source XML) can be handled easily.
6)XSLT can be used in combination with graphical mapping.
7)Multi-mapping is also possible using xslt.
8)XSLT can be used with ABAP and JAVA Extensions
Disadvantages of using XSLT mapping
1)Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
2)Interface mapping testing does not show proper error description. So errors in XSLT programs are difficult to trace in XI but can be easily identified outside XI using browser.
3)XSLT mapping requires more memory than mapping classes generated in Java.
4)XSLT program become lengthier as source structure fields grows in numbers.
5)XSLT program sometimes become complex to meet desired functionality.
6)Some XSL functions are dependent on version of browser.
Advantages of Abap Mapping
1) A person comfortable with OOABAP can go for ABAP mapping instead.
Disadvantages of Abap Mapping
1) Abap knowledge is required
2) bit compexer

Issue with java mapping in a multi-mapping scenario
Hi
We have a 1:n multiple mapping scenario in XI and the source is R3 proxy and target side is files. So, creating multiple file from a single message from R3 .
R3 --> XI --> Multiple files
Structure of the output of the multi-mapping is
- <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
- <ns0:Message1>
<Transaction>
</Transaction>
<Transaction>
</Transaction></ns0:Message1>
</ns0:Messages>
wherein each Transaction node represents a file.
Now, we need to introduce a constant /string like
<!DOCTYPE Transaction PUBLIC \"-//XXXXXX//DTD BatchReceiptAuthorization//EN\" \"http://dtd.XXXXXXX.com/dtds/ReceiptAuthorization.dtd\">
on each of the files at the very beginning - i.e within each transaction node , in the above structure, we need the above DTD string to be written. To do this, we added a java mapping as the second mapping after the message mapping that creates this string. Is this the right approach and would it produce what we are expecting ?

String sLine = null;
StringBuffer XmlMsg= new StringBuffer();
String Result,PayloadBody;
int indexOfFirst;
while ((sLine = reader.readLine()) != null) {
XmlMsg.append(sLine);
String StartingTag = XmlMsg.toString();
indexOfFirst = StartingTag.indexOf("<MerchantID>") ;
PayloadBody=new String(XmlMsg.substring(indexOfFirst));
Result=NameSpacePrefix.concat(PayloadBody);
output.write(Result.getBytes());
/* Thread.sleep(200000); */
}catch(Exception e){
myTrace.addWarning("Exception raised in the JavaMapping:modifyNamespace.java""\n The Exception Message: " e.getMessage());
throw new RuntimeException(e.getMessage()) ;
} public void setParameter(Map param) {
myTrace = (AbstractTrace) param
.get(StreamTransformationConstants.MAPPING_TRACE);Hi XI Gurus
In my scenario, I sent the inputstream that is being passed to the Java execute method - to trace and I see that the whole of the xml file - as shown below - which is the output of message mapping ( from the first mapping step ) in sent to the execute method of the java mapping a single call
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<Transaction> </Transaction>
<Transaction> </Transaction>
</ns0:Message1>
<ns0:Messages>
So, I modified Java mapping program to look for multiple occurences of <Transaction> tag and prefix them with my constant DTD Literal - which is the primary reason , why I had to use Java mappings after the message mapping.
Now, I get an error is XI- SXMB_MONI
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">

</SAP:Error>
Should I create multiple outputs - as many as the numberof target split files ( of type outputstream ) from the execute method in the java program ? -
Hi All,
After faceing so much of problem, i found that it would be better if i can go for an XSLT/java mapping:
1. It is adding an extra <b>ns0</b> to header line & end line which i dont want to be generated in the output xml file.
2. Namespace problem that basically sticking to 60 but i want 72 characters in my target xml file.
3. No carriage return at the end of each line which is not geting generated through graphical mapping.
Now i have an XSD provided by the client. So how can i use that and which mapping should best suits to solve all these problem.
Should i go for a java mapping or an XSLT/JAVA mapping.
I dont have any idea on both of them, So can you people send me the details for it.
Many Thanks & Best Regards,
JGD.Hi,
Based on the requirement and size we can choose the mapping.
If java is suitable to our requirement then we go for java.
If XSLT is suitable to our requirement then we go for XSLT.
Performance wise(high --> low) :
If data is less then
Graphical mapping -
> Java(sax parser)mapping -
> Java(dom parser)mapping -
> XSLT mapping -
> ABAP mapping.
If data is high then
XSLT mapping -
> Java(sax parser)mapping -
> Graphical mapping(internally it uses SAX)----> Java(dom parser)mapping -
> ABAP mapping.
If you choose XSLT then you can select Altova Map Force tool then no need to write the XSLT code here, it will automatically generates the code.

Hi Gurus
I wanted some inputs on Java mapping concept in SAP PI 7.0
I do not have a java background but my current project requires me to develop Java mappings in SAP PI 7.0 since the XML structure in the incoming files from the application are very complex and the timelines very tight.
Kindly let me know whats the best approach and how to go about it.
A sample of java mapping or the procedure will be extremely helpful
Also ly a pointer on what all to be as a prerequisite in Core java for the same
Please help

Java Mapping of Adapter-Specific Message Attributes
Hi!
I've got a problem with the help.sap.com-example for the above mentioned task:
DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create(
http://sap.com/xi/XI/System/File,
FileName);
String valueOld = conf.get(key);
if (valueOld != null) {
String valueNew = valueOld.replaceAll(input,output);
conf.put(key, valueNew);
The Container-class I have doesn't offer the method getTransformationParameters(). Additionally, the method get() from class DynamicConfiguration doesn't accept a DynamicConfigurationKey-object. Finally: how do I instantiate the Container-object (I think it's stored in the Parameter-Map, but what's its name?).
Thanks!

ChristianHi Christian,
Pls see these sap help links on the Java mapping.
http://help.sap.com/saphelp_nw04/helpdata/en/e2/e13fcd80fe47768df001a558ed10b6/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/43/09b16006526e72e10000000a422035/frameset.htm
As you would see in the example shown in the link...you donot require a container object in case of java mapping(that is required when you are using the user defined functions)...
here you can call the get() method from the map in the java mapping class....this map is set by the mapping runtime by calling the setParameter() method in your java mapping class.
Thanks,

Should we avoid Graphical mapping and stick with Java mapping?
After developing mappings in XI for a month, I just don't see any good reasons to use Graphical mappings over Java mappings. Maybe some experienced users here can give me some valid reasons why we should choose Graphical mappings. Here is what I think:
Disadvantages of Graphical mappings:
1. No way to perform automated unit testings. This is probably the biggest reason I hate it. You can do some tests manually when you work in Integration Builder. But there is no way you can write some unit testing utilities to automate the task.
2. Complexity. Even for some simple requirements, your Graphical mappings can become complicated and hard to understand. A lot of times, I find myself staring at several dozens of graphical nodes and try to understand what it does.
3. Impossible to reuse. This is totally against the DRY (Don't repeat yourself) principle. For example, to generate messages for JDBC adapter, it is common to have two identical fields for primary keys: one in the access node and another in the key node. If you change the mapping logic in one, you have to remember to change the other.
Advantage with Java mappings:
1. Fully automated unit testing. You can create JUnit tests along with your Java mapping classes and use Maven or other build tools to perform automated unit testing.
2. Your choice of XML parsing and binding. With Java mapping, you can choose any open source framework for XML parsing and binding. For example, with XMLBeans, I can convert XML input message to a Java object, transform to another Java object and write to output message. And each Java object is generated from its corresponding XML schema.
3. Highly reusable. We can use fundamental object-oriented designs to create highly reusable mapping components.
4. Better version control. Since the mappings are just Java classes, we can use CVS or SVN to track code changes.
5. Better build tools. We can fully utilize build tools like Ant and Maven to automate the build, unit tests, or even generate documents and mapping web sites.
So do you guys agree? Maybe I am still new to XI or I am missing some important things. But at this point, I just don't see why I should use Graphical mappings. Is there anyone developing XI interfaces completely with Java mappings?
Thanks in advance for any comments!

Could you explain more why the graphical mapping has better performance? I thought the graphical mapping is compiled into a Java class in the runtime anyway.
> Yes thats there, but same goes with Java mapping too
> right (if you haven't mentioned it as constants)
I mainly think about inheritance. If I have to build 10 interfaces and they all have some common behavior, I can create a base interface class to encapsulate the common logic. But with graphical mapping, you have to duplicate them in each interface.
> Disadvantages of Java mapping:
> 1. Performance
Same as above. I just don't see why Java has worse performance. I actually think Java should have better performance. You can optimize the code anyway you want. In some cases, you have to use queue functions in graphical mapping but it's not necessary in Java.
> 2. All might not be well versed with Java Code(though

I am not asking everyone to abandon graphical mapping. I am just wondering which one is better when you have skills for both.

You can create functions in Java too. All you have to do is to remember the function name.

Hi
Im following this blog http://scn.sap.com/community/pi-and-soa-middleware/blog/2014/09/12/html-form-upload-using-http-plain-adapter-with-java-mapping but I have encountered an issue which I cannot solve.
My issue is, in addition to the required output, I am also getting unwanted XML added, which originates from the Message Type in the source Service Interface,
i.e.
Content-Type: multipart/form-data; boundary=--ejjeeffe1
--ejjeeffe1
Content-Disposition: form-data; name="event"
Content-Type: text/plain
Import File
--ejjeeffe1
Content-Disposition: form-data; name="Filename"
Content-Type: text/plain
TestFile.zip
--ejjeeffe1
Content-Disposition: form-data; name="content";filename="TestFile.zip"
Content-Type: application/zip
Content-Transfer-Encoding: binary
<?xml version="1.0" encoding="UTF-8"?><__EmptyDoc></__EmptyDoc>
--ejjeeffe1
Any suggestions much appreciated.
Regards
SteveHi 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);

Java mapping for EDI order document
hi,
My project is to convert a EDI-850 Purchase Order Document using XI into an R/3 system.I planned t use java mapping So,I had got the java code necessary for the mapping from a tool called ALTOVA XML MAPRFORCE.
I have converted the code into a .jar file and put into the XI server.The mapping is working fine now. If i give an EDI order document as input to the mapping and test the mapping the out put is coming correctly.
Now i dont know what I should do in the Integration directory.
As I have to convert this document and post it in a R/3 system.I have found the function module to create a Purchase Order also "BAPI_PO_CREATE".
What should I do next ?Hi Mithun,
Follow the steps below:
1. BAPI is a RFC function module. So you import into Integration Repository. Then map your output to the structure of RFC.
2. In the integration Directory,
a. Create a business service representing your source.
b. Create a business system representing your R/3 system.
Before creating business sytem, first you need to register it as a techincal system and business system in sld.
c. Create a Sender Agreement to pick the message from source system. Depending upon the type of source system, you need to configure the sender adapter.
d. Create Receiver determination to route the message to the target system
e. Create interface determination to pick the current Interface mapping to convert source message to target message
f. Create Receiver Agreement to send the message to R/3 System. This should encapsulate Receiver Communication channel which is using IDoc adapter.
Reward if helpful.

please solve this issue.Uday,
May be you have uploaded class file into external definitions.
You need to Zip the class file into .jar and then upload into external definitions of integration repository
