Doubt with Java Mapping

I have an interface that got a Java Mapping. This interface is from a non-sap system to SAP (xml to Idoc).
I have to change some stupid thing in the mapping, but the problem is that I dont know how can I do this.
I go to Mapping Objects\Imported Archives and I Export all files (lot of files) that I found in there. I gave them to a guy that knows about Java, and he said me that al those are class librarys, and there is no code in there so we can change it.
I cant do anything in message mapping because there is no mapping in there, and someone ask me if I can do something in BPM so we can do a simple mapping thing, but I think this is impossible (dont know why)
Maybe theres ir another way so I can get the original Java code to change the mapping.
Who can help me?

Hi Claudio
As suggested above you can use another mapping program that can change the target message generated by Java mapping you have into the target message you need.
To add more mappings you need to add them in Interface mapping in a sequence.
Moreover if you have only class files download a decompiler and decompile your java class to get the code
Hope this helps
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.

Problem with Java Mapping

Hello experts,
I developed a Java Mapping Programm for reading filename of a pdf file and giving filename to a rfc structure for calling a rfc module. Thus, I test it via testing interface method and implementing a main method in my mapping class, which works, but if I run it in the integration server I get the following exception:
MP: Exception caused of com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7: com.sap.aii.af.rfc.afcommunication.RfcAFWException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7
That is the execute method of my class:
     public void execute(InputStream inputStream, OutputStream outputStream)
          throws StreamTransformationException {
          // TODO Auto-generated method stub
          try { //The following is for the FileName in the File Adapter
               DynamicConfiguration dynamicconfiguration =
                    (DynamicConfiguration) map.get("DynamicConfiguration");
               DynamicConfigurationKey key =
                    DynamicConfigurationKey.create(
                         "http://sap.com/xi/XI/System/File",
                         "FileName");
               String myFileName = dynamicconfiguration.get(key);
               MappingTrace trace = null;
               trace.addInfo(myFileName);
               DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
               DocumentBuilder db = dbf.newDocumentBuilder();
               TransformerFactory tf = TransformerFactory.newInstance();
               Transformer transform = tf.newTransformer();
               Document docout = db.newDocument();
               Element root = docout.createElement("Z_SD_WEB_HP_INVOICE_STATUS");
               root.setAttribute(
                    "xmlns:ns1",
                    "urn:sap-com:document:sap:rfc:functions");
               docout.appendChild(root);
               Element docName = docout.createElement("IM_DOCNAME");
               root.appendChild(docName);
               Text srcxml = docout.createTextNode(myFileName);
               docName.appendChild(srcxml);
               DOMSource domS = new DOMSource(docout);
               transform.transform((domS), new StreamResult(outputStream));
          } catch (Throwable throwable) {
               throwable.printStackTrace();
If I test via main method and testing interface mapping the generated xml is like:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><Z_SD_WEB_HP_INVOICE_STATUS xmlns:ns1="urn:sap-com:document:sap:rfc:functions"><IM_DOCNAME>232132.pdf</IM_DOCNAME></Z_SD_WEB_HP_INVOICE_STATUS>
I do not understand why I get this error in real environment.

Hello experts,
I found the solution. I will also publish this solution, this is also a point which I sometimes missing here in this forum:
In creating the rfc-xml with java mapping, so a prefix should be add to the name of the rfc-structure e.g.
ns1:Z_RFC_CALL. If this prefix is missing, then you get this error:
com.sap.aii.af.ra.ms.api.RecoverableException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7: com.sap.aii.af.rfc.afcommunication.RfcAFWException: java.lang.StringIndexOutOfBoundsException: String index out of range: -7
To find this I create a grafical test mapping and I check the test rfc-xml with the java created xml.
Anyway thanks all for the published recommendations.
Kind regards,
Erkan

Help with java mapping

PI File adapter has a processing option u2018Empty-Message Handlingu2019 to ignore or Write Empty Files. In case there is no data created after mapping on target side then this option determines whether to write an empty file or not. But there is a catch to this option when it comes to using it with File Content Conversion which is described in SAP Note u2018821267u2019. It states following:
I configure the receiver channel with File content conversion mode and I set the 'Empty Message Handling' option to ignore. Input payload to the receiver channel is generated out of mapping and it does not have any record sets. However, this payload has a root element. Why does file receiver create empty output file with zero byte size in the target directory? Example of such a payload generated from mapping is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:test xmlns:ns1="http://abcd.com/ab"></ns1:test>
solution :
If the message payload is empty (i.e., zero bytes in size), then File adapter's empty message handling feature does NOT write files into the target directory. On the other hand, if the payload is a valid XML document (as shown in example) that is generated from mapping with just a root element in it, the File Adapter does not treat it as an empty message and accordingly it writes to the target directory. To achieve your objective of not writing files (that have just a single root element) into the target directory, following could be done:
Using a Java or ABAP Mapping in order to restrict the creation of node itself during mapping. (This cannot be achieved via Message Mapping)
Using standard adapter modules to do content conversion first and then write file.
can someone help with java mapping that can be used in this case?

     genFormat.execute(in,out);
     catch(Exception e)
     e.printStackTrace();
The code for PI 7.0 should also work for PI 7.1 provided you use the right jar files for compilation, but vice-versa is not true.
Could you please let us know if this code was useful to you or not?

Multimapping with java mapping

Hi,
i am trying to do multimapping with java mapping, but I am getting error "unexpected end-of-file" in SXMB_MONI.
for multimapping I have appended necessary code...
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
please suggest me solution.

I am creating 1:N multimapping and for that i have written 2 java programs, one consist of "execute" method and another "main" method.
and java code is:
public class Mapping_test implements StreamTransformation {
     private Map map;
     public void setParameter(Map param) {
          map = param;
     public void execute(InputStream in, OutputStream out) {
               try {       out.write( "<?xml version=\"1.0\" encoding=\"UTF-8\"?>".getBytes());
               out.write("<ns0:Messages xmlns:ns0=\"http://sap.com/xi/XI/SplitAndMerge\">".getBytes());
                out.write("<ns0:Message1>".getBytes());
                out.write("<ns1:FIN_GBO_AR_POSTING xmlns:ns1=\"urn:sap-com:AR_POSTING\">".getBytes());
                      out.write("<MS_GBO_Header>".getBytes());
                      out.write(("<SourceSystem>" + "FIS0045_FIS" + "</SourceSystem>").getBytes());
                      out.write(("<TargetSystem>" + "FIS0101_SAP_ECC" + "</TargetSystem>").getBytes());
                      out.write(("<InterfaceID>" + "sap"   + "</InterfaceID>").getBytes());
                      out.write("</MS_GBO_Header>".getBytes());
               out.write("</ns1:FIN_GBO_AR_POSTING>".getBytes());
               out.write("<ns1:FIN_GBO_AR_POSTING xmlns:ns1=\"urn:sap-com:AR_POSTING\">".getBytes());
                      out.write("<MS_GBO_Header>".getBytes());
                      out.write(("<SourceSystem>" + "FIS0045_FIS" + "</SourceSystem>").getBytes());
                      out.write(("<TargetSystem>" + "FIS0101_SAP_ECC" + "</TargetSystem>").getBytes());
                      out.write(("<InterfaceID>" + "sap"   + "</InterfaceID>").getBytes());
                      out.write("</MS_GBO_Header>".getBytes());
               out.write("</ns1:FIN_GBO_AR_POSTING>".getBytes());
                       out.write("</ns0:Message1>".getBytes());
                       out.write("</ns0:Messages>".getBytes());
catch(Exception e)
now I am getting error "unexpected end-of-file" mentioned above.
please suggest ..

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 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="">

Should I create multiple outputs - as many as the numberof target split files ( of type outputstream ) from the execute method in the java program ?

SOAP Adapter with JAVA Mapping.

Hi,
I am trying a scenario,
file->SOAP Receiver->SOAP Sender->IDOC
in this I have used two interface mapping(and two mapping also).
In first mapping i used Java mapping. so the WSDL of this is of no use for me.
and in second mapping graphical mapping is performed.
but my scenario is not woking completely. only one messge in SXMB_MONI is displayed. but it should be two. I think there is some problem in java mapping.
in java mapping i have generated XML output, which will be input of SOAP sender.
plaese suggest me the format which should be generated by java mapping.

Sandeep,
Let me try to put your requiremen,
You have 2 scenariom
FILE to SOAP
SOAP to Idoc
When the file becomes availbale, the Scenario 1 triggers of Scenario 2. Scenario 2 provides you a WSDL and so scneario 1 's output should be of the format of this WSDL.
Hope I am on the correct track.
If yes, just import this WSDL into your IR, and see the format in which it expects the data by using it as a message type in some mapping ( dummy mapping ) and then in your Java Mapping create a output of the same format, with the same namespace etc.

Bhavesh

Problems with Java Mapping in Bpm

Hello to All.
I have a simple scenario...
1) Receiver ( XML1)
2) Transformation
3) Sender (XML3)
I have 3 variables.
Variable 1 XML1
Variable 2 XML2
Variable 3 XML3
In my transformation have two source.. an XML and XML2 and my mapping program is java mapping.
The java mapping modify the XML1 according the XML2 and transform in XML3.
When I run BPM . I have problem , because the flow stop in transformation.

Yes I have tested. But I found the solution.. The java mapping generate a header like <xsi : Message1></>... <xsi : Message2> </>
Thanks.

Doubt with Performace mapping in RWB

Im making a performance documento for each interface.
but i cant understand whats meaning of Consolidated Data.
i could see if Consolidated Data is checked the result is diferent that it s not. so i decided look at SAP help. i found an explanation about its, but still it is no clear.
Sorry my poor english

Test RFC destination AI_RUNTIME_JCOSERVER. You may delete and recreate it.
how exactly do I test it? in the XID or the SAP DEV?
how can I delete and recreate?
since I never did it, details will be appreciated.

Java Mapping for HTTP Post

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
Steve

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);

JAVA Mapping

Hi,
I have worked on Graphical mapping and XSLT Mapping. I want to do some scenarios using Java mapping. Can anyone give the detailed steps to work on Java Mapping. What are the softwares needed and their configurations. Also I want to know whether NWDS is compulsory to work on Java Mapping. Thanks.
Regards
Suresh

Hi,
Its not necessary that NWDS is compulsory to work with Java mapping.
for java mappings you need jar file.
Just have a look at these links for mapping:

When do we go for ABAP mapping and Java mapping

Hi friends,
At present I am working on graphical mapping in XI ,can you guys give me with an example or scenario when do we use ABAP mapping , Java mapping or XSLT mapping.
Thanks in advance
Sud

I have standard XSLT mapping programs available for my scenarios, so use XSLT mapping. Similarly with Java mapping, For most scenarios, message mapping does the job too well. Abap mapping similarly is used to leverge existing ABAP base. If message mapping becomes confusing and hard to follow with too many functions, I go for Java mapping (just my way). I havent used ABAP mapping thus far.
Discussing ABAP mapping
ABAP mapping is developed in ABAP work bench. ABAP mapping needs to be transported to integration server and XI does not support this transport and have to do with ABAP transports.
Customers who can develop mapping program on SAP web AS and can transport them there can use ABAP mapping
*ABAP mapping programs cannot access the value table
*Since ABAP mappings are executed on ABAP stack SAP does not provide any ABAP mapping programs
*ABAP mapping programs must exists with one single version in IS, unlike JAva and XSLT mapping that can have multiple versions of mapping program

any one could help how to write the Java mapping , am able to get the data from local folder , but error getting as a message mapping error, there is no key field values for in this message.
Probably it should be happen with Java mapping, actually I am from SAP SD back ground, can understand the ABAP.
Warm regards,
kumar.

Hi,
I think file adapter is sufficient for you. Dont need any java mapping. Refer to the file adapter content conversion for sender. Identify the key fields for heading, messages and footer. Then define record set with repeating structures in it like head,1,msg,*,footer,1.
This should solve the problem.
