XML Structure Conversion using JAVA Mapping

Hi Experts,
I am having a requirement in which i want to convert the contents of source xml structure into a string and map it to the target field.
Source Structure:
<SRC>
<Node1>ABCD</Node>
<Node2>XYZ</Node2>
<Node3>1234</Node>
</SRC>
Target Structure:
<TRG>
<Node1>ABCDXYZ</Node1>
</TRG>
Both the source and target structures are in xml format only.....just the condition is that I have to use Java mapping to achieve it.
The contents of Source node Node3 are not to be mapped.
Since I have very less knowledge of Java it will be very helpful if you provide the complete code to me.
Thanks,
Abhishek.

Hello Udo,
Thank you for reply. It seems ABAP mapping is easier.
What do you think about the idea of using Value Mapping for such conversion task? In this case is it obligatory to use Java coding? And how about performance - will it be better than in case of ABAP mapping, can you say?
Thank you,
Igor

N:1 Mapping Possible using Java Mapping?

All,
Is it possible to do a N:1 mapping using Java Mapping?
If yes , how?
Reason for this question is that the execute() of the Java Mapping is going to take the source / request message as the InputStream . In the case of N:1 mapping , as we have multiple messages , how will they be send to the InputStream? Will both the messages be sent combined into the InputStream? Will the MESSAGES tag be embedded into the input stream?

Bhavesh

Hi @ll;
i try the same.
to conduct a java mapping with 2 input structures that fills one target structure.
This mapping is part of a Integrationprocess.
I tested the mapping at the Integration Repository (Interface mapping) with the structure given by henrique and it works fine without any error.
At runtime this structure looks like this (different prefix)
<?xml version="1.0" encoding="UTF-8"?>
<sxi:Messages xmlns:sxi="http://sap.com/xi/XI/SplitAndMerge">
     <sxi:Message1>
          <YOURXML1>...</YOURXML1>
     </sxi:Message1>
     <sxi:Message2>
          <YOURXML2>...</YOURXML2>
     </sxi:Message2>
</sxi:Messages>
As I put it in the Integrationprocess unfortunately a strange error arises.
The trace Workflow-Protocoll shows following error.
<Trace level="2" type="T">Call method execute of the application Java mapping com.endress.infoserve.xi.mapping.MergeConfigStore_IdocOrder </Trace>
<Trace level="2" type="T">Java mapping com/endress/infoserve/xi/mapping/MergeConfigStore_IdocOrder completed. (executeStep() of com.endress.infoserve.xi.mapping.MergeConfigStore_IdocOrder </Trace>
<Trace level="1" type="T">Parsing error after multi mapping.Expected Message<i> instead of IDOC </Trace>
I can't make head nor tail of it.
what´s the mistake?
can anybody please help me?
Thanks in advance
Kind regards

1:n Transformation using JAVA Mapping Scenario

Hi Frnds,
I done a scenario using 1:n Transformation Scenario using XSLT,Graphical Mapping.
But i want to develop scenario Using JAVA Mapping.
Can anybody done the same scenario using JAVA Mapping share the links..
Regards,
Raj Sekhar

You can use SAX parser for this
firstly create a StringBuffer sb object which will store our target output
when startDocument() gets called append the xml declaration in this method
sb.append("<?xml version=\"1.0\" encoding=\"utf-8\" ?>");
sb.append("<Root>");
next for the Test element you have your startElement() method called which will contain the name of your source tag i.e Test
for this , you will need to set a variable boolean isTest to true which was initialised as a false value.
in the characters method you will get the value present in this tag.
test the variable isTest for true value.
if it is true then append the following
sb.append("<Test1>"name"</Test1>"); //name is the buffer passed in characters method
sb.append("<Test2>"name"</Test2>");
sb.append("<Test3>"name"</Test3>");
at the end your endelement() will be called
here reset the value of isTest to false.
in your endDocument()
sb.append("</Root>");
lastly convert to byte[] and then to outputStream format

Dynamic file name while using java mapping

Hi All,
i need help.
I am using java mapping to convert xml file in zip file.
Now i need to set output file name as SiteId_TimeStamp.zip.
Site id is comping in xml file.
How can i do this?
I tried many thing but didnt get the solution..
As their is no message mapping so I am unable to use ASMA.
Please help.

Did you check the wiki? You just need to add the code into you java mapping..
Map mapParameters = (Map) transformationInput.getInputHeader().getAll();
   // a) Set Output File name
   mapParameters.put(DynamicConfigurationKey.create("http://sap.com/xi/XI/Dynamic",
                                                         StreamTransformationConstants.DYNAMIC_CONFIGURATION), "");
   DynamicConfiguration conf = (DynamicConfiguration) mapParameters.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
   DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
   //Depending on your requirement edit this logic. Here, NewDynamicName + CurrentDate will be output file name.
   DateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
   conf.put(key, ("NewDynamicName_" + dateFormat.format(new Date())) + ".pdf");

Query on processing a PDF file using Java mapping

Hi All,
i am trying to process a XML and PDF file using Java mapping, it is successful in XML but unable to do for PDF.
below is the code i am using... can any one guide me how to process PDF's..
byte byte1 = 0;
java.io.ByteArrayOutputStream bos = (ByteArrayOutputStream)outputstream;
while((byte1=(byte)inputstream.read())!=-1){
bos.write(byte1);
bos.close();
Thank You,
Madhav

Hi Madhav,
I think instead of going with JAVA mapping you can write a custom adapter module for it.

How to replace namespace tag with new value using -JAVA MAPPING

Hi Guys,
I need to replace namespace Tag in Target xml with a new value.
For Eg: My namespace Tag is - <ns0:TestHeader xmlns:ns0="http://0020.TestHeader.SS.com">
I want My target xml to have value- <ns0:TestHeader>
How can i achieve it using JAVA mapping?
Can you provide me the code to do so.

Sarjana,
Not well-formed XML is only possible by Java Mapping. Please use below replace logic in Java map.
inputContent.replaceAll("<ns0:TestHeader xmlns:ns0=\"http://0020.TestHeader.SS.com\">", "<ns0:TestHeader>");

RFC Lookup using Java Mapping program - Examples

Dear Experts,
I am working on a scenario which is using 1:N mapping. For deciding the target message I have to use RFC Lookup to call the backend ERP system and there are 2 ERP systems involved in this integration. As I am using Java Mapping and never did a RFC Lookup in Java. I kindly request you to give me some examples which I could use for my RFC calls in my Java Mapping. Simple example will do.
Client is adamant to use Java mapping, I could achieve this easily using XSLT or Graphical Mapping.
Advance Thanks,
Pradeep

Hello,
why don't you use Extended Receiver Determination Defining Extended (Dynamic) Receiver Determination - Integration Directory - SAP Library?
What you can do is create a Message Mapping between your source message and Receivers message type. In this message mapping you can use your RFC to generate the target message.
For example, lets say we have the function ZFM_GET_INTERFACE_INFO used to generate the List of Receivers given a source message. You could create a Message Mapping as below:
In this case, the RFCLookup box look as below:
The receiver determination configuration would look as follows:
Afterwards, you will need two specific message mappings for the two ERP systems.
Summarizing, you'll need:
1.- A Message Mapping: Source Message to Receivers Message Type (This one uses the RFC Lookup)
2.- A Message Mapping: Source Message to Target Message for ERP 1
3.- A Message Mapping: Source Message to Target Message for ERP 2
In Integration Directory you'll have 1 Receiver Determination(Source system, Target System determined Dynamically) and 2 Interface Determinations (Source System to ERP1, Source System to ERP2), etc.
I hope you find it useful.
Regards!

Splitting using Java mapping

Hi,
    I am working on a file to IDOC scenario.In the input file am getting data for multiple idocs.The file structure is such that in the sender communication channel am not able to identify the recordsets and hence cannot set the number of recordsets per message parameter,else would have generated multiple messages there itself.
   I want to implement java mapping.
   Can any one please tell me is splitting possible in java mapping, such that once the data for one idoc is over I will generate another idoc.
Thnx,
Pravesh Puria.

Hi Puria,
have a look to <a href="/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible without BPM - Yes, its possible!</a>. Instead of the message mapping use your java mapping. You have to build your result XML like:
<Messages xmlns:ns="myNamespace">
<Message1>
</MyFirstMessage>
</Message1>
<Message2> and so on

Udo

XML not well formed - Java Mapping, Webservice to RFC Scenario

Hello All Experts,
I have facing a strange type of error. I have written a Java Mapping which implements a DOM parser to take a request from a Webservice and validate it on the basis of some prerequisites. i.e. If data in the incoming request is valid, it creates a message of the same structure type as the input. If the incoming data is incorrect or incomplete; It generates an Error response structure.
When I run and test the same mapping program using Editplus Java editor for the error scenario; it executes perfectly and creates the correct error XML structure. (I checked it by importing the structure in the XI Message mapping test tab). But when I create jar of my java mapping program and test it in my interface mapping, it gives me "XML not well formed error" (Problem while building the tree).
Any idea as to why is it behaving in such a way? There are 2 reasons which come to my mind as of now:
1. The initilization of my input and output streams in the public static void main:
            InputStream in = new FileInputStream(new File("Input.xml"));
           OutputStream out = new FileOutputStream(new File("Output.xml"));
           validateXML myMapping = new ValidateXML();
            myMapping.execute(in, out);
The Output.xml has the xml structure for the correct case, do I have to initialize my outputstream for the error file? say error.xml
2. My Webservice interface is a sychronous interface (Request / Response) and output of the Java mapping program are two asynchronous interface. (I'll use a synch-asynch bridge when this works) - Is that causing a problem?
Please help.
Best regards,
Varun

Hello Varun,
it gives me "XML not well formed error" (Problem while building the tree).
I have come across the same error message while testing in interface mapping. My problem was when an exception occured in java mapping, the execution terminates with the messages XML not well formed error". In order to solve this issue what i did was catch the exception type TransformerException and in that catch block throw StreamTransformationException exception in main methos of mapping program i.e execute().
eg:-
catch (TransformerException e) {
               throw new StreamTransformationException("Can not write XML.", e);
By doing this you will see the exception raised , because some times when you execute your mapping with mail() method, though it create the file, when you try to open it will give error if any exceptions occured in mapping. By using the above notation you can handle those in java mapping.
Hope you have gone through this blog.

Message splitting using java mapping and BPM

Hi all,
I have a PLAIN FILE to IDOC Scenario.
We decide to use javamapping instead of message mapping because we have several hierachical structures.
We has more than one IDOC for file. And the mapping it's unable to detect the another header and create it at XI.
I had seen:
/people/michal.krawczyk2/blog/2005/12/04/xi-idoc-bundling--the-trick-with-the-occurance-change
"XI: IDOC bundling - the "trick" with the occurance change"
But the problem it's we doesn't use mapping programs, so we can't apply to this case.
So now i need to create a BPM scenario for resolve this issue. Anyone knows any example for split the income message and send any idocs to destination?
Thanks in advance,

IT WORKED !!!!
The only thing it's at out code line we must improve it in another way.
For everyone who needs to resolve, i copy the code line of the java mapping program.
The relationship is from the specific mapping for every scenary calling GenToHierMap.

Digitally Signing specific SOAP elements using Java Mapping

Hello SDNers,
Iu2019m having trouble creating java mappings to sign and verify digital signatures. Iu2019m new to Java so this is proving difficult. I understand the basic concepts of OO programming and utilizing classes/objects to build the program, but Iu2019m having trouble with the conceptual understanding of how I would like to get this done.
I have outbound and inbound messages. The outbound messages are originating from an ECC backend. The messages are processed through PI with a basic Message Mapping, then it is wrapped in a SOAP envelope with specific information using a XSL mapping and then I would like to use a Java Mapping to Digitally Sign specific portions of the entire message; specifically around an element in the SOAP header and sign the SOAP body. I also need to verify these sections for all inbound messages.
The simple pseudo code I have for the outbound messages is as follows:
<ol>
<li>1. read in xml (file input stream)</li>
<li>2. find the (specific information)</li>
<ol>
<li>a. assign that string to a variable</li>
<li>b. sign this variable with the security profile (keystore, private key)</li>
<li>c. e-write the variable into the main xml file</li>
</ol>
<li>3. find the soap body</li>
<ol>
<li>a. assign that string to a variable</li>
<li>b. sign this variable with the security profile (keystore, private key)</li>
<li>c. re-write the variable into the main xml file</li>
</ol>
<li>4. write the output file with both variables written (file output stream)</li>
</ol>
Currently Iu2019m using PI 7.1 so there is no more Visual Administrator tool.
Iu2019ve seen the examples from the last link, but I canu2019t seem to put it together when mixed with basic java mapping example. I have been searching the SDN forums for a while now, but hereu2019s my specific question: how do you create a java mapping to sign and verify specific elements of a SOAP message?
Thanks in advance,
Jason

Hi Jason, did you ever architect a solution for this?

Multi Mapping using JAVA Mapping 1:n Transformation--Urgent??

Hi,
I have to make a 1:n Mapping with the JAVA Mapping. The situation is as follows:
I have 1 ORDER with n positions and I have to convert this order to n ORDERS with 1 position in each order. My problem is, that I have to use the header-data of the input-order for each of the output orders and I have to use the first position of the input-order for the frist output-order the second postition for the second order and so on. Which mapping-steps do I have to use. I think this is an ordnary problem, but I could not find anything in the XI-help about this. Maybe anyon has got an idea.
Regards,
Raj

hi
The output from java mapping must look like
<Messages>
<Message1>
<Your Traget Order>....
</Message1>
<Your Traget Order>....
</Message1>
</Messages>
Create a Graphical mapping sample (1:N) to get an idea about this structure.
