DB Look Ups using JAVA Mapping

Hi Frnds,
I'm working one B2B Project, my question is,
I have to retrieve Order ,Order Response from one Data Base,
its already stored in DATA BASE as a CLOB Message.
I developed one JAVA Map to retrieve Order And Order Response.
its working fine,
But i made a connection through JAVA Map only,
But as Per SAP its not a good advice to perform Statefull operations through JAVA Mapping.
My Client not accpeting this approach.
what is the next way,
I performed some DB Look up using JDBC Adapter And Visula Admin.
But in this case its not a easy to retrieve the Order And Order Response.
Because in My logic there is 5 SQL Statements there.
Any one can provide Solution.
Thanks ,
Raj

Hi,
As you said, you have to run 5 sql statements and fetch Order and OrderResponse. Let's say all your inputs for these sql statements are A,B,C,D,E then these will be input parameters for Stored Procedure and out parameters will be Order and OrderResponse. Fetching logic should be in the stored proc.
By this approach you will get Order and OrderResponse in the Stored Proceedure response structure. That structure you can map to your Receiver structure. (if i am not wrong this is your aim)
You can see this sample blog on Stored Procedure scenario...

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

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!

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

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

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>");

Using RFC Look Up in Java Mapping

Hi All,
I need to do an RFC Look Up in a Java Mapping program. The response structure of the Function Module to be called consists of only one node called RESULT. In order to read the value exported by the function module in this export parameter RESULT, I am using the following code:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
factory.setNamespaceAware(false);
factory.setValidating(false);
Document docResponse = null;
InputStream in1 = result.getContent();
docResponse = builder.parse(in1);
String output = docResponse.getDocumentElement().getFirstChild().getNodeValue();
The function module works correctly and returns the expected result when tested in SE37. However, on running the above code, the statement docResponse.getDocumentElement().getFirstChild().getNodeValue(); always returns the value NULL and not the expected value that is actually returned by the RFC.
Kindly let me know where could I be going wrong.
Thanks in advance.

Hi Sreehari,
Your DOM code looks correct, it might be something with the overall code of java mapping. Just have a look at this blog /people/morten.wittrock/blog/2006/03/30/wrapping-your-mapping-lookup-api-code-in-easy-to-use-java-classes
and compare you code with it. See whether you can fine tune your coding to get the rigth response.

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

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.

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
