Java Mapping in pi 7.1 using pi 7.1 nwds

I am writing a program to remove the special chars in NWDS Java mapping. this is for replacing the "&" with "&".. I am able to compile it and import the jar in PI.. but it does not do anything.. please check..
And also let me know where to check for Java mapping executed with trace detail.. to check if any error
          try {
          int read_data;
          while ((read_data = arg0.getInputPayload().getInputStream().read()) != -1) {
               if (read_data != '&') {
                    arg1.getOutputPayload().getOutputStream().write(read_data);
                    } else {
                         arg1.getOutputPayload().getOutputStream().write("&".getBytes());
          arg1.getOutputPayload().getOutputStream().flush();
          }catch (Exception e) { }

Dear Gopal,
If i not wrong you need to replace all the charecters "&" with blank ...
if so you can this code for doing that..
String outData = inData.replaceAll("&","");
or
you need to replace any special charecter to blank please clarify..
so that i can help you out to solve this issue using java mapping..
Regards
Vijay

Use java mapping class on PI 7.0

Hi experts,
I have a problem with a java mapping class on PI 7.0, maybe somebody could help me.
I have a java mapping that call a webservice using AXIS library. If I run on my PC the java mapping is working. I load on Imported Archive the Java mapping class and AXIS librarys. My Java mapping class is compilated by jdk 1.4.2.09, like others java mappings that i have on PI 7.0 system, but when I execute the interface, its returns an error:
Incompatible class versions (linkage error)
This error is caused by AXIS Libraries, I use AXIS 1.4 version, and I think that this version is using jdk 1.5 because I read it on some foros. Could somebody confirm it? If it is true, could somebody tell me if there are some AXIS version that use jdk 1.4 or maybe How could I solved it? Thanks.
Regards,
Gemma

Incompatible class versions (linkage error)
this is usually when the jdk version of XI server and the library version you used to develop the mapping are incompatible. Make sure you use the same version as of the server

Problem by adding attachments in Java Mapping

Hi,
we have to add some attachments in Java Mapping.
So we are using the Java Mapping API.
But it doesn't work correctly.
We got the following error in sxmb_moni:
Attribute Manifest ExampleAttachment is initial
So we checked what happened in the Manifest and in the SAP SOAP Envelope and we see that there is an inconsistence.
In the SAP Manifest we find the following entries:
<SAP:Manifest xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:wsu="http://www.docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="wsuid-manifest-5CABE13F5C59AB7FE10000000A1551F7">
     <SAP:Payload xlink:href="cid:payload-79a6e3c088db11dfa4dd0017a477c1e8<at>sap.com">
          <SAP:Name>MainDocument</SAP:Name>
          <SAP:Description/>
          <SAP:Type>Application</SAP:Type>
     </SAP:Payload>
     <SAP:Payload xlink:href="ExampleAttachment">
          <SAP:Name>ExampleAttachment</SAP:Name>
          <SAP:Description/>
          <SAP:Type>ApplicationAttachment</SAP:Type>
     </SAP:Payload>
</SAP:Manifest>
For us it seems the entry for our ExampleAttachment is wrong. I think there must be a real content id for the attachment like the cid for the MainDocument. In the SOAP Envelope you can find the following entry for the attachment:
content-type:text/plain
content-length:45
content-id:payload-79a6e3c088db11dfa4dd0017a477c1e8<at>sap.com
This is an example for an attachment!
--SAP_0017A477C1EC1DEFA3D200A5CB55CE04_END--
So here you can see a real content ID, but you can't find it in the Manifest.
So do we anything wrong in our source code or is it a bug of the SAP API?
Do you have any ideas?
Here the Java Mapping we're using for adding an attachment (as a test):

XSLT or JAVA Mapping

How to choose between XSLT & JAVA Mapping.

HI
Usually Java mapping is preferred when the target structure is relatively complex and the transformation cannot be accomplished by simple graphical mapping.
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.
Java mapping can be used when you have complex mapping structures.

Advantages of using XSLT mapping
XSLT program itself defines its own target structure.
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.
XSLT can be used in combination with graphical mapping.
Multi-mapping is also possible using xslt.
XSLT can be used with ABAP and JAVA Extensions.
Disadvantages of using XSLT mapping
Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
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.
XSLT mapping requires more memory than mapping classes generated in Java.
It all depends upon the required Scenario and the requirement , which mapping has to be used.

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...

> Hello guys,

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.
> 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 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.

PI 7.11 - How to create a System Error in SXMB_MONI using a Java Mapping

Hi
We ve go a Java Mapping in a File-to-HTTP Scenario. It works perfect except of one error case: if an empty source file or a source file with the wrong structure is delivered. In this case our Java Mapping forwards an empty payload to the HTTP channel. So, for PI is the mapping successful.
I'd like to recognize this case and invoke a system error in the SXMB_MONI, so that this mapping will be stopped and our alerting concept informs the users. I know, how to recognize the case in Java but need to know how to create the System Error Status in the PI System.
Thanks in advance
Michael

Hi Michael,
Please refer here for the mapping API description:
http://help.sap.com/javadocs/NW04S/SPS09/pi/com/sap/aii/mapping/api/package-summary.html
You can use the StreamTransformationException exception describet there to raise an error from your Java mapping. Direct link:
http://help.sap.com/javadocs/NW04S/SPS09/pi/com/sap/aii/mapping/api/StreamTransformationException.html
You might also consider using the "Empty-File Handling" option in sender file CC to avoid processing empty files by PI.
Hope this helps,
Greg

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?
Regards,
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

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

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 :If you have complex mapping in your scenarios and also some times if you have more than 100 field to map then better to choose the JAVA MApping
Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but, DOM is very processor intensive.
SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exactly easy to develop either.
DOM and SAX are APIs
In NWDS we have to develop the mapping and create jar and archieve and import it under Iported archieved in IR. this can be used in Interface mapping.

Using Container Object in Java Mapping

Hi All,
I need to use a Container object inside a Java Mapping, just like the one wich is used in the Graphical Mapping.
Here is the scenario:
I have an Interface Mapping with three steps on it.
The first step is a Java Mapping just to put some info in the Container. The second step is a XSLT transformation that uses an XSLT file to transforms from IDOC to xCBL. The third step is another Java Mapping that get the info from the Container and insert in the xCBL.
Does any one knows how to do it inside the Java Mapping Code? We cannot make modifications in the XSLT file because of some internal restrictions.
Thanks,

Hi,
If you make the container variable is a part of your message (input of Java Mapping) then you can access as normal fields.
Just have a look at these discussions-

Hope this helps,

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

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!

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.

Stefen
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.
