Java Mapping in NWDI.

Hi experts,
I want to develop a Java Mapping in NWDI for SAP XI 3.0. To do this, I need to use the library aii_map_api.jar the J2EE Engine of SAP XI. To use the library in the DC's created in NWDI, I need to define the dependencies with the SCA that contains this library.
What is the SCA that contains this library? Is SAP_XIAF?
Thanks,
Jose.

Hi Jose Maria,
up to PI 7.0 (including XI 3.0), XI Java libraries were not actually developed internally using NWDI.
So, you'll not see the .SCAs containing a "BUILDARCHIVES" folder (which is usually where the Development Components are included when you create a SCA from DI), but just the "DEPLOYARCHIVES" folder (which just contains the runtime built classes).
Starting from PI 7.1, the XI SCAs contain the Development Components (because they've started to be developed on DI).
So, for you to be able to work with PI 7.0 libraries in DI, you'll need to create a Development Component of the Library type and add the .jar you want to use to a public part in that DC. Then, in the DC where you'll include your code, you must refer to that Library DC/public part. Library DCs are not included in the deployable SCAs, when you build your project, so there's no possibility of duplicated .jars in your server when you deploy your application.
Check this out for more info in creating a Library DC: http://help.sap.com/saphelp_nw04s/helpdata/en/29/2756405aff1e24e10000000a1550b0/frameset.htm

Get dynamic filename in a Java Mapping (NOT UDF)

Hi,
we are using a Java Mapping step in XI (not UDF). We need to have access to the filename. In the File Adapter we set the message attributes and can see the filename value in the SXMB_MONI.
We use the following code fragment to have access to the filename:
Container container = new Context(new FunctionWrapper(0));
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String sourceFileName = conf.get(key);
This doesn't work. We think the declaration of the container class is wrong. Does anybody have some information about using the dynamic attributes in Java Mappings?
Thanks in advance
Michael

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,

I'm having some troubles doing the mapping through java mapping in PI.
I've done the java class in the SAP NWDS and imported it on PI through the ESR.

Am i doing anything wrong in the code? Where can this nullpointerexception be triggered?
Thanks.

These three xml are the same:
<?xml version="1.0"?><a:xml xmlns:a="urn:123">root</a:xml>
<?xml version="1.0"?><xml xmlns="urn:123">root</xml>
<?xml version="1.0"?><ns0:xml xmlns:ns0="urn:123">root</ns0:xml>
But your code will work only with last one, because it doesn't bound namespace to prefix ns0.

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..

Linkage error while doing java mapping

Hi,
I Have written a java mapping but when i use it in xi.It is showing an error as linkage error
LinkageError at JavaMapping.load(): Could not load class: com/satyam/nestle/JavaMap
Can anyone explain what does this mean and how to overcome it.
Thanks in advance,
Bhargav

Did you try testing the java mapping seperately....that it does not have any errors??? Also check the cahce update. Sometimes it happens that XI is not able to load the class file from the cache. Perform a CPA cache refresh (delta). This should solve the problem
Reward if helpful.

Issue in conversion ABAP to java mapping during PI upgrade

Hi All,
We are upgrading one interface from ABAP mapping to Graphical/Java mapping in PI upgrade.(7.1 dual stack to 7.4 version)
In ABAP mapping there is character conversion like below.
encoding = '1164'
replacement = '?'
We want to implement the same functionality either through Java or graphical mapping . But we are not sure what are the range of characters that need to be converted to '?' and also what is the most optimized way to achieve this functionality.
Below are few sample of characters coming in the file:
б,л,к,У,М,л,и,о,ф..etc

hi all,
the issue got resolved with a JAVA replace function
String r = str.replaceAll("\\P{InBasic_Latin}", "?");
Thanks all for your inputs.

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
ilka

hi 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";

Keystore access in Java Mapping Program - user J2EE_GUEST

Dear Gurus,
I have the following problem:
I need to validate the digital signature of a XML document and I'm using some examples provided by SAP as follows:
          InitialContext ctx = ctx = new InitialContext();
          Object o = (Object) ctx.lookup("keystore");
          KeystoreManager manager = (KeystoreManager) o;
          KeyStore ks = manager.getKeystore("Serasa");
{/code}
But I get the error below, saying that user J2EE_GUEST is not authorized. How do I change the user who executes java mapping, because I granted permissions in Visual Admin to another user.

Thank you very much

Hi Fabio,
first of all have you checked if standard functions to verify digital signature for pi adpaters would work for you?
We have used the following code to access the Keystore in a custom adapter. It accesses the keystore with the access rights of a JEE application (it has a reference to the sample adapter "sap.com/com.sap.aii.adapter.sample.ra"). Check out if it works in your mapping, too.

Need help on guide of java mapping

HI,
I want to learn java mapping. I searched in blogs but I am not comfortable to understand. Can anyone explain me the step by step process.
Thanks,
Enivass

Hi enivas,
Having basic understanding about J2SE will be great help for you. Please check these links about Java Mapping step by step

SAP PI Java API has changed a lot from PI7.0 to PI7.1. http://wiki.sdn.sap.com/wiki/display/XI/UsingPI7.1APIforJavamapping
Check them out in this link Javadocs Index http://www.sdn.sap.com/irj/sdn/javadocs. Blogs mentioned use old API, but once you get idea about Java mapping switching to new API will be easy. Java help is easily available on net, use Google more. Happy learning.

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.

Problem in Java Mapping

Hi,
      I was trying out a simple Java mapping example.
Example of source structure is -
<?xml version="1.0"?>
<ns0:MT_SRC xmlns:ns0="http://www.sap-press.com/xi/training/00">
<organization>
<employee>
<firstname>Jack</firstname>
<lastname>Rose</lastname>
</employee>
<employee>
<firstname>Paul</firstname>
<lastname>McNealy</lastname>
</employee>
<employee>
<firstname>Vaibhav</firstname>
<lastname>Pandey</lastname>
</employee>
</organization>
</ns0:MT_SRC>
Example of target structure is -
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_TRGT xmlns:ns0="http://www.sap-press.com/xi/training/00"><Organization><employee><name>JackRose</name></employee><employee><name>PaulMcNealy</name></employee><employee><name>VaibhavPandey</name></employee></Organization></ns0:MT_TRGT>

However, when I'm testing my Interface mapping, I'm getting the following error -
Call method execute of the application Java mapping com.mapping.JavaMap
Error during appliction Java mapping com/mapping/JavaMap
java.lang.StringIndexOutOfBoundsException at java.lang.String.getChars(String.java:672)
Could anyone please help me out with this?
Thanks and Regards,

HI,
It looks to be that your JavaMap class have one field whihc will be not getting the proper value as input thus its creating the array Index out of bound exception.
Please can you verify if you have assigned the proper String size for all the fields.
Or probably you are getting the blank value which have created the execption.
Also can you narrow down and let me know about the line String.getChars(String.java:672)
Here you have used the try and catch option but may be the exact line no. can give better idea about the problem.
Thanks
