Problem in Uploading Java mapping Code

Hi Guys,
I never work on Java mapping before, i got the code required for my progrmme in these forums.So i saved it as a text file. now i want to import that fileintomy programme as Java class. i think i have to use Netweaver Studio. what exactly i have o do it.
Thanks in advance.

Hello Kartik,
If your code is handling the Required Mapping.Then what is you need to do is :
Create the Jar file using any Java IDE (or) use Netweaver developer studio.
Before creating the u201Cjaru201D file just make sure that the "path" of the class file in the imported archive. It should be the
same as your "package" path.
Once the class file is created, we have to create the jar file with all the necessary files. After creating the jar file, it
has to be deployed to XI.
Import the Jar file using Imported Archive in IR under Mapping Objects.
See this blog it explains how to load :
Java Mapping (Part III)
After doing the necessary setps you can test the Mapping.

Editing JAVA mapping Code

Hi Experts,
Need your help in editing the JAVA mapping code...I know it would be done by some external tool like Eclipse, netweaver studio..I just need to make a small change in the code and reimport the same in PI mapping.
Can someone help me in providing the steps or an easy way of editing the JAVA mapping archives.
thanks

Hi Smith,
Java mapping code will be bundled in Imported Archive (Imported Archive will contain .class and .java(optional) files). Download imported archive file (zar file)to local disk.
If .java file is not available in Imported Archive :
Open .class file with Java decompiler and copy code to project in NWDS or Eclipse tool and do required modifications
If .java file is available in Imported Archive:
copy .java code to project in NWDS or Eclipse tool and do required modifications .
Thanks
Hari.

Problem in SAX Java mapping

Hi,
I'm using SAX Java mapping in one scenario. Problem is when I get some Croatina characters, like Đ or u0160,
output XML is not valid. XML Spy complains, IE complains and so on. Customer is sure that data ( XML in CLOB field in Oracle DB) is UTF-8? What could be a problem?
What I'm doing is reading entire XML into string with help of BufferedReader, then do some manipulation and write String into byte array with:
               byte[] bytes = file.toString().getBytes("UTF-8");
               saxParser.parse(new ByteArrayInputStream(bytes), handler);
and then of course parse XML. readLine method reads data and problematic is "Ä�" - ￯0 - 0xC490.
For this character XML Spy doesn't complain, IE also. After conversion, this character looks like "Ä?" - 0xC43F, and this is not good any more. Why?

Hi Stefan,
I've finally done it. Code as foollws:
     public void execute(InputStream in, OutputStream out)
               throws com.sap.aii.mapping.api.StreamTransformationException {
          DefaultHandler handler = this;
          SAXParserFactory factory = SAXParserFactory.newInstance();
          try {
               SAXParser saxParser = factory.newSAXParser();
               fStreamOut = new BufferedWriter(new OutputStreamWriter(out, "UTF-8"));
               encoding = "UTF-8";
               if (map != null) {
                    mappingTrace = (MappingTrace) map
                              .get(StreamTransformationConstants.MAPPING_TRACE);
               InputStreamReader is = new InputStreamReader(in, "UTF8");
               BufferedReader reader = new BufferedReader(is);
               StringBuffer file = new StringBuffer();
               String line = new String();
               try {
                    while ((line = reader.readLine()) != null) {
                         file.append(line);
               } catch (IOException e) {
                    e.printStackTrace();
               } finally {
                    try {
                         in.close();
                    } catch (IOException e) {
                         e.printStackTrace();
               Date d4 = new Date();
               file = replaceREGEX(
                         "<\\?xml version=\"1\\.0\" encoding=\"UTF-8\"\\?>", "",
                         file);
               char[] cArray = file.toString().toCharArray();
               Date filedat = new Date();;
               SimpleDateFormat df = new SimpleDateFormat("yyyyMMdd_HHmmss_SSS");
               String fName = df.format(filedat) + "_El_Invoice.xml";
               Writer out1 = new BufferedWriter(new OutputStreamWriter(
                         new FileOutputStream(fName), "UTF8"));
               try {
                    out1.write(file.toString().toCharArray());
                    out1.close();
               } catch (UnsupportedEncodingException e) {
               } catch (IOException e) {
               saxParser.parse(fName, handler);
               File outFile = new File(fName);
               outFile.delete();
          } catch (Throwable t) {
               if (mappingTrace != null) {
                    mappingTrace.addInfo(t.toString());
               t.printStackTrace();
problem was also in method for writing in output stream, so I've changed it:
     private void printOutPut(String sOP) {
          try {
                  //    fStreamOut.write(sOP.getBytes());
               fStreamOut.write(sOP);
          } catch (IOException e) {
               e.notify();

Java Mapping Code

Hi....
I have done java mapping using file to file scenario....
I have created two data types, two message types, two message interfaces... in imported archives i have imported
dom4j-1.6.1.zip and itext.jar files..
i have written my java code like this:
package com.xmltopdf;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import com.lowagie.text.xml.XmlToPdf;
public class MyXmlToPdf {
     public MyXmlToPdf(String inputFile, String outputFile){
               try {
                    XmlToPdf xtp = new XmlToPdf();
                         System.out.println("Ravi");
                    xtp.parse(new FileInputStream(inputFile), new FileOutputStream(outputFile));
               }catch(Exception e ) {
                    System.out.println(e);
in message mapping i have invoked "MyXmlToPdf(String,String) constructor like this:
MyXmlToPdf xmt= MyXmlTOPdf("C:
source
filetofile.xml","C:
source
file.pdf");
return "";
and i have configured my communication channel, reciever determination, sender aggrement, reciver aggrement, and interface determination.....
so please tell me whether my code is correct or not... if its correct why i am not getting the pdf file.. if its not correct please tell me whats wrong in my code...
Thanks & Regards
Ravi Shankar B

Hi Ravi,
Normally Java mapping is used to convert an source XML message to target XML message.If your requirement is to generate a PDF file for the source XML try to write a File adapter module at the receiver end to do this job.
The problem could be your File path. Please check the following:
1. Did you check your source file C:\source\filetofile.xml is available in <b>XI server</b>?
2. Try to give the filename like this : <b>C:/source/filetofile.xml</b>
Please let me know if u need further help.

Ananth

Problems with a Java Mapping

Hi Experts,
as part of my diploma-thesis I have to write a java SAX-Mapping, which mapps the following incoming message:
mt_MappingOUT
             set
                 set_Element_01
                 set_Element_02
                 set_Element_03
                 set_Element_10
to the following outgoinig message:
mt_MappingIN
              TABLE
                    item
                        item_FIELD_01
                        item_FIELD_10
I develped the following code, which unfortunately results in "XML is not well defined" while testing. Unfortunately I cannot find the problem. So I hope someone of you can have a look an will have an idea.

Hi Ravi, hi Raman,

Java Mapping problem...

Hi Gurus,
I am using the Java mapping in my XI system and it works fine in my Development.
I just moved all my objects in to QA and I am getting some problem in my Java mapping. It is not behaving like the dev the output format.
Is their anything have to do for Java mapping while importing in to the QA system.
I did the file transport and imported in to my QA.
Please give me your comments and solution to resolve this issue.
Thanks,
Jane.

Handling Character Entities - Java Mapping Issue

Hi Experts,
    I need to replace the character entities in my input XML. But, the problem is the java mapping I've written isn't replacing the character entities as expected. For example if my input XML contains <NAME>&><XYZ</NAME>, then the ouput is <NAME>&amp:&gt:<0001&lt:/NAME>, whereas it should be <NAME>&amp:&gt:&lt:0001</NAME>.
Note: I've used : instead of ; just to show it properly SDN.
Can any of you share the code for the same if you've used it already?
Thanks a lot in advance.
Regards,
Hussain.

Hi Pooja,
    Thanks for your prompt reply.
Are you trying to use the java mapping just to handle the character entities or your interface itself only has a java mapping?
               - I'm using Java Mapping just to handle the character entities. Say my input XML looks like
<?xml version="1.0" encoding="UTF-8"?>
<resultset>
<row>
<ID>&<1</ID>
<MESSAGE><![CDATA[<?xml version="1.0" encoding="UTF-8" ?><LGORT>&<0001</LGORT>]]></MESSAGE>
</row>
</resultset>
I need to replace &< in <ID> to &amp:&lt: and similarly for CDATA <LGORT>&amp:&lt:0001</LGORT> before I process it in XI. In my java mapping I read the whole XML as string (line by line as mentioned below) and try to replace the character entities using some logic, which isn't working properly.
StringBuffer buffer = new StringBuffer();
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
for (String lineRead = reader.readLine(); lineRead != null; lineRead = reader.readLine()) {
       buffer.append(lineRead);
I've also checked the thread mentioned by Srinivas. But, StringEscapeUtils.escapeXml() would replace all the character entities like &lt:?XML... , which would result in an invalid xml...
Please suggest.
Thanks,
Hussain.

Java Mapping with CDATA

One simplest way is read the data element value as the string and ignore first six or seven characters by using substring method or so... Use the return value string for parsing the values from respective tag element using parser or manually

Hi Xinaxu,
Here is the java mapping code.
public class Cdata implements StreamTransformation{
     public static void main(String[] args) {
          try{
               Cdata genFormat=new Cdata();

               FileOutputStream out=new FileOutputStream("C:\\Apps\\acm\\cdata1.xml");
               genFormat.execute(in,out);
               catch(Exception e)

XI AF API call failed. Module exception: Java Mapping

Hi Experts,
I have faced a typical error for one of my interface. The Scenario is SOAP to SOAP and we are performing SOAP Lookup before sending the data to Target web service. We are using one Java Mapping 'FileIns_lookupLoad.java --- com/fi/' and performing the SOAP Lookup from within the code. In the Lookup Communication channel we are using 'Axis' as message protocol and passing couple of values through Module Key parameters. We have same ESR and ID objects in Development, Quality and Production (as per Version ID and History).
Now the problem is Lookup is failing only in Development but Quality and Production is working fine. I have replaced Quality CC URL with the development WSDL URL, but that worked fine. That means Development Web Service is good. We are getting the below error in Dev:
<SAP:Stack>StreamTransformationException triggered by application mapping program com/fi/FileIns_lookupLoad; Look Up Failed</SAP:Stack>

I have already checked with Basis and as per them JDK and Java versions are identical in Dev, QAS and Prod. It seems something is wrong with 'XI AF API' which we are calling from the channel. If we totally ignore Lookup process and send direct data, it is working fine. Target CC is also using Axis.
Sequence in CC: afreq ->xireq ->wssec2 ->xires ->afres
For any more information please let me know.
Thanks,
Nabendu.

Regarding Java Mapping

Hi,
I am new to java mapping. I just want to know what files I have to upload in IMPORTED ARCHIVES in Integration Repository to run the mapping properly.
Thanks In Advance.
Yaseen.

Yaseen,
If you are calling some class that is no a part of the standard jdk, then you need to have those classes / packages available under imported archives.
<i>I dont think so when I upload only class file, it says class not found.</i>
Compile your JAVA Mapping code , create the class file and then import that clas file under Imported Archives and use the same for mapping program in interface mapping.
Like i mentioned, if you are using some class in the Java Mapping that is not a part of stanadrad jdk, then you need import those Packages also.

UDF in message mapping instead of Java Mapping. Pls advice urgent

Hi All,
My scenario
CRM --- XI -- CRM
In XI I have to open socket connection.
Pls refer link:
/people/saravanakumar.kuppusamy2/blog/2005/12/15/socket-integration-with-xi
Can Java Mapping code given in above link for socket connection can be used in Message Mapping (CRM -- CRM)UDF?
Pls advice urgent
Regards

Hi Henry,
I understood your requirement.
But as per the architecture of XI/PI some message has to trigger your scenario.
In this case there is no adapter where you can directly communicate with CRM system.
Do one thing configure a dummy scenario on the sender side.
Use File adapter for simplicity. once it pools the file with some dummy data in the file it comes to Interface mapping(message mapping) of the PIPELINE steps. Now use the code as you mentioned above(within UDF) for opening socket to CRM system and implement you business logic within that program and write the response to target interface which will infact talk with CRM system.
Dont forget to do the coding in an infinite loop with some delay (if required). Other wise every time you have to put a message for File Adapter for triggering purposes.
You can also acheive the same if you use Java Mapping instead of Graphical mapping with UDF(code for Opening socket and business logic). I suggest you to use Java Mapping.
I dont know how you will comunicate with CRM system on receiver side.?
Thanks,
Gujjeti

Java Mapping with an xml array as input

Hi Gurus,
I have to perform a java mapping to map some input xml contained in an array with a target message type. I have found a good java mapping example here:
Re: Please provide Java Mapping example
but my mapping input is not a single XML, but an XML array, thus I have a doubt...
How can I map multiple XML contained in an array with a target XML? I have to solve this problem into a Java mapping prospective.
Thanks to all!

Hey Stefan, I think he is refering to a n:1 multimapping.
If that is indeed the case, Gabriele, you will have to consider the initial tags inserted by mapping runtime to treat multimappings.
Suppose your XML message is like
<myMT xmlns="urn:mynamespace">
<value>xpto</value>
</myMT>
Then, if your source message interface occurrence is defined as unbounded in your interface mapping, your mapping program (message mapping, xslt, java mapping, whatever) will receive, from mapping runtime, a message like this:
<Messages xmlns="http://sap.com/xi/XI/SplitAndMerge">
<Message1>
    <myMT xmlns="urn:mynamespace">
      <value>xpto1</value>
    </myMT>
    <myMT xmlns="urn:mynamespace">
      <value>xpto2</value>
    </myMT>
    <myMT xmlns="urn:mynamespace">
      <value>xpto3</value>
    </myMT>
</Message1>
</Messages>
Also, if you have more than 1 message type as source of your interface mapping, your mapping program will receive the other message types in <Message2>, <Message3>... tags.
The <Messages> and <MessageX> tags will always be automatically generated by mapping runtime when dealing with multimappings, which are mappings from m XML messages to n XML messages, with either m, n or both different of 1 (note that this definition includes mappings from 1 type to 1 type, when either source, target or both message types have max occurrence = ubounded).
Finally, remember that the output that your mapping program generates will also have to include these <Messages> and <MessageX> tags (with proper namespace), since mapping runtime will be expecting them. Message mappings treat those by default, but your xslt and java multimappings will have to explicitely include these tags in the output.
Regards,
Henrique.

Regarding Java mapping and ABAP Mapping

Hello,
If I suppose to do Java mapping or ABAP mapping, Is there any pre requisite to perform these two mappings?
If exist what they are?
How to perform them?
Thank you

Hello jyotsna,
Java mapping can be used when you have complex mapping structures.
We can do most of the times for our requirements through Graphical mapping.
When the structures are very complex to build you can go for SAX (Simple API for XML) or DOM (Document Object Model) parsers.
Message mapping internally generates DOM parser.

ABAP mappings run on ABAP Stack and are developed in the ABAP workbench of the Integration Server.
You normally do not need to use the ABAP mappings and is preferable for someone with ABAP programming background. I should say JAVA functions would suffice any complex scenarios.

You need to provide the name of your mapping program maually , you see it is an input box.
just provide the name of abap mapping program it will work.
and one more thing you cannot test abap mapping program in integration builer you need to test in abap only.
use tcode: SXI_MAPPING_TEST for testing abap mapping
