Java mappings ?

Hi,
I need some information regarding java mappings in IR.
How to Test and Debug Java Mappings?
Thanks in advance,
siva.

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

RESOURCE_NOT_FOUND for XSLT and Java Mappings (SXMB_MONI)

Experts,
I need your opinion / experience about a problem that we have been facing here:
XI 3.0 was upgraded to PI 7.0, but since then all interfaces that uses XSLT and Java Mappings throws a RESOURCE_NOT_FOUND error in SXMB_MONI only in the production environment.
We found SAP Note 951318 that describes exactly the scenario we have here. The note also inform that the issue is solved at SP 07 (for PI 7.0).
The problem is that we find out that abap and java instance are with different SP ( SP 13 for abap and SP 09 for java) after XI upgrade to 7.0, since they had a error at java instance.
Have anyone of you facing with this problem?
I believe that even having a SP greater than 07 (as sap note 951318 requires), as we have an difference between abap and java SP, this issue might have been causing the problem.
Points will be given.
Regards,
Daniela

Yes, thats true. As you can see,
In XI 3.0 (SAP Netweaver'04), the issue is solved in:
           SP 18,
           SP 17, patch 1 (archive SAPXITOOL17_1. sca for XI Tools)
           SP 16, patch 4 (archive SAPXITOOL16_4.sca for XI Tools).
you need to import and put a patch if you are using XI 3.0. but in your case it is PI 7.0.
So please check out the SAP Note : 950608 and download SP 07,patch 2 (archive SAPXITOOL07_2.sca for XI Tools).and Note 952402 .

Creating java mappings

Hi Experts,
Is there any tool available for creating java mappings in XI given a source and target message. I have seen for XSLT mappings there is a tool called stylus studio, which has some kind of graphical tool to create the XSLT mapping between a source and target XML message.
thanks
sankar

Hello Sankara,
The message mapping tool is aimed for that. When the mapping is drafted using this tool and executed it internally creates a java program corresponding to the mapping, which then gets executed.
Thanks & Regards

How to get Message IDs in Java Mappings

Hello,
in PI 7.1 Java mappings the way of getting the trace object has changed from:
trace = (AbstractTrace) param.get(StreamTransformationConstants.MAPPING_TRACE);
to:
getTrace();
Because the Java mapping class definition changed from
implements StreamTransformation
to
extends AbstractTransformation
Is there something similar to get the message ID or do i have to use the old way:
public void setParameter(Map param) {
     this.param = param;
     if (param == null) {
          this.param = new HashMap();
String MessageID = (String) param.get(StreamTransformationConstants.MESSAGE_ID);
Thanks and best regards,
Benjamin

I found an easyer way:
TransformationInput.getInputHeader().getMessageId();
But your reply brought me on the right track!
Thanks.

JAXB as standard API for Java Mappings in XI?

Hi there,
Has anyone on this forum implemented Java mappings in XI using JAXB (reference implementation for XML/JAVA data bindings of SUN)?
If Yes, can you please share any experiences?
We're considering to use this API for Java Mappings in XI but first would like to get more background info.
Cheers,
Rob.

Hi Roberto,
Have tried implementing Java mapping using JAXB technique couple of years ago. However I was not able to test the mapping in XI/PI environment.
<ul>
<li>There is no in built support for JAXB from SAP XI.</li>
<li>There is no documentation available from SAP on JAXB hence it is difficult to implement the mapping.</li>
<li>We have to import JAXB specific jars along with the mapping code. my attempt to execute the mapping test in IR tool was unsuccessful It was running fine in standalone mode in local PC </li>
</ul>
[My question on SDN on same topic..|Java Mapping Using JAXB [Java Arch for XML Binding];
Thanks and regards,
Ananth

"java Web Service from WSDL" just hands me a SOAPElement, no java mappings

Another beginner question. I've used jdev and built a WSDL starting from a somewhat complex xsd. I've used the wizard "Java Web Service From WSDL" taking defaults. It seems to correctly generate class files for all my xsd types. It produces a fancy looking java-wsdl-mapping.xml But the generated stub service implementation just gets handed a SOAPElement object. Why generate all that mapping stuff and then make me parse the incoming data myself with SOAPElement methods? How am I supposed to make use of the mapping work that the wizard seems to have done for me?
Thanks,
Steve

Dear Tugdual,
Thanks for your intrest in my issue. I narrowed it down to the following type in my xsd
<complexType name="PersonInfoType">
<sequence >
<element name="FamilyName" type="string"/>
<element name="IndividualName" type="string"/>
<element name="SpouseName" type="string"/>
<element name="BirthDate" type="dateTime"/>
</sequence>
</complexType>
This works fine - the "WebSerice From WSDL" wizard "knows" how to generate a class for PersonInfoType (with geters and seters) as well as useful stub implementation:
public class PersonInfoImpl {
public PersonInfoType processPersonInfo(String entityCode) {
return null;
However, if I make my type multiple occuring (to represnt e.g. rows from a db)
<complexType name="PersonInfoType">
<sequence maxOccurs="unbounded" >
<element name="FamilyName" type="string"/>
<element name="IndividualName" type="string"/>
<element name="SpouseName" type="string"/>
<element name="BirthDate" type="dateTime"/>
</sequence>
</complexType>
Now the Web Service generator runs, but just doesn't generate any PersonInfoType class at all. For a stub implementation it genertes the following:
public class PersonInfoImpl {
public SOAPElement processPersonInfo(String entityCode) {
return null;
Now I'm stuck with the container just expecting from me a Soap Object and I have to build all the pieces myself with no java mappings to my xsd at all. Not very useful.
Is there another xml structure I can use to represent data rows that is better supported by the wizard?
Thanks,
Steve

Java code samples for java mappings

Dear all,
Can you please send me a sample scenario in which you used the java mapping.
How do we assign the source structure,the target structure.
How do we map source->target
Do we give the source and target interface names in execute method)?
if so where do we map the same.
we have one to one mapping in graphical,message mappings which i worked with.
is there any tool for making the same thing in java?
Kindly send me the documents if any on java mapping to [email protected]
Please clarify.....

Calling an EJB from Java Mappings in PI 7.1

In my operation mapping, I am using a Java class which in turn invokes an EJB using JNDI lookup.
When I execute the code, the class is successfully finding the EJB using JNDI, but invoking it I am getting a java.lang.NoClassDefFoundError.
If, I add the class it cannot find to the jar containing the Java mapping class, I get a java.lang.ClassCastException.
Has anyone been able to call a custom EJB from with a Java Mapping class?
Any help appreciated.
Thanks.

ABAP mapping
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.
refer step by step guides for ABAP Mapping

ABAP Mapping Vs Java Mapping.
Re: Message Mapping of type ABAP Class not being shown

XSLT Mapping
XSLT stands for EXtensible Stylesheet Language Transformations. It is an XML based language for transforming XML documents into any other formats suitable for browser to display, on the basis of set of well-defined rules.

Steps required for developing XSLT Mapping
u2022 Create a source data type and a target data type
u2022 Create Message types for the source and target data types.
u2022 Create Message Interfaces includes Inbound Message interface and Outbound Message interface.
u2022 XSLT Mapping does not require creation of Message mapping, so donu2019t create any Message mapping.
u2022 Create an .XSL file which converts source data type into target data type.
u2022 Zip that .xsl file and import it into Integration Repository under Imported Archives.
u2022 In Interface Mapping choose mapping program as XSL and specify this zip program. (Through search help you will get XSL Mapping programs that you imported under Imported Archives, select your corresponding XSL Program)
u2022 Test this mapping program by navigating to Test tab.
By having look at above steps you can easily find out that this mapping is no where different from other mapping programs, here the challenging lies in creating an XSLT file. If you spend couple of minutes in studying XPATH tutorial you would be in ideal position to create an XSL Transformation (.xsl extension).
If you still find difficulties in generating XSL Transformation, then you can make use of a tool u201CAltova MapForceu201D which will create XSL file for you.
Steps for creating XSL file using this tool:
1. Open the Alto MapForce, import the source .xml and .xsd file in it
2. Similarly import the target .xml and .xsd in MapForce.
3. These two data files should match with source and target data types in Integration Repository.
4. Complete the graphical mapping using extensive list of XSLT functions available there.
5. Save the mapping file.
6. Click the XSLT tab. You will have the entire xslt logic there.
7. Copy that content and save it as .xsl file.
8. Zip above .xsl file and import the same into IR under Imported Archives.
Hope this clears your doubts

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

import com.sap.aii.mapping.api.*;
import java.io.InputStream;

PI 7.11 - Where can I get the NEW java API's

Hi,
We use PI 7.0 in productive environment, but we plan a release update to PI 7.11. We have several Java Mappings for PI 7.0 with Java 1.4. So we have to upgrade this also to Java 1.5.
We are using following SAP Java libs:
- aii_map_api.jar
- aii_mt_rt.jar
- guidgenerator.jar
- sapxmltoolkit.jar
Where can we get the equivalent libraries of the PI 7.11 system. Are there new API's? Is there a documentation where to get this?
Thx in advance

How to set adapter specific message attributes on Pi 7.1 inside a Java map.

Hello,
how can I set adapter specific message attributes in a Java mapping on PI 7.1.? The TransformationInput grants access to the DynamicConfiguration but the TransformationOutput doesn't. I have found threads refering to the old way of implementing Java mappings (e.g. Get dynamic filename in a Java Mapping (NOT UDF)). But there doesn't seem to be one refering to the actual PI.
Kind regards,
Heiko

Using DynamicConfiguration from the TransformationInput works.

Issue with java mapping in a multi-mapping scenario

Hi
    We have a 1:n multiple mapping scenario in XI and the source is R3 proxy and target side is files. So, creating multiple file from a single message from R3 .
R3 --> XI --> Multiple files
Structure of the output of the multi-mapping is
- <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
- <ns0:Message1>
<Transaction>
</Transaction>
<Transaction>
</Transaction></ns0:Message1>
</ns0:Messages>
wherein each Transaction node represents a file.
Now, we need to introduce a constant /string like
<!DOCTYPE Transaction PUBLIC \"-//XXXXXX//DTD BatchReceiptAuthorization//EN\" \"http://dtd.XXXXXXX.com/dtds/ReceiptAuthorization.dtd\">
on each of the files at the very beginning - i.e within each transaction node , in the above structure, we need the above DTD string to be written. To do this, we added a java mapping as the second mapping after the message mapping that creates this string. Is this the right approach and would it produce what we are expecting ?
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.util.Map;
import com.sap.aii.mapping.api.StreamTransformation;

               String NameSpacePrefix = "<!DOCTYPE Transaction PUBLIC \"-//innotrac//DTD BatchReceiptAuthorization//EN\" \"http://dtd.innotrac.com/dtds/ReceiptAuthorization.dtd\">";
               String sLine = null;
               StringBuffer XmlMsg= new StringBuffer();
               String Result,PayloadBody;
               int indexOfFirst;
               while ((sLine = reader.readLine()) != null) {
                    XmlMsg.append(sLine);
               String StartingTag = XmlMsg.toString();
               indexOfFirst = StartingTag.indexOf("<MerchantID>") ;
               PayloadBody=new String(XmlMsg.substring(indexOfFirst));
               Result=NameSpacePrefix.concat(PayloadBody);
               output.write(Result.getBytes());
          /*     Thread.sleep(200000); */
          }catch(Exception e){
               myTrace.addWarning("Exception raised in the JavaMapping:modifyNamespace.java""\n The Exception Message: " e.getMessage());
               throw new RuntimeException(e.getMessage()) ;
        }     public void setParameter(Map param) {
          myTrace = (AbstractTrace) param
                    .get(StreamTransformationConstants.MAPPING_TRACE);

Hi XI Gurus
                   In my scenario, I sent the inputstream that is being passed to the Java execute method - to trace and I see that the whole of the xml file - as shown below - which is the output of message mapping ( from the first mapping step ) in sent to the execute method of the java mapping a single call
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<Transaction> </Transaction>
<Transaction> </Transaction>
</ns0:Message1>
<ns0:Messages>
So, I modified Java mapping program to look for multiple occurences of <Transaction> tag and prefix them with my constant DTD Literal - which is the primary reason , why I had to use Java mappings after the message mapping.
Now, I get an error is XI- SXMB_MONI
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="">
<SAP:Category>XIServer</SAP:Category>

<SAP:P1>unexpected symbol; expected '<', '</', entity refe</SAP:P1>
<SAP:P2>rence, character data, CDATA section, processing i</SAP:P2>
<SAP:P3>0</SAP:P3>
<SAP:P4>113</SAP:P4>
<SAP:AdditionalText />
<SAP:ApplicationFaultMessage namespace="" />
<SAP:Stack>The exception occurred (program: CL_XMS_MAIN===================CP, include CL_XMS_MAIN===================CM00A, line: 609)</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Should I create multiple outputs - as many as the numberof target split files ( of type outputstream ) from the execute method in the java program ?

Java mappings ?
