XI java mapping using SAX

Hi,
im using java mapping for complex IDOC structure. If I run program localy, it works great, but when XI runs mapping, I have problems with xml file, some elements are not there ?! I don't know why it happens.....i said that i'm using complex logic, and therefore I'm using complex IF statments to produce segment in IDOC. I have noticed that there is a problem, because when I switch off IF, everything is fine???? any idea??
thx mario

Hi,
Do you have nested 'if' statements? Is it possible you could be experiencing a "dangling else" problem?

JAVA mapping using SAX parser adds extra tags

Hi,
We are using java mapping using a SAX parser.It works well in standalone application ie it parses correctly and gets our desired xml structure and the xml is well formed too but when we import it in XI as a jar file it does not throw any errors but adds extra start tags, as a result the output xml is not well formed.XI is adding extra start tags.
If any one else has faced a similar situation please help.
Regards,
Anirban.

Hi Roberto,
Thank you for the response.
As I said, it doesnt throw any error. It is working perfectly in standalone application. But when we deploy it to XI Server, it is not forming the well formed XML. We too are puzzled by this situation.
Okay, i will explain my scenario here.
The following is my input XML to the java pgm..
<Header>
</Header>
<Body>
</Body>
<SubBody1>
</SubBody1>
<SubBody2>
</SubBody2>
<SubBody3>
</SubBody3>
<SubBody4>
</SubBody4>
<Trail>
</Trail>
The desired output is
<Header>
<Body>
<NameChanged1>
<NameChanged2>
<SubBody3>
<SubBody4>
</SubBody4>
</SubBody3>
</NameChanged2>
</NameChanged1>
<Trail>
</Trail>
Just look at the SubBody2 and SubBody1 node, its tag name has been changed in the output XML. Thats y i have decided to use java mapping instead of message mapping.
I have developed the code for everything, i.e for changing the tag name and for forming the nested xml and it is working fine as a standalone application. But while deploying it to XI, the output is not well formed. I dont know the reason for it. Even I have checked the cardinality of the output Data types, that I have created. Its perfectly okay with all.
Any Ideas???

JAVA Mapping with SAX: Illegal character exception &

Hi everybody,
I use a SAX JAVA Mapping. It throws an error cause the xml that is parsed has a
&
like in
<D_3036>Company & Co. KG</D_3036>
Does anybody know how to solve the problem?
I do not want to replace the
&
Are there special settings/properties for the handler/parser?
Thanks
Regards
Mario

Hi all,
thanks for your comments and suggestions. The error was not cause by the problem I describes.
FYI:
If there is an ampersand in the middle of a string, than the standard method
characters
in the handler is called three times!
This let me asume the ampersand was the error.

Java Mapping using DOM

Hi All,
I need Java mapping help. I will get incomming payload as following
<orders>
<matnr>123</matnr>
<qty>10</qty>
</orders>
i need to change the above payload as follows
<ns0:orders>
<ns0:matnr>123</ns0:matnr>
<ns0:qty>10</ns0:qty>
</ns0:orders>
Please help me how to achieve this using Java mapping.

Hi,
Dom will be quite expensive for this type of requirement since you will have to go to each element and then append the namespace.
I suggest you use SAX parser which is more efficient for such requirement.
The code is given below you can modify it according to your requirement.

Java Mapping Using DOM Parser.

Hi Experts,
I am new to Java mapping and i have followed the link
http://scn.sap.com/thread/3173071 and it is working fine. It is for only one item. I have tried to modify the code and i placed a for loop to go create the Output Node based on the No of Input Nodes and it is giving the error as below. But my requirement is

Java Mapping Using JAXB [Java Arch for XML Binding]

Hi All,
Anyone tried using JAXB [Java Architecture for XML Binding API available with Java WebServices Pack] technique for XML processing in Java Mapping??
I am facing the following problems..
1. I am not able to generate namespace while marshalling target XML [In standalone mode and not tried in XI].
2. What are the jar files we need to import?
I tried importing the following jar files in XI.
jaxb-api.jar,jaxb-impl.jar,jaxb-libs.jar,jax-qname.jar,namespace.jar,relaxngDatatype.jar
and getting some errors while importing these files in XI.
3. It throws error at runtime [Interface Mapping-Test Tab]
like Resource not found:javax/xml/bind/Messages_en.properties,javax/xml/bind/Messages_en_US.properties
4. Even after creating a copy of available file Messages.Properties with name: Messages_en.properties and Messages_en_US.properties.. it is not generating any messages in Target message tab
Thanks in Advance,
Ananth Chinnaraj

Sravya ,
I have searched wide and far for this, but no success.
A lot on JAXB XI and Webdynpro, but nothing on JAXB, XI and mappings.
Could you please post the url here ?
Thanks and kind regards,

Java Mapping - using Eclipse as IDE.

Hello,
We need to write a complex java mapping. We are currently planning to use Eclipse IDE for developing the mapping class. (we dont have the NW studio unfortunaltey). The user defined function option in the IR will not suffice.
My question is - where do we get the com.sap.** libraries from - so that we can import those packages in our mapping code?
Thanks.

Hi,
The necessary Jar files are downloaded & available in your PC when you use Integration Builder tools.
Normally Java webstart caches these files in your local directory.
You can find Java mapping related Jars in the following directory :
C:Documents and Settings%USER%Application DataSunJavaDeploymentjavawscachehttp%HOST%P50000DMrepDMrepository
Goto the directory, search for files like *aii_map_api.jar
It will give you list of Jar files like RMaii_map_api.jar , just rename it as aii_map_api.jar and use it in Eclipse or NWDS.
Note: While searching for Jar files take only Jar files with ~30KB size from the search results.
regards,
Ananth

Help Required in java mapping using XI

Does any body worked on java Mapping in XI
where do u find the com.sap.aii.*;
thank's in advance
swamy

Hi,
To access the mapping API, you must include the Jar file aii_map_api.jar in your class path. The Jar file is located in the following directory:
<SAP_install_dir>/<system_name>/<instance_name>/j2ee/cluster/server<number>/apps/sap.com/com.sap.xi.services/
To include the three J2EE standard libraries in the class path of the NetWeaver Developer Workplace, call the Set Additional Libraries... function in your Eclipse project by calling the context menu and selecting the libraries
com.sap.tc.Logging,
com.sap.mw.jco
sapxmltoolkit.
Hope this solves your problem.

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.

Graphical Mapping Vs XSLT mapping Vs Java Mapping Vs ABAP Mapping

Hi Experts,
I have a question regarding different message mapping options available in XI namely
Graphical Mapping
XSLT mapping
Java Mapping
ABAP Mapping
Q1: Which amoung the above mappings is the best and why?
Q2: On what cases Graphical, XSLT, Java and ABAP Mapping should be used?
Q3: Is it true that graphical and XSLT mappings are converted into Java class internally?
Kindly help!
Thanks
Gopal

Hi,
There is no hard and fast rule for using the mapping techniques.
Graphical Mapping is used for simple mapping cases. When, the logic for your mapping is simple and straight forward and it does not involve mult hiearchical mapping requirement. and context handling.
Java and XSLT mapping are used when graphical mapping cannot help you.
When the choice is between Java And XSLT, XSLT is simpler than java mapping and easier. But, it has its drawbacks. XSLT can lead to a bad perfrormance if the Source XML is huge.
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 exaclty easy to develop either.

Am not sure about XSLT , but , yes graphical mapping is converted into java classes internally and these classes use SAX parsing as well.

Java Mapping, XSLT Mapping, ABAP Mapping

Hi Experts,
Could any one explain what is the main features of the following Mapping. How to pick the mapping?
Java Mapping - When to use and what is the advantage.
ABAP Mapping - When to use and what is the advantage.
XSLT Mapping - When to use and what is the advantage.
Graphical Mapping - When to use and what is the advantage.
cheers,
Sunee

There are 4 types of mapping in XI
1. Graphical Mapping
2. XSLT Mapping
3. JAVA Mapping
4. ABAP Mapping
When to use Message mapping
1 When the logic for your mapping is simple and straight forward, you can use
Advantages of message mapping
1)Easy to use.
2) has GUI drag and drop.
3) used for simple mapping cases
4) it does not involve any complex logic
Disadvantages of message mapping
1)has limitation in terms of complex hierarchy
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.
Disadvantages of Java mapping
1)SAX parser is not easy to develop
2)DOM parser is intensive
3) Java knowledge is required
4) bit complexer
XSLT Mapping - When to use
1)When the required output is other than XML like Text, Html or XHTML (html displayed as XML )
2)When default namespace coming from graphical mapping is not required or is to be changed as per requirements.
3)When data is to be filtered based on certain fields (considering File as source)
4)When data is to be sorted based on certain field (considering File as source)
5)When data is to be grouped based on certain field (considering File as source)
Advantages of using XSLT mapping
1)XSLT program itself defines its own target structure.
2)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.
3)XSLT provides use of number of standard XPath functions that can replaces graphical mapping involving user defined java functions easily.
4)File content conversion at receiver side can be avoided in case of text or html output.
5)Multiple occurrences of node within tree (source XML) can be handled easily.
6)XSLT can be used in combination with graphical mapping.
7)Multi-mapping is also possible using xslt.
8)XSLT can be used with ABAP and JAVA Extensions
Disadvantages of using XSLT mapping
1)Resultant XML payload can not be viewed in SXMB_MONI if not in XML format (for service packs < SP14).
2)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.
3)XSLT mapping requires more memory than mapping classes generated in Java.
4)XSLT program become lengthier as source structure fields grows in numbers.
5)XSLT program sometimes become complex to meet desired functionality.
6)Some XSL functions are dependent on version of browser.
Advantages of Abap Mapping
1) A person comfortable with OOABAP can go for ABAP mapping instead.
Disadvantages of Abap Mapping
1) Abap knowledge is required
2) bit compexer
For further info on each of the mapping, refer to these links,

Different types of Mapping in XI

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.

Hi Anupam,
The Java Mapping code is same in Dev , QAS and Prod. Also the versions of the JAR is same.

New to JAVA mapping

Hi All,
I have been working in PI for sometime now. But i have never done JAVA mapping or writing modules in PI. Now i am in need of working on either of these. I have no idea on the topics mentioned above. I tried searching for docs and links on these and was successful in finding only example scenarios, which was not very clear.
Can anyone give me details on these for a beginner please? I mean how to start with JAVA mapping and basics in it.
Regards,
Lavanya R

Hi Lavanya,
There are multiple blogs for Java Mapping,you can start following those links:
