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.

Ananth

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???

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?

How to run an application i created in java without using eclipse

Im familiar with running an application i create thru command prompt or eclipse, how do i create a file to run on any computer with java so i can double click the file and my application runs. C# automatically does this, do i need to do an extra step to the jar file?

Hi,
You need to make an executable JAR file. There are a few ways you can do this but since you are using Eclipse you can follow this tutorial.
[http://www.fsl.cs.sunysb.edu/~dquigley/cse219/index.php?it=eclipse&tt=jar&pf=y]
The most important part is the manifest file, if you have dependencies on other JAR files they will need to be specified along with the
main method to call to start you program. You can do this via the Eclipse Wizard.
It will be in your interests to read this tutorial also

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 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 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.
Regards

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.

Functions used in Java mapping

hi
If anybody has worked on Java mapping, Can anybody tell me the common functions that are used in Java mapping along with some examples
Also how java mapping is more useful as compared to XSLT and ABAP mapping, when to use java mapping and some demo example on java mapping if available
Thanks & regards,

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.

Message and Java Mapping

Hello -
I have a java mapping and a message mapping implemented in one interface.
Java mapping basically adds a header and does nothing else.
Message mapping has all the mapping. Its not complex but straight.
I have the Message mapping first and then the Java mapping in the Interface Mapping.
what happens is i could see the headers written through Java mapping in my output xml file which is good but i cannot view the message mapping output in the file.
Any ideas.
Thanks,
Tirumal

Hi
I am generating the headers in the java mapping using this:
public void startDocument ()
throws SAXException {
write("<?xml version='1.0' encoding='UTF-8'?>");
write("<!DOCTYPE cXML SYSTEM 'http://xml.cxml.org/schemas/cXML/1.1.008/cXML.dtd'>");
Maintain Order at Runtime is checked in the Interface Determination.
Ok, in the interface Mapping Editor i get 2 messages:
1.
11:09:48 Start of test
Call method execute of the application Java mapping com.sap.xi.tf._Orders_MM_
Java mapping com/sap/xi/tf/_Orders_MM_ completed. (execute() of com.sap.xi.tf._Orders_MM_

2. XML not well formed
None of the above messages seem to be of Message Mapping don't know why its not getting written in the output.

How to code in java to use the web services of CRM

Hi,
I am new to CRM on demand web services. I want to develope a java J2EE application to insert some lead data into CRM on demand. But i have no idea of how the wsdl provided by CRM can be converted to a java class so that i can use the API's provided by them in my program. I am using Eclipse Galileo IDE for my java application development. Can any one tell me the way to reference the wsdl in my program or any other way to build my application.
Please help me out.
Thanx in advance.

May be it's the 'stub' you should be looking for.
Any Account related queries/creations - AccountStub
--> Query : Populate AccountQuery, populate AccountQueryPage_Input, call accountStub.accountQueryPage(input);
--> Creation: Populate AccountData, populate AccountInsert_Input, call accountStub.accountInsert(input)
It's the same procedure for other objects like Contact, Lead, Opportunity.
I worked on other web-services using Axis2, and 'Stub' has been the one which we use to connect to the web-service.

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.

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

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.
For further info on each of the mapping, refer to these links,

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