Regarding Java mapping Interface

Hello,
while implementing the java mapping, we need to develop the interface called
com.sap.aii.mapping.api.streamTransformation
So here what is " aii "
how can we develop this interface.
Thank you

Hi Ravi,
com.sap.aii.mapping.api.StreamTransformation is a class contained in the archive aii_map_api.jar so in your java project you need aii_map_api.jar to be able to use class StreamTransformation.
There is no specific meaning for "aii"
For more details about StreamTransformation, you have this:
http://help.sap.com/saphelp_nw2004s/helpdata/en/bd/c91241c738f423e10000000a155106/frameset.htm
The package com.sap.aii.mapping.api.StreamTransformation can be obtained from SAP service Market place.
Thanks
Swarup

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 dont think so when I upload only class file, it says class not found.
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.

Regarding java mapping failure

Hai all
Iam Ajay , here i would like to create XML Tree using DOM Parser. In the java Program i need to import
"com.sap.aii.mapping.*" library. Unfortunately i don't have that. could you suggest me where do i import the jar file which includes the above java library .
Thank you

HI,
The jar files required for java mapping is aii_map_api.jar
You can find this in your your XI server in the following path:
j2ee\cluster\server0\apps\sap.com\com.sap.xi.services

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

Configuration in Java Mapping.

Hi Folks, Here I am in real Need of Some inputs regarding JAVA Mapping. Actually I am working on the Change of a scenario. I just Added some fields to the interface. I added these fields on the Sender structure and the receiver structure.
        I did mapping also for the added fields. Till XI part its working fine. The problem is When I see the Interface mapping they are using the Java Class Mapping as well with the message mapping.
        I am very new to JAVA. I dont know even A..B..C..D of JAVA. That is the reason I am waiting for some to help from our Community.
        Here are some inputs regarding the JAVA mapping. I did some research and find out that they are using the JAVA Mapping for XML Validation. So I came to know that we dont need to change the JAVA files. Java file just reads the Incoming structure and writes to the receiver. Inside the JAVA mapping it is using the XSD file to capture the incoming structure.
        Here is the problem, when I double clik on the java mapping, it is heading to the Imported archives in which we are having .java, .class, .XSD files already imported with some path information. when I just check the code by double clicking the XSD structure it is showing the old XSD. it is not updated with the added fields. So when ever I am testing the Interface its throughing an exception.
        Can any body please help me out in this matter.
         As i am not going to change the JAVA files, Do I need to install the J2SDK in my local Machine.
        What ever the path is showing in the imported archives, will that be in the XI server or again in our local machine. Do we need to create the folders to save any files on our local machines.
        I am in need to change the XSD file in the path. where I need to change the XSD.
        can any body please gimme the clear process regarding java part which I need to follow to complete my development. even though i completed 80% of my development I am struggling with this config from past 4 days. Please help me out. Looking for the positive responses.
     Thanks,
Ramana Avula.

Hi do one thing
Export the whole imported archive for e.g let the name be ABC.
When you click on ABC you find .java .class & XSD file.
export the archive with a .jar extension
for e.g ABC.jar
Now open this jar file with winzip.
you will see the three files i.e. .class .java & XSD
Now using winzip just replace the old XSD with new
The name should be same.
Take care if the XSD file is not present inside any folder
if so then replace it inside that directory only and not outside any folder
for e.g. /com/company/ folder have your .java & class file
but /com/company/xsd/abc.xsd is your xsd file
so replace it in appropriate folder only
And then reimport it back in the same archive

Re-use message mapping from within java mapping?

Hi there,
I have a question regarding java mapping. What I would like to do is to re-use an existing message mapping from within java mapping.
Technicaly, message mapping is perfomed by com.sap.aii.mappingtool.tf3.AMappingProgram.execute, right? I would like to call that mapping program for a specifc message mapping from within my java mapping.
Pseudo java code would look like this:
public void execute(InputStream in, OutputStream out)
throws StreamTransformationException {
com.sap.aii.mappingtool.tf3.AMappingProgram.execute(in,out,'SomeMessageMapping');
SomeMessageMapping is a message mapping that is defined in the integration repository.
Is it possible? If so, could you provide me with some details?
Thank you and best regards,
Wolfgang

Hi Wolfgang,
very interesting idea?
I would activa a dummy message mapping. than I would have a look in the file directory of the java-stack and try to find out the name of the *.class or *.jar file.
On the other hand you could generate a tpz-transport-file an unpack this file, to explore the name of the *.class or *.jar
Unfortunately I do not have access to the file system. So I can't explore the name.

please solve this issue.

Uday,
May be you have uploaded class file into external definitions.
You need to Zip the class file into .jar and then upload into external definitions of integration repository

Without BPM:Call RFC using JCO in interface mapping using java mapping

Hi all
I have a very small scenario where REQUEST from the customer comes via Web Service all i have to do is to read the request using SOAP adapter and call an interface mapping(lets say the name is IM_TEST) inside which there is a JAVA MAPPING program written which will call an RFC in CRM using JCO.
Now this was really simple and i cud test the Interface mapping successfully, but the problem is when loading the scenario in integration directory i have certain things to do
1. to set the SENDER AGREEMENT which i did correctly
2. set the RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT now here i am stuck because there is no receiver in my case as the RFC is called inside the mapping only.
can i call one more message mapping in IM_TEST which will write file onto the XI directory and then in RECEIVER DETERMINATION, INTERFACE DETERMINATION AND RECEIVER AGREEMENT i can mention the reciever as FTP.
I tried it but i gives the following error
Runtime exception occurred during execution of application mapping program com/sap/xi/tf/_MM_TEST_WRITE_FILE: com.sap.aii.utilxi.misc.api.BaseRuntimeException; Parsing an empty source. Root element expected!
Please help me how to complete the scenario so that customer can run it end to end.

Stefen
What do i do then...actually this is the project requirement. They want a very fast response from PI and thats why they wnt us to omit BPM and the Graphical mapping from the scenario.
I am able to test the interface mapping which calls the the Java mapping inside which there is an RFC call, but i cannot implement it end - to - end as there is no receiver business system in this case. The only business system i have is the SOAP sender.
I am really troubled now, please help me with a solution.
Is there any other possible way through which the process can become very fast whic hcan meet their requirement.

Joe,
most likely your XSLT is outputting a not well-formed XML message.
Remove message mapping from the mapping list and execute it again, to check output.
Also, for mapping debugging in java enhanced function inside XSLT mappings, use the following:
1st, you need to pass the "inputparam" parameter from the XSLT runtime to the Java function (it needs to be one of the input parameters for the executed java function).
In the Java code itself, implement the following code:
AbstractTrace trace = (AbstractTrace) param.get(StreamTransformationConstants.MAPPING_TRACE);
trace.addInfo("Log your message here!");
where param is the input parameter refering to the inputparam from XSLT.
The AbstractTrace and StreamTransformationConstants classes can be found in the aii_map_api.jar file (used in Java mappings).
Regards,
Henrique.

Call another Message Interface from Java Mapping

Hi Gurus!!
I have designed a Java Mapping that does a Socket Connection. Before send the response of the Java Mapping, I have to send information to our SAP System.
I have see in a blog that I can call a RFC from the Java Mapping, but my doubt is, can I call another Message Interface designed on XI?
Thanks and regards,
Manuel Míguez.

That's tricky, since the proper way of doing it would be through BPM.
Anyway, if you expose your XI interface as a WebService (Soap sender cc) you could access it through Mapping Lookup (lookup works for RFC, DB and Soap lookups). Check https://help.sap.com/javadocs/NW04S/current/pi/index.html
But be aware that Mapping Lookup API is not intended for inserts/updates (since it doesn't contain any transacational handling), just mere lookups (selects in tables), so I'm not sure it is the best approach for your case.
Regards,
Henrique.

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.

Anamika

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

Accessing a File in a Java Mapping

Hi,
I am accessing one Random Access File through Java Mapping Program. This is working fine in Eclipse.
But when I imported that jar file to IR, it is throwing FileNotFound Exception while trying to test through Interface Mapping.
Actually it is not showing any error message but by research I understood that. Can any one please help me in this regard?
One more thing, I used the same scenario for other interface. It is working fine.
Please help me to chase this mistery.
Thanks,
Yogi.

Hi,
I think I am giving relative path only not direct path. I am just mentioning the path from my proj name. I am not specifying any local directories. For your Information, I am mentioning the path like below:
"ProjectName/SomeName/File_Name.txt"
Thanks,
Yogi.

Special Characters in a Java Mapping

Hello everybody,
in our XI we have an Interface Mapping that uses a Java Mapping, this Mapping is doing a XSD-Validation of a XML-File.
In one XML-File there is more than one special Character (ó, O², ü..). The XI-Parser hat no problems with these characters except one, eventhough this character (ó) exists more than once in the document, the parser doesn't recognize it in only one position (While Parsing the "ó" turns to a "��").
I tested the Mapping in Eclipse and it works correctly. The question is, why the special character could not be interpreted in only one position in the document.
I guess it is a bug in the XI-Parser.
I will be thankful for your help.
Best regards
Adnane

This ó has the same Hex-code as all the others and it is in the same environment.
I definned in the source XML in the repository test the code Page in the XML-header as follows :
<?xml version="1.0" encoding="UTF-8"?> and that works. But when I test the Process at the runtime the problem above occurs.
I think that the interface Mapping is getting a source XML without a header, which defines the encoding as UTF-8, because when i test the Mapping in the repository with the XML-file without the Header information, the problem with the ó occurs.
My question is, where can i define the Encoding of the source-XML of this Interface Mapping?
regards
