Problem Statements:

Adding Carriage Return or Line Feed after tag.

This problem can be solved by using XSLT and Java Mapping I am here define only  through .

JAVA Mapping:

Here I take example of customer balance interface which Proxy to file scenario. And I am not using any java base tool like Eclipse for java or Netweaver Developer Studio. I am using simple java commands using command prompt to execute java file and creating jar file.This blog also explain basics of java mapping.

1.  For Java Mapping first we need “aii_map_api.jar” jar files that can find from various ways

You can check below Wiki for that:

http://wiki.sdn.sap.com/wiki/display/XI/Where+to+get+the+libraries+for+XI+development

I used the last option define there

Copy files from the local cache directory:

C:\Users\BatraG(logon- user)\AppData\LocalLow\Sun\Java\Deployment\cache\javaws\http\DAM001(PISERVER) \P51000\DMrep\DMrepository

File name: RMaii_map_api.jar

You can rename that file to: aii_map_api.jar

  •   I create a file named: AddCRorLF.java with following code.

A simple code is written in java for add Carriage Return or Line Feed after tags.

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.InputStream;

import java.io.OutputStream;

import java.util.Map;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.transform.Transformer;

import javax.xml.transform.TransformerFactory;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import javax.xml.transform.OutputKeys;

import org.w3c.dom.Document;

import org.w3c.dom.Node;

import org.w3c.dom.NodeList;

import com.sap.aii.mapping.api.StreamTransformation;

import com.sap.aii.mapping.api.StreamTransformationException;

public class AddCRorLF implements StreamTransformation{

            public void execute(InputStream in, OutputStream out)

                                    throws StreamTransformationException {

                         try

          {

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

factory.setNamespaceAware(true);

DocumentBuilder builder = factory.newDocumentBuilder();

Document doc = builder.parse(in);

TransformerFactory tFactory = TransformerFactory.newInstance();

Transformer t = tFactory.newTransformer();

t.setOutputProperty(OutputKeys.INDENT, “yes”);

t.transform(new DOMSource(doc), new StreamResult(out));

          }

          catch(Exception e)

          {

e.printStackTrace();

               throw new StreamTransformationException(“Error During Mapping”, e);

          }

            }

            public void setParameter(Map arg0) {

            }

}

  • A time to compile the file.

Put both files in one folder as below:

Commands:

Cd\

Cd d:\gagan

Javac –classpath aii_map_api.jar AddCRorLF.java

After that class file will created.

Then use following command for creating jar file:

Jar cvf  AddCRorLF.jar AddCRorLF.class AddCRorLF.java

Then you can see following file in the folder:

  • Go to Repository part and I have created following Message mapping for Customer Balance:

Right click on imported archive and create new.

Following files are uploaded.

Then Save And Activate.

Then Go to Interface Mapping that I have all ready created.

Earlier it is showing like that at test tab all result is coming in one line:

Now add our java mapping after message mapping.

Select our Class

You can see following java mapping added after message mapping
