Adding Carriage Return or Line Feed IN xml FILE using JAVA Mapping through Command Prompt:

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.

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.

Give the name and click on create.

Click on import archive and then select “AddCRorLF.jar” then open.

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

In Test tab.
