Hi

Find this link

https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/6153

Download

aii_map_api.jar (For Java Mapping)

In XI Server : \usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\apps\sap.com\com.sap.xi.services

and get aii_map_api.jar

You can test u r java mapping from u r desktop by providing the test file

see code as below:

public static void main(String[] args)
	{
		FileInputStream in = null;
		FileOutputStream out = null;
		ValidateSchema test = new ValidateSchema();
		try {
			*test.execute(in,out);*
		} catch (StreamTransformationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		try
		{
		 in = new FileInputStream ("*C:/Documents and Settings/9000031/Documents/SAP/workspace/ValidateXml.xml*");
		 out = new FileOutputStream ("*C:/Documents and Settings/9000031/Documents/SAP/workspace/ValidateOutput.xml*");
		}
		catch (IOException io)
		{
			io.printStackTrace();
		
		
	}
	}

Hi Sankara,

U can either export the file as a jar or as a zip file.

if u r using NWDS,click on the class select export -jar and save it on ur local folder.

In imported archive option in mapping objects,import the jar and use it in interface mapping.

But remember it is always better to use a main method in ur java program to test it in the editor it self as a standalone application, to avoid the reimporting it again and again.

public static void main(String[] args)

{

try {

InputStream in =new FileInputStream(new File("C:/ ur file path"));

OutputStream out =new FileOutputStream(new File("C:/ file path"));

mappingClass myMapping = new mappingClass();

myMapping.execute(in, out);

}

catch (Exception e)

{

System.out.println(e.toString());

}

}

Should help u out

hi

download file "SAPXITOOL13P_3-20000274.zip" from the sap pages.

It contains several .sda files which contain all the java-packages (like "aii_map_api.jar") you need for XI-Java mapping.

check the below blog

Hi,

If u haver u r XI Server Access get into following path to get the jar file

\usr\sap\<SID>\DVEBMGS00\j2ee\cluster\server0\apps\sap.com\com.sap.xi.services

Hope u r using NWDS or Eclipse to write JAVA Coding.

So before coding add Jar file to the Java project which u have created.

hope this serves u carrying on with the rest

Hi,

Well once u have tested u r Java mapping,

just ZIP it.

Use in Interface Mapping "There u can select the type of Mapping u r gonna use"

Select from Drop down : JAVA : And use u r "Java.Zip" files.

Before doing so u have to import that zip File under "Imported Archive"

under that SWCV.
