For java mapping

1.Develop Java code with ur IDE

2.create a .jar or .zip file

3.Create new imported archive and import the jar file

The java class must implement com.sap.aii.mapping.api.StreamTransformation

and must contain 2 methods

1. public void execute(java.io.InputStream in,

java.io.OutputStream out)

to perform the mappings.

2. public void setParameter(java.util.Map param)

to access to runtime constants possible

(for example: INTERFACE, SENDER_NAME)

and requires libraries contained in aii_map_api.jar

Hi,

You can use Java Mapping for any scenario you want.

You can use DOM, but try to understand SAX too, as SAX takes up much less space.

If you want to make a completely new structure, use DOM, else use SAX. SAX works on the principle of event-handling.

DOM, on the other hand, needs to load the <i>entire</i> XML structure into memory. Hence, it is resource-intensive.

configure a simple file-file scenario but here u dont go 4 graphical mapping rather u create a java mapping and import it as a JAR file and make use of the class.

prabhu u r true...i wanted a sample code that can do java mapping by parsing source XML and converting it to Target XML file

Look into the blogs I have pointd out. They have source code and the explanation as well.
