1.- You should have any one of the Development Tool like SAP Netweaver Developer Studio, NetBeans, Eclipse

2.- Import aii_map_api.jar library.

3.- Write the Source code for the mapping program. (We need to know DOM or SAX parsing proccesing)

4.- Generate .jar file with the compiled class.

5.- Import Jar File in SAP PI.

6.- Use the program mapping in Interface Mapping.

In UDF

You can use Trace to check the value

AbstractTrace trace= container.getTrace();

trace.addWarning("Trace will be now seen using trace object");

More on this link,

Also, in SXMB_ADM , you can set the TRACE_LEVEl parameters to 1 , 2 or 3. 3 will give you all info all pipeline steps. But, the problem will happen in the fact that memory gets filled up when trace is 3 and so make it 3 only for debugging!

Hi,

For first question refer to blog

2. The System.out.print statement will be printed on the server command prompt where the xi server is running. You as developoer cannot see that. Although for debugging purpose you can use AbstractTrace trace.addInfo() to log and see the messages.

Thanks

Venkat,

Ok..too many responses, nobody is reading your question..

IN your UDF........one of the params passed in is Container.........

add this

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

AbstractTrace at;

at = container.getTrace();

now you can write you sysout like this.......

//System.out.println("something");

at.addInfo("something);

or at.addWarning("Something");

Then run your mapping test...you will see this in the output log...........
