Hi Urtzi,
Use this code as java mapping, I tested this and it is working.
import java.io.*;
import java.util.Map;
import java.util.HashMap;
import java.util.*;
import java.util.zip.*;
import javax.swing.ImageIcon;
import com.sap.aii.mapping.api.AbstractTrace;
import com.sap.aii.mapping.api.*;
import com.sap.aii.mapping.api.AbstractTransformation;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;
import com.sap.aii.mapping.api.StreamTransformationException;
import java.io.FileOutputStream;
import com.itextpdf.text.Image;
import com.itextpdf.text.pdf.PdfContentByte;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.PdfStamper;
public class WaterMarkJM extends AbstractTransformation
{
static final int BUFFER = 1024*1000;
private Map param;
public WaterMarkJM(){ }
public void setParameter (Map map)
{
param = map;
if (param == null)
{
param = new HashMap();
}
}
public static void main(String args[])
{
try
{
FileInputStream fin = new FileInputStream(args[0]);
FileOutputStream fout = new FileOutputStream(args[1]);
WaterMarkJM mapping = new WaterMarkJM();
mapping.execute(fin, fout);
}
catch (Exception e)
{
e.printStackTrace();
}
}
public void transform(TransformationInput arg0, TransformationOutput arg1) throws StreamTransformationException
{
this.execute( (InputStream) arg0.getInputPayload().getInputStream(), (OutputStream) arg1.getOutputPayload().getOutputStream());
}
public void execute(InputStream inputstream, OutputStream outputstream)
{
try {
PdfReader Read_PDF_To_Watermark = new PdfReader(inputstream);
int number_of_pages = Read_PDF_To_Watermark.getNumberOfPages();
PdfStamper stamp = new PdfStamper(Read_PDF_To_Watermark, outputstream);
int i = 0;
InputStream in = getClass().getResourceAsStream("<watermark.jpg>"); //NOTE: load your WATERMARK image as part of archive
int len = 0;
byte[] buffer = new byte[BUFFER];
ByteArrayOutputStream baos = new ByteArrayOutputStream();
while ((len = in.read(buffer)) > 0)
{
baos.write(buffer, 0, len);
}
Image watermark_image = Image.getInstance(baos.toByteArray());
watermark_image.setAbsolutePosition(200, 400);
PdfContentByte add_watermark;
while (i < number_of_pages) {
i++;
add_watermark = stamp.getUnderContent(i);
add_watermark.addImage(watermark_image);
}
stamp.close();
}
catch (Exception i1) {
i1.printStackTrace();
}
}
}
As I mentioned earlier, download the itextPDF jar files zip from: http://sourceforge.net/projects/itext/files/iText/iText5.3.0/
extract the zip file and use itextpdf-5.3.0.jar & itext-xtra-5.3.0.jar in your java code classpath for compiling. You need to import these jar file contents along with above WaterMarkJM java class file and your water mark image (zipped file) as an imported archive in PI.
The folder structure for your class file, image file and Itext PDF jar files should look like as below, and these contents need to be zipped and loaded into PI as an imported archive
Now you can download the jar file and directly use it in your interface mapping: https://www.box.com/s/5b56f8ca3955c747c900
Also note that your imported archive should look like this when imported into PI

Hi Praveen,
Thank you very much for your library, now I can do the call.
My doubt is, how have you defined de Message Types? I mean, how is the mapping returning the doc with watermark?
I'm getting an error because the payload has not the correct structure. In Moni the payload:
Thanks a lot!
Regards.
Urtzi.
Yes, the incoming file is a PDF, in moni I can see it in binary because I'm sending through RFC from SAP:
Should I use File Adapter instead?
Thanks!
Regards.
Urtzi.
Praveen,
How do you export im Developer Studio with no Path in class¿?
If I modify your files, I get:
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Thanks!
Urtzi.
