PI 7.1 Email Attachment binary file

Question

Hi,
I am trying to attach a binary (encrypted) file to a regular mapped email (receiver adapter) before sending it.
It is similiar to attach pdf-files at the end of a mapping process.
Is there no way to attach binary files other than writing an adapter module?
Is there no generic "Attach File" module in PI 7.11?
I tried ASMA with XSLT, but the problem is, that the file is binary and the sender adapter would not read it without xml-format.
Any good idea?
thanks

Hi Holger,
Just a suggestion:
1. Read the binary file using file adapter (in binary mode)
2. use a mail package and put the read content into the Content node of it. You can use this java mapping for it
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import com.sap.aii.mapping.api.AbstractTransformation;
import  com.sap.aii.mapping.api.DynamicConfiguration;
import com.sap.aii.mapping.api.DynamicConfigurationKey;
import com.sap.aii.mapping.api.StreamTransformationException;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;
import com.sap.aii.mapping.api.InputHeader;
public class JavaMapping extends AbstractTransformation {
     public void transform(TransformationInput arg0, TransformationOutput arg1) throws StreamTransformationException {
     getTrace().addInfo("JAVA Mapping Called");
     //Input payload is obtained by using arg0.getInputPayload().getInputStream()
     String inData = convertStreamToString(arg0.getInputPayload().getInputStream());
     String outData = inData
     try
     //8. The JAVA mapping output payload is returned using the TransformationOutput class
     // arg1.getOutputPayload().getOutputStream()
          arg1.getOutputPayload().getOutputStream().write(outData.getBytes("UTF-8"));
     catch(Exception exception1) { }
     public String convertStreamToString(InputStream in){
     StringBuffer sb = new StringBuffer();
     try
     InputStreamReader isr = new InputStreamReader(in);
     Reader reader =
     new BufferedReader(isr);
     int ch;
     while((ch = in.read()) > -1) {
          sb.append((char)ch);}
          reader.close();
     catch(Exception exception) { }
     return sb.toString();
Then provide the filename dynamically into the ContentType of the mail package.
I guess this should work.
