Example

The following example shows the usage of javax.xml.soap.AttachmentPart.setRawContent() method.

package com.tutorialspoint;

import com.sun.xml.internal.messaging.saaj.util.Base64;
import com.sun.xml.internal.messaging.saaj.util.ByteInputStream;
import java.io.InputStream;
import java.util.Iterator;
import javax.activation.DataHandler;
import javax.xml.soap.*;

public class AttachmentPartDemo {

   public static void main(String[] args) {
      try {

         // create a new SOAPMessage
         SOAPMessage message = MessageFactory.newInstance().createMessage();

         // create a string as a new attachment 
         String attachment = "This is an attachment";

         // get the data handler and assign the attachment
         DataHandler handler = new DataHandler(attachment, "HandlerHeader");

         // create the attachment part
         AttachmentPart attachPart = message.createAttachmentPart();

         // add raw content
         byte[] encoded = Base64.encode(attachment.getBytes());
         ByteInputStream bis =
            new ByteInputStream(encoded, 0, encoded.length);
         attachPart.setRawContent(bis, "plain/text");

         // add the attachment part in the message
         message.addAttachmentPart(attachPart);

         // read the raw content
         InputStream content = attachPart.getRawContent();
         for (int i = 0; i < content.available(); i++) {
            System.out.print("" + (char) content.read());
         }
      } catch (Exception ex) {
         ex.printStackTrace();
      }
   }
}
