Example

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

package com.tutorialspoint;

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();

         // set the handler
         attachPart.setDataHandler(handler);

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

         // set content-Type a new value
         attachPart.setMimeHeader("Content-type", "New Value");

         // print the mime header
         System.out.println("" + attachPart.getMimeHeader("Content-type")[0]);

      } catch (Exception ex) {
