AttachmentPart setBase64Content() Method

Description

The Javax.xml.soap.AttachmentPart.setBase64Content(InputStream content, String contentType) method sets the content of this attachment part from the Base64 source InputStream and sets the value of the Content-Type header to the value contained in contentType, This method would first decode the base64 input and write the resulting raw bytes to the attachment. A subsequent call to getSize() may not be an exact measure of the content size.

Declaration

Following is the declaration for javax.xml.soap.AttachmentPart.setBase64Content() method

public abstract void setBase64Content(InputStream content, String contentType)

Parameters

• content − the base64 encoded data to add to the attachment part

• contentType − the value to set into the Content-Type header

Return Value

This method does not return a value.

Exception

• SOAPException − if an there is an error in setting the content

• NullPointerException − if content is null

Example

The following example shows the usage of javax.xml.soap.AttachmentPart.setBase64Content() 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 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";

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

         // encode attachment and add it as AttachmentPart      
         byte[] encoded = Base64.encode(attachment.getBytes());
         ByteInputStream bis = 
            new ByteInputStream(encoded, 0, encoded.length);
         attachPart.setBase64Content(bis, "plain/text");

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

         // get the inputstream for attachPart
         InputStream is = attachPart.getBase64Content();

         // print the content
         for (int i = 0; i < is.available(); i++) {
            System.out.print("" + (char) is.read());
         }

      } catch (Exception ex) {
         ex.printStackTrace();
      }
   }
}

If we compile the code and execute it, this will produce the following result −
