public abstract Class AttachmentPart

extends Object
Class Inheritance
Imports
java.io.InputStream, java.util.Iterator, javax.activation.DataHandler

A single attachment to a SOAPMessage object. A SOAPMessage object may contain zero, one, or many AttachmentPart objects. Each AttachmentPart object consists of two parts, application-specific content and associated MIME headers. The MIME headers consists of name/value pairs that can be used to identify and describe the content.

An AttachmentPart object must conform to certain standards.

  1. It must conform to MIME [RFC2045] standards
  2. It MUST contain content
  3. The header portion MUST include the following header:
    • Content-Type
      This header identifies the type of data in the content of an AttachmentPart object and MUST conform to [RFC2045]. The following is an example of a Content-Type header:
            Content-Type:  application/xml
            
      The following line of code, in which ap is an AttachmentPart object, sets the header shown in the previous example.
            ap.setMimeHeader("Content-Type", "application/xml");
            

There are no restrictions on the content portion of an AttachmentPart object. The content may be anything from a simple plain text object to a complex XML document or image file.

An AttachmentPart object is created with the method SOAPMessage.createAttachmentPart. After setting its MIME headers, the AttachmentPart object is added to the message that created it with the method SOAPMessage.addAttachmentPart.

The following code fragment, in which m is a SOAPMessage object and contentStringl is a String, creates an instance of AttachmentPart, sets the AttachmentPart object with some content and header information, and adds the AttachmentPart object to the SOAPMessage object.

    AttachmentPart ap1 = m.createAttachmentPart();
    ap1.setContent(contentString1, "text/plain");
    m.addAttachmentPart(ap1);

The following code fragment creates and adds a second AttachmentPart instance to the same message. jpegData is a binary byte buffer representing the jpeg file.

    AttachmentPart ap2 = m.createAttachmentPart();
    byte[] jpegData =  ...;
    ap2.setContent(new ByteArrayInputStream(jpegData), "image/jpeg");
    m.addAttachmentPart(ap2);

The getContent method retrieves the contents and header from an AttachmentPart object. Depending on the DataContentHandler objects present, the returned Object can either be a typed Java object corresponding to the MIME type or an InputStream object that contains the content as bytes.

    String content1 = ap1.getContent();
    java.io.InputStream content2 = ap2.getContent();
The method clearContent removes all the content from an AttachmentPart object but does not affect its header information.
    ap1.clearContent();

1.6

Note that RFC822 headers can contain only US-ASCII characters.

Parameters
name:String

a String giving the name of the header to be added

value:String

a String giving the value of the header to be added

Exceptions
IllegalArgumentException:
if there was a problem with the specified mime header name or value

getBase64Contentback to summary
public abstract InputStream getBase64Content() throws SOAPException

Returns an InputStream which can be used to obtain the content of AttachmentPart as Base64 encoded character data, this method would base64 encode the raw bytes of the attachment and return.

Returns:InputStream

an InputStream from which the Base64 encoded AttachmentPart can be read.

Exceptions
SOAPException:
if there is no content set into this AttachmentPart object or if there was a data transformation error.
Since
1.6, SAAJ 1.3
getContentback to summary
public abstract Object getContent() throws SOAPException

Gets the content of this AttachmentPart object as a Java object. The type of the returned Java object depends on (1) the DataContentHandler object that is used to interpret the bytes and (2) the Content-Type given in the header.

For the MIME content types "text/plain", "text/html" and "text/xml", the DataContentHandler object does the conversions to and from the Java types corresponding to the MIME types. For other MIME types,the DataContentHandler object can return an InputStream object that contains the content data as raw bytes.

A SAAJ-compliant implementation must, as a minimum, return a java.lang.String object corresponding to any content stream with a Content-Type value of text/plain, a javax.xml.transform.stream.StreamSource object corresponding to a content stream with a Content-Type value of text/xml, a java.awt.Image object corresponding to a content stream with a Content-Type value of image/gif or image/jpeg. For those content types that an installed DataContentHandler object does not understand, the DataContentHandler object is required to return a java.io.InputStream object with the raw bytes.

Returns:Object

a Java object with the content of this AttachmentPart object

Exceptions
SOAPException:
if there is no content set into this AttachmentPart object or if there was a data transformation error

public abstract InputStream getRawContent() throws SOAPException

Gets the content of this AttachmentPart object as an InputStream as if a call had been made to getContent and no DataContentHandler had been registered for the content-type of this AttachmentPart.

Note that reading from the returned InputStream would result in consuming the data in the stream. It is the responsibility of the caller to reset the InputStream appropriately before calling a Subsequent API. If a copy of the raw attachment content is required then the getRawContentBytes API should be used instead.

Returns:InputStream
