Description

Interface Summary

Detail A container for DetailEntry objects.

DetailEntry The content for a Detail object, giving details for a SOAPFault object.

Name A representation of an XML name.

Node A representation of a node (element) in an XML document.

SOAPBody An object that represents the contents of the SOAP body element in a SOAP message.

SOAPBodyElement A SOAPBodyElement object represents the contents in a SOAPBody object.

SOAPConstants The definition of constants pertaining to the SOAP 1.1 protocol.

SOAPElement An object representing an element of a SOAP message that is allowed but not specifically prescribed by a SOAP specification.

SOAPEnvelope The container for the SOAPHeader and SOAPBody portions of a SOAPPart object.

SOAPFault An element in the SOAPBody object that contains error and/or status information.

SOAPFaultElement A representation of the contents in a SOAPFault object.

SOAPHeader A representation of the SOAP header element.

SOAPHeaderElement An object representing the contents in the SOAP header part of the SOAP envelope.

Text A representation of a node whose value is text.

Class Summary

AttachmentPart A single attachment to a SOAPMessage object.

MessageFactory A factory for creating SOAPMessage objects.

MimeHeader An object that stores a MIME header name and its value.

MimeHeaders A container for MimeHeader objects, which represent the MIME headers present in a MIME part of a message.

SOAPConnection A point-to-point connection that a client can use for sending messages directly to a remote party (represented by a URL, for instance).

SOAPConnectionFactory A factory for creating SOAPConnection objects.

SOAPElementFactory Deprecated. - Use javax.xml.soap.SOAPFactory for creating SOAPElements.

SOAPFactory SOAPFactory is a factory for creating various objects that exist in the SOAP XML tree.

SOAPMessage The root class for all SOAP messages.

SOAPPart The container for the SOAP-specific portion of a SOAPMessage object.

Exception Summary

SOAPException An exception that signals that a SOAP exception has occurred.

Package javax.xml.soap Description

Provides the API for creating and building SOAP messages. This package is defined in the SOAP with Attachments API for Java^TM (SAAJ) 1.1 specification.

The API in the javax.xml.soap package allows you to do the following:

create a point-to-point connection to a specified endpoint
create a SOAP message
create an XML fragment
add content to the header of a SOAP message
add content to the body of a SOAP message
create attachment parts and add content to them
access/add/modify parts of a SOAP message
create/add/modify SOAP fault information
extract content from a SOAP message
send a SOAP request-response message

In addition the APIs in the javax.xml.soap package extend their counterparts in the org.w3c.dom package. This means that the SOAPPart of a SOAPMessage is also a DOM Level 2 Document, and can be manipulated as such by applications, tools and libraries that use DOM (see http://www.w3.org/DOM/ for more information). It is important to note that, while it is possible to use DOM APIs to add ordinary DOM nodes to a SAAJ tree, the SAAJ APIs are still required to return SAAJ types when examining or manipulating the tree. In order to accomplish this the SAAJ APIs (specifically SOAPElement.getChildElements()) are allowed to silently replace objects that are incorrectly typed relative to SAAJ requirements with equivalent objects of the required type. These replacements must never cause the logical structure of the tree to change, so from the perspective of the DOM APIs the tree will remain unchanged. However, the physical composition of the tree will have changed so that references to the nodes that were replaced will refer to nodes that are no longer a part of the tree. The SAAJ APIs are not allowed to make these replacements if they are not required so the replacement objects will never subsequently be silently replaced by future calls to the SAAJ API.

What this means in practical terms is that an application that starts to use SAAJ APIs on a tree after manipulating it using DOM APIs must assume that the tree has been translated into an all SAAJ tree and that any references to objects within the tree that were obtained using DOM APIs are no longer valid. Switching from SAAJ APIs to DOM APIs is not allowed to cause invalid references and neither is using SAAJ APIs exclusively. It is only switching from using DOM APIs on a particular SAAJ tree to using SAAJ APIs that causes the risk of invalid references.
