The API in the
javax.xml.soap package allows you to do the following:
In addition the APIs in the
javax.xml.soap package extend
their counterparts in the
org.w3c.dom package. This means that
SOAPPart of a
SOAPMessage is also a DOM Level
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
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into an all SAAJ tree and that any references to objects within the tree that were obtained using DOM APIs are no longer valid.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.
There are several factories defined in the SAAJ API to discover and load specific implementation:
newInstance()method which uses a common lookup procedure to determine the implementation class:
javax.xml.soap.SOAPFactory). If such property exists then its value is assumed to be the fully qualified name of the implementation class. This phase of the look up enables per-JVM override of the SAAJ implementation.
Propertiesformat and typically located in the
confdirectory of the Java installation. It contains the fully qualified name of the implementation class with the key being the system property defined above.
ServiceLoaderclass, to attempt to locate and load an implementation of the service using the default loading mechanism.
SAAJMetaFactoryinstance is used to locate specific implementation (for
SOAPFactory) or platform default implementation is used (
SAAJMetaFactoryis used, its lookup procedure to get actual instance is performed.
