* object (<CODE>con</CODE> in the following line of code). The <CODE>String</CODE> passed to the

* URL for the schema. <PRE> MessageFactory mf = con.createMessageFactory(schemaURL); </PRE> </LI>
* <p/>
* <LI> Calls the method <CODE>createMessage</CODE> on the <CODE> MessageFactory</CODE> object. All
* messages produced by this <CODE>MessageFactory</CODE> object will have the header information
* appropriate for the messaging profile that was specified when the <CODE>MessageFactory</CODE>
* object was created. <PRE> SOAPMessage m = mf.createMessage(); </PRE> </LI> </UL> It is also
* possible to create a <CODE>MessageFactory</CODE> object using the method
* <CODE>newInstance</CODE>, as shown in the following line of code. <PRE> MessageFactory mf =
* MessageFactory.newInstance(); </PRE> A standalone client (a client that is not running in a
* container) can use the <CODE>newInstance</CODE> method to create a <CODE>MessageFactory</CODE>
* object.
* <p/>
* <P>All <CODE>MessageFactory</CODE> objects, regardless of how they are created, will produce
* <CODE>SOAPMessage</CODE> objects that have the following elements by default:</P>
* <p/>
* <UL> <LI>A <CODE>SOAPPart</CODE> object</LI>
* <p/>
* <LI>A <CODE>SOAPEnvelope</CODE> object</LI>
* <p/>
* <LI>A <CODE>SOAPBody</CODE> object</LI>
* <p/>
* <LI>A <CODE>SOAPHeader</CODE> object</LI> </UL> If a <CODE>MessageFactory</CODE> object was
* created using a <CODE>ProviderConnection</CODE> object, which means that it was initialized with
* a specified profile, it will produce messages that also come prepopulated with additional entries
* in the <CODE>SOAPHeader</CODE> object and the <CODE>SOAPBody</CODE> object. The content of a new
* <CODE>SOAPMessage</CODE> object depends on which of the two <CODE>MessageFactory</CODE> methods
* is used to create it.
* <p/>
* <UL> <LI><CODE>createMessage()</CODE> -- message has no content<BR> This is the method clients
* would normally use to create a request message.</LI>
* <p/>
* <LI><CODE>createMessage(MimeHeaders, java.io.InputStream)</CODE> -- message has content from the
* <CODE>InputStream</CODE> object and headers from the <CODE> MimeHeaders</CODE> object<BR> This
* method can be used internally by a service implementation to create a message that is a response
* to a request.</LI> </UL>
