| public void | doPost(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response)Handles a POST request from a client. The request is assumed
to contain a SOAP message with the HTTP binding.
try {
// Get all the HTTP headers and convert them to a MimeHeaders object
MimeHeaders mimeHeaders = getMIMEHeaders(request);
// Create a SOAPMessage from the content of the HTTP request
SOAPMessage message = messageFactory.createMessage(mimeHeaders,
request.getInputStream());
// Let the subclass handle the message
SOAPMessage reply = onMessage(message);
// If there is a reply, return it to the sender.
if (reply != null) {
// Set OK HTTP status, unless there is a fault.
boolean hasFault = reply.getSOAPPart().getEnvelope().getBody().hasFault();
response.setStatus(hasFault ?
HttpServletResponse.SC_INTERNAL_SERVER_ERROR :
HttpServletResponse.SC_OK);
// Force generation of the MIME headers
if (reply.saveRequired()) {
reply.saveChanges();
}
// Copy the MIME headers to the HTTP response
setHttpHeaders(reply.getMimeHeaders(), response);
// Send the completed message
OutputStream os = response.getOutputStream();
reply.writeTo(os);
os.flush();
} else {
// No reply - set the HTTP status to indicate this
response.setStatus(HttpServletResponse.SC_NO_CONTENT);
}
} catch (SOAPException ex) {
throw new ServletException("SOAPException: " + ex);

| private javax.xml.soap.MimeHeaders | getMIMEHeaders(javax.servlet.http.HttpServletRequest request)Creates a MIMEHeaders object from the HTTP headers
received with a SOAP message.

while (enum.hasMoreElements()) {
String headerName = (String)enum.nextElement();
String headerValue = request.getHeader(headerName);

super.init(config);
try {
messageFactory = MessageFactory.newInstance();
} catch (SOAPException ex) {
throw new ServletException("Failed to create MessageFactory", ex);
}

| protected abstract javax.xml.soap.SOAPMessage | onMessage(javax.xml.soap.SOAPMessage message)Method implemented by subclasses to handle a received SOAP message.
|
| private void | setHttpHeaders(javax.xml.soap.MimeHeaders mimeHeaders, javax.servlet.http.HttpServletResponse response)Converts the MIMEHeaders for a SOAP message to
HTTP headers in the response.
