Method Detail

init

public void init(ServletConfig servletConfig)
          throws ServletException

Description copied from class: XmlaServlet

Initializes servlet and XML/A handler.

Specified by:

init in interface Servlet

Overrides:

init in class XmlaServlet

Throws:

ServletException

getDocumentBuilderFactory

protected DocumentBuilderFactory getDocumentBuilderFactory()

unmarshallSoapMessage

protected void unmarshallSoapMessage(HttpServletRequest request,
                                     Element[] requestSoapParts)
                              throws XmlaException

Description copied from class: XmlaServlet

Implement to provide application specified SOAP unmarshalling algorithm.

Specified by:

unmarshallSoapMessage in class XmlaServlet

Throws:

XmlaException

handleSoapHeader

protected void handleSoapHeader(HttpServletResponse response,
                                Element[] requestSoapParts,
                                byte[][] responseSoapParts,
                                Map<String,Object> context)
                         throws XmlaException

See if there is a "mustUnderstand" header element. If there is a BeginSession element, then generate a session id and add to context Map.

Excel 2000 and Excel XP generate both a BeginSession, Session and EndSession mustUnderstand==1 in the "urn:schemas-microsoft-com:xml-analysis" namespace Header elements and a NamespaceCompatibility mustUnderstand==0 in the "http://schemas.microsoft.com/analysisservices/2003/xmla" namespace. Here we handle only the session Header elements

Specified by:

handleSoapHeader in class XmlaServlet

Throws:

XmlaException

generateSessionId

protected String generateSessionId(Map<String,Object> context)

getSessionId

protected String getSessionId(Element e,
                              Map<String,Object> context)
                       throws Exception

Throws:

Implement to handle XML/A request.

Specified by:

handleSoapBody in class XmlaServlet

Throws:

XmlaException

                                   byte[][] responseSoapParts)
                            throws XmlaException

Description copied from class: XmlaServlet

Implement to privode application specified SOAP marshalling algorithm.

Specified by:
