Method Detail

init

public void init(javax.servlet.ServletConfig servletConfig)
          throws javax.servlet.ServletException

Specified by:

init in interface XmlaRequestCallback

Throws:

javax.servlet.ServletException

processHttpHeader

public boolean processHttpHeader(javax.servlet.http.HttpServletRequest request,
                        javax.servlet.http.HttpServletResponse response,
                        Map<String,Object> context)
                          throws Exception

Description copied from interface: XmlaRequestCallback

Process the request header items. Specifically if present the Authorization and Expect headers. If the Authorization header is present, then the callback can validate the user/password. If authentication fails, the callback should throw an XmlaException with the correct XmlaConstants values. The XmlaRequestCallback.Helper class contains the authorizationException method that can be used by a callback to generate the XmlaException with the correct values. If the Expect header is set with "100-continue", then it is upto the callback to create the appropriate response and return false. In this case, the XmlaServlet stops processing and returns the response to the client application. To facilitate the generation of the response, the XmlaRequestCallback.Helper has the method generatedExpectResponse that can be called by the callback.

Note that it is upto the XMLA client to determine whether or not there is an Expect header entry (ADOMD.NET seems to like to do this).

Specified by:

processHttpHeader in interface XmlaRequestCallback

Returns:

true if XmlaServlet handling is to continue and false if there was an Expect header "100-continue".

Throws:

Exception

preAction

public void preAction(javax.servlet.http.HttpServletRequest request,
             Element[] requestSoapParts,
             Map<String,Object> context)
               throws Exception

Description copied from interface: XmlaRequestCallback

This is called after the headers have been process but before the body (DISCOVER/EXECUTE) has been processed.

Specified by:

preAction in interface XmlaRequestCallback

Throws:

Exception

generateSessionId

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

Description copied from interface: XmlaRequestCallback

The Callback is requested to generate a sequence id string. This sequence id was requested by the XMLA client and will be used for all subsequent communications in the Soap Header block. Implementation can return null if they do not want to generate a custom session ID, in which case, the default algorithm to generate session IDs will be used.

Specified by:

generateSessionId in interface XmlaRequestCallback

Parameters:

context - The context of this query.

Returns:

An arbitrary session id to use, or null.

postAction

public void postAction(javax.servlet.http.HttpServletRequest request,
              javax.servlet.http.HttpServletResponse response,
              byte[][] responseSoapParts,
              Map<String,Object> context)
                throws Exception

Description copied from interface: XmlaRequestCallback

This is called after all Mondrian processing (DISCOVER/EXECUTE) has occurred.

Specified by:

postAction in interface XmlaRequestCallback

Throws:

Exception
