Field Detail

JDBC_LOCALE

public static final String JDBC_LOCALE

Name of property used by JDBC to hold locale. It is not hard-wired into DriverManager like "user" and "password", but we do expect any olap4j driver that supports i18n to use this property name.

Constructor Detail

XmlaHandler

public XmlaHandler(XmlaHandler.ConnectionFactory connectionFactory,
                   String prefix)

Creates an XmlaHandler.

The connection factory may be null, as long as you override getConnection(String, String, String, Properties).

Parameters:

connectionFactory - Connection factory

prefix - XML Namespace. Typical value is "xmla", but a value of "cxmla" works around an Internet Explorer 7 bug

Method Detail

getExtra

public static XmlaHandler.XmlaExtra getExtra(OlapConnection connection)

getConnection

public OlapConnection getConnection(XmlaRequest request,
                                    Map<String,String> propMap)

Returns a new OlapConnection opened with the credentials specified in the XMLA request or an existing connection if one can be found associated with the request session id.

Parameters:

request - Request

propMap - Extra properties

isValidXsdInt

public static boolean isValidXsdInt(long l)

process

public void process(XmlaRequest request,
                    XmlaResponse response)
             throws XmlaException

Processes a request.

Parameters:

request - XML request, for example, "".

response - Destination for response

Throws:

XmlaException - on error

writeDatasetXmlSchema

static void writeDatasetXmlSchema(SaxWriter writer,
                                  mondrian.xmla.XmlaHandler.SetType settype)

Computes the XML Schema for a dataset.

Parameters:

writer - SAX writer

settype - rowset or dataset?

See Also:

RowsetDefinition.writeRowsetXmlSchema(SaxWriter)

writeEmptyDatasetXmlSchema

static void writeEmptyDatasetXmlSchema(SaxWriter writer,
                                       mondrian.xmla.XmlaHandler.SetType setType)

getConnection

protected OlapConnection getConnection(String catalog,
                                       String schema,
                                       String role)
                                throws XmlaException

Gets a Connection given a catalog (and implicitly the catalog's data source) and the name of a user role.

If you want to pass in a role object, and you are making the call within the same JVM (i.e. not RPC), register the role using MondrianServer.getLockBox() and pass in the moniker for the generated lock box entry. The server will retrieve the role from the moniker.

Parameters:

catalog - Catalog name

schema - Schema name

role - User role name

Returns:

Connection

Throws:

XmlaException - If error occurs

getConnection

protected OlapConnection getConnection(String catalog,
                                       String schema,
                                       String role,
                                       Properties props)
                                throws XmlaException

Gets a Connection given a catalog (and implicitly the catalog's data source) and the name of a user role.

If you want to pass in a role object, and you are making the call within the same JVM (i.e. not RPC), register the role using MondrianServer.getLockBox() and pass in the moniker for the generated lock box entry. The server will retrieve the role from the moniker.

Parameters:

catalog - Catalog name

schema - Schema name

role - User role name

props - Properties to pass down to the native driver.

Returns:

Connection

Throws:

XmlaException - If error occurs
