Class MondrianOlap4jEngineDriver

java.lang.Object

      mondrian.olap4j.MondrianOlap4jEngineDriver

All Implemented Interfaces:

Driver

public class MondrianOlap4jEngineDriver
extends MondrianOlap4jDriver

Olap4j driver for Mondrian that behaves as a server.

Unlike the client driver MondrianOlap4jDriver, this driver knows the list of schemas and catalogs, by parsing datasources.xml.

Since olap4j is a superset of JDBC, you register this driver as you would any JDBC driver:

Class.forName("mondrian.olap4j.MondrianOlap4jEngineDriver");

Then create a connection using a URL with the prefix "jdbc:mondrian:engine:". For example,

import java.sql.Connection;
import java.sql.DriverManager;
import org.olap4j.OlapConnection;

Connection connection =
DriverManager.getConnection(
"jdbc:mondrian:engine:Schema=FoodMart");
OlapConnection olapConnection =
connection.unwrap(OlapConnection.class);

Note how we use the java.sql.Connection#unwrap(Class) method to down-cast the JDBC connection object to the extension OlapConnection object. This method is only available in the JDBC 4.0 (JDK 1.6 onwards).

Connection properties

The driver supports the same set of properties as a traditional mondrian connection. See RolapConnectionProperties. Properties that allow the client to make connections to arbitrary databases ("Jdbc", "JdbcUser", "JdbcPassword", "Catalog") may be disabled.
