Browsing my Google Analytics statistics, I realized there is a lot of people out there that are searching for ways to connect Microsoft SQL Server with olap4j.

Here is a nice example.
// We must use the XMLA driver.
Class.forName("org.olap4j.driver.xmla.XmlaOlap4jDriver");

// This code is for Java 5. With Java 6, you can directly
// unwrap the underlying connection with the .unwrap() call.
OlapConnection connection =
(OlapConnection) DriverManager.getConnection(

// This is the SQL Server service end point.
"jdbc:xmla:Server=http://example.com/olap/msmdpump.dll"

// Tells the XMLA driver to use a SOAP request cache layer.
// We will use an in-memory static cache.
+ ";Cache=org.olap4j.driver.xmla.cache.XmlaOlap4jNamedMemoryCache"

// Sets the cache name to use. This allows cross-connection
// cache sharing. Don't give the driver a cache name and it
// disables sharing.
+ ";Cache.Name=MyNiftyConnection"

// Some cache performance tweaks.
// Look at the javadoc for details.
+ ";Cache.Mode=LFU;Cache.Timeout=600;Cache.Size=100",

// XMLA is over HTTP, so BASIC authentication is used.
"username",
"password" );

// We can execute a query. MDX of course.
CellSet set = connection.createStatement().executeOlapQuery(
"SELECT {} ON COLUMNS FROM CUBE");
