This is a further sample which querying Sales Cube using JPivot interface. The cube data is derived from MySQL foodmart sample data which we can generate from Mondrian's zip bundle. The sales cube schema is defined in Foodmart.xml file.

  • Gender
  • Marital Status
  • Customers
  • Product
And 3 measures are displayed, they are :
  • Unit Sales
  • Store Cost
  • Store Sales

Configuration

Prerequisites Articles

File Configuration

Open and edit fourhier.jsp file - which should be located in your [TOMCAT_HOME]/webapps/mondrian/WEB-INF/queries folder - with your favourite text editor,  and edit <jp:mondrianQuery> with these following configurations :

fourhier.jsp

<jp:mondrianQuery
    id="query01"
    jdbcDriver="com.mysql.jdbc.Driver"
    jdbcUrl="jdbc:mysql://localhost/foodmart?user=your_username&password=your_password"
    catalogUri="/WEB-INF/queries/FoodMart.xml">
select {[Measures].[Unit Sales], [Measures].[Store Cost], [Measures].[Store Sales]} on columns,
{([Gender].[All Gender], [Marital Status].[All Marital Status],
  [Customers].[All Customers],
  [Product].[All Products] ) } on rows
  from Sales where ([Time].[1997])

</jp:mondrianQuery>


Note : [TOMCAT_HOME] is the folder where your Apache Tomcat installed. For example : C:\apache-tomcat-6.0.16

Testing

Open your Mondrian web application and click on the third sample from the index page (JPivot with 4 hierarchies). You should see an OLAP data table with a JPivot toolbar. Drill through some of the dimension level nodes.

For example, my web application is located at http://localhost:8080/mondrian and my "JPivot with 4 hierarchies" sample url is http://localhost:8080/mondrian/testpage.jsp?query=fourhier. Screenshot below shows the page that have been drillthrough at some nodes.
