Help! Error in Basic interface for ad hoc queries

[Zhiyong Cheng]

Hi,

I am a newbie to Mondrian. I tried to set up Mondrian + MySQL.
I followed the instructions on websites :http://business-
intelligence.phi-integration.com/2008/04/mondrian-mysql-setup.html and
http://pentaho-en.phi-integration.com/mondrian/configuring-mondrian-sample.
It's very helpful. When I go to the Mondrian examples page, all tests
run successfully except Basic interface for ad hoc queries, I get the
list of queries and I can show all the queries, no problem. But when I
go to process the MDX query I get this error message:

mondrian.olap.MondrianException: Mondrian Error:Internal error:

I have already change the web.xml and mondrian.properties:
web.xml:
<context-param>
<param-name>connectString</param-name>
<param-value>Provider=mondrian;Jdbc=jdbc:mysql://localhost/
foodmart;JdbcUser=root;JdbcPassword=123456;Catalog=/WEB-INF/queries/
FoodMart.xml;JdbcDrivers=com.mysql.jdbc.Driver;</param-value>
</context-param>
.....
<servlet>
<servlet-name>MDXQueryServlet</servlet-name>
<servlet-class>mondrian.web.servlet.MdxQueryServlet</servlet-
class>
<init-param>
<param-name>connectString</param-name>
<param-value>@mondrian.webapp.connectString@</param-value>
</init-param>
</servlet>

mondrian.properties:
mondrian.webapp.connectString=Provider=mondrian;Jdbc=jdbc:mysql://
localhost/foodmart;JdbcUser=root;JdbcPassword=123456;Catalog=/WEB-INF/
queries/FoodMart.xml;JdbcDrivers=com.mysql.jdbc.Driver;


By the way, my Operating System is windows 7. Tomcat 6.0.32, Mondrian
3.2.1
Can you help me fix this problem?
Many Thanks!
