Mondrian XML/A server errors (app works fine with Olap4J API)

Question

I have set up Mondrian on JBoss and it works fine when running an MDX statement via the Olap4J API. But when I set up Mondrian as XML/A server, I get the exception below (in the server console) when trying to connect with Warehouse Explorer (aka Rex) with the URL http://localhost:8080/olap/xmla.

The error in Rex is:

This is my datasources.xml

<DataSource>
    <DataSourceName>Mondrian</DataSourceName>
    <DataSourceDescription>Mondrian XMLA</DataSourceDescription>
    <URL>http://localhost:8080/olap/xmla</URL>
    <DataSourceInfo>Provider=mondrian;Jdbc=jdbc:mysql://localhost:3306/foodmart;JdbcUser=uuuuu;JdbcPassword=pppp;JdbcDrivers=com.mysql.jdbc.Driver;</DataSourceInfo>
    <ProviderName>Mondrian</ProviderName>
    <ProviderType>MDP</ProviderType>
    <AuthenticationMode>Unauthenticated</AuthenticationMode>
    <Catalogs>
        <Catalog name="FoodMart">
            <Definition>/WEB-INF/FoodMart.xml</Definition>
        </Catalog>
    </Catalogs>
</DataSource>

And this is the exception:

Answer 1

This is how I fixed this problem: you have to add Catalog to DataSourceInfo (in addition to the Catalog element):

Provider=mondrian;Jdbc=jdbc:mysql://localhost:3306/foodmart;JdbcUser=uuuuu;JdbcPassword=ppppp;JdbcDrivers=com.mysql.jdbc.Driver;Catalog=/WEB-INF/FoodMart.xml
