How Create Cubes in Jasperserver 5 Enterprise

Hello Community, 

I am using Jasperserver 5.0 Enterprise Edition. I have some question while creating schema. How can i create this schema. if i want create a olap view they want a schema file. Is this file to create manually like the example foodmart?

If i read the user guide it only says that i have to create a schema file, but not how to create this.

For MDX query, same question , Do I have to write it manually or some software can generate it?

Thanks in advance.
