Reporting tool

I want a reporting tool developed to generate reports from a small datawarehouse whose schema i will provide or we can work out later. Basically the backend database can be access or mysql. The application should involve a small applet or jsp pages which interact with a tomcat server on which servlets will run which deal with the backend database. Basically a 3 tier application. The schema will have between 5-7 tables. I will need the source code. Thanks
