Build a one page Website BIRT java

Description I need a website with Java/Apache Tomcat 8 that displays only one webpage with a report designed with BIRT. The one page application should be able to dynamically set the data-source and data-set for the BIRT report by utilizing jdbc adapter to get data from a database. The eventual database is going to be AS400/DB2, but for this particular task you can use a mongoDB or any other open source database engine (I prefer NoSQL but relational is fine too if that will make the job get done faster) that you are familiar with. I can provide additional details on the table/data that should will be displayed. The webpage should refresh itself so that the report displays new data every x number of seconds. This setting should also come from a table - settings where we can change the frequency. There is no user authentication required or any other bells or whistles. Just a dynamic Birt report/dashboard sort of an application with one page display for now. There will be more work involved in this project so if this first task is completed with satisfaction, there will be more new work. The underlying table definition that the data will persist and will populate the report is as follows: DATASOURCE/DATASET INFORMATION: Tablename: user_task Columns: colname, datatype, [length (bytes)],description user_task_id, int, 4, this will be a PK field. locname,string, 20, an alphanumeric value that indicates the location where the work is being performed. username,string,20,alphanumeric field that contains the users identification/name. taskname,string,20,alphanumeric field that contains the name of the task. taskcategory,string,20, category of the task. orderid,string,25, alphanumeric value indicating the order name. itemid,string,25, item identifier itemcat,string,30, category of the item or product qty,numeric(8.3),,a numeric value as per datatype defined. startdt,datetime,, a datetime field indicating when the user started the task. enddt,datetime,, a datetime field indicating when the user stopped the task. WEBPAGE - Webpage will have the following BIRT reports will be as follows: Report Page1. Report Page 1 will display a BIRT designed report with one bar chart on the top and corresponding detail in a grid at the bottom. CART: A bar chart showing data from the grid as explained below. The bar chart x axis will be username, and y axis will be unitsperhour value. GRID: A grid structure showing the data from the table user_task. Each line in the grid will be grouped by the username and will have the following columns: username, task_date, sum(qty), UnitsPerHour explanation: username = self explanatory. task_date = the task_date is only the date part from column startdt unitsperhour = sum(qty) divided by (diff between max(enddt) and min(startdt) in hours).
