With your data populated, you can now create a data source in JasperReports Server that points to that data.
A data source is a connection that points to a database or other data store. Data sources define where data is stored for populating reports and views. There are several types of data sources, based on the type of connection or location of the data. For OLAP processing, you can use JDBC, JNDI, and bean data sources.
For a complete introduction to data sources, including defining a data source in JasperReports Server, see the JasperReports Server Administrator Guide.
