Specifying the data to retrieve from a POJO
BIRT reports must use data that is structured as a table consisting of rows and columns. For a POJO data set to return data in this format, you map methods or members of a POJO class to columns.
Listing 4‑1 shows an example of a class that represents music CDs. The class describes the members and uses pairs of get and set methods to persist the data. To create a data set using this class, you would map the get methods to columns.
