Display JavaBean List Data with JRBeanCollectionDataSource

If you are working with JavaBeans and want to display data from a list of those beans in a JasperReports report, you can use the JRBeanCollectionDataSource class to easily create a data source for your report.

The first step is to create a list of your JavaBeans that you want to display in the report. Let's say you have a JavaBean class called Person with properties such as name, age, and address.

<pre>
public class Person {
  private String name;
  private int age;
  private String address;

  // getters and setters
}
</pre>

Now, you can create a list of Person objects and populate it with data:

<pre>
List<Person> personList = new ArrayList<>();
personList.add(new Person("John Doe", 30, "123 Main St."));
personList.add(new Person("Jane Smith", 25, "456 Oak Ave."));
// add more Person objects as needed
</pre>

Next, you can create a JRBeanCollectionDataSource object from the list of Person objects:

<pre>
JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(personList);
</pre>

Finally, you can pass the dataSource object as the data source for your JasperReport:

<pre>
JasperPrint print = JasperFillManager.fillReport(report, parameters, dataSource);
</pre>

With this approach, you can easily display data from a list of JavaBeans in your JasperReports report.
