I am creating a simple reporting program using java and iReport (from jasper), which is supposed to create a report in pdf showing PCs with their IP address, their location, whether it's idle or not at the moment (handled by another system), and a list of projects it is currently attached to (managed elsewhere, too).
I'm using iReport for this matter, and have created a dummy collection generating class as follows:
public class PCReports {
public static java.util.Collection PC_collection;
public static java.util.Collection generateCollection() {
PC_collection = new ArrayList<PCLineDTO>();
PCLineDTO line = new PCLineDTO();
line.setIP("192.168.1.1");
line.setLab("location");
line.setActive(true);
line.addProjectName("project1");
line.addProjectName("project2");
line.addProjectName("project3");
PC_collection.add(line);
line = new PCLineDTO();
line.setIp("192.168.1.2");
line.setLab("location2");
line.setActive(false);
line.addProjectName("project1");
line.addProjectName("project2");
PC_collection.add(line);
return PC_collection;
}
}
The entity class in this case being:
public class PCLineDTO {
private String ip;
private String lab;
private Boolean active;
private ArrayList<String> projects;
}
After some searching around the Internet, I found a way to do something similar, using subreports.
The thing is, I don't know how to print a collection of strings passed as a dataSource to this subreport.
In the examples I found on the Internet, for each item in the master collection, the subreports were passed a collection of objects -with their own getter methods for each attribute- instead of a collection of strings as is the case here. In those cases, they accessed the values they needed to use via the iReport syntax, which I was not able to use, for example:
$F{project}
Since iReport looks for a getProject method contained within the objects it receives, but in this case it's a simple String object (without a getProject method, as it were).
