Report UI Add-on provides an easy way to render JasperReports in Vaadin applications through DynamicJasper.

Basic usage

Say, you have the following domain/entity/Java Bean class:

public class Call {

    private Long id;
    private String client;
    private String phoneNumber;
    private City city; // enum
    private LocalDateTime startTime;
    private Integer duration;
    private Status status; // enum

    ... getters and setters ...
}

 

You can create a new report and add it to any Vaadin layout as follows:

PrintPreviewReport<Call> report = new PrintPreviewReport<>(Call.class);
report.setItems(Repository.findAll());
layout.addComponent(report);

 

Advanced usage

You can optionally set the order of the columns as follows:

PrintPreviewReport<Call> report = new PrintPreviewReport<>(Call.class, "client", "city", "phoneNumber", "startTime", "duration", "status");

 

If you prefer, you can use the default constructor to avoid creating the columns automatically. In that case, you can use the getReportBuilder() method to set the columns manually:

PrintPreviewReport<Call> report = new PrintPreviewReport<>();
report.getReportBuilder()
        .setMargins(20, 20, 40, 40)
        .setTitle("Call report")
        .addAutoText("For internal use only", AutoText.POSITION_HEADER, AutoText.ALIGMENT_LEFT, 200, headerStyle)
        .addAutoText(LocalDateTime.now().toString(), AutoText.POSITION_HEADER, AutoText.ALIGNMENT_RIGHT, 200, headerStyle)
        .addAutoText(AutoText.AUTOTEXT_PAGE_X_OF_Y, AutoText.POSITION_HEADER, AutoText.ALIGNMENT_RIGHT, 200, 10, headerStyle)
        .setPrintBackgroundOnOddRows(true)
        .addColumn(city = ColumnBuilder.getNew()
                .setColumnProperty("city", City.class)
                .setTitle("City")
                .build())
        .addGroup(new GroupBuilder()
                .setCriteriaColumn((PropertyColumn) city)
                .build())
        .addColumn(ColumnBuilder.getNew()
                .setColumnProperty("client", String.class)
                .setTitle("Client")
                .build())
        .addColumn(ColumnBuilder.getNew()
                .setColumnProperty("phoneNumber", String.class)
                .setTitle("Phone number")
                .build())
        .addColumn(ColumnBuilder.getNew()
                .setColumnProperty("startTime", LocalDateTime.class)
                .setTitle("Date")
                .setTextFormatter(DateTimeFormatter.ISO_DATE.toFormat())
                .build())
        .addColumn(ColumnBuilder.getNew()
                .setColumnProperty("startTime", LocalDateTime.class)
                .setTextFormatter(DateTimeFormatter.ISO_LOCAL_TIME.toFormat())
                .setTitle("Start time")
                .build())
        .addColumn(ColumnBuilder.getNew()
                .setColumnProperty("duration", Integer.class)
                .setTitle("Duration (seconds)")
                .build())
        .addColumn(ColumnBuilder.getNew()
                .setColumnProperty("status", Status.class)
                .setTitle("Status").build());

 

See the DynamicJasper documentation for more configuration examples.

You can get a StreamResource for downloading the report in various formats. For example:

StreamResource streamResource = report.getStreamResource(
        "report.pdf", itemsSupplier, PrintPreviewReport.Format.PDF);
Anchor pdf = new Anchor(streamResource, "Download PDF");

 

Apache POI is required when using some of the exporting methods:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.10-FINAL</version>
</dependency>

 

In order to render charts you have to configure an ImageServlet. For example:

@WebServlet("/report-image")
public static class ReportsImageServlet extends ImageServlet {
}

You can configure the URL pattern using the setImageServletPathPattern method (default to report-image?image={0}).
