It's OpenSource and great for commercial products. There are several products like JasperReports Server and Jaspersoft Studio. Especially the Jaspersoft Studio is very useful for creating reports with a WYSIWYG editor. Simply use the tool and create your reports.

The most insteresting part is the integration of Jasperreports in a JVx application. It's super easy to start Jasperreports programmatically:

//database connection
DBAccess dba = DBAccess.getDBAccess("jdbc:hsqldb:hsql://localhost/personsdb", "sa", "");
dba.open();

HashMap<String, Object> hmpParams = new HashMap<String, Object>();
hmpParams.put("ID" , Integer.valueOf(1));
//external connection as parameter
hmpParams.put("REPORT_CONNECTION", dba.getConnection()); // String

// compile report
JasperReport jasperReport = JasperCompileManager.compileReport(ResourceUtil.getResourceAsStream("Leaf_Grey.jrxml"));
 
// fill report (connection as parameter)
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, hmpParams);
// fill report (hardcoded connection)
//JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, hmpParams, dba.getConnection());
 
File fiPdf = File.createTempFile("report", ".pdf");

// export report to PDF
JasperExportManager.exportReportToPdfFile(jasperPrint, fiPdf.getAbsolutePath());

// JVx usage
RemoteFileHandle rfh = new RemoteFileHandle(fiPdf);

// open with PDF viewer
//FileViewer.open(fiPdf);

Our example was created with Jasperreports 6.3.1. The library has some dependencies:

  • Apache Commons Logging
  • Apache Commons Digester 2
  • Apache Commons Collections
  • Apache Commons BeanUtils
  • iText 2.1.7 (unpatched) or iText 2.1.7.js5 (jaspersoft patched)

A complete Eclipse example project can be found here. It connects to a HSQLDB with following tables:

CREATE CACHED TABLE POSTLEITZAHLEN
(
 ID INTEGER IDENTITY,
 PLZ VARCHAR(5) NOT NULL,
 ORT VARCHAR(100) NOT NULL,
 CONSTRAINT UK_POST_PLZ_ORT UNIQUE(PLZ, ORT)
)

CREATE CACHED TABLE STRASSEN
(
 ID INTEGER IDENTITY,
 NAME VARCHAR(200) NOT NULL,
 CONSTRAINT UK_STRA_NAME UNIQUE(NAME)
)

CREATE CACHED TABLE ADRESSEN
(
 ID INTEGER IDENTITY,
 POST_ID INTEGER NOT NULL,
 STRA_ID INTEGER NOT NULL,
 HAUSNUMMER INTEGER NOT NULL,
 STIEGE INTEGER,
 TUERNUMMER INTEGER,
 CONSTRAINT FK_ADRE_POST_ID FOREIGN KEY (POST_ID) REFERENCES POSTLEITZAHLEN (ID),
 CONSTRAINT FK_ADRE_STRA_ID FOREIGN KEY (STRA_ID) REFERENCES STRASSEN (ID)
)

CREATE CACHED TABLE ANREDEN
(
 ID INTEGER IDENTITY,
 BEZEICHNUNG VARCHAR(20) NOT NULL,
 CONSTRAINT UK_ANRE_BEZEICHNUNG UNIQUE(BEZEICHNUNG)
)

CREATE CACHED TABLE TITEL
(
 ID INTEGER IDENTITY,
 BEZEICHNUNG VARCHAR(20) NOT NULL,
 CONSTRAINT UK_TITE_BEZEICHNUNG UNIQUE(BEZEICHNUNG)
)

CREATE CACHED TABLE PERSONEN
(
 ID INTEGER IDENTITY,
 PERS_ID INTEGER,
 ANRE_ID INTEGER NOT NULL,
 TITE_ID INTEGER,
 ADRE_ID INTEGER,
 VORNAME VARCHAR(100) NOT NULL,
 NACHNAME VARCHAR(100) NOT NULL,
 GEBDAT DATE NOT NULL,
 CONSTRAINT FK_PERS_ANRE_ID FOREIGN KEY (ANRE_ID) REFERENCES ANREDEN (ID),
 CONSTRAINT FK_PERS_TITE_ID FOREIGN KEY (TITE_ID) REFERENCES TITEL (ID),
 CONSTRAINT FK_PERS_PERS_ID FOREIGN KEY (PERS_ID) REFERENCES PERSONEN (ID),
 CONSTRAINT FK_PERS_ADRE_ID FOREIGN KEY (ADRE_ID) REFERENCES ADRESSEN (ID)
)

The final step for the integration into a JVx application is the integration in a life-cycle object, e.g.

public IFileHandle createReport() throws Exception
{
    JasperReport jasperReport = JasperCompileManager.compileReport(
                                   ResourceUtil.getResourceAsStream("person.jrxml"));
     
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,
                                                           null,
                                                           getDBAccess().getConnection());
     
    File fiPdf = File.createTempFile("report", ".pdf");
   
    // export report to PDF
    JasperExportManager.exportReportToPdfFile(jasperPrint, fiPdf.getAbsolutePath());
   
    return new RemoteFileHandle(fiPdf);
}
