GeneratePDF with JasperReports Library and MongoDB

Question

Here is my GeneratePdf.java Import ...

  public class GeneratePdf {
        public static void main(String[] args) {
        try {
            JRDataSou         


        

Answer 1

Using the JRBeanCollectionDataSource is not the right way to go about using the MongoDB connector. Take a look at this test that comes with the Jaspersoft MongoDB Connector source:

MongoDbDatasource/src/test/java/com/jaspersoft/mongodb/ReportTest.java

Both the binary connector and the source are on the project page.

To keep this answer self-contained, here's a code snippet showing how to fill a MongoDB report. It's a modified extract from the file I mention above.

String mongoURI = "mongodb://bdsandbox6:27017/test";
MongoDbConnection connection = null;
Map<String, Object> parameters = new HashMap<String, Object>();
try {
  connection = new MongoDbConnection(mongoURI, null, null);
  parameters.put(MongoDbDataSource.CONNECTION, connection);
  File jasperFile;
  jasperFile = new File("MongoDbReport.jasper");
  JasperCompileManager.compileReportToFile("MongoDbReport.jrxml", "MongoDbReport.jasper");
  JasperFillManager.fillReportToFile("MongoDbReport.jasper", parameters);
  JasperExportManager.exportReportToPdfFile("MongoDbReport.jrprint");
}
} catch (Exception e) {
  e.printStackTrace();
} finally {
  if (connection != null) {
    connection.close();
  }
}

You need to add following line:

JRProperties.setProperty("net.sf.jasperreports.query.executer.factory.MongoDbQuery", "com.jaspersoft.mongodb.query.MongoDbQueryExecuterFactory");

Verify path in datasource jar file, e.g. js-mongodb-datasource-0.5.0
