$P{userId}]

Download jasperreport engine

final Map<String,Object> parameter = new HashMap<String, Object>();
parameter.put("userId", 1l);
JasperFillManager.fillReport("filename.jasper", parameter, getData());

// set your own params for this method
public JRDatasource getData() { 
  // initialize a collection of Objects
  // Oh yes the query
  final Query query = getQuery("from SomeObject");
  final List<SomeObject> collection = (List<SomeObject>)query.list();
  return new JRBeanCollectionDataSource(collection);
}

Another possibility 

JasperFillManager.fillReport(jasperReport, parameter, connection);
