resultSet = statement.executeQuery(query);
JRResultSetDataSource resultSetDataSource =
new JRResultSetDataSource(resultSet);
model.put("datasource", resultSetDataSource);
"datasource", resultSetDataSource);
datasource", resultSetDataSource);
return model;
public void setDataSource (DataSource dataSource)
Note that our implementation of the handleRequest() method is very simple. It
returns a new instance of org.springframework.web.servlet.ModelAndView . We
pass the view name �defined in the application context) and a map containing the
data to be displayed to the constructor of ModelAndView , and return it.
The getModel() method of JasperSpringController executes an SQL query in the
database and populates an instance of JRResultSetDataSource with the results.
Finally, we need to write a JSP that will invoke JasperSpringController .

Notice that no special JSP tag libraries are needed to integrate with Spring. After we
deploy our web application and direct our browser to http://localhost:8080/
jasperspring/generate_report.jsp , we should see a web page like the following:
