then in your JavaBean, add the following for a button to be called from Xpages

	public void doRunJasperReportsCSVBarCharts() throws NotesException{
		  // set up the loggers
	      Log log = LogFactory.getLog(RunJasperReportsWithCSVDataSourceBean.class);
	      Log debug = LogFactory.getLog("DEBUG");
	      // tell what they are
	      System.out.println("log is a " + log.getClass().getName());
	      System.out.println("debug is a " + debug.getClass().getName());
	      log.info("an info message");
	      debug.debug("a debug message");

	      log.info("another info message");
	      debug.debug("another debug message");
		//get the current database being used
		Database database= (Database) FacesContext.getCurrentInstance()
		.resolveVariable(FacesContext.getCurrentInstance(), "database");
		System.out.println("Database Obtained..." + database);
		//Run the agent after all items have been submitted to page
