Bom dia Pessoal,

Gostaria de utilizar o jasper para realizar o relatorios em java,
meu banco está em CSV, dentro do jasper está tudo certo,
só queria que o botão do java abrisse uma viewer, mas aparece essa mensagem

try {  
					   URL  arquivo = getClass().getResource("/report/Blank_A4_Landscape.jasper"); 
					   System.out.println(arquivo);
			           Map<String, Object> map = new HashMap<String, Object>();
			           map.put("nome","Kassio");
			           JasperReport jasperReport = (JasperReport) JRLoader.loadObject(arquivo);  
			           JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, map); 
			           JasperViewer jrviewer = new JasperViewer(jasperPrint, false);  
			           jrviewer.setVisible(true); 
			           jrviewer.toFront();
			         }catch (Exception ex) {  
			            System.err.println(ex);
			        }

E em seguida “java.lang.NullPointerException”

Não tem nada após esse NullPointerException?

Você não pôs um printStackTrace no tratamento da exceção. :frowning:

} catch (Exception ex) {
    System.err.println(ex); // isso aqui não diz nada de útil
}

Faça assim:

} catch (Exception ex) {
    ex.printStackTrace();
}

Foi mal, tinha colocado na outra função, segue:

Você não vai usar um data source pro seu Jasper?
Se vai usar somente o mapa de parâmetros, tenta assim:

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, map, new JREmptyDataSource());

Fiz algumas alterações no código porém acontece o mesmo:

meuBean bean1 = new meuBean("João", 31);
	        	meuBean bean2 = new meuBean("Fernando", 43);
	        	meuBean bean3 = new meuBean("Luis", 24);
	        	Collection<meuBean> lista = new ArrayList<meuBean>();
	        	lista.add(bean1);
	        	lista.add(bean2);
	        	lista.add(bean3); 
				
				
				try {
					String caminho = "/relatorio/Flower_Landscape.jasper";
					InputStream relJasper = getClass().getResourceAsStream(caminho);
					JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(lista);
					
					Map parametro = new HashMap();
					JasperPrint impressao = null;
					
					impressao = JasperFillManager.fillReport(relJasper, parametro,ds);
					JasperViewer viewer = new JasperViewer(impressao,true);
					viewer.setVisible(true);
					
				} catch (Exception e2) {
					// TODO: handle exception
					e2.printStackTrace();

Gostaria de usar o Filed $F{nome}
Quando chamo no java, ele retira essa field, só queria que ele carregasse esa Field,

Se alguém souber estou parado nessa classe, ele chama o jasper, porém ele não encontra os dados do xml,

Dentro do jasper está como uma field de nome e idade, o xml encontra o csv

Estou chegando próximo se alguém tiver uma ideia por qual motivo não está indo me ajuda
No segundo gráfico não está recebendo os valores do parâmetro do primeiro gráfico que é o main.

Java:

try {
			InputStream relJasper = getClass().getResourceAsStream("C://algumacoisa.jasper");
			JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(
					lista);

			Map<String, Object> parametro = new HashMap();
			JasperPrint impressao = null;
			parametro.put("SubDataSource", ds);

			impressao = JasperFillManager.fillReport(relJasper, parametro, ds);
			JasperViewer viewer = new JasperViewer(impressao, false);
			viewer.setVisible(true);

		} catch (Exception e2) {
			// TODO: handle exception
			e2.printStackTrace();
		}

Jrxml:

Tentei seguir exemplo nesse site, mas, ele não traz resultado:

Conseguir resolver alterando o parametro para:

parametro.put("SubDataSource", **new JRBeanCollectionDataSource((Collection<meuBean>) lista));**
