Chamar método na EL

kaahxd · Novembro 12, 2012, 12:07pm

Como faço para chamar um método na view com EL? por exemplo de quero o autorizacao.getNome(); uso ${autorizacao.nome} e para outros métodos como faço? Por exemplo para chamar o método totalAutorizado(); como ficaria? Tentei fazer com o método isValido(); porém retornou null pointer exception, segue o que fiz:

métdo isValido()

	public boolean isValido() {
		Autorizacao autorizacao = new Autorizacao();
		if (autorizacao.getValidade().after(Calendar.getInstance())) {
			return false;
		}
		return true;
	}

Na view

<c:if test="${autorizacao.valido}">                               
	<c:set var="qnta" value="${qnta + autorizacao.quantidade}" /> 
</c:if>

Erro:

Alguém pode ajudar?

Seu problema não está em como chamar, mas que você tem um nullpointer aqui:
java.lang.NullPointerException
at br.com.e2s.modelo.residuo.Autorizacao.isValido(Autorizacao.java:115)

Qual objeto está null nesse método?

kaahxd · Novembro 12, 2012, 1:02pm

Veja:

<td id="qa_${residuo.id}">                                               
<c:set var="qnta" value="0" />                                           
<c:forEach var="autorizacao" items="${audao.lista}">                     
	<c:if test="${autorizacao.residuo.id eq residuo.id }">               
		<c:if test="${autorizacao.valido}">                              
			<c:set var="qnta" value="${qnta + autorizacao.quantidade}" />
		</c:if>                                                          
	</c:if>                                                              
</c:forEach>                                                             
${qnta}                                                                  
</td>

Nesse trecho da view ele tem algumas condições para adicionar um valor de autorização. Toda autorização tem uma validade, queria através do método Valido verificar se autorização está vencida ou não, caso não esteja vencida, acrescenta seu valor a variavel “qnta”.

Não sei se ficou claro, qualquer coisa só falar

Não sei se ficou claro, qualquer coisa só falar[/quote]Vou fazer de novo a pergunta, você viu no método quem está null? Todo nullpointer exception tem origem em algum valor que você está acessando com “.” mas ele está null.

kaahxd · Novembro 12, 2012, 2:25pm

Creio que seja o getValidade no If, por isso postei o que fiz na view para ver se ta com algum problema

Hebert_Coelho · Novembro 12, 2012, 2:29pm

[quote=kaahxd]Creio que seja o getValidade no If, por isso postei o que fiz na view para ver se ta com algum problema [/quote]Você debugou? Basta debugar que você vai ver onde está null.

kaahxd · Novembro 12, 2012, 3:08pm

Na área de debug não consegui ver nada familiar, creio que estou fazendo de forma incorreta o debug sendo que estou com um projeto web, adicionei um break point na linha do if com teste ${autorizacao.valido} e na sessão de variaveis apareceu da seguinte forma:

this	residuo_jsp  (id=361)

Todos os campos quando chamo o método isValido estão Nulls O.o

autorizacao	Autorizacao  (id=84)	
	autorizacao	null	
	fornecedor	null	
	id	null	
	inicioVigencia	null

kaahxd · Novembro 12, 2012, 3:47pm

Visto que estava apresentando tudo null, resolvi passar a autorizacao no contrutor do método e ver o que acontecia, porém me deparei com outro erro, veja:

Novo método:

	public boolean isValido(Autorizacao autorizacao) {
		if (autorizacao.getValidade().after(Calendar.getInstance())) {
			return false;
		}
		return true;
	}
