Fala galera!!!
Eu sou novo na programação e estou precisando de uma ajuda, estou tentando fazer um for dentro dos scriplets mas esta dando erro. É a parte do read do meu crud. Quando eu aço o for através da camada controller ele funciona, mas na pagina jsp ele da um erro.
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@page import="model.JavaBeans"%>
<%@page import="java.util.ArrayList"%>
<%
ArrayList<JavaBeans> lista = (ArrayList<JavaBeans>)request.getAttribute("contatos");
for (int i = 0; i < lista.size(); i++){
out.print(lista.get(i).getIdlista());
}
%>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Lista de Tarefas</title>
<link rel="stylesheet" href="css/styles.css">
</head>
<body>
<div id= "login-container">
<h1>Lista de Tarefas</h1>
<table>
<thead>
<tr>
<th>Código</th>
<th>Titulo</th>
<th>Descrição</th>
<th>Data</th>
<th>Status</th>
<th>Prioridade</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<form name="frmContato" action="listarTarefa">
<input type="submit" value="Cadastrar" onclick="validar()">
</form>
</div>
<script src="scripts/validador.js"></script>
</body>
</html>
E esse é o erro

Bom dia gostaria de compartilhar um erro que vem ocorrendo há muito tempo na empresa em que trabalho. Porem nunca foi identificada a causa origem do mesmo, Isso ocorre de forma aleatória não tem data nem hora, acontece de repente. Sendo obrigado ao 'fechamento forçado' do sistema que pode gerar problemas na base. Em anexo imagem do Erro. Grato

Como posso resolver ou alguma coisa dessa natureza?
Obrigado desde já!

ola pessoal, Estou com um problema chato que não consigo resolver. Criei um datatable com cellEditor dentro de uma tab e, dentro dessa tab, eu coloquei um ajax que muda a lista do datatable toda vez que muda para outra tab. O problema é que, quando eu clico em outra tab e carrega o outro datatable eu perco a edição das células e só aparece o output da célula. Gostaria de uma ajuda pra saber o que está acontecendo e como resolver: xhtml <p:tabView value="#{cadastroContasBean.listaTabela}" dynamic="true" closeable="true" activeIndex="#{cadastroContasBean.idTabela}" var="tabela" style="heigth:100%;width:100%" id="tabView"> <p:tab title="tab" closable="true" id="tab"> <div> <p:dataTable binding="#{cadastroContasBean.dataTable}" var="gasto" value="#{cadastroContasBean.listaGasto}" scrollable="true" scrollHeight="150" editable="true" editMode="cell" id="Tabela" widgetVar="wTabela"> <p:column headerText="Nome"> <p:cellEditor> <f:facet name="output"> <p:outputLabel value="#{gasto.nome}" /> </f:facet> <f:facet name="input"> <p:inputText id="inputTextNome" required="true" value="#{cadastroContasBean.nome}" style="width:96%" binding="#{cadastroContasBean.inputTextNome}"> <p:ajax event="change" update="Tabela" listener="#{cadastroContasBean.atualizaVT('inputTextNome')}" execute="inputTextNome" process="@this"> </p:ajax> </p:inputText> </f:facet> </p:cellEditor> </p:column> <p:column headerText="Quantidade"> <p:cellEditor> <f:facet name="output"> <p:outputLabel value="#{gasto.quantidade}" /> </f:facet> <f:facet name="input"> <p:inputText id="inputQtd" required="true" value="#{cadastroContasBean.qtd}" style="width:96%" onkeydown="MascaraNumero()" onkeyup="MascaraNumero()" binding="#{cadastroContasBean.inputTextQtd}"> <p:ajax event="change" update="Tabela" listener="#{cadastroContasBean.atualizaVT('inputTextQtd')}" execute="inputQtd" process="@this" /> </p:inputText> </f:facet> </p:cellEditor> </p:column> <p:column headerText="Valor"> <p:cellEditor> <f:facet name="output"> <p:outputLabel value="#{gasto.valor}"> <f:convertNumber currencySymbol="R$" type="currency" /> </p:outputLabel> </f:facet> <f:facet name="input"> <p:inputText id="inputValor" required="true" value="#{cadastroContasBean.valor}" style="width:96%" binding="#{cadastroContasBean.inputTextValor}"> <f:convertNumber pattern="#,##0.00"></f:convertNumber> <f:validator validatorId="MoedaValidator" /> <p:ajax event="change" update="Tabela" listener="#{cadastroContasBean.atualizaVT('inputTextValor')}" execute="inputValor" process="@this"> </p:ajax> </p:inputText> </f:facet> </p:cellEditor> </p:column> <p:column headerText="Valor Total" id="vt"> <p:outputLabel id="outputVT" value="#{gasto.valorTotal}"> <f:convertNumber currencySymbol="R$" type="currency" /> </p:outputLabel> </p:column> </p:dataTable> <div id="addGasto"> <p:commandButton value="Add gasto" style="width:100%" actionListener="#{cadastroContasBean.addGasto}" update="Tabela"></p:commandButton> </div> </div> <div> <p:outputLabel value="Comentários: " for="comentario"></p:outputLabel> <p:inputTextarea value="#{tabela.comentarios}" id="comentario" autoResize="true" style="width: 100%; height: 50%"></p:inputTextarea> </div> </p:tab> <p:ajax event="tabChange" execute="tab" listener="#{cadastroContasBean.mudaTab}" process="@this" /> </p:tabView> MB public void mudaTab(TabChangeEvent event) { tabelaAtual = (Tabela)event.getData(); idTabela =(tabelaAtual).getId(); listarGastos(); } public void listarGastos(){ listaGasto = tabelaAtual.getListaGastos(); } Tabela public class Tabela { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Integer id; private String comentarios; @OneToMany (mappedBy="tabela") private List<Gastos> listaGastos = new ArrayList<Gastos>(); @ManyToOne private MesAno mesano; public List<Gastos> getListaGastos() { return listaGastos; } public void setListaGastos(List<Gastos> listaGastos) { this.listaGastos = listaGastos; } public MesAno getMesano() { return mesano; } public void setMesano(MesAno mesano) { this.mesano = mesano; } public String getComentarios() { return comentarios; } public void setComentarios(String comentarios) { this.comentarios = comentarios; } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } } Obs: não consigo identar o xhtml ¬¬
