Pessoal,

Estou com um erro muito loco de jstl aqui, não sei o que esta acontecendo pois tentei detudo e nda da certo, a estrutura que eu estou usando é struts, TomCat 5.5, JDBC, etc…

vou colocar o código abaixo, se souberem de algo fico muito grato.

Action:

public ActionForward find( ActionMapping pMapping, ActionForm pForm, HttpServletRequest pRequest, HttpServletResponse pResponse ) throws Exception {
		
		MenuForm form = (MenuForm) pForm;
		
		MenuServiceImpl menuServiceImpl = new MenuServiceImpl();
		
		List lList = menuServiceImpl.find();
		
		pRequest.setAttribute("menu", lList);
		
		return pMapping.findForward(FORWARD);
		
	}

Service:

public List find() throws Exception {

		List lReturn = new ArrayList();
		
		MenuDAOImpl menuDAOImpl = new MenuDAOImpl();
		
		List<Menu> lList = menuDAOImpl.find();
		
		lReturn.add(lList);
		
		return lReturn;
	}

DAO:

public List find() {
		
		List lReturn = new ArrayList();
		ResultSet rs;
		
		try {
			con = Conn.conection();
			
			StringBuffer sb = new StringBuffer("select * from TDomainMenu");
			Statement stmt = con.createStatement();
			rs = stmt.executeQuery(sb.toString());
			
			if (rs.next()){
				do{
					Menu menu = new Menu();
					menu.setIDMenu(rs.getInt("IDMenu"));
					menu.setCaption(rs.getString("Caption"));
					menu.setURL(rs.getString("URL"));
					lReturn.add(menu);
				}while(rs.next());
				
			}
			
			Conn.closeConn();
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	
		return lReturn;
	}

JSP:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

</html:form>

Struts-config:

	</plug-in>  

	
	
	
</struts-config>

Ele retorna a lista da action preenchido, tudo ok…só na hora da leitura do jsp que dá esse erro:

<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean" %>

Ajuda…

Leozin
Leozin

Fala velho

tenta baixar esse jar e colocar no teu lib

fsalex
fsalex

Pessoal,

Achei o problema principal era que estava faltando colocar o jar da versao certa coloquei o standars e o jstl 1.0.2 só que surgiu um outro problema não esta fazendo a leitura da saida do <c:out

<c:forEach items="${menu}" var="menu">
         <c:out value="${menu.caption}"/>
</c:forEach>

A saida que deveria ser o arrayList esta sendo essa abaixo :

${menu.caption}

Alguem sabe?

Vlw…

fabiozoroastro
fabiozoroastro

Cara, eu não li o tópico inteiro pra saber se ainda está dando erro mas tem uma coisa que está “irritando os meus olhos” no seu código. :slight_smile:

<c:forEach items="${menu}" var="menu">  
             <c:out value="${menu.caption}"/>  
    </c:forEach>

No var, coloque outro nome diferente da sua collection.
Ex.:

<c:forEach items="${menu}" var="obj">  
             <c:out value="${obj.caption}"/>  
    </c:forEach>

Aêeeee!

fsalex
fsalex

Fabio,

Eu alterei isso tbm só que continua o mesmo erro.

o que eu vi que pode estar causando algo é que quando chamo o core do c assim:

<%@taglib uri=?http://java.sun.com/jsp/jstl/core? prefix=?c?%>

da erro na busca da url

e quando chamo assim:
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix=“c” %>

funciona.

Eu tenho o tld, mas será que pode ser isso?

Vlw

fabiozoroastro
fabiozoroastro

Mas está com ponto de interrogação ou aspas?

<%@taglib uri=?http://java.sun.com/jsp/jstl/core? prefix=?c?%>

ou

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

???

fsalex
fsalex

Então,

Esta com aspas, é que eu esqueci de por como código:

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

foi mal…vlw

fabiozoroastro
fabiozoroastro

Posta seu jsp completo aqui pra gente te ajudar. Abraço.

fsalex
fsalex

Ta Ae o jsp:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@page language="java" contentType="text/html; charset=ISO-8859-1"
	pageEncoding="ISO-8859-1"%>
	
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %> 
<%@ taglib uri="/WEB-INF/tld/fmt.tld" prefix="fmt" %>
<%@ taglib uri="/WEB-INF/tld/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/tld/struts-bean.tld" prefix="bean" %>


<html:form action="homePin.do" method="post">
<html:hidden property="method" value="" />


	<c:forEach items="${menu.Menu}" var="obj">
		<c:out value="${obj.caption}"/>
	</c:forEach>

</html:form>

vlw…

fabiozoroastro
fabiozoroastro

Opa, mas então o erro só acontece se você declarar a utilização do c.tld usando a url externa?

fsalex
fsalex

Então,

Esse erro consegui resolver…era a compatibilidade de jar com o meu jsp.

Vlw
