JSF 1.2 Pegar nome de imagem dinâmica

Vivis.sf · Novembro 5, 2011, 9:13pm

Boa noite,

Sou novata com jsf e preciso pegar o nome da imagem ao ser clicada (ou um link ao lado) e que o nome da imagem seja enviado para uma classe java, pois o nome da dela é o seu id.

Listo algumas imagens de acordo com o tipo de produto selecionado:

&lt;h:dataTable value="#{buscaPorTipoMaisVotado.listaProdutos}" var="movel" border="1"&gt;
	&lt;h:column&gt;
		&lt;h:graphicImage id="img" value="/imagens/#{movel.idProduto}.jpg" width="100" height="100"/&gt;
	&lt;/h:column&gt;
&lt;/h:dataTable&gt;

Alguém pode me ajudar?

Grata,

Viviane

Olá Vivi use o setPropertyActionListener para setar o valor assim:

    <h:dataTable value="#{buscaPorTipoMaisVotado.listaProdutos}" var="movel" border="1">  
        <h:column>  
            <h:graphicImage id="img" value="/imagens/#{movel.idProduto}.jpg" width="100" height="100"/>  
             <f:setPropertyActionListener target="#{seuOutroBean.variavelSetada}" value="#{movel.idProduto}" />
        </h:column>  
    </h:dataTable>

Assim quando o cara clicar na imagem o idProduto será enviado para a variavelSetada da sua classe, simples assim

Coloquei do jeito que você me falou, mas acho que estou fazendo mais alguma coisa errada, pois está retornando erro:

&lt;html&gt;
&lt;body&gt;
	&lt;f:view&gt;
			&lt;h:outputText value="Moveis mais votados dos tipos selecionados: " /&gt;
			&lt;h:panelGrid columns="1" border="1"&gt;

				&lt;h:dataTable value="#{buscaPorTipoMaisVotado.listaProdutos}"
					var="movel" border="1"&gt;
					&lt;h:column&gt;
						&lt;h:graphicImage id="img" value="/imagens/#{movel.idProduto}.jpg"
							width="100" height="100" /&gt;
						&lt;f:setPropertyActionListener target="#{mostrarMovel.idProduto}" value="#{movel.idProduto}" /&gt;
					&lt;/h:column&gt;
				&lt;/h:dataTable&gt;
			&lt;/h:panelGrid&gt;
	&lt;/f:view&gt;
&lt;/body&gt;
&lt;/html&gt;

Em “mostrarMovel” tenho o atributo idProduto, com seu devido getter e setter.

Arrumei e coloquei o seguinte código:

&lt;h:dataTable value="#{buscaPorTipoMaisVotado.listaProdutos}"
					var="movel" border="1"&gt;
					&lt;h:column&gt;
						&lt;h:commandLink value="Imgagem #{movel.idProduto}" action="#{mostrarMovel.mostrarMovel}"&gt;
							&lt;f:setPropertyActionListener
								target="#{mostrarMovel.idProduto}" value="#{movel}" /&gt;
						&lt;/h:commandLink&gt;
					&lt;/h:column&gt;
				&lt;/h:dataTable&gt;

mas ele simplesmente não faz nada, o que estou fazendo de errado?
