使用p：graphicImage的javax.el.PropertyNotFoundException

Question

我遇到了这个问题，我不知道为什么会这样，我尝试了很多东西，但是......没有成功，谢谢你的帮助。

这就是问题：

GRAVE: Servlet.service() para servlet [Faces Servlet] lanzó excepción
java.io.IOException: javax.el.PropertyNotFoundException: /catalogoAdmin.xhtml @16,40 value="#{catalogoBean.image}": Propiedad [image] no hallada en el tipo [beans.CatalogoBean]

这是我的代码：

方法Bean

public StreamedContent getImage() throws IOException {
        FacesContext context = FacesContext.getCurrentInstance();

        if (context.getCurrentPhaseId() == PhaseId.RENDER_RESPONSE) {
            return new DefaultStreamedContent();
        } else {
            String filename = context.getExternalContext().getRequestParameterMap().get("nombre");
            return new DefaultStreamedContent(new FileInputStream(new File("C:\\images/", filename)));          
        }
    }

XHTML

<h:form id="formImg">
            <p:graphicImage value="#{catalogoBean.image}"
                style="height:150px; width:150px;">
                <f:param name="nombre" value="ram.png" />
            </p:graphicImage>
        </h:form>
