Question

我对<ice:outputResouce>有疑问。它按预期工作，但当我按下载按钮时，我得到一个错误：HTTP Status 404 - Resource not found

这是我的环境：

Icefaces 2.0
on Liferay 6.0.6 via PortletFaces
在JBoss 5.1上运行

public Resource getPdfResource()方法：

 public Resource getPdfResource() {
    System.out.println("GET PDF Ressource: " + getPDF());
    if (getPDF() == null) {
        return null;
    }
    try {
        File f = PDFFileUtils.getFile(getPDF());
        Resource res = new ByteArrayResource(
                IOUtils.toByteArray(new FileInputStream(f)));
        return res;
    } catch (IOException e) {
    //...
    }
    //...
    return null;
}

以及<ice:outputResouce>

中的.xhmtl块

<ice:outputResource
   label="#{i18n['download']} #{publishBackingBean.pdfName}"
   type="button"
   shared="false"
   fileName="#{publishBackingBean.pdfName}"
  resource="#{publishBackingBean.pdfResource}" attachment="true">
</ice:outputResource>

resouceservlet工作正常。

有人有想法吗？我认为liferay＆amp; |可能存在问题portletbridge ...

编辑：

我现在已经在FileResouce：

中添加了一些调试消息

Resource res = new FileResource(f){
            /* (non-Javadoc)
             * @see com.icesoft.faces.context.FileResource#calculateDigest()
             */
            @Override
            public String calculateDigest() {
                System.out.println("Calc Dig calld: "+ super.calculateDigest());
                Thread.dumpStack();
                return super.calculateDigest();
            }
            /* (non-Javadoc)
             * @see com.icesoft.faces.context.FileResource#open()
             */
            @Override
            public InputStream open() throws IOException {
                System.out.println("open called");
                return super.open();
            }
            /* (non-Javadoc)
             * @see com.icesoft.faces.context.FileResource#lastModified()
             */
            @Override
            public Date lastModified() {
                System.out.println("lm called");
                return super.lastModified();
            }
        };

调用gets的唯一方法是calculateDigest：
