在java webmethods中关闭下载窗口后无法重定向

Question

在Java中的Web方法应用程序中，我选择一个文件并下载它。当下载窗口关闭时，我将控件定向回父页面。我通过创建一个IPortletURL调用BasePortletPageBean.createRenderURL()来实现它，将其基本URL设置为我要重定向的portlet别名。然后调用FacesContext重定向方法。它在WebMethods8.0中运行良好，我是在WindowsXP机器上开发的。现在我将同一个项目导入到安装了WebMethods8.2的Windows7机器上，但现在它不工作了。请帮帮我

 public String downloadMaster() {


    List<Object> selectedRows = getFnamesProvider2().getSelectedRows();

    if (getFnamesProvider2().getSelectedRows() != null
            && getFnamesProvider2().getSelectedRows().size() != 0) {

        for (Iterator iterator = selectedRows.iterator(); iterator
                .hasNext();) {

            com.webmethods.caf.FileNames details = (com.webmethods.caf.FileNames) iterator
                    .next();


            System.out.println("Iterator Output!!!!!!!!!!!!!!!!!!!!!!!"

确保您始终使用完整路径，Webmethods 8.2还需要URL或图像等任何资源的完整路径。 这可能是你的问题的一个原因
