action中抛出的异常，默认就会弹出对应的异常信息

        public static InputStream downloadFile(String fileName,String fYWZJ,String fXMMC) throws Exception{
                FileInputStream in = null;
                String bizRoot = FileSystemWrapper.instance().getBase();
                String cachePath = bizRoot + "/samba/fileCache/";
                String cacheFileName = cachePath + fileName;
                try {
                        //同步远程服务器文件到本地服务器
                        String sambaFile ="/"+ fXMMC + "/" + fileName;
                        SambaFileUtil.downloadFileToLocal(sambaFile, cacheFileName);
                       
                        // 返回文件流
                        File file = new File(cacheFileName);
                        in = new FileInputStream(file);
                       
                        //记录操作日志
                        SysOperationUtil.insertSysOperation("下载", "交付资料仓库-项目", "从/"+ fXMMC +"下，下载文件"+ fileName, "成功");
                } catch (Exception e) {
                        throw new Exception("下载附件失败，请重新下载！"+e);
                }
                return in;
        }


这是我的java文件，并没弹出来，后台打印了，而且下载任务打开了，下载了一个空文件。

确认执行try的语句都错误吗？

是的，单步调试都到了catch里面，控制台也打印了异常信息。

这个是get的方式应该不会拦截window.open

可以用form表单post的方式提交

Uncaught TypeError: Cannot read property 'convertURL' of undefined

对应的错误代码是
var url = justep.Request.convertURL("/UI/system/components/excel/export/download.j"+"?action=downloadFile&$downloadFilename=" + encodeURI(fileName));
开发环境是bex_3.6

就参考文档中心的上传实现啊，那个就是按照，再写个案例也是一样的

文档中心的上传实现在那里啊，可以麻烦给个链接吗，没找到。

jishuang

var url = require.toUrl("$UI/demo/actions/process/invokeAction/downloadFile.j" + "?action=downloadFileAction&fileName=" + encodeURI(fileName) + '&$downloadFilename='
                                + encodeURI(downloadFilename));
                url = biz.Request.setBizParams(url);


/UI2/SA/doc/docCenter/docCenter.js中upload方法

payProjectFileListMainActivity.js:52 Uncaught TypeError: Cannot read property 'setBizParams' of undefined

提供解决方案，能否先测试通过啊。。。按照你回复的http://bbs.wex5.com/forum.php?mo ... 4354&extra=page%3D1
照着里面写的，复制了一份对应提供的.j文件，根本就报错

/UI2/system/resources/src右键设置为源码路径

还是没有提示异常信息。。。 单步看到断点了， 到了异常处理的类。

后台打印了log
