java - 没有协议(protocol)错误，java，上传文件时

Question

我正在运行一个 jar 文件，但当我想上传一个文件(存在)时出现以下错误。

ufuoma@ufuoma-VirtualBox:~/ltserver$ java -jar lt4el-cmd.jar send -l en "file:Here.doc"
ERROR [Thread-1]: Error getting url: no protocol: Here.doc (AppInterface.java:140)

AppInterface.java文件中产生错误的部分是(为了便于跟踪，我注释掉了140行):

public void run() {
        byte[] anaContent;
        byte[] ontContent;
        byte[] dceContent;
        Document doc = null;

        try {
        //create new Document object, initial status == FAILED
            DocumentStatus status = new DocumentStatus(DocumentStatus.Status.PROCESSING, "Preprocessing");
            doc = new Document(id, LangCode.toInt(lang), status, true, 0);
            doc.lockRW();

            //add the document and process it
            docControl.addDocument(doc);
        } catch (Exception e) {
            String error = "Error adding document: "+e.getMessage();
    /*Line 140*/ log.error(error);
            try {
                if (doc != null) {
                    docControl.setDocumentStatus(doc, DocumentStatus.Status.FAILED, error);
                    doc.unlockRW();
                }
                db.sync();    //FIXME
            } catch (Exception ex) {
                // ignore
            }
            return;
        }

        try {
            // save the document data
            log.debug("reading URL...");
            docControl.setDocumentStatus(doc, DocumentStatus.Status.PROCESSING, "Reading source document");
            readURL(url);
        } catch (Exception e) {
            String error = "Error getting url: "+e.getMessage();
            log.error(error);
            try {
                docControl.setDocumentStatus(doc, DocumentStatus.Status.FAILED, error);
                doc.unlockRW();
                db.sync();    //FIXME
            } catch (Exception ex) {
                // ignore
            }
            return;

发送命令的选项是:

- send a LO (test.xml) into the LTserver, language is set to Czech. test.xml must reside in the Docs directory as specified in the property file.

    $ java -jar lt4el-cmd.jar send -l cs "test LO.xml"

By default, ID is a file name ("test LO.xml" in our example). To assign different ID, you can prepend it to the file name (separated by a colon). E.g. to give the learning object ID "lo1":

    $ java -jar lt4el-cmd.jar send -l cs "lo1:test LO.xml"

我试过以下方法:

java -jar lt4el-cmd.jar send -l en "file:Here.doc"
java -jar lt4el-cmd.jar send -l en "Here.doc"
java -jar lt4el-cmd.jar send -l en "file:/path/to/Here.doc"
java -jar lt4el-cmd.jar send -l en "/path/to/Here.doc"

但是还是报同样的错误。我不知道问题出在哪里。谢谢

规范实际上需要一个 HTTP url，我从我的本地系统给它一个文件作为 file:///，它无法解析为 FTP。因此，我得到:ERROR [Thread-1]: Error getting url: no protocol: 。 . .。为了解决这个问题，我将文件放在 XAMPP 服务器上 - path/to/opt/lampp/htdocs/file - 并可以通过以下方式对其进行评估:http://localhost:file 这是一个有效的 HTTP url。
