另外一般会WinRAR打包，
你找找看下载栏里有没有这样的文件，有的话，下载好，和电影文件放在一起，
改成一样的文件名，比如123.avi和123.srt，或者123.avi，123.idx，123.sub。
这样用暴风或者终极解码之类的播放器就可以看到字幕了。
form表单提交文件，建议用smartupload上传，暂存在web服务器目录下，然后稍微一下下面的代码，ftp上传后，删除暂存文件，okimport java.io.File

=====================================
jsp上传部分
===================================
<form method="post" name="uploadform" id="uploadform" action="upload" ENCTYPE="multipart/form-data">
<input type="hidden" name="service" value="com.jbsoft.i2hf.corpor.services.CstBatchBizServices.exclUpload"/>
<table cellspacing="0" cellpadding="0">
<tr>
<td width="20%" align="right">上传本地文件：</td>
<td width="80%"><input class="" style="width:300px" type="file" width="300px" name="exclname" id="exclname"/></td>
</tr>
</table>
</form>
============================================
上传的servlet用的是smartupload
，部分代码可以参考一下：
==========================================
SmartUpload su = new SmartUpload()
su.setCharset("UTF-8")
su.initialize(getServletConfig(), request, response)
su.setMaxFileSize(10240000)
su.setTotalMaxFileSize(102400000)
su.setAllowedFilesList("xls")
su.upload()
===========================================
代码里面有一些客户的信息，不能全部给你哈
JSP将HTML的表单数据提交生成一个XML文件的方法：1、定义表单，封装id，firstName和lastName
<form:form modelAttribute="person">
<form:hidden path="id" />
<fieldset>
<div class="form-row">
<label for="firstName"><fmt:message key="person.form.firstName"/>:</label>
<span class="input"><form:input path="firstName" /></span>
</div>
<div class="form-row">
<label for="lastName"><fmt:message key="person.form.lastName"/>:</label>
<span class="input"><form:input path="lastName" /></span>
</div>
<div class="form-buttons">
<div class="button">
<input type="submit" id="save" name="_eventId_save" value="<fmt:message key="button.save"/>"/>
<input type="submit" name="_eventId_cancel" value="Cancel"/>
</div>
</div>
</fieldset>
</form:form>
2、提交到servlet后，调用构造xml的java方法：
try {
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance()
DocumentBuilder docBuilder = docFactory.newDocumentBuilder()
// root elements
Document doc = docBuilder.newDocument()
Element rootElement = doc.createElement("company")
doc.appendChild(rootElement)
// staff elements
Element staff = doc.createElement("Staff")
rootElement.appendChild(staff)
// set attribute to staff element
Attr attr = doc.createAttribute("id")
attr.setValue("1")
staff.setAttributeNode(attr)
// shorten way
// staff.setAttribute("id", "1")
// firstname elements
Element firstname = doc.createElement("firstname")
firstname.appendChild(doc.createTextNode("yong"))
staff.appendChild(firstname)
// lastname elements
Element lastname = doc.createElement("lastname")
lastname.appendChild(doc.createTextNode("mook kim"))
staff.appendChild(lastname)
// nickname elements
Element nickname = doc.createElement("nickname")
nickname.appendChild(doc.createTextNode("mkyong"))
staff.appendChild(nickname)
// salary elements
Element salary = doc.createElement("salary")
salary.appendChild(doc.createTextNode("100000"))
staff.appendChild(salary)
// write the content into xml file
TransformerFactory transformerFactory = TransformerFactory.newInstance()
Transformer transformer = transformerFactory.newTransformer()
DOMSource source = new DOMSource(doc)
StreamResult result = new StreamResult(new File("d:\\person.xml"))；
transformer.transform(source, result)
System.out.println("File saved!")
} catch (ParserConfigurationException pce) {
pce.printStackTrace()
} catch (TransformerException tfe) {
tfe.printStackTrace()
}
3、构造完成：
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<company>
<staff id="1">
<firstname>yong</firstname>
<lastname>mook kim</lastname>
<nickname>mkyong</nickname>
<salary>100000</salary>
</staff>
</company>
