未知协议：c（JDOM 和 SAXBuilder）
我正在使用 JDOM 和 SAXBuilder 来解析 XML 文件，并且我遇到了一个抛出此错误的文件问题：
java.net.MalformedURLException: unknown protocol: c
at java.net.URL.<init>(URL.java:574)
at java.net.URL.<init>(URL.java:464)
at java.net.URL.<init>(URL.java:413)

at org.jdom.input.SAXBuilder.build(SAXBuilder.java:986)
at com.foo.moo.MyClass.getValues(MyClass.java:321)
行是：
Document document = null;
document = sxb.build(files.elementAt(i)); // This one
在互联网上做了一些研究后，我认为该错误与 Java 1.6 有关。
你怎么认为 ？
I'm using JDOM with SAXBuilder to parse XML files, and I have a problem with a file which is throwing this error :
java.net.MalformedURLException: unknown protocol: c

And the line is :
Document document = null;
document = sxb.build(files.elementAt(i)); // This one
After doing some research on the internet, I think the error is related to Java 1.6.
What do you think ?

我的第一个猜测是您正在加载本地文件，例如：“c:/mylocalfile.xml”，
但是此 URL 不包含协议，例如
http://、ftp:// /或file://尝试 file://c:/mylocalfile.xml
My first guess is that you are loading a local file, like: "c:/mylocalfile.xml"
But this URL does not contain the protocol, like
http://,ftp://orfile://Try file://c:/mylocalfile.xml
实际上，我的文件夹名称中有空格导致了此错误。即使对于本地文件，JAVA 也有能力理解协议类型。
Actually, I had space in my folder name which caused this error. Even in case of local files JAVA has the capability of understanding the protocol types.
我的文件名中有一个空格，
我使用 InputStream 而不是文件名解决了它：

crashes:
I had a space in my file name
i solved it using an InputStream instead of the filename:
