unknown protocol: c (JDOM a SAXBuilder)

问题

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
    at java.net.URL.<init>(URL.java:574)
    at java.net.URL.<init>(URL.java:464)

    at org.jdom.input.SAXBuilder.build(SAXBuilder.java:986)
    at com.foo.moo.MyClass.getValues(MyClass.java:321)

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 ?

回答1:

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:// or file://

Try file://c:/mylocalfile.xml

回答2:

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.

回答3:

I had a space in my file name

i solved it using an InputStream instead of the filename:

works:

fis = new FileInputStream(filename);
Document doc = new SAXBuilder().build(fis);

crashes:

Document doc = new SAXBuilder().build(filename);
