unknown protocol: c (JDOM a SAXBuilder)

Question

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 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)

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 ?

can you post the XML that is causing the problem? – beny23 Aug 30 '11 at 13:08 — beny23, Aug 30 '11 at 13:08

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

Agree. You can try something like `if(myUrl.getProtocol().equals("c")){myUrl = new URL("file://"+myUrl.toexternalform())}` – MrDrews Aug 30 '11 at 13:44

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.

Yup, you are so right, and as the OP mentioned this seems to be in issue in Java 1.6 and above only. – zEro Jun 13 '13 at 11:12

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);
