Re: [dom4j-user] SAX Parse Exception

[Brian W. Young]

The error message is pretty accurate- since you're not loading your doc 
from a URL, there is no base URL to derive the relative URL of your 
DTD.  What does file.getContents() do? If it is just loading the 
contents of the file from disk into a string or something, you'd be 
better off just passing a URL to the sax reader.  Otherwise I believe 
you are able to set a base URL on the sax reader for entity resolution, 
you might give that a shot.

Hi,

I have the follow code to parse a file, and my file reference an 
external DTD ../style/modulesynopsis.dtd like this:

<?xml version="1.0"?>
<!DOCTYPE modulesynopsis SYSTEM "../style/modulesynopsis.dtd">
....
but I got an Nested exception: org.xml.sax.SAXParseException: Relative 
URI "../style/modulesynopsis.dtd"; can not be resolved without a base URI.

Could some one please tell me what did I miss?
And How can I switch to use xerces instead of crimson parser?
Thanks for any help
