Reading SVG with java

Hello,

I'm doing a project where I must read an SVG file and get some data from it
using java. I was having success in my reading until yesterday.
A couple of weeks ago, the project was working fine, so I decided to do some
other works. Yesterday, I wanted to work on that project and when I ran the
project, it appears an Exception:

java.io.IOException: Server returned HTTP response code: 500 for URL:

In this case I used javax.xml. I got the message (error) at the following
point: Document doc = docBuilder.parse(new File(xml_path));

I was using sax before, but I got the same error at the same line of code:
Document doc=builder.build(xml_path);

I don't know if the problem is with the sever. I need to fix this problem
and I don't know how. I appreciate if you can help me, or to get the reason
why is not working.

Thanks in advance,
