Ran into a percular problem today.  When saving an xml file that has a '#' character in it the file is save up to the point of the hash.  For example.  'Test #2.xml' would be saved as 'Test'.

I created a short program below to demonstrate the problem.
import java.io.File;

import javax.swing.JFileChooser;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class saveFile {

	public static void main(String[] args) {
	   try {
		   
		   JFileChooser chooser = new JFileChooser();
			chooser.setDialogTitle("Save Project");
			chooser.setAcceptAllFileFilterUsed(false);
			File file = null;
			if(chooser.showDialog(null, "Save") == JFileChooser.APPROVE_OPTION){
				file = chooser.getSelectedFile();

				DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance();
				DocumentBuilder docBuilder = dbfac.newDocumentBuilder();
				Document doc = docBuilder.newDocument();
				
				Element project = doc.createElement("project");
				
				project.setAttribute("title", "test");
				
				doc.appendChild(project);
				
				Source source = new DOMSource(doc);
				
				System.out.println(file.getAbsolutePath());
				
				Result result = new StreamResult(file);
				
				Transformer xformer = TransformerFactory.newInstance().newTransformer();
				xformer.transform(source, result);
			}
			
	   } catch (Exception ex){
		   ex.printStackTrace();
	   }
		
	}

}

Are you sure it's not more to do with the space?

positive - "Test White Space.xml" is fine. while "Test White Space #2.xml" will be written to disk as "Test White Space"

this seeems to be something similar to your problem in TransfioomFactory or something

pound sign may be a problem in the filename when it is used in the link on the web
(as poud is used to point to some location on the pag)

for_yan is right.  His link has this link in it which explains the issue:

http://bugs.sun.com/bugdatabase/view_bug.do?bug%5Fid=4294586

And seaching for "java "pound sign" path bug", it looks like it's still a problem 10+ years later.

>>http://stackoverflow.com/questions/1858221/pound-sign-in-directory-name-in-java-how-to-read-it

is not relevant, as

a. the StreamResult ctor is the one in question here, not StreamSource
b. the parameter is of type File anyway, not String

In fact, if you do the very reverse of what is suggested at the link that for_yan posted (use String and not File), you'll probably have not problem (i don't)


Result result = new StreamResult(file.getAbsolutePath());
                Transformer xformer = TransformerFactory.newInstance()
                                                        .newTransformer();
                xformer.transform(source, result);
