I have files on my file system, on Windows XP. I want to parse them using Java (JRE 1.6).
Problem is, I don't understand how Java and Xerces work together when the file path has spaces in it.
If the file has no spaces in its path, all works fine.
If there are spaces, I may have this kind of trouble, even if I call the parser with a FileInputStream instance :

(It says unknown protocol: d because, I guess, the file is on the D drive.)
Has anyone any clue of why that happens, and how to circumvent the problem ? I tried to supply my own EntityResolver but my log tells me it is not even called before the crash.
EDIT:
Here is the code calling the parser.
public Document fileToDom(File file) throws ProcessException {
Document doc = null;
try {
DocumentBuilderFactory db = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = db.newDocumentBuilder();
if (this.errorHandler!=null){
builder.setErrorHandler(this.errorHandler);}
else {
builder.setErrorHandler(new DefaultHandler());
}
FileInputStream test= new FileInputStream(file);
doc = builder.parse(test);
...
} catch (Exception e) {...}
...
}
For the moment I find myself forced to remove the DOCTYPE before the parse, which removes all the problems, and the DTD validation... Not so great a solution.
Are you just using DocumentBuilder.parse(filename)?
If so, that's failing because it expects a URI. Open a FileInputStream to the file, and then pass that to DocumentBuilder.parse(InputStream).
Try this URI style:
file:///d:/folder/folder%20with%20space/file.xml
It looks like it's trying to connect to a URL in the doctype header so it can download it in order to validate the document against the downloaded DTD.
Try this.
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(test));
doc = builder.parse(is);
instead of just parsing the 'test'

I have the following ontology (https://raw.githubusercontent.com/wiki/ontop/ontop/attachments/Example_MovieOntology/movieontology.owl) stored in OWL File.
I tried to load it:
OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
File file = new File("movieontology.owl");
OWLOntology ontology = manager.loadOntologyFromOntologyDocument(file);
But I got this Exception:

If I try to load the ontology through a Web-based Visualization of Ontologies (WebVOWL), it loaded without any problems.
How can I solve?
Move to OWLAPI 4.2.3. Content negotiation has been upgraded and should handle any format the caller knows how to parse.
If this dies not work, please raise an issue in the OWLAPI tracker on github.

At first I thought may be server is not able to fetch External CSS. So I saved html string as html file and I am able to see the page on browser. That means server is able to access the CSS.
You may still be right about your CSS, since the fact that the main html has been saved does not mean that the CSS is well saved (actually, we don't even know if it tries to save it, have you tried to do your work through a proxy like Paros in order to know every communication you attempt?)
http://sourceforge.net/projects/paros/
By the way, your problem may be different. Are you behind a corporate proxy in your production environment? Does your "flying saucer pdf library" need any external resource (any .xsd or something like that) that could be stuck in the firewall and cause that time-out? Make sure that you have under controll all the communication your application generates and you will find your problem.
I'm trying to use PDFBox's PDFPagePanel to load PDF files into a Swing based eBook reader application.
PDDocument pdfDoc = PDDocument.load(file);
List<PDPage> pages = (List<PDPage>) pdfDoc.getDocumentCatalog().getAllPages();
PDFPagePanel panel = new PDFPagePanel();
panel.setPage(pages.get(0));
pdfDoc.close();
JFrame frame = new JFrame();
frame.add(panel);
frame.setVisible(true);
This in theory should work since the PDFPagePanel is just a JPanel and the file being opened appears to be read in properly as I can use the text stripper to extract text fine and get metadata. However whenever I run it, I get the following IndexOutOfBounds exception:

The page being put into the PDFPagePanel (pages.get(0)) definitely exists. I get the same error if I try using convertToImage() on a page as well. Any help is appreciated.
The problem is that pdfDoc was closed immediately after panel.setPage(). However, PDFPagePanel attempts to process the pdf stream only when the page is displayed. To overcome this exception make sure the document is available while it is still in use by PDFPagePanel. You may need to make the document a member variable since GC may collect it once the document leaves the scope which will trigger its closing.
I'm having an issue getting this to work. It takes in a string which consists of several pieces of information put together.
However, when I try to write the String to a file in order to track changes in the program over time, I receive an access is denied error:
void writeToFile(String input) throws Exception{
File file = new File("C:\\WeatherExports\\export.txt");
if(!file.exists()){
file.createNewFile();
}
BufferedWriter inFile = new BufferedWriter(new FileWriter(file,true));
try{
inFile.append(input);
inFile.newLine();
} catch(Exception e){
e.printStackTrace();
}
inFile.close();

Line 58:
BufferedWriter inFile = new BufferedWriter(new FileWriter(file,true));
You have to have folders created first. But you can't call file.mkdirs() - you need to call file.getParentFile().mkdirs() - otherwise, you will create a folder with the name of the file (which will then prevent you from creating a file with the same name).
I'll also mention that you should check the result code of mkdirs(), just in case it fails.
And though you didn't ask for it, I'll still mention that you don't need to call createNewFile() (your FileWriter will create it).
and, just for thoroughness, be sure to put your file.close() in a finally block, and throw your exception (don't just print it) - here you go:
void writeToFile(String input) throws IOException{
File file = new File("C:\\WeatherExports\\export.txt");
if (!file.getParentFile().mkdirs())
throw new IOException("Unable to create " + file.getParentFile());
BufferedWriter out = new BufferedWriter(new FileWriter(file,true));
try{
out.append(input);
out.newLine();
} finally {
out.close();
}
}
There's another possibility (just for anyone who may be reading this after the fact). I had the same problem, but all the parent folders existed. The problem turned out to be that there was a folder with the same name as the file I was trying to create.
On my case I was passing the directory where I should put the file I am generating.
I just appended the Filename to the directory and mine worked fine.
I am trying to stem a string using WordNet with the JWNL API. When I try to load the dictionary it gives me a FileNotFoundException.
This is the code initializing the dictionary:
public static void Initializer(){
try {
JWNL.initialize(new FileInputStream("file_properties.xml"));
dictionary = Dictionary.getInstance();
morphPro = dictionary.getMorphologicalProcessor();
}
catch(FileNotFoundException e){
e.printStackTrace();
} catch (JWNLException e) {
e.printStackTrace();
}
}
And this is what I get:

I am pretty sure that it has something to do with the path, but I can not find out exactly what is wrong, since I changed the file properties.xml to use C:\WordNet\2.1\dict\ - so that should be okay?
I also got the same problem.
The error was:

So I found the problem. In that properties.xml I given wrong path as:
<param name="dictionary_path" value="C:/Program Files/WordNet/"/>
So I changed its path to the directory contain verb file :
<param name="dictionary_path" value="C:/Program Files/WordNet/2.1/dict/"/>
So my problem solved.
Similarly you need to change the data.adj etc. to the form of adj.dat
(that is of course if you are not willing to change the version number in the file_properties.xml)
In file_properties.xml change the version number to the correct version.
Okay so I found out what was wrong. It was looking for the wrong files. I renamed the index.verb, index.adj etc. to verb.idx... This solved the problem and the program is now able to lookup the words in the dictionary.
jwnl doesn't work with wordnet 2.1 version. So try with wordnet 2.0
Then it works properly.
