File copy access denied - java

Here I am trying to copy a file one location to another. I am having the source address as
F:\C#\Studies\OS\ch4.ppt
where I want to copy ch3.ppt to another location where user chooses .ie., fetching the destination address from the JFilechooser(Where ever the user wants to copy). Here I am getting access denied error
{
//Getting the value of fileLocationSourceDrive from table.
//fileLocationSourceDrive contains F:\C#\Studies\OS\ch4.ppt
JFileChooser location = new JFileChooser();
location.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
location.showSaveDialog(null);
String fileLocationDestination = location.getSelectedFile().getAbsolutePath().toString();
copyFile(fileLocationSourceDrive, fileLocationDestination);
}
public static void copyFile(String sourceFileName, String destionFileName) {
try {
System.out.println("Reading..." + sourceFileName);
File sourceFile = new File(sourceFileName);
File destinationFile = new File(destionFileName);
InputStream in = new FileInputStream(sourceFile);
JOptionPane.showMessageDialog(null, destinationFile);
OutputStream out = new FileOutputStream(destinationFile);
//OutputStream out = new FileOutputStream("C:\\Users\\Sagar Ch\\Documents\\New folder");
byte[] buffer = new byte[1024];
int length;
while ((length = in.read(buffer)) > 0) {
out.write(buffer, 0, length);
}
in.close();
out.close();
System.out.println("Copied: " + sourceFileName);
} catch (Exception ex) {
ex.printStackTrace();
}
}
Here the error block(Getting access denied)
Reading...F:\C#\Studies\OS\ch4.ppt

I believe that the problem is that you are trying to write the file (copy it, rather) onto the path of C:\Users\Sagar Ch\Documents\New folder, and that is not a "file", that's an existing folder. You should copy ch4.ppt to C:\Users\Sagar Ch\Documents\New folder\ch4.ppt.

How to upload RDF code to fuseki server using Java?

I wrote a function that convert data to RDF and I need to upload this RDF to the fuseki server.
I tried to implement the code from here as follows
public class GenerateRDF {
public void setRDF(String[] personalData ) {
String serviceURI = "http://localhost:3030/Date";
DatasetAccessorFactory factory = null;
DatasetAccessor accessor;
accessor = factory.createHTTP(serviceURI);
String name = personalData[0];
String nationality = personalData[1];
String date = personalData[2];
String address = personalData[3];
String mobile = personalData[4];
String email = personalData[5];
String website = personalData[6];
String profesional = personalData[7];
String education = personalData[8];
String communication = personalData[9];
String digital = personalData[10];
String professional = personalData[11];
String management = personalData[12];
String certifications = personalData[13];
InputStream in = null;
Model model = ModelFactory.createDefaultModel();
Resource node = model.createResource(personURI)
.addProperty(FOAF.name, name)
.addProperty(FOAF.member, nationality)
.addProperty(FOAF.birthday, date)
.addProperty(FOAF.homepage, address)
.addProperty(FOAF.phone, mobile)
.addProperty(FOAF.yahooChatID, email)
.addProperty(FOAF.weblog, website)
.addProperty(FOAF.plan, profesional)
.addProperty(FOAF.knows, education)
.addProperty(FOAF.depiction, communication)
.addProperty(FOAF.interest, digital)
.addProperty(FOAF.publications, professional)
.addProperty(FOAF.maker, management)
.addProperty(FOAF.made, certifications);
String base = "http://test-projects.com/";
model.read(in, base, "RDF/XML");
accessor.putModel(model);
model.write(System.out);
}
}
Which returns the following Exception:

Is there a way to fix this error? I'm open to solutions...
You might want to take a look here : https://hub.docker.com/r/stain/jena-fuseki/
There is a part on data loading that can guide you.
More specifically, load.sh and tdbloader that can be found here : https://github.com/stain/jena-docker/tree/master/jena-fuseki
I'm a bit puzzled by your question as you mention "upload a file to fuseki" in the tittle but your code does not refer to any file...

Save Word-file with Java (runnable JAR)

I´m trying to build an application which can read information from Excel files and place the data into a document. The document is a form of a template with columns in. Everything works just fine until the saving part.
It work, almost, like it should when I run the program directly in IntelliJ. However, when I install the application to an runnable JAR with Maven - the JAR won't work.
The file is saved as desired... But the new file contains nothing if I run the application from JAR. When i run directly in IntelliJ, the new file is been created and opened, but of 3 columns / row, only 2 has data in it.
What can I do?
Link to template document

Most probably you are missing libraries when it is exported as a JAR. You are using Apache POI as external libraries. Inside the IDE all the libraries were applied but when exported, they seems to be missing. Just run the jar file from command prompt to be 100% clear about the issue. In IDEs like NetBeans the libraries are exported into a separate folder called lib have a look for similar related to your IDE as well.

The problem is that many filenames have spaces or commas or things like that. What would be the best way to handle that? Have all input files pass through a character-escaping method?
I was looking at this and guess my problem is something similar:
http://sourceforge.net/p/saxon/discussion/94027/thread/b43bb749/
But that discussion is a little over my head.
UPDATE: I changed the constructors accordingly. Now I get this:

This is how I read the files:
protected static void openXMLChooser() {
setUIManager();
FileFilter filter = new FileNameExtensionFilter("XML files", "xml");
chooser = new JFileChooser();
chooser.setMultiSelectionEnabled(true);
chooser.addChoosableFileFilter(filter);
chooser.showOpenDialog(null);
if (chooser.getSelectedFile() != null
&& chooser.getSelectedFiles() != null)
infoarea.append("No file(s)\n");
}
And this is how I change the filename:
protected String[] fileName(String exten) {
file = chooser.getSelectedFiles();
pdffilename = new String[file .length];
for (int i = 0; i < file .length; i++) {
pdffilename[i] = file [i].getName();
b = new StringBuilder(pdffilename[i]);
b.replace(pdffilename[i].lastIndexOf("."),
pdffilename[i].lastIndexOf("l") + 1, "_result"+exten+"");
pdffilename[i] = b.toString();
}
return pdffilename;
}
And here I call the function:
XMLtoFO.xmlToFO(inputxsl, inputxml, this.fileName("fo.xml"));
Filenames are not URIs; you are using a filename where a URI is expected.
The simplest answer is to use the constructors for StreamSource that expect a File rather than a URI. So change
new StreamSource(X)
to
new StreamSource(new File(X))
because the "new File()" constructor works with file names. (Internally, the file name will be automatically converted to a URI, but you don't need to worry about that).

Opening a file produces a java.lang.NullPointerException

I have a JFrame and on the frame I have JButton, what I want is when that file is clicked that the user can load a file using the java JFileChooser.
I declare the FileChooser like this.
JFileChooser fc;
And then here is my code in the action listener for the button.
JButton btnLoad = new JButton("Load .txt");
btnLoad.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int returnVal = fc.showOpenDialog(OpenFile.this);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
//This is where a real application would open the file.
System.out.println("Opening: " + file.getName() + ".");
} else {
System.out.println("Open command cancelled by user.");
}
}
});
The error that it is producing me is

Here is line 73.
int returnVal = fc.showOpenDialog(Netflix.this);
Just declaring the JFileChooser variable is not enough, as you need to initialize the reference variable, fc, to a valid object first before using it. This is the same as for any other reference variable.
JFileChooser fc = new JFileChooser();
The value of fc is null. It needs to be set to that of an appropriate object before you call methods on it.

What's going wrong with this line ?
You need to assign player to an instance:
public static Player player = new Player();
