The UI has two buttons, browse and submit. I want the user to hit browse to find a file, and then submit to copy it to a different location. However whenever I attempt it, I get this stack trace:

"Submit" button actionPerformed :
#Override
public void actionPerformed(ActionEvent arg0) {
if (mod.exists()) { //line 154 mod is a file object
OS = System.getProperty("os.name").toLowerCase();
detectOS();
modLocation = new File(fullPath);
if (modLocation.exists() && modLocation.isDirectory()) {
Path newP = modLocation.toPath();
Path oldP = mod.toPath();
try {
Files.copy(oldP, newP);
} catch (IOException e) {
e.printStackTrace();
}
JOptionPane.showMessageDialog(frame, "Mod successfully copied to: "
+ fullPath);
System.out.println("Mod successfully copied to: " + fullPath);
}
}
}
Browse button code:
#Override
public void actionPerformed(ActionEvent arg0) {
final JFileChooser fc = new JFileChooser(homePath + "\\Downloads");
FileNameExtensionFilter filter = new FileNameExtensionFilter("ZIP & JAR Files",
"zip", "jar");
fc.setFileFilter(filter);
int returnVal = fc.showOpenDialog(frame);
if (returnVal == JFileChooser.APPROVE_OPTION) {
final File mod = fc.getSelectedFile();
textField.setText(mod.getAbsolutePath());
System.out.println("File: " + mod.getName());
} else {
System.out.println("Open command cancelled by user.");
}
System.out.println(returnVal);
}
I basically want the variable mod to carry on to the Submit area, but because of where it is set, I am unable to do so.
In your "browse" button code you are initializing a local variable mod like this:
final File mod = fc.getSelectedFile();
In the "Submit" button code you are using a class variable mod. Same name, different variables with different scopes.
Try changing:
final File mod = fc.getSelectedFile();
to
mod = fc.getSelectedFile();
with mod being a private class variable.
Also add null check in the "Submit" button code.

I am getting the following error while running this code. I found that it happens because of the merger.mergesPagesFromPdfFiles() function. How can i prevent this to happen? I tried several things but nothing worked.
java.nio.file.FileSystemException: C:\Users\Ben\Desktop\Post\Klanten\10817 - TEST TEST\Factuur TEST TEST.pdf: (Translated) The process does not have access because the file is used by another process
Merger merger = new Merger();
merger.mergesPagesFromPdfFiles(filesToSend, getPathPostTS().toString() + "\\"
+ CustomFunctions.generatePersonalFileName("Documenten", client) + ".pdf");
//Runtime.getRuntime().gc();
//merger = null;
for (String file : filesToSend) {
File fileEntry = new File(file);
try {
fileEntry.setWritable(true);
java.nio.file.Files.deleteIfExists(fileEntry.toPath());
//Another way of trying to delete it
if (fileEntry.delete()) {
System.out.println(fileEntry.getName() + " is deleted!");
} else {
System.out.println("Delete operation is failed.");
}
} catch (Exception e) {
e.printStackTrace();
}
}
System.out.println(folder.list());
if (folder.list().length > 0) {
folder.delete();
} else {
JOptionPane.showMessageDialog(null, "FOLDER IS NIET LEEG, KIJK NA");
}
And here is the merger class creating the conflict.
public Merger() {
}
public void mergesPagesFromPdfFiles(List<String> pdfFiles, String outputFileLocation) {
try {
Document document = new Document();
FileOutputStream fos = new FileOutputStream(outputFileLocation);
PdfCopy writer = new PdfCopy(document,fos );
writer.setMergeFields();
document.open();
for (String pdf : pdfFiles) {
int index = pdf.lastIndexOf("\\");
String pdfName = pdf.substring(index + 1, pdf.indexOf(".pdf"));
PdfReader reader = new PdfReader(pdf);
// if(reader.getNumberOfPages() < mergePageNr){
// System.err.println("'" + pdfName + "' has not enough pages to
// merge. Skipped to next pdf!");
// continue;
// }
writer.addDocument(reader);
}
System.out.println("Files merged!");
document.close();
writer.close();
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Thanks for helping out!
edit: complete error plus changed code to close fos
Files merged!

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.
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

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.

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).
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.
