Java dropbox GUI

I should highlight also that I'm not trying to focus on the GUI question I am having success with that portion its just simply this bit of code hanging me up...

public void uploadFile() throws FileNotFoundException, DbxException, IOException{

fc = new JFileChooser();
fc.setMultiSelectionEnabled(true);
//fc.setFileSelectionMode();

int dialog = fc.showSaveDialog(this);

if (dialog == JFileChooser.APPROVE_OPTION) {

inputFile = fc.getSelectedFile();
inputFile.getAbsoluteFile();

try{
FileInputStream inputStream = new FileInputStream(inputFile);
// this is where its not uploading all the code above is running fine

uploadedFile = client.uploadFile(homeDir,
DbxWriteMode.add(), inputFile.length(), inputStream);
String sharedUrl = client.createShareableUrl(homeDir);
System.out.println("Uploaded: " + uploadedFile.toString() + " URL " + sharedUrl);
} catch (IOException e){
}
