this is the line 57

the preivious code of screenshot an element in Login class works fine, so why this one have a problem ?
also the chromedriver not headless works fine but the headless not
Headless chrome default window size might be smaller than expected and this might cause your element to be outside of the window, hence not visible. You can either set the widndow size yourself or maximize window by using:
chromeOptions.addArguments(""--start-maximized")
i fixed the problem by adding
chromeOptions.addArguments("window-size=1980,960");

I am using Sikuli with Java to create a small automation tool. I am having trouble with this Unhandled Exception error. I am trying to pass a method I created to the GUI actionPerformed method.
package mission;
import org.sikuli.script.FindFailed;
import org.sikuli.script.Pattern;
import org.sikuli.script.Screen;
import tools.ChooseMission;
public class Story {
public static void runStoryMissions(int chapter, int stage) throws FindFailed, InterruptedException {
Screen screen = new Screen();
ChooseMission.ChooseChapter(screen,chapter);
ChooseMission.ChooseStage(screen, stage);
int dailyBiometricCount = ChooseMission.dailyBiometricCount(screen);
Pattern start = new Pattern("img/chapters/start.png");
Pattern replay = new Pattern("img/chapters/replay.png");
Pattern next = new Pattern("img/chapters/next.png");
Pattern mission_finish_bar = new Pattern("img/chapters/mission_finish_bar.png");
screen.click(start);
System.out.println("The mission has started.");
Thread.sleep(2000);
while (find(screen, mission_finish_bar) == false) {
System.out.println("Still playing the mission...");
}
if (screen.exists(mission_finish_bar) != null){
System.out.println("The mission has finished.");
}
System.out.println("Wait for 5 Seconds");
Thread.sleep(5000);
System.out.println("Click repeat button");
screen.click(replay);
}
Here is the code for my actionPerformed listener button:
btnStartMissions.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
int chapter = Integer.parseInt(txtFldChapter.getText());
int stage = Integer.parseInt(txtFldStage.getText());
System.out.println("Chapter #: " + chapter);
System.out.println("Stage #: " + stage);

} catch (FindFailed e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
There is a error at Story. runStoryMissions(chapter,stage) it says: Unhandled Exception type FindFailed and InterruptedException

Okay, I found the answer to my problem if anyone is interested.
Sikuli uses the java.awt features so scripts cannot implement and use Swing elements.
Java AWT Robot actions cannot be called froma Java swing container.
Solution is to create a new Thread:
new Thread(() -> {
try {
Story.runStoryMissions(chapter, stage);
} catch (FindFailed | InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}).start();
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!

Need to pass fileOutputStream while constructing the instance of ObjectOutputStream
objectOutputStream = new ObjectOutputStream(fileOutputStream);
on the line
objectOutputStream = new ObjectOutputStream(objectOutputStream);
You try to call the constructor with the objectOutputStream object, which is null. Looks like you meant to call it with fileOutputStream, like this:
objectOutputStream = new ObjectOutputStream(fileOutputStream);
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:

Browse button code:
#Override

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.

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