thanks for taking the time to read this. I'm fairly new to JavaFX and have a weird error in my compiler that I would like some insight on.
Here's the error:
2018-09-13 19:09:36.387 java[8040:660455] unrecognized type is 4294967295
2018-09-13 19:09:36.387 java[8040:660455] *** Assertion failure in -[NSEvent _initWithCGEvent:eventRef:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1652/AppKit.subproj/NSEvent.m:1969
Here is the code I am working with:
This is in a .java file named applicationSettings
public static double lookupUser(String name, String password) throws IOException {
InputStream inputStream = applicationSettings.class.getResourceAsStream("/files/users.xlsx");
XSSFWorkbook workbook = new XSSFWorkbook(inputStream);
XSSFSheet sheet = workbook.getSheetAt(0);
Integer lastRow = sheet.getPhysicalNumberOfRows();
int currentRow = 1;
while(currentRow < lastRow) {
if(sheet.getRow(currentRow).getCell(0).getStringCellValue().toLowerCase().equals(name.toLowerCase())) {
if(sheet.getRow(currentRow).getCell(1).getStringCellValue().toLowerCase().equals(password.toLowerCase())) {
double accessLevel = sheet.getRow(currentRow).getCell(2).getNumericCellValue();
System.out.println(accessLevel);
return accessLevel;
}
}
currentRow++;
}
return 4.0;
}
}
This is in a .java file named loginScreen
EventHandler<ActionEvent> loginClicked = new EventHandler<ActionEvent>() {
public void handle(ActionEvent event) {
double userFound = 0.0;
try {
userFound = applicationSettings.lookupUser(usernameField.getText(), passwordField.getText());
} catch (IOException e) {
e.printStackTrace();
}//END of Try/Catch
if(userFound == 1.0) { //1 is Admin Access
//TODO: Implement Login
System.out.println("Admin Login");
errorLabel.setVisible(false);
}else if(userFound == 2.0){ //2 is Elevated Access
//TODO: Elevated Access
System.out.println("Elevated Login");
errorLabel.setVisible(false);
}else if(userFound == 3.0){
//TODO: Basic Access
System.out.println("Basic Login");
errorLabel.setVisible(false);
}else{//Show Error
errorLabel.setVisible(true);
//TODO: Show Error
}//End If Statement
}
};
My Excel File is basically structured like this:
NAME PASSWORD ACCESS LEVEL
So for my login it would be like:

This isn't going anywhere besides by church where it's not really doing anything besides automating some tedious tasks, so security isn't an issue.
Also, if there's anyway I can clean up some of these if statements and my code in general I would appreciate any tips or help!
Edit 2 13.11.2018:
This bug has been officially fixed now in JavaFX 12, was backported to JDK8 and approved to be backported to JFX 11. You can have a look at the bug report to find more information about it.JDK-8211304 Here is a link to the changes they've made. openjfx I'm personally not sure about the current license situation of JDK8 so I would advise to switch to the newest OpenJDK and OpenJFX if possible.
Hey there I'm experiencing the same issue you have and I can constantly reproduce it. The issue appears for me on JavaFX on macOS 10.14. You can simply create an application with a button that opens a second stage. If you invoke stage.showAndWait() (could be related to anything that holds the thread) on the second stage and then switch focus between different applications (I just alt-tab between my JavaFX app and Safari), the JavaFX Application crashes. Also reproducible in any IDE.
I actually found a bug report on the OpenJDK/OpenJFX bug tracker but there isn't much going on at the moment. JDK-8211137 Mac: JVM Crash due to uncaught exception
I don't have a solution yet as I'm having troubles pinning down the exact problem but I found a workaround that works in my specific case.
Edit:
If I'm using "stage.show()" I'm only getting the error but when using stage.showAndWait() or anything that does some kind of waiting loop, the application completely crashes.

I am exporting a .jar file from a GUI built in Netbeans IDE. It works fine within Netbeans but once it is exported, some logic in the code does not execute properly.
I have tried debugging by running test cases displaying which items are passing through the if clauses. It seems to work well in IDE but not when it is run through .jar file.
for(Chamber chamber: chs)
{
if(!scheduledTools.containsKey(chamber))//unscheduled chambers
{
JOptionPane.showMessageDialog(this, chamber.getName()+": is unscheduled");
model.addElement(chamber.getName());
}
else//scheduled
{
if((scheduledTools.get(chamber).size()/range) > .25)
{
System.out.println("Range: " +range+" Scheduled: " +scheduledTools.get(chamber).size());
System.out.println("Cannot use this chambers:" +chamber.getName());
JOptionPane.showMessageDialog(this, chamber.getName()+": Cannot use this chamber");
}
else{
System.out.println("Scheduled but can use"+chamber.getName());
altModel.addElement(chamber.getName());
}
}
}
alternateChambers.setModel(altModel);alternateChambers.setSelectedIndex(0);
suggestedChambers.setModel(model);suggestedChambers.setSelectedIndex(0);
if(altModel.size()>1){JOptionPane.showMessageDialog(this, "Scheduled but can use these chambers:"+altModel);}
After making the necessary queries in seekDates method below:
private void seekDates(ResultSet rs) throws SQLException
{
ArrayList<String> entries;
//get how many dates we have so we can update progressbar
int results = 0;
setProgress(results);
if(rs.last()){results=rs.getRow();rs.beforeFirst();}
// processing returned data and printing into console
while(rs.next()) {
String scheduledChamber = rs.getString(2);
for(Chamber chamber : chambers){
//if the scheduled tool is a thermal chamber
//chambers get listed so far
if(!scheduledChamber.trim().toLowerCase().contains(chamber.getName().toLowerCase()))
{}//print chambers im not saving
else{
if(scheduledTools.containsKey(chamber))
{
//if key already used, just grab the list and add date
entries = scheduledTools.get(chamber);
entries.add(rs.getString(1).split(" ")[0]);
}
else
{
//if chamber hasnt been saved, add chamber and date
entries = new ArrayList<String>();
entries.add(rs.getString(1).split(" ")[0]);
scheduledTools.put(chamber, entries);
}
//System.out.println("Just saved this chamber:" +scheduledChamber+" with this date:" +scheduledTools.get(chamber));
}
;
}
publish(rs.getRow());
Thread.yield();
setProgress(100*(rs.getRow()/results));
}
}
The GUI should display the chambers found in the queries in one text field while displaying the rest of the chambers in another text field.
When I run this in the IDE. I get the correct outcome but once I compile using the package-for-store option in the build.xml file, the outcome then just lists all of the chambers in one text field.
In the .jar file, it seems that all of the chambers only satisfy the first if clause and none of the others.
Hi I am getting a strange error when I am running my JavaFX application from a JAR. When I attempt to use a drop area in my app that I added, I get a strange error. This is what I get when run from CMD (java.lang.reflect.InvocationTargetException). On the GUI the drop operation just gets stuck and doesn't complete.
I know that the code works, because when I run it from my IDE it works fine.
Any help would be great.
public void onDragDrop(DragEvent event){
files = new ArrayList<>();
Dragboard db = event.getDragboard();
boolean success = false;
if(db.hasFiles()){
//Do something with file.
List<File> temp_files = db.getFiles();
for(File f : temp_files){
if(FilenameUtils.getExtension(f.getPath()).equals("ovpn")){
files.add(f);
}
}
lbl_dragger.setText("Files Dropped: " + files.size());
success = true;
}
event.setDropCompleted(success);
event.consume();
}
UPDATE: Upon further testing, it seems that the error is actually coming from the line below:
if(FilenameUtils.getExtension(f.getPath()).equals("ovpn")){
files.add(f);
}
There seems to be some kind of error with the library I was using (ApacheCommons). As a workaround (unless this question gets an answer) using a simple (but less accurate) method will be suitable. See below if you too are stuck on this:
if(f.getAbsolutePath().contains(".ovpn")){
files.add(f);
}
Currently I have code that is used to change a password that is stored on an LDAP server. I am using a boolean variable to store the result if the update was successful or not, thereafter I check if the update failed via an if statement and I display an error message.
The issue I'm facing is how can I display more specific errors in the UI if the password change fails?
For example:
The existing password is invalid
The username is incorrect
The account has been locked
If someone could please advise on what could be a nice and tidy solution to my problem. Below is a snippet of the reset password method:
boolean passwordReset = this.userManagement.update(this.username, this.resetPassword, this.resetOldPassword);
if(!passwordReset){
super.addMessage(FacesMessage.SEVERITY_ERROR,super.getResource("password.error"), super.getResource("user.password.change.error"));
} else {
super.addMessage(FacesMessage.SEVERITY_INFO,super.getResource("change.password.head"), super.getResource("password.changed.success"));
}
I think you should modify the userManagement.update method to raise an exception in case of error. So depending on the error it could throw InvalidPasswordException, UsernameException, BlockedAccoutException, etc. or just throw an only exception with a custom message.
In any case, first you need to collect this information from the ldap operation.
Example code:
try {
this.userManagement.update(this.username, this.resetPassword, this.resetOldPassword);
} catch(InvalidPasswordException e) {
super.addMessage(FacesMessage.SEVERITY_ERROR, super.getResource("password.error"), super.getResource("user.password.change.error"));
} catch(UsernameException e) {
super.addMessage(FacesMessage.SEVERITY_ERROR, super.getResource("username.error"), super.getResource("user.name.error"));
} catch(BlockedAccoutException e) {
super.addMessage(FacesMessage.SEVERITY_ERROR, super.getResource("blockaccount.error"), super.getResource(blockaccount.error"));
}
Or:
try {
this.userManagement.update(this.username, this.resetPassword, this.resetOldPassword);
} catch(UpdateUserException e) {
super.addMessage(FacesMessage.SEVERITY_ERROR, super.getResource(e.getErrorCode()));
}
The problem with the first approach is that you have to create several (or a lot) of classes.
This doesn't happen with the second option, but you need a way to get the proper error message. You may add an error type/code to the exception.
Nearly 1 month my program worked fine, but today im getting the error above when starting it.
The error comes up in this line:
sounds.put(key, (Clip)AudioSystem.getLine(new Line.Info(Clip.class)));
I have no idea why.
After i read the accepted answer here, i reinstalled eclipse, deleted metadata and so on, but the error still comes up.
The code is to 100% right, but any way ill post the code near the error:
protected SoundArchive(String soundArchive, boolean debugFrame){
f = new File(this.getClass().getResource("../" + soundArchive).toString().substring(5)).listFiles();
sounds = new HashMap<String, Clip>();
try{
for(int i = 0; i < f.length; i++){
String key = f[i].toString().split("\\\\")[f[i].toString().split("\\\\").length - 1].split("\\.")[0];
sounds.put(key, (Clip)AudioSystem.getLine(new Line.Info(Clip.class)));
sounds.get(key).open(AudioSystem.getAudioInputStream(f[i]));
}
}
catch(Exception e){
e.printStackTrace(System.out);
}
if(debugFrame) debugFrame();
}
So, does anyone know what i have to do now? I've my back to the wall....
Busy trying to Call RPG function from Java and got this example from JamesA. But now I am having trouble, here is my code:
AS400 system = new AS400("MachineName");
ProgramCall program = new ProgramCall(system);
try
{
// Initialise the name of the program to run.
String programName = "/QSYS.LIB/LIBNAME.LIB/FUNNAME.PGM";
// Set up the 3 parameters.
ProgramParameter[] parameterList = new ProgramParameter[2];
// First parameter is to input a name.
AS400Text OperationsItemId = new AS400Text(20);
parameterList[0] = new ProgramParameter(OperationsItemId.toBytes("TestID"));
AS400Text CaseMarkingValue = new AS400Text(20);
parameterList[1] = new ProgramParameter(CaseMarkingValue.toBytes("TestData"));
// Set the program name and parameter list.
program.setProgram(programName, parameterList);
// Run the program.
if (program.run() != true)
{
// Report failure.
System.out.println("Program failed!");
// Show the messages.
AS400Message[] messagelist = program.getMessageList();
for (int i = 0; i < messagelist.length; ++i)
{
// Show each message.
System.out.println(messagelist[i]);
}
}
// Else no error, get output data.
else
{
AS400Text text = new AS400Text(50);
System.out.println(text.toObject(parameterList[1].getOutputData()));
System.out.println(text.toObject(parameterList[2].getOutputData()));
}
}
catch (Exception e)
{
//System.out.println("Program " + program.getProgram() + " issued an exception!");
e.printStackTrace();
}
// Done with the system.
system.disconnectAllServices();
The application Hangs at this lineif (program.run() != true), and I wait for about 10 minutes and then I terminate the application.
Any idea what I am doing wrong?
Edit
Here is the message on the job log:
Client request - run program QSYS/QWCRTVCA.
Client request - run program LIBNAME/FUNNAME.
File P6CASEL2 in library *LIBL not found or inline data file missing.
Error message CPF4101 appeared during OPEN.
Cannot resolve to object YOBPSSR. Type and Subtype X'0201' Authority
FUNNAME insert a row into table P6CASEPF through a view called P6CASEL2. P6CASEL2 is in a different library lets say LIBNAME2. Is there away to maybe set the JobDescription?
Are you sure FUNNAME.PGM is terminating and not hung with a MSGW? Check QSYSOPR for any messages.
Class ProgramCall:
NOTE: When the program runs within the host server job, the library list will be the initial library list specified in the job description in the user profile.
So I saw that my problem is that my library list is not setup, and for some reason, the user we are using, does not have a Job Description. So to over come this I added the following code before calling the program.run()
CommandCall command = new CommandCall(system);
command.run("ADDLIBLE LIB(LIBNAME)");
command.run("ADDLIBLE LIB(LIBNAME2)");
This simply add this LIBNAME, and LIBNAME2 to the user's library list.
Oh yes, the problem is Library list not set ... take a look at this discussion on Midrange.com, there are different work-around ...
