• Integrating JavaFX Scene Builder in the IDEs

  - by Jerome Cambon

  I experienced recently using Scene Builder from Netbeans, Eclipse and IntelliJ IDEA. As you may know, Scene Builder is a standalone tool, that can be used independently of any IDE. But it can be very convenient to use it with your favorite IDE, for instance start it by double-clicking on an FXML file, or run samples delivered with Scene Builder.  I'm sharing here with you few tweaks that I had to do for a better integration. Scene Builder 1.1 Developer Preview should be installed before doing the tweaks. The steps below have been done on Windows 7. It should be very similar on both Mac OS and Linux. Please tell me if you find any issue on one of these 2 platforms. Netbeans 7.3 Netbeans 7.3 can be downloaded from here. Creating a New FXML project Part of the JavaFx projects, Netbeans allows to create a 'JavaFX FXML Application', that creates a JavaFx project based on FXML description. The FXML file will be editable with Scene Builder. Starting Scene Builder from Netbeans If SceneBuilder 1.1 is installed, Netbeans will discover it automatically.In case of issue, one can open the Options panel, Java section, JavaFx tab. Scene Builder home should appear here. You can then either Open the FXML file with Scene Builder, or edit it with the Netbeans FXML editor : When 'Open' is selected, Scene Builder appears on top of the Netbeans window : When 'Edit' is selected, the FXML is opened in the Netbeans FXML editor, which support syntax highlighting and completion : Using Scene Builder Samples Scene Builder provides Netbeans projects, that can be opened/run directly : Eclipse 4.2.1 + e(fx)clipse 0.1.1 JavaFX integration in Eclipse has been done with the e(fx)clipse plugin. A distribution bundle containing Eclipse and e(fx)clipse is provided here. Creating New FXML project All the JavaFX-related projects can be found in 'Other' section : First create a new JavaFX project: Enter the project name (Test here). JavaFX delivery will be found in the JRE. Then, create a 'New FXML Document': Enter the FXML file name (Sample here). You may also want to choose the FXML document root element (AnchorPane by default). Dynamic root is for advanced users which want to manage custom types. Starting Scene Builder from Eclipse Once created, you can then either Open the FXML file with Scene Builder, or Open it in the Eclipse FXML editor : Using Scene Builder Samples from Eclipse To use Scene Builder samples, first create a new JavaFX Project (from 'Other' section): Then, on the next panel, 'Link additionnal source': … and select the source directory of a Scene Builder example : HelloWorld here (the parent directory of the java package should be selected).Then, choose a 'Folder name' for your sample: You can now run the Scene Builder example by right-clicking the Main.java source file: IntelliJ IDEA 11.1.3 IntelliJ IDEA Community Edition can be downloaded from here. IntelliJ IDEA has no specific JavaFX integration. Creating New IntelliJ project from existing source Since IntelliJ has no JavaFX project knowledge, we are using the Scene Builder samples as a starting point. We are going to create a new Java project from the HelloWorld sample: Then, click twice on 'Next' (nothing to change), then 'Finish'. The 'HelloWorld' project is created. Starting Scene Builder from IntelliJ We need to tell the IDE that FXML files are opened with an external application. Then, the OS file association will be used. To do this, open the File->Settings panel. Then, select 'File Types' and 'Files opened in associated applications'. And add a new wildcard : '*.fxml' : Now, from the HelloWorld project, you can double-click on HelloWorld.fxml : Scene Builder window appears on top of the IntelliJ window : Using Scene Builder Samples from IntelliJ We need to tell IntelliJ that the fxml files must be copied in the build directory.To do that, from the HelloWorld directory, open the 'idea' section, and edit the 'compiler.xml' file. We need to add an '*.fxml' entry: Then, you can run the sample from HelloWorld project, by right-clicking the Main class:

• Java IDE written in pure Java?

  - by Darestium

  Is there a Java IDE written in Java? I just got my year 9 DET laptop today at school, and there are all sorts of restrictions set in place. Somewhat annoyingly, you cannot run any executable other than the ones already installed on the system (for some reason they haven't disabled the use of Command Prompt, PowerShell, or strangely enough, regedit). They allow you to run Java executables, so I thought that would be the only way to be able to program on my crappy laptop at school (when I have finished all my work, naturally) :D Edit: By written in Java, I also mean that the executable, that is used to run the program, has the file extension ".jar", thus running on the JVM. Edit 2: I tried the DrJava IDE, and it worked great, thanks (I can compile and execute programs)! Regarding running Eclipse as through the command line using the command "java -jar "C:/Users.../org.eclipse..."". This results in an error producing a log saying file, the main error is: MESSAGE An error occurred while automatically activating bundle org.eclipse.ui.workbench (182). How do I fix this error (I much perfer working with Eclipse than any other IDE)? Edit 3: Regarding my last edit, just disregard it :D. I fixed the problem by downloading the latest version of Eclipse.

• Function inside .profile results in no log-in

  - by bioShark

  I've created a custom function in my .profile, and I've added right at the bottom, after my custom aliases : # custom functions function eclipse-gtk { cd ~/development/eclipse-juno ./eclipse_wb.sh & cd - } The function starts a custom version of my eclipse. After I've added it, because I didn't wanted to log-out/log-in, I've reloaded my profile with the command: . ~/.profile and then I've tested my function by calling eclipse-gtk and it worked without any issue. Today when I booted, I couldn't log in. After providing my password, in a few seconds I was back at the log-in screen. Dropping to command line using CTR + ALT + F1, I've commented out the function in my .profile and the log-in was possible without any issue. My question is, what did I do wrong when I wrote the function? And if there is something wrong, why did it work yesterday after reloading the profile. Thanks in advance. Using: Ubuntu 12.04

• How can I remove a Unity window entry?

  - by Pol Delgado Martin

  I installed Eclipse long time ago from the Software Center, but recently I needed a newer version than the repo one. Then I removed it via Software Center and installed Eclipse Kepler in /opt. However, the window opened is not called Eclipse, it is the name of an old program I made (Eclipse- GMM). However, that's not the main issue, but that even if I created a .desktop file it launches the same, having "two" eclipses in the dock, the actual program and the launcher. How can I remove Unity .desktop cache or wathever it is this?

• A class meant for an alfresco behavior and its bean, how do they work and how are they deployed trough eclipse

  - by MrHappy

  (This is a partial repost of a question asked 10 days ago because only 1 part was answered(not included), I've rewritten it into a way better question and added 3 more tags) where do I put the DeleteAsset.class or why isn't it being found? I've put the compiled class from the bin of the workspace of eclipse into alfresco-4.2.c/tomcat/webapps/alfresco/WEB-INF/classes/com/openerp/behavior/ and right now it's giving me Error loading class [com.openerp.behavior.DeleteAsset] for bean with name 'deletionBehavior' defined in URL [file:/home/openerp/alfresco-4.2.c/tomcat/shared/classes/alfresco/extension/cust??om-web-context.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: com/openerp/behavior/DeleteAsset (wrong name: DeleteAsset) when I put it in there.

• Accessing a file in Windows and Linux when working with JAVA+Eclipse.

  - by Gabriel A. Zorrilla

  Hi there. I'm doing some JAVA coding at home and at work. At home i have Linux, work, Windows. The rootpath to X file in Windows is c:\Documents And Settings\User\My Documents\Dropbox\file.xxx and in Linux is something like /media/My Documents/Dropbox/file.xxx So, every time i edit in either system, i have to manually change the root of the file in a new File(FILEPATH) statement. Is there a workaround for this? I bet if the file root is relative to the project resource tree would do the trick, but that's an Eclipse based solution, not JAVA, i believe.

• SWT: problems with clicking button after using setEnabled() on Linux

  - by Laimoncijus

  Hi, I have a strange case with SWT and Button after using setEnabled() - seems if I disable and enable button at least once - I cannot properly click with mouse on it anymore... Already minify code to very basic: import org.eclipse.swt.SWT; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.events.SelectionListener; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class TestButton { public TestButton() { Display display = new Display(); Shell shell = new Shell(display); GridLayout mainLayout = new GridLayout(); shell.setLayout(mainLayout); shell.setSize(100, 100); Button testButton = new Button(shell, SWT.PUSH); testButton.addSelectionListener(new TestClickListener()); testButton.setText("Click me!"); //testButton.setEnabled(false); //testButton.setEnabled(true); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } class TestClickListener implements SelectionListener { @Override public void widgetDefaultSelected(SelectionEvent e) { } @Override public void widgetSelected(SelectionEvent e) { System.out.println("Click!"); } } public static void main(String[] args) { new TestButton(); } } When I keep these 2 lines commented out - I can properly click on a button and always get "Click!" logged, but if I uncomment them - then I can't click on button properly with mouse anymore - button visually seems to be clicked, but nothing is logged... Am I doing something wrong here? Or maybe it's some kind of bug on Linux platform? Because on Mac running the same code I never experienced such problems... Thanks for any hint! P.S. Running code on Ubuntu 9.10, Gnome + Compiz, Sun Java 1.6.0.16

• How to use pom.xml/Maven to initialize a local thoughtsite (App Engine sample) project in Eclipse?

  - by ovr

  This sample app ("thoughtsite") for App Engine contains a pom.xml in its trunk: http://code.google.com/p/thoughtsite/source/browse/#svn/trunk But I don't know what command to run in Maven to set up the project locally. (The README doesn't mention anything about Maven.) I tried to just import the project code directly into Eclipse but it doesn't look like it's in an appropriate format for a direct import. So I assume I need to do something with Maven to get it set up correctly. I haven't really used Maven before so I'm not sure what command I would need to run to set everything up. The pom.xml seems like it downloads a bunch of dependencies for the project like the Spring jar files which I don't see anywhere else in the svn repository.

• How to avoid Eclipse warnings when using legacy code without generics?

  - by Paul Crowley

  I'm using JSON.simple to generate JSON output from Java. But every time I call jsonobj.put("this", "that"), I see a warning in Eclipse: Type safety: The method put(Object, Object) belongs to the raw type HashMap. References to generic type HashMap should be parameterized The clean fix would be if JSONObject were genericized, but since it isn't, I can't add any generic type parameters to fix this. I'd like to switch off as few warnings as possible, so adding "@SuppressWarnings("unchecked")" to lots of methods is unappealing, but do I have any other option besides putting up with the warnings?

  This confuses me. The following compiles fine under Eclipse. package com.example.gotchas; public class GenericHelper1 { static <T> T fail() throws UnsupportedOperationException { throw new UnsupportedOperationException(); } /** * just calls fail() * @return something maybe */ public boolean argh() { return fail(); } public static void main(String[] args) { // TODO Auto-generated method stub } } But if I try to do a clean build with ant, or at the command line with javac, I get this: src\com\example\gotchas\GenericHelper1.java:14: type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds boolean,java.lang.Object public boolean argh() { return fail(); } ^ 1 error what gives, and how do I fix it?

  I am almost done with one Java project that I have been developing on Linux. Now I need to build and test it on Windows. So I have installed Eclipse on Windows XP 32-bit, and imported my project.

• Java program runs smoothly in Netbeans but slowly in Eclipse and as an executed jar. WTF?

  - by comp sci balla

  A java program that does frequent swing/awt painting animation (but nothing more advanced than g.fillOval(...)) runs at a consistent 60fps in Netbeans, and at about 6fps when ran in Eclipse or executed as a jar file from a unix terminal. The program was developed in Netbeans and is run-of-the-mill desktop application (not webstart or japplet or ...). This is occurring in Ubuntu 10 with java 1.6. How is this possible? The universe no longer makes sense to me.

  Hy! I have my project with pydev and looks like this: ProjectName -src -gaesessions -geo -static_files -app is this ok? I really don't like to have the gaesessions and geo in my root, but their namespace are by root. I would like to have a structure like this: ProjectName -src -python -thirdParty -gaesessions -geo -app -static_files is this possible? or even better would be to make them as a library. this would be the best thing, but how to do this in eclipse and then when deploy my app, to deploy with those files too? thanks

• Why are button sizes on Eclipse vs Device not the same.

  - by Mike Droid

  O.k....this is weird. I had my buttons looking fine last week, now something has changed. My buttons on the eclipse emulator are much larger than on my device (Droid 2.1). I checked my skin settings, screen size permissions, density factors....what am I missing? My skin is set to WVGA854, but when the app goes to the phone the buttons are smaller!? Text and pictures are fine...looking the same as the emulator...just the buttons are shrunk! Hmm....I know it has to be something simple...:)

• are there java based auto-updating tools other than WebStart & Eclipse P2?

  - by DaddyB

  Hi, I am working on a java based application and we are looking to ease our deployment of updates. Up until now, we've always simply sent out new install packs & had the sysadmin's on our customer sites roll out the upgrades - painful for a large number of users. what I'd like to do is something similar to java webstart (or eclipse p2) - when the application starts, it checks for updates in a specified location and then downloads the updates prior to starting. But here's my problem - I want more control over what's done outside of the scope of plugins & jar files. For example: I'd like to be able to upate my JVM (we ship a modified version with additional security features). I need to install DLL's - possibly local to the jar files, sometimes to windows Occasiontally run MSI's to install windows components (e.g. printer drivers). I need to modify config files & the registry. I have found a few applications that support this (such as AppLifeUpdate at http://www.kineticjump.com/) but they tend to be .NET focused and it seems a bit perverse to introduce a .NET dependancy on a java application ;) I know I could write my own here, but if there is already a 3rd party library out there that supports this kind of facility, then it would make my life a lot easier. So, has anyone else had a similar problem & knows of some products I could look at? Thanks, Brian.

• How do you fix issues with the debugger for the Android plug-in for Eclipse not attaching?

  - by user279112

  I have been trying to program something for the Android mobile phone, using Eclipse and the Android plug-in for that IDE, and my debugger used to attach just fine. But then it has suddenly started having consistent issues attaching. I just get that message about how the process is waiting for the debugger attach, and then it just won't. What determines whether the attachment glitches so seems to have something to do with what the code is that I'm trying to debug, as it seems to be drastically more of an issue with some versions of my code than with others (on the same app). How do I fix this? Now before you answer, please understand that I have researched this issue already. I have found a couple of solutions that have worked with other people, but which do not work for me. One of which is setting the debuggable property in the main manifest file as true, and the other is going into Dev Tools and into some settings menu, and from there selecting the process and essentially saying to the fake phone, "Debug this process". Neither has really worked. Any other ideas? And just in case...I've run into one blasted technical issue like this after another trying to program for that stupid phone. And I'm not the only one who's having these issues; when I go online to research these issues, it is always very easy for me to find many people who have the same issues, and who are having to use the shottiest, sloppiest, most "ghetto" solutions to work around these issues. I know that many people have created good applications for that phone, but I don't see how I'm supposed to do that when the SDK and the plug-in just don't work half the time. Does anybody know how I may put all this trash behind me, once and for all? Thanks for your answers to either question!

• Why does Eclipse skip lines when I debug JBoss?

  - by ZeKoU

  Hi, I am trying to debug web service call which uses JMS in the background.I have JBoss running in debug mode. What happens is that when I press F6 in Eclipse (to execute current line) it skips certain lines. I have this method: @Override public void log(MsgPayload payload) { 1 Date startTime = new Date(); logger.info("Publishing with BufferedPublisher.java start time:"+startTime); 3 publisher.send(payload); Date endTime = new Date(); logger.info("Publishing with BufferedPublisher.java end time:"+endTime); long mills = endTime.getTime()-endTime.getTime(); double secs = mills/1000.0; logger.info("Publishing with BufferedPublisher.java total time (seconds):"+secs); } So what happens? I have breakpoint at line 1. When I press F6 it skips that line and goes to line 3. When I press F6 again it goes to the end of the method. Half of the code is never executed..??? My question is why. I am assuming my source is not well attached to the real code that is being executed.But how do I change this? Thanks.

store an invoice with a list of items through my app. In the development console I can see that items are not persisted to any field while the rest of the invoice class properties are stored properly. Does anyone know what I am doing wrong? Solution As pointed in the answers, the error says that the InvoiceItem class was missing a primaryKey. I tried with: @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Long id; But I was getting javax.jdo.JDOFatalUserException: Error in meta-data for InvoiceItem.id: Cannot have a java.lang.Long primary key and be a child object (owning field is Invoice.items). In persist list of objets, @aldrin pointed that For child classes the primary key has to be a com.google.appengine.api.datastore.Key value (or encoded as a string) see So, I tried with Key. It worked. @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id;

  I just started a new project and my boss wants us to change IDE from NetBeans to Eclipse, RichFaces to Flex. I have never worked with Eclipse and Flex before.

• Bash completion for Maven escapes colon

  - by armandino

  I added bash completion for Maven following the docs: http://maven.apache.org/guides/mini/guide-bash-m2-completion.html Everything works well except for goals that use a colon. For instance, instead of mvn eclipse:eclipse completion escapes the colon mvn eclipse\:eclipse Any suggestions how this can be fixed? I'm using Ubuntu 8.10 (2.6.27-17-generic) and $ bash -version GNU bash, version 3.2.39(1)-release (i486-pc-linux-gnu)

• Intel graphics driver installer, now the CPU fan is rarely quiet

  - by Space monkey

  I have an Optimus chipset: Intel HD 4000 (i7-3635QM CPU) Geforce 640m I don't care about the NVIDIA card, so I didn't try to install any proprietary drivers for it. So: I was having a choppy+high CPU experience with gnome-shell on Ubuntu 14.04. Only happened when I tried moving a window around quickly. I used the Intel graphics installer hoping that it will fix the problem. It did fix the problem, now there is no choppyness or high CPU when I move windows around. However, there is a new problem now: The fan is rarely quiet, doing barely anything at all will cause the fan to go into loud mode quickly. That happens despite the CPU usage being at just around 4%. This wasn't the case before installing Intel drivers. It would normally only do that if, for example, I'm installing packages or doing something that puts some stress on the CPU. I set all CPU cores to "powersave" using cpufreq-set, but nothing changed. Also on Windows, the fans are really quiet when I'm in powersave mode. I believe they completely shut off for most of the time. I remember the installer giving me a report at the end as to which packages it installed. Unfortunately, I didn't save the report and I don't know where it would have saved it if it did. Any ideas or similar experiences?
