I am using version 1.9.0 of the REDHAWK IDE on CentOS 6.5 and ran software updates today, made up of OpenJDK updates.
Before the updates, I was able to see the sandbox and chalkboard in the IDE. When I opened the IDE a little while after the updates, the sandbox was gone.
I tried installing Java SE JRE version 1.8.0_05 and restarting REDHAWK IDE without success.
I then tried a fresh IDE installation, which successfully showed the sandbox for two different times starting the IDE. Although, after being closed for an hour or so, the sandbox went missing again.
Does this sound like a java issue? If not, is the IDE breaking itself in some way?
Note that during the time of REDHAWK inactivity I was only using a word processor and a web browser.
Edit: Prior to the updates I had installed the newest GNU HAWK components and was able to load various GNU HAWK components onto the chalkboard with the sandbox still showing up.
I had the same issue, and ended up fixing it by commenting out the following line in the eclipse.ini file:
#-Dorg.omg.CORBA.ORBClass=org.jacorb.orb.ORB
For other people looking at this, I went through the basic example in the Getting Started and the plot window would flash and go away. It is related to that line in the accepted answer.

I've installed Pydev plugin with eclipse c/c++ and it worked will but after two days something wrong happened and it shows this message
(No editor descriptor for id org.python.pydev.editor.PythonEditor)
I tried to install it once again but still the same problem
That message means that PyDev isn't really properly installed or its requisites are not properly matched.
The possible reasons are that you're using a different java vm from the one you had (PyDev requires java 8 onwards), it became corrupted (i.e.: could happen if you had some issue in your hard drive, but that's very rare compared with not running Eclipse using java 8) or you're using an older version of Eclipse with a newer version of PyDev (see the "Need to use older Eclipse/Java" section on http://www.pydev.org/download.html).
I am very experienced with eclipse, using it since its Juno days, but today i have ran into one of the strangest bugs and want to know if any of you have had this bug and if you may have an answer as to how to fix it. (Or at least a work-around to getting my favorite IDE working again).
I recently updated to Ubuntu 16.04 (Xenial) and it seems nothing wants to work like it did when i had Wiley, namely eclipse. I used the installer to download the IDE and launched it and i got a strange issue where the IDE would load and ask for a workspace, but would then show a dialog box that is using the screen buffer as its data.
Screenshot with strange eclipse launch
I then thought that it may be an issue with the downloaded file (Corruption or something) so i downloaded the tar from eclipse.org directly. I extracted the tar and launched the eclipse executable and it loaded up and asked for a workspace again and began to launch, and finally it came up, the same old back buffered box.
So i got the idea to run it from the console and got this output, but i have no idea what it means. I saw no stack traces so im sure its fine (Again it may be a GTK error, so any ubuntu people this is where you come in)
Console Run with the same problem
I started to think it was my java version (Oracle JDK 9 for Linux)that was the problem so i did a test compile of the hello world program and everything was fine, it all worked.
(Would add screen shots but im new here so i dont have enough reputation to do so :( )
Any idea what it might be? Any help would be great!
I found the problem, i installed the latest version of java in the apt repository. This version was JDK9 which Eclipse does not support (At least not until Eclipse Oxygen). I purged the computerof JDK9 and installed JDK8 and everything worked fine!
Moral of the story, don't use JDK9 on Neon
I am running a dual boot windows 10 and Ubuntu 16.04, I have similar issue where I can see all the file menu and the eclipse launched on the tool bar, I have selected the application and used ctrl+WindowsKey+left,right to split the application to half of my screen and then magically it appeared,Then I adjusted to fit to my screen.
Would a fresh install work? I didn't have any issues. Perhaps ask this on ask ubuntu, too.
im running a linux box with gtk3 and was re-installing my STS today.
I was choosing the x64 version based on eclipse 4.6 and everything went fine after starting the new installed STS version.
Then i decided to check for updates and was installing the suggested packages (i didnt install any own custom packages/plugins yet).
After the restart the GUI seems to be broken. Please see the Screenhot: http://imgur.com/0lAtByT
Im working already since some years with STS on Linux but never found this strange behavior. Anyone a idea what could fix this problem?
Try:
-Dswt.enable.autoScale=false
when starting STS.
Every time go to run the Linux Version of Eclipse Luna SR2, it just stops at the little Splash Screen (The window that comes up before you select your work space) and it just stays like that for about 30 seconds, and then closes. Any help please?
It generates this error log which is found Here
New Answer: This is a known bug and a workaround that has fixed the issue in at least one case is to run
export SWT_GTK3=0
before starting Eclipse. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=430736 for more information. If this workaround does not fix your issue make sure GTK3 is installed and upgrade glibc to at least version 2.14 to ensure Eclipse uses it. Apparently when Eclipse detects an older glibc it tries to use GTK2. If none of these suggestions fix your issue you should submit a bug report at http://bugreport.java.com/bugreport/crash.jsp to work it out with the Eclipse development team and also to help inform other people about it.
#ElectroMan - This got too long for a comment. Yes, the error log says the same thing. That means you are running Java 6, "JRE version: 6.0_34-b34" according to the log. I suggest you try running Java 8 or at least Java 7. Java SE 8u40 is the current release from Oracle and it can be downloaded for 64 bit Linux from a link on http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html. It is best to use the latest Oracle release and get away from the OpenJDK version, especially one that is two major releases outdated. However, if you opt for Java 7 its final release is available at http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html. You should be able to install either in a non-default location and keep OpenJDK 1.6.0_34 as your main version of Java on your platform. Eclipse can be configured to use Java 8 or 7 after it is installed by project or as its default for all new projects, but the main thing is to tell it to use Java 8 or 7 when it runs, since it is a Java application. Some instructions for this are at http://www.cs.umd.edu/eclipse/install_java8_luna.html. One of the main reasons for upgrading from Eclipse Kepler to Luna is to get built-in Java 8 support. Another option is to follow the instructions in the error log and file a bug report at http://www.cs.umd.edu/eclipse/install_java8_luna.html and wait for a reply. Or maybe there is already a new Luna update and you could try it.
I have installed the Netbeans 6.7 IDE with Java ME included, but cannot create a Mobile Application project from the Java ME category. When I select the project type the wizard stops at "Finding Feature" with the message:
Not all requested modules can be enabled:
[StandardModule:org.netbeans.modules.mobility.end2end.kig jarFile:C:\Program Files\NetBeans 6.7\mobility8\modules\org-netbeans-modules-mobility-end2end-kit.jar.
I am attempting to run this on Vista Home Premium. I have tried to run the IDE as Administrator with no luck.
I am at a loss for where to go next as I cannot seem to find any information regarding this issue. Even if you don't have the solution any insight into this error message would be helpful.
I am unable so far to get the project running via the Netbeans IDE install. I have, for the time being, installed the Java ME SDK which includes a very stripped down version of the Netbeans IDE for mobile development.
I originally had some issues starting the SDK as well on Vista. The IDE reported that it could not connect to the device manager on localhost. After some searching I found this link: Java ME SDK Startup Problem which suggests changing the hosts file localhost entry from IPv6 to IPv4. The fix worked perfectly and I can now compile and run code in the emulator.
This is not an optimal solution as the SDK does not include the visual design tools, however I am able to get a basic project going in the mean time.
I have given up on the 6.7 version and have instead located and installed 6.5.1. This previous version has been working just fine and seems to do everything I need.
I ran into the exact same error today while installing NB 6.8 beta. To resolve it we need to install two plugins:
Java Web Applications (as mentioned by Ali above) and
Sun Java System Web Server 7.0
Note that these two are part of the Category called "Java Web and EE" hence the confusion that we need to install Glassfish App Server. But we need these two plugins because they are required for debugging using breakpoints in emulator. Netbeans runs a web server when we do breakpoint based debugging.
Also note that the Java Web applications needs SOAP Web Services and JavaScript Debugger plugins to run and so these plugins are also installed when you try to install it.
You also need to install "Java Web Applications" plugin.

If the module is present, you should try unzipping it to check its content makes sense.
You should also be able to rebuild it from Netbeans sources.
You can also try to figure out why this happens by debugging the module loader inside Netbeans from its sources, using another IDE, presumably the latest version of Netbeans you can find without the issue.
If the module is missing, you might want to get the missing jar file from an installation of a previous version of Netbeans, see if it is compatible.
6.5.1 isn't missing any module.
back in version 5.5, the mobility module had to be downloaded and installed separately from the main IDE.
If you want to consider using Eclipse for developing your J2ME app...I've written a post related to that some time ago: here.
