I am trying to export an Eclipse plugin as a directory on Mac. I do the normal procedure where I export as Directory but I don't use the option to package as jar under Options. This works on Linux, but not on Mac; I always get a jar file. Is there a reason why is this happening?
I still haven't found the answer but the workaround is very simple; just use jar command to extract the jar content which is the same as export-as-directory content.

I have done a project in JavaFX. I used NetBeans IDE to do my project. I used MySQL as database. Currently I run my project with the help of NetBeans. Is there any way to make the project an executable file ?
What I meant by executable is to launch the project by double clicking on it. Suggest me some good and easy methods, with tutorial if possible.
What you are thinking of is a self-contained javafx application. Nifty guide here.
This is an .exe file (on windows, i tried it on kubuntu and it builds a nice .deb and a separate executable). You can place this executable somewhere else and it will work, even if no java is installed.
Netbeans has a folder for their projects. (Default: documents/NetbeansProjects)
There you will find your project.
First, click on the Clean and Build button inside netbeans.
Then you can find a .jar file in your project folder's dist folder.
You can use Launch4j to create executable file.

I just downloaded Eclipse Juno onto my machine. I extracted the files to an Eclipse subdirectory in "C:\Program Files". When I try to launch eclipse from here, it works great! But I don't want to have to navigate to this directory every time I want to launch eclipse. I tried just moving the executable to my Desktop, but then when I try to run it I get this message:
The eclipse executable launcher was unable to locate its companion library.
How do I let eclipse know where it's companion library is if I don't plan to have them in the same folder? Please be very specific.
Thanks!
You dont move the executable to your desktop because the executable needs to be in the same directory with other files where it was. get it back and then make a shortcut or link to it. you are free to make the shortcut or link where you want.
Well i had the same problem sometime back, and i figured out that since i've changed the location of my elcipse.exe , it has some how effected the "eclipse.ini " file
1.Path to -startup
D:\ < elcipse folder> elcipse:\ plugins\org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar \this is the start up jar file.
2.Path to shared lucher library
D:\ < elcipse folder> elcipse:\ org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813 \this is the shared launcher library jar file.
just set the follwing two paths and ti will start up again like befor..
Happy coding..
This is a bug filed with Eclipse for Windows and Mac:
When attempting to launch Eclipse (double click on Eclipse.app), the launch fails. The only action is a dialog box with this message:' the eclipse executable launcher was unable to locate its companion shared library'. I found an online description of the problem and the workaround here:
Specifically, as per the instructions above:
I opened the Eclipse.app package, located eclipse.ini, edited it
searched the plugins folder for something matching org.eclipse.equinox.launcher.carbon.
copied the maching folder name (from plugins)
pasted it as the terminating portion of the path for --launcher.library
replaced the --launcher.library line with that path

Eclipse Neon, 2017:
I copied my old .p2 folder found in my home.
Ran eclipse again and it worked.
It used to be that you could just copy eclipse as a zip and it would work fine, but it seems some plugins now rely on the .p2 folder.
If I export a plugin from Eclipse using the 'Export -> Deployable Plug-ins and Fragments' as a jar file. I was wondering how I can then use this plugin in my workspace after I restart Eclipse. Are there any additional steps I need to perform to use the plugin?
Just copy it into the dropins folder of Eclipse. Do not use the plugins folder directly as there is a good chance it won't be picked up.
Put the JAR in a folder named dropins/eclipse/plugins under your target eclipse directory.
An easier method to install it is to select 'install into host' when you export the plugin.
For testing purposes you shouldn't have to use the dropins folder, but instead launch it as an eclipse plugin.
Depending on the type of plugin you have created you may need to click a button or hotkey to activate it.
I have a netbeans project and I need to create an .exe file out of it.
I want it to run this program on a friends computer who doesn't have netbeans installed.
So how do I do this?
If its a java project then just compile and build the project. go to the project folder->dist folder, copy the .jar file and give it to your friend to use. ur friend needs to have JRE installed on his system.
I have eclipse and I can test run java apps but I am not sure how to compile them. I read that I should type javac -version into my cmd.exe and see if it is recognized. It is not. So I went to sun's website and downloaded/installed JDK v6. Yet it still says 'javac' is an unrecognized command. What am I doing wrong?
Thanks!
UPDATE
OK after reading some replies it seems like what I am trying to do is create a .jar file that can be ran on another computer (with the runtime). However I am having trouble figuring out how to do that. This might be because I am using Flex Builder(eclipse), but I added the ability to create java projects as well.
Thanks
UPDATE
OK I do not want to make a JAR file, I am not trying to archive it...the whole point of making a program is to send it to users so they can use the program...THAT is what I am trying to do...why is this so hard?
To setup Eclipse to use the JDK you must follow these steps.
1.Download the JDK
First you have to download the JDK from Suns site. (Make sure you download one of them that has the JDK)
2.Install JDK
Install it and it will save some files to your hard drive.
On a Windows machine this could be in c:\program files\java\jdk(version number)
3.Eclipse Preferences
Go to the Eclipse Preferences -> Java -> Installed JREs
4.Add the JDK
Click Add JRE and you only need to located the Home Directory. Click Browse... and go to where the JDK is installed on your system. The other fields will be populated for you after you locate the home directory.
5.You're done
Click Okay. If you want that JDK to be the default then put a Check Mark next to it in the Installed JRE's list.
You don't need a separate compiler, eclipse already compiles the application for you. What you probably want to do is to create an "executable" JAR file, which you can do in eclipse by selecting File->Export->Runnable JAR file.
Note, however, that the resulting JAR file is not a "real" (i.e. Windows binary) executable - it still needs a JRE installed on the target computer. There isn't really a way to create windows binaries; that's not how Java works. On the upside, it will work without recompilation on a Linux or MacOS machine (if it has a JRE installed).
javac is located in the "bin" folder of your JDK installation. In order to run it you must either use full path or add this directory to your systems search path via the Control Panel.
If you installed to c:\program files\java\jdk1.6.0 your call will have to look like this:
c:\> "c:\program files\java\jdk1.6.0\bin\javac" -version
Umm, eclipse is an IDE, it compiles things as you go. You don't need javac.
If you have Eclipse installed and you can write new java apps from within it, your compilation should work already..
Eclipse automatically builds/compiles your system when you're saving new Java files. Just try to write a new simple Hello world app, printing something to the console (just type sysout and Ctrl+Space inside Eclipse)
Eclipse automatically compiles all project in the workspace. YOu can disable this option if you like under Project->Build Automatically.
A JAR file can function as an executable, when you export your project as a JAR file in Eclipse (as Michael Borgwardt pointed out) you can specify what's the executable class, that meaning which one has the entry point [aka public static void main(String[] args)]
If the user installed the JRE he/she can double-click it and the application would be executed.
EDIT: For a detailed explanation of how this works, see the "How do I create executable Java program?"
