Apologies if this has been asked already and I've missed it.
I'm writing a JavaFX desktop app, and would like to make it automatically run after installation, but I'm not sure where to look to make this happen (or even if it's possible?). I have successfully created a .dmg installer using E(fx)clipse & Ant. Are there options I'm overlooking which I can use in the build.xml? or am I looking in the wrong place entirely?
Thanks in advance :)

I am trying to download Eclipse onto my flash drive so that it can support itself if I try to use Eclipse on a computer that does not have a JDK/JRE installed and/or I do not have the permissions to install one.
I am able to download it onto the flash drive and run it fine, but the problem arises when I try to make it self-sufficient by downloading a JDK for Eclipse to use on the drive. I have tried many different solutions (yes, I am aware of the abundance of "why is eclipse telling me it cant find main class" questions), but none of them apply to me. I followed this tutorial in my endeavors, but when I run the batch file it comes up with the standard Failed to find a Main Class in "F:\eclipse\\plugins/org.eclipse.equinox.launcher_1.5.200.v20180922-1751.jar.
I know the \\ looks a bit out of place, but I know that's not the problem since I've tried editing the eclipse.ini file to fix the path but it gives the same error (just with F:\eclipse\plugins\org.[...].jar instead)
I'd really appreciate any help anyone could give. Thanks!
Eclipse has required Java 8 or newer since the Neon release, in 2016. Update your version of Java.
I have been using Eclipse for my Java needs for quite some time now, but I have never really delved deep into it.
I was recently given this project by a friend which makes use of the XText plugin library to act as an IDE for a custom file type.
However, to launch it, I need to open the source of the editor itself in Eclipse and run it as an Eclipse Application which in turns open a separate Eclipse IDE.
I have been looking around for an easy way around this, but to no avail. Is there a way to run said Eclipse Application without having to first open the source of the custom editor and launching it?
Thank you!
I solved it by creating a shortcut for Eclipse and adding -data "PATH_TO_APP" on the 'target' field.
Thank you for your help everyone. :)
I've been having trouble using NetBeans IDE 8.2 with JDK on Windows 7 64-bit. NetBeans can compile code, but doesn't run it. I've downloaded all of the necessary files and programs and even consulted with a computer programming teacher, but I haven't been able to work around this issue. The URL displays an image that shows what I get back after attempting to run a code.

JavaApplication1.java is still set as your main class.
To change your main class, go into Project Properties -> Run and change "Main Class" to TestClass.java.
Essentially, the compiler is still running whatever main function is found in JavaApplication1.java.
#notyou Also mentioned how you can right click a file and run it directly, instead of changing the project settings. I used to use this but it slipped me! This is super useful.
I'm pretty sure this question has some answers for you.
I am a new "programmer," and I've created a couple of very basic programs and so much of the terminology is very new to me. I wish to create an executable program from eclipse that I can use outside of eclipse and give a couple of other people for a project, and all of the tutorials said that I needed to use Java to create a .Jar program. The problem is that my version of Eclipse doesn't seem to have any options for working with Java. When I export, there is no option to export to Java. I have no option to create a new Java project either. I don't know the correct terminology, but it seems that my version of Eclipse is not connected to Java. Did I mess up somewhere along the line when installing Eclipse? Was there an option I failed to check? Any help would be appreciated! Thank you!
Hi i've been trying to install the library on Thinking in Java book 4th edition and i hit a very thick brick wall. I've done everything that the guide from the website told me to do and i still can't get the library to work. From what i've read it seems that the problem is from the build.xml files. having no xml knowledge I am clueless about how I have to modify it in order for it to work. In both cmd and eclipse I am getting these error
c:\TIJ4\code\build.xml
Build Failed
c:\TIJ4\code\build.xml:59:J2SE5 required
Can anyone tell me what I should do ?
I am using eclipse if there is a simpler solution by using eclipse rather than ant please help me out. It's been a week now and I still can't make it work.
The important thing to do is to realize that your ant file has a specific java requirement.
Something to try that might fix this very easily : I believe you can remove any references to a specific JDK, and if you have a reasonably up to date JDK, the build will succeed.
The definete fix : Look into the exact (line 59) of your build file, and try to satisfy the java version that line requires. Java is generally backwords compatible -- something designed to run in J2SE5 should run in the latest JDK. Its not terribly difficult to update your JDK (just google for instructions on your OS).
The most common mistake I see is that people who have the java run time installed believe they also have the Java SDK as well.
Does this "install the library" means you want to look at the code and run them in your eclipse? If so I can share my experience with you.
First run the Eclipse.py script; this will add package info to the source code
Create a new Java project in Eclipse, and then just copy all the source code folders to the src source folder in eclipse, these folders will then be recognized as Java packages.
You should be able to run the classes with a main function.
You can also configure which java version to use for this project in Eclipse build path. 1.5 or higher will work.
