I've noticed that a JNI error occurs in some environments. When that error happens, pls try to copy your jdk (usually in C:\Program Files\Java) instead of jre and also change the exe path accordingly. Sorry for the trouble!
If your image or other resources don't show up in the exported program, please check if you have specified your resources correctly in your code. Absolute address such as ".//res//image.jpg" doesn't work in exported programs (either jar or exe). If you are not sure how to specify resources, check this video that I made a while ago: th-cam.com/video/d02PK8C5EaA/w-d-xo.html
Thank you so much.by the way if your project is a console only,then you need choose Header Type:Console at Header-->Header Type.otherwise the exe can't to run.
Has anyone had the same problem and does anyone know how to solve? The JRE tab on Launch4j is a bit different and I don't know what am I doing wrong. I used JDK version 20.0.1 and when I try to create the .exe file it does so, but it doesn't run whatsoever, while it was running as a .Jar file. Thank you in advance guys.
hi, today I tried this for the first time... and after several errors I finally ran it. I used lib and bin folder from jdk-17. In JRE settings in launch4j(v. 3.50) i checked "JDK required" (min. JRE version 1.6.0). with these settings i am able to run it on different PCs.
Hi how do I get the .exe to run on the other device if I had to add JVM Options, I added the libraries etc. to the same file and changed the paths to use the one's in the folder. By doing this it runs on my device but not on another device.
I am getting [Error: A JNI error has occurred, please check your installation and try again] from the JVM launcher and after that another error: [A Java Exception has occured]. Has anyone had a similar issue or have any hints? Any help is appreciated! For context: my .jar file works perfectly fine, I have version 1.8.0 JRE and I use image and wav resources in my jar file.
@@sparkfire22223 I have not found an answer yet unfortunately. My understanding is that with bundled JRE and Jar I can run an executable on any machine. Is this correct?
@@kristopherwerlinder6446 I think so - I know that a runnable Jar file can run as long as the machine has Java installed. So if you've got a bundled JRE (which would effectively have Java in the bundle itself) then anyone should be able to run it - just wish the wrapper could work as it would be easier than creating a bundle... I think!
very helpful video, can you please explain if launch4j is not available is there any other way for creating a package of exe file and jre so that programme can run on any operating system
why don't open che exe i follow the step but there is write error whit java:[Error: A JNI error has occurred, please check your installation and try again] from the JVM launcher and after that another error: [A Java Exception has occured]. please help
hello thanks for the great vid but in my csse it said "error: a JNI error has occurred, please check your installation and try again" "A Java exception has occurred". i have installed the java form the website and did all your instructions but that error occurred …..
I fixed the issue, just replace everything in jre with all the files in c:->program files->java->jdk jdk has more information in jre and that's why we get an error
What do you do if you have a Jar file that isn't opening at all? I have made the cookie clicker application as well and even with JRE 1.8 on my computer it won't open. I tried converting it to an executable but it doesn't run still.
The next thing you want to check is whether resource file names are correctly typed. File names are case-sensitive in Jar while not in IDE. So typing cookieimage.png to read a file called CookieImage.png still works in IDE but not in Jar. If Jar couldn't read a file, it stops there.
@@RyiSnow So, I figured out what the problem is. It's a NullPointerException because of the audio player. I took the audio player from your point and click adventure, but this doesn't want to export for some reason :/. I've been going over the code and can't seem to find a solution except to run it in eclipse.
Ah ok, I just checked my P&C code and maybe I found out the cause. If you're putting your audio files in a folder in your res folder (like res/audio), then change the code like this: from URL sound1 = getClass().getClassLoader().getResource("audio/sound1.wav"); to URL sound1 = getClass().getResource("/audio/sound1.wav"); *Remove "getClassLoader" and add " / " before the folder name. When exported as jar, the ClassLoader cannot find files in a folder created in res and I think I forgot about this when I created that tutorial.
nvm, I was able to fix it. I saw a reddit post saying to run the jar file on command prompt to see if any errors pop up. Apparently, jar files are much more case sensitive and there were pathfiles that i accidentally capitalized.
This does not work for me? I have had 3 different errors depending on the system I try to execute from. 1. is main class not found, 2. is the I see the loading circle and then nothing happens, 3. This version of %1 is not compatible with the version of windows you are running. (this last one is windows 7). any help or suggestions is appreciated. Thanks!
I did exactly what he did and in order for my exe to start in a vmware pc, I had to extract it, so the jre was visible to the file explorer. Any advice would be appreciated.
using this method, the jre needs to be visible. afaik there is no way you can put the jre inside the .exe file. the standard thing to do is to copy a local jre to the programs programdata folder, using an external installer.
RyiSnow followed your steps exactly - thanks for providing such a succinct and clear guide! However, it is not working for me - and I can see another person commenting below has had the same problem... I get the error "A JNI Error has occurred, please check your installation and try again". After this it is followed by "A Java Exception has occurred". My program works perfectly - within the Eclipse IDE it runs without any problems whatsoever. are you able to assist?
Hi, I'm not sure exactly but that sounds like a compiler/JDK error so maybe you're compiling with a higher version of Java ? Check your Eclipse's compiler settings and see if the program is complied within the maximum version that you set in Launch4j.
@@RyiSnow Hi - It looks like the latest version of Launch4J requires JDK versions 1.6.0 to 1.8.9 -- for anyone downloading the latest Eclipse package, they'll get JDK- 13. So unless there's a solution, it looks like Launch4J hasn't managed to keep up with the latest versions of JDK. Any suggestions? Alternatively I'll see if I can find another solution - thanks for your help.
You can change the compiler settings by selecting Windows>Preferences>Java>Compiler on Eclipse. If your compliance level is set as 9 or later, try changing it to 1.8 and see if it works.
@@RyiSnow Hi, great video! Does your EXE now contain the JRE? Does this mean that the EXE file takes a larger amount of memory space compared to the JAR file? I am wondering because my EXE and JAR have the same storage space indicating that the JRE is missing in my EXE file.
@@sparkfire22223 Did you ever get any sort of resolution of this issue? I've spent 3 days now scouring the internet for ways to fix this, and I haven't come up with anything yet.
