Hi I purchased Jar2Exe as the free trial limitation does not show the self checksum checkbox and I kind of figured this needed to be cleared in order for subsequent codesigning of the app to work correctly.

It seems that I might be wrong as now with the full license and "sef checksum" unchecked I still generate a perfectly working app

THAT IS UNTIL I CODESIGN IT

So codesigning obviously modifies the executable (by appending the signature block at the end) and NOTE I figure its some sort of self extractor executable!!!

codesign --deep --force --timestamp --sign "Developer ID Application: My codesigning ID"  MyApp.app

Normally I would also add the hardened runtime option and also notarize the app but since I figure its just the codesigning which messes it all up I tried just signing on its own!

Once the app has been signed (and I'll wager that actually just adding anything to the end of the exe file will bugger it up) thats it GAME OVER - the app wont work.

So since signing and notatarization are mndatory or MacOS apps I ask the following question.

HOW DO I CODESIGN and still have a usable app?

I note that if I codesign (never mind even getting as far as notarizing and stapling) THEN the (launcher app itself) crashes like this....

Now I note from the call stack that this has to be in the generated MacOS laucher App since the call stack shows what appears to be C++ code and matches strings present in the generated executable. 

I also note that as long as I dont use the encrypt option that the executable can be launched as if it was the jar file itself

e.g

java -jar exefilename

UNLESS it has been signed!!

in which case you get  something like this...

java -jar Terra-DV.app/Contents/MacOS/Terra-DV

Error: Invalid or corrupt jarfile Terra-DV.app/Contents/MacOS/Terra-DV

I await your advice as I do not wish to conclude that for MacOS this product is unfit for purpose.

Kind regards,

Dave

Hello, can I use my Jar2Exe executable with VMProtect? Are there any extra steps I need to take to make it work?

Hello,

I have been using .exe app from 3 years, recenlty after updating to V2.5 unable to convert to exe, I'm using same jar file which converted successfully in previous version of .exe.

Please help me, I'm  stuck in middle.

Thanks

Hello,

I tried to make executable for MAC, but it doesn't work.

Please help me on this

Bought JAR2EXE recently and I cannot get it to work...

I am trying make a 64-bit service application.
I thought that Jar2EXE would find JRE automatically but the EXE file built always fails with either Java Runtime Environment not valid or Java Runtime Environment not valid.

However, java binary is found just fine:

c:\Users\Bruger\Desktop>java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) Client VM (build 25.181-b13, mixed mode, sharing)

Since I am planning on searching for (and installing the JRE itself if missing) in my application's setup, please show me a configuration that can either always find the installed JRE or alternatively, please tell me exactly which files from the JRE directories that need to be placed relative to the service binary's directory in order for the JRE to be found ??
 

Thank you in advance

i get a "class does not exist, are you sure it is right? 

Improve for personal Jar2Exe and I have not yet received the change

i had licensed 

but linux, mac file not working 

execute-> notting happend

please help 

May you check command line parameter: /checksum:false 

It didn't work for me. But, it works well if I use GUI in j2ewiz.exe

I used available on your site version 2.1.7.1096

This is very important for me, because I would like to use code signing for my EXE-file.
