Mac Executable

Submitted by veerendra on

Hello,

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

Please help me on this

Mac Excutable

Submitted by Veerendra Jetty (not verified) on

Thanks for reply, Yes i did 64 bit executable, but i don't understand 2 point. Please explain steps to make MAC executable and running on MAC

Need to `chmod +x` when copied to mac

Submitted by Sswater Shi on

On Linux and Mac, executive files need to have execute privilege to run. Right now, Jar2Exe can run on Windows only, but FAT32 or NTFS could not express the `execute privilege`. So, after generated exe file is copied to Mac, we need to use `chmod +x (binary file)` to add execute privilege to let it runnable.

Generating for Mac ok but when I codesign the executable

Submitted by David Hubbard (not verified) on

hi

I'm using Jar2Exe fine in most cases but have hit a slight problem when generating for "mac" and applying codesigning to the executable.

to codesign I run

          codesign -s "MyCompanyID" ./MyAppExecutable

But when I run this I get

$ ./MyAppExecutable

Error occurred during initialization of VM
java.lang.Error: java.lang.ClassNotFoundException: com.regexlab.j2e.Jar2ExeClassLoader

I have  "/checksum:false" set already BTW.

Is there a way round this ?  I'm sensing there is some overlap in how Jar2Exe and codesign define the executable header info.

Thanks

 

 

 

 

64-bit service EXE not working

Submitted by hs on

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

 

64 bit exe could only run with 64 bit JRE

Submitted by Sswater Shi on

On 64 bit Windows, 32 or 64 bit of JRE can run. Both 32 and 64 can be installed together.

Your "java -version" shows that, your JRE is not 64 bit edition.

Jar2Exe doesn't recognize the main jar file

Tried the helloworld and it worked using the command line.

I then moved the jar and class files of the program to be exe'ed to the root directory (c:\) and successfully compiled the files and program. Thank you.

It seems that the directory where I currently have the files no longer is acceptable to Jar2Exe program. That was the cause of the Jar2Exe program not recognizing the main jar. Seems that Jar2Exe relies on Windows to locate the files where the "previously" compiled jar and class files resided. When the PC "user" location naming was changed,  Jar2Exe still looked for it in the directory under the older user. Probably a Windows created problem of providing the Jar2Exe program wrong location info.

I Cant Activate anymore

Submitted by brazukassp on

I order jar2exe in 2016 and know i can activate anymore, can you helpe me ?

Extend trial

Submitted by Rick Ruble (not verified) on

I sent an email requesting to extend the trial. I was told to create a new account, so I did. I get an email for one time login, I sign in. I then have a choice to send a password to my email but entering a captcha continually fails with the following message.... I guess I can't paste the message here.. It says session reuse attack detected. The answer you entered for CAPTCHA is not correct. I have tried using IE, OPERA, and Firefox. This is getting very frustrating in order to extend a trial for a product that I am interested in.

 

 

 

mac, linux not working

Submitted by bishop on

i had licensed 

 

but linux, mac file not working 

 

execute-> notting happend

 

please help 

 

 

Please `chmod +x yourbinaryfile` before run

Submitted by Sswater Shi on

Because the windows filesystem could not express the "execute" privilege, after you copy your generated binary file to Linux and Mac, please `chmod +x yourbinaryfile` first.

In the future release I'm thinking to generated a ".zip" file instead to contain the "execute" privilege.

Parameter /checksum:false doesn't work?

Submitted by taulatin on

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.

Java runtime not valid

Submitted by ErikK (not verified) on

I've just downloaded a demo version and tried building an .exe. The wizard seemed simple enough to use although it surprised me I never had to specify where the jre I'd like to use is. When I execute the .exe however I get the following error message:

C:\Program Files\Java\jdk1.8.0_91/jre\bin\server/jvm.dll is not a valid Win32 application.

Java Runtime Environment not valid.

EXE crashing when using Hide or Encrypt option

Submitted by carlosteiner75 on

I am creating a java APP and uging jar2exe to distribuite it as a exe file.

I have the following issue: when using the "Hide class files" or "Encrypt and hide class files" option my application craches when opening a certain JFrame for the second time. In other words:

1. I open my application: OK

2. I open a certain form to input some data: OK

3. I reopen the same form to input other data: crashes

Using other forms it is OK, I do not know what to look for.

If I use the original .jar or I do not use Hide or Encrypt option it works fine. 

Here is the generated error file:

https://dl.dropboxusercontent.com/u/42217759/hs_err_pid9988.log

What can I do?

 

Thanks

Splash Screen

Submitted by Quantina on

Hi,

I setup everything and it works fine, except the splashscreen doesn't close. I tried it with both jpg and gif but it just stays on the screen. Is it possible to use the custome congif internal to close it after 3 seconds or something similar? If not how can I integrate it into my Java project as the documentation on the site is quite old and I wasn't able to do it.

Thank you,

Sign

Hi, is it possible to generate an exe file that is "digital signed", in order that if I put the exe file into a web server, available for a download, the browser wouldn't say "This file is made by an unknown author"?

Thanks a lot

Include .dll files on generated .exe

Submitted by Nicolò Ghielmetti (not verified) on

Hi,

I would like to know if it there is some methods to include .dll files which do not appear in JRE/bin folder (ex. rxtxSerial.dll). I tried to include a .zip which contains the .dll file but using NetBeans (the IDE which help me to develop my Java application) but my .exe does not work without rxtxSerial.dll put on the same folder. Can I resolve this problem with J2E? Or with NetBeans?

Thanks in advance.
