Error downloading without install version
When click on download link browser say "The connectin was reset" and the URL turns to "126.96.36.199/www.jar2exe.com/download/sites/default/files/download/Jar2Exe_x86.zip"
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
i had licensed
but linux, mac file not working
execute-> notting happend
Please `chmod +x yourbinaryfile` before run
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?
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 188.8.131.526
This is very important for me, because I would like to use code signing for my EXE-file.
I tried a trial version to convert jar to exe with encryption but my application didn't work properly and as I tried without encryption it works properly.. Pls give me any suggestions so that I can purchase license....
Which type and options have
Which type and options have you checked? You contact me directly by email: email@example.com
The "checksum:false" can only be use after activated. Please make sure you are on the pc activated.
Yes. You are right. I just used jar2exe in a trial mode. (another window account was involved)
Now it works fine!
Java runtime not valid
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
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:
What can I do?
Java Runtime Environment not found
I have the Java SDK installed. When I start the .exe generated by jar2exe, I get the error message: "Java Runtime Environment not found.". So I installed the latest JRE, and I still get this error message.
May you please advise ?
"Modify" the final *.exe
Hi, how are you? I'm trying your product and it's perfect but, I have a question.
I want to pack my final exe generated with MoleBox (to improve security) and it's impossible because exe modifications is prohibited.
Is there any way to do it?
To modify the exe is not allowed in Trial edition
After purchased and activated, there is an option at step 6 to let the final exe file editable.
There is some advices to let the exe file more safe: http://www.jar2exe.com/solutions/safety
working with UTF-8 file names
It seems that the EXE file created by your JAR2EXE doesn't work with some file names containing "strange" characters.

java.exe? javaw.exe? jvm.dll?
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.
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
File Version Bug?
On the latest version, I set the ‘File Version’ and ‘Product Version’ in the ‘Product Info’ tab, once I click OK, these values reset to defaults (184.108.40.206). Is this a bug, or am I doing something wrong?
Como integro los reportes (JasperReport) en Jar2Exe?
Hola, ya logré sacar la ruta de ejecución del programa, y ahi coloco los reportes hechos en JasperReport, y si los toma, pero cuando los quiere compilar genera errores, y con el puro Jar no me pasa eso, espero me puedan proporcionar el soporte, estoy por comprar su programa, pero depende de esto.
Lost Drag and Drop
I have a java application that uses drag and drop fucntionalities and before I run it through Jar2exe it works fine but it doesn't with the exe generated after. Do you have any ideas or suggestions to fix this?
Hving the same problem as yours, any idea how to fix it?
The generated EXE is now officially a virus (??)
So, I have used this for a long time, but right today, my friend and I suddenly got in problems with 3 DIFFERENT ANTIVIRUSES! I guess it couldn't really be Java doing this?

First, please make sure to run as administrator.
Then, not success yet, please tell me more about the problem, which version of OS ?
Include .dll files on generated .exe
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.

hi,i just reinstall the windows, and could active my jar2exe
is there anyting i could do to slove this problem?
I have a webapp which is built without a web.xml. It uses spring's Java Config to configure most of the configurations that would have been done via web.xml in the past.
I am trying to create a windows gui app out of it. I am able to package it all with embedded tomcat and create an exe. On executing the exe, the tomcat starts successfully, but the application is not available. THis is a working app and have been tested on a regulatr tomcat. So the packaging is all correct.
Do we have to do something special for a spring we app without a web.xml?
Web APP with Spring
I am also facing the same issue as Jagdish,
My spring based web application is not working,
Memory options for service
I am using Jar2Exe successfully to run my Java application as a Windows service. Would I now need to do is to increase the working memory for the Java application, like. e.g. adding "-Xmx1024m -Xms1024m to a Java command line.
Is it possible to do the same with the generated Windows service? If so, where is the right place to add the options?
Thank you for your help
Yes, please use 'option' item in the config file
Each exe file has a corresponding config file, which has the same filename with a ".cfg" as ext name.
In the config file, please use:
to specify any JVM parameters. Please refer to http://www.jar2exe.com/createdexe/config/option
Problem open Main ?
I'm testing jar2exe. I created my project but when I try to open exe file returns an exception
here the problem: http://i.imgur.com/gNTM9Qv.png
I'm using: JVM 1.8 and Jar2Exe Wizard 2.1
How can I solve this problem ?
Please pay attention to the -target when compile
This is because you are using a higher JDK version to compile than the JRE version to run.
If you are using a higher JDK version and want to run with lower JRE version, please use "-source" and "-target" parameter to specify a minimum version to run. Please refer to http://docs.oracle.com/javase/7/docs/technotes/tools/windows/javac.html and search 'target' on that page.
2 Issues with Jar2Exe on our project
I purchased Jar2exe today to package my Jar file into a executable. I am currently experiencing two issues:
1) When I run the exe the ‘look and feel’ of the Java application have been removed. It reverts from the back look and feel to a grey default look - yet if I run the JAR it works correctly
2) The exe loads the application. Then when I close the application it reopens. It only reopens once. Once again, testing the input JAR this does not occur
I would be grateful for any help with this urgently from admin or anyone who can help :-) , Thanks
It's a problem of Jar2Exe in a very detail
Thank you for your message.
This is caused by a new problem of Jar2Exe since V2.1.6 and I have fixed it. I'm so sorry for the inconvenience.
it can be cracked
I downloaded the free version，and publish a beta version，I use hide and encryp function，but it can be cracked，some people already publish they cracked result。。。so said
Please refer to http://www.jar2exe.com/solutions/safety
I'm so sorry to hear that your encrypted program is hacked. For professional hackers, we are difficult to get it 100% safe, even for Windows or iOS, so what we can do is to let is more and more difficult to hack.
Jar2Exe does 2 things to protect java program (1) confusing the filename within jar file, (2) encrypt jar file.
Besides the protection of Jar2Exe, there are some other advices on doing more steps to protect java program: http://www.jar2exe.com/solutions/safety , that is to do an (3) abfuscation and (4) exe file encryption.
I tested out your software to wrap and protect my java application. I really liked it and the application runs perfect. Except or one thing: the application is a JavaFX application, so when i run it, it does not load the css files. Even when u uncheck the protection option.
Thanks in advance,
Avoid using full of URL string starts with "j2e:"
We have discussed though email, I post here for reference.
The URL start with ‘j2e:’ should be unknown to other library. So, please use this style:
