I am using iexpress to make my .jar files into .exe files
for this I add the jar file(myjarfile.jar) and in run command box I type : java -jar myjarfile.jar
but after creating the .exe the cmd that is flashing says cannot find the jar file myjarfile.jar
can any body help me find what I am doing wrong
To test this, I built a simple HelloWorld.jar file (using these instructions) and tested it like so:
java -jar HelloWorld.jar
Then I made an IExpress package with it. The Install program was exactly the command I used above. This worked exactly as it should.
Two possible causes of the error:
In the IExpress wizard, there's a checkbox Store files using Long File Name inside Package. You should definitely select this option; ignore the warning that appears, as it applies to Windows 95/98. In the .sed file, this is:
UseLongFileName=1
Check that the .exe actually contains myjarfile.jar. 7-Zip will open the .exe and show you the archive contents. (IExpress .exe files are just a CAB file with a wrapper.) If the file is missing, then you'll need to check your .sed file to see what went wrong.

Actually, I'm trying to add new language to Streama Media Server. I downloaded source code, added new language file (as guided here). After that, I want to build a jar with that project, I build it with IntelliJ Idea 2021.1 (here is how I did). So, When I run that jar file (in Ubunt 20.04), it fails and gives this error: Screenshot
When you have made adjustments to the source code, it is likely that you will want to create a new .jar file and deploy it on your server. For this, you can use a simple command:
# for unix based systems
**./gradlew assemble**
# for windows
**./gradlew.bat assemble**
This will create 2 new .jar files under build/libs,
streama-{version}.jar
streama-{version}.jar.original
all you will need is the streama-{version}.jar.
This file is an executable, so you can just copy it into your deployment directory / your server and start it as usual.
I am programming a Qt application in MS Visual Studio Community 2019. I am trying to add an icon to my application window with the following command, and I also have the corresponding file my_icon.ico mentioned in the .qrc file:
setWindowIcon(QIcon(":/my_icon.ico"));
When I build and run my program in VS, everything is perfect - the icon replaces the standard one. However, when I make a release and try to run the resulting stand-alone executable, the icon is NOT shown! This is particularly weird as images which I also mention in the .qrc file (pictures for buttons) are on their places.
I have tried to put my_icon.ico alongside the .exe file, but with no result.
I give up, please give me a clue what might be happening here.
Thanks to chehrlic, I understood that it was as simple as running the windeployqt.exe on the .exe file build by the Release configuration by Visual Studio.
This will link all required libraries dynamically.
Avoid using this tool while the .exe file is inside the Release folder as it will create many other files & folders near .exe file. I have copied my_app.exe to a fresh directory and ran the following command from it:
C:\Qt\5.14.1\msvc2017_64\bin\windeployqt.exe my_app.exe --release
See https://doc.qt.io/qt-5/windows-deployment.html for more details.
Recently I encountered a problem when using exe4j to package the jar into exe. My xml configuration file is placed in the same directory of the exe, but after the package is completed, the exe will look for the xml file from the temporary folder.
These are the instructions in the exe4j help documentation
For some applications (especially GUI applications) you might want to change >the working directory to a specific directory relative to the executable, for >example to read config files that are in a fixed location. To do so, please >select the Change working directory to: checkbox and enter a directory relative >to the executable in the adjacent text field. To change the current directory >to the same directory where the executable is located, please enter a single >dot.
The error when i running the exe :
[ERROR] In Log's init,cann't read config file, file=/C:/Users/**/AppData/Local/Temp/e4jEA8.tmp_dir1543543191//sys_log.xml
Why is the program not looking for this xml from the exe's sibling directory, and how can I find it from this directory?
If you are using the "JAR in EXE" mode, use
System.getPrpoerty("install4j.exeDir")
to get the parent directory of the executable.
I wanted to convert .java file to executable jar file,i did so in the command prompt. But everytime i double click (open) it nothing happens.
jar cf Calculate.jar Calculator.java
This is what i typed in the cmd. How to get an executable file? I use windows
That's not how it works, that way you are creating a jar archive with that .java file in it.
If you want to create the jar manually (if you want to do it one time, instead of using a build tool like ant or maven, it could have some educational value), you have to compile your .java file to a .class with javac, add it to the jar and then modify the META-INF/MANIFEST.MF manifest file to specify Calculator as value for the Main-Class attribute.
See this old guide from Sun.
I'm trying to run the texteditor.pro file in the QtSDK\Examples\4.7\tutorials\gettingStarted\gsQml directory with Qt Creator. When I try to build the project I get a window that says
Could Not find the executable, please specify one
with three fields to load files. Snapshot of the dialog box.
I'm running windows 7 64bit, with Qt Creator 2.4.1
I've solved the problem it was a missing dll file, but the executable didn't ask for it, so I put all the dlls from Qtcreator -> bin in the same folder with the *.exe file, then I deleted file after another until I figured out what files are required.
* It is a brute force way, but It did the job.
* Here is the file that were missing (libEGL.dll)
This project is not created in the normal 'Qt-executable' kind format. Rather its a 'plugin' kind project. So you cant run it directly like other projects.
[If you will open the project files you wont find a main() function!, which is supposed to be the entrance point usually for a C++ Application. All you have are a couple C++ classes. Take that as a hint]
About this example they have given the complete details here. And I quote:
We need to compile the file dialog C++ plugin before the text editor
can run. To compile, enter the gsQml directory, then run qmake and
compile using make or nmake, depending on your platform. To run,
launch qmlviewer and open the texteditor.qml file.
Else:
You create your own project.
Add these class files and the respective qml files to this project.
Add a main and create the respective objects required.
Make an application viewer and give "texteditor.qml" path as its source.
I had the could not find executable window pop up in my face in Ubuntu 12.10.
Here's how I got the "error":
Created a folder named Project;
Inside it, I ran "qmake -project" and then "qmake";
Created a main.cpp file inside the folder;
Opened the Project.pro file with Qt Creator and added the line "SOURCES += main.cpp" to it;
Pressed Ctrl + R to build and run the project.
Later on I deleted the folder and created it again, but this time creating a main.cpp file before trying to run any commands. I opened the .pro file with Qt Creator, created a main function in the main.cpp file, and pressed Ctrl + R, and it built and ran!
