Question

What should I do if the executable file doesn't open?

Community Answer

Check if you exported JAR properly, defined all the paths, and launched configuration according to your main class. The JAR export might be damaged, in which case your .exe file wouldn't work.

Question

Is it possible to wrap an appropriate version of JRE with the executable so that the end user doesn't need any JRE installed to run the program?

Community Answer

Yes. In Launch4j, under the JRE tab, it's the first field at the top.

Question

When I try to launch, it just loads without doing anything. What should I do?

Community Answer

Check your version of Eclipse. If your version has a Package Explorer folder, then export your project to the run-able JAR file from the "Package Explorer" folder, not the "Project Explorer" folder. After that, follow all other steps as outlined in this article.

Question

Does every subclass branching off from the main get included too?

Community Answer

Everything inside the project folder which you are extracting is included. Classes outside the folder only get a reference if they are linked with your content.

Question

What do I do if I have created an .exe JAR file, but it is not showing an icon image?

Community Answer

Make sure your icon dimensions are 256x256 and that the file format is .ico according to the instructions above. However, you will probably have to export JAR to .exe again.
