What third party tool did you use?
All I know is that you need to have the JRE installed for you to run jar files. Most Java programmers never need to make .exes. I don't know what your .jar to .exe convertor was doing so I can't say the .exe is not running.

this my java file ,i just comile using java compiler and make to byte code,and i use to change inito am jar file,then i download the tool which use to convert jar to an exe(if click the icon the file will execute autmatically in adesktop),it run in my system but when copy te file to other system it will give the error message,my question is whether it any possibility run the file without jre.we download the software in the net without have idea of technology and run it in our system for example we download yahoomessenger and run in our system without having any knowledge of their technology

I normally ship and deploy my Java applications using an installer: it installs my
jar(s) as well as a JRE on the target machine. The user doesn't know that her
machine contains any Java technology.

I do understand you: you want to create a single executable (.exe) file out of a
bunch of .java source files. I am trying to tell you (repeatedly) that this is not the
way Java works, i.e. you create executable .jar files and install a virtual machine.

In my previous reply I mentioned that you can install that virtual machine using a
proper installer. It installs the java virtual machine together with the .jar file(s) that
contain your application code.

kind regards,

Jos

Well, its not uncommon question to ask, but still unresolved. Why to install whole jre, when you made just funny applet. (anyway, Josah, what installer do you normally use?)

During my searching I found a program which functiones exactly like what I would need. See here http://www.kytara.cz/download/chords/chords12ee.zip

He copied all the needed classes(this means all imports, including implicit java.lang.*) into classes.zip and included java.exe Then the program is run by .bat which calls

java.exe -classpath cclasses.zip;chords.jar chords.ChordsAppl

so it starts the main classChordsAppl. It is awesome, it works without any jre at all and zipped it has about 1.3MB. The drawback is, that it is made in java 1.1 and I failed to remake it to java 1.6 It just wouldnt run on computer without jre.

Thanks for any comments.

If you included java.exe you have included the entire virtual machine. btw I use
IzPack for the installation of my applications.
