Make Exe files

[Rohitha]

Hi
What ever graphical application I create (with main method and inheriting
from class java.awt.Frame) cannot be run using the java vertual machine java.exe
from DOS prompt is there a way I can run these applivations. Is it possiable
to create a exe file like in C++ for example

Thanks

You should be able to run your Java applications using java.exe if you do it
correctly. Unfortunately that is all I can say about that because you have
not said what your problem is.

Thats not a problem at all. It works with JVM using java.exe

Java programs do not compile to .exe format, which is a native code format
which will run on any DOS/Windows platform without additional tools. Java
programs, however, compile to a byte-code format that resides in a .class
file. Byte-code is not the same as native code. In other words, whereas
.exe will run without additional tools but ONLY on DOS/Windows platforms,
byte-code will run on ANY platform, but will require the use of a virtual
machine designed for that particular platform to interpret the byte-code.
So... to end a long story... NO, Java programs cannot be converted to .exe
files. That would go against all that Java was meant to solve, i.e cross-platform
compatibility.

As for your problem running and awt based Java program, I can't help you
out too much. I've had no problems running awt/Swing based programs that
I've created in the past. One simply compiles the .java source file using
the 'javac' command and then executes the resultant .class file using the
'java' command.

Here's an example:

Source file: simpleProgram.java

C:\>javac simpleProgram.java
C:\>java simpleProgram

The first line will create the simpleProgram.class file. The second line
executes the file. No need to specify .class in the second line.

If the problem is that nothing happens as a result of running java on the
.class file, then the problem lies with your code.

... now back to eating that burger.

hi,

its possible to make a executable from Java files.there are many software
to make executable.i just tried using gcj under solaris env
but it dumps core.can any one knows how to make executable out of java code?

i have a another doubt,if we make a appilcation in java.can u prevent clients
to decompile and get the source code back? is there any ways to protect this?

please mail me back at deepak22j@yahoo.com

thanks,
Deepak
