How to convert a java class into an .exe file in windows or unix based OSes?

[Nik]

Hi,
Can one convert a java class file into an exe .I know doing this is against
the whole point in using java to write such a code but some performance gains
might be possible if we get a direct exe which does not have to be interpreted
everytime.
Please help me out !!!
Any suggestion will be welcome!!
Thanx in advance!!

Go take a look at Visual Cafe from WebGain... Uses the Symantec C/C++
compiler to turn Java in to a native Win32 app.

Any major drawbacks with such compiler while producing EXE. Does the sizes
& speed are greatly vary with C/C++ compiler.

and also Any brenhmark testing on SPEED.

Hi,

This is a very common question asked in the comp.lang.java newsgroup. Its
often useful to have an executable application when deploying your applications
to a specific platform, but remember to make your .class files available
for users running Unix/Macintosh/other platforms.

Microsoft provide a free system development kit (SDK), for Java, which includes
the jexegen tool. This will convert class files into a .EXE form. The only
disadvantage is that users need a Microsoft Java Virtual Machine (JVM) installed.
If your target platform is Win32, you can either redistribute the virtual
machine, or raise the level of your system requirements, to include Windows
98, or Windows 95 with Internet Explorer 4. Systems matching these requirements
will already have a copy of the Microsoft Java Virtual Machine installed.

Note : You must specify all of the class files your application needs (except
for standard java packages) as a parameter, so if you have third party libraries,
you'll need to include them as well. You can use wildcards * though, and
you don't need the original source code.
