hi arun,
1st thing.. don't compare java with vb.. it hurts...
.class file cannot be convered to .exe file as .class files are nothing but
bytecode files and they can be run on any operationg system implementing
JVM (Java Virtual Machine)
this makes java write once run anywhere.

Yes, VB can create an .EXE file, but to distribute it to another computer
you have to send the Visual Basic support .DLL file with it -- 1.3 megabytes
in size for VB5. When you take that into consideration, having to send a
JRE to support a Java class file isn't quite so bad.

Certain IDEs can create .EXE files. Visual Cafe 3 Professional can do this.
The actual .EXE is small, but you need at least one 2.5 meg dll file when
distibuting. I think that IBM's Visual Age can as well.

Good Day,

I don't think arun is comparing Java to VB in the technical sense but rather
that he would like to run a Java Application so that appears outside of the
browser (like an app). It would be nice to know the steps to achieve this.

Java is superior to VB (duh), but that was not the question.

Visual J++ is great for making .EXEs as well as COM DLLs in Java, but hurry
while you can still get it!

By the way, for those of you with cloudy heads, don't believe the "write
once, run anywhere" hoopla crapola. It doesn't work as smoothly as they'd
like you to believe. I think Java is an OK language, but it's not magic...
I keep my options open and I haven't sold my soul to Sun or become an evangelist
as some of you people have.

And to say that it hurts to compare VB to Java... PU-LEASE. Java is just
another programming language, so get that JVM out of your *** and DEAL WITH
IT!

Hi:

There are some utilities available in the market such as TowerJ (http://www.towerj.com)
which perform a procedure called as POST-COMPILATION of the bytecode to a
TARGET PLATFORM.

This makes sense if you want to do your development in Java but want to DEPLOY
only on a SPECIFIC PLATFORM (Run Anywhere means nothing in this case!). This
case is frequently seen when you develop custom server side applications
(i.e. not compliant with J2EE!)

I believe TowerJ can target your Java code to many platforms such as Win32,
Solaris, Linux, HP-UX etc.

Hope this helps

cheers

Dear Arun,
It is not possible to convert class file to exe. To run exe
file v should have corresponding dll file. To run the class file v should
have jvm.

It's interesting in this day and age of technological advancement and innovation
that anyone can take a stand that includes the word "CAN'T". (I've noticed
you can do almost anything if you just look at it long enough)

You CAN convert a class file to a .exe using come IDE's, as mentioned in
a previous reply to this question, I do it often with Visual Cafe. There
are also some other third party tools out there that will convert a class
to an os specific binary. Try searching for Java Converters on Yahoo.

Hope this helps.

This isn't a conversion, but it provides a simple "EXE" wrapper.
Compile it and then copy the EXE to the EXE name you want.
For example, if your "application" is called "mycalc", copy this EXE to "mycalc.exe".
When the user runs it, it internally generates the Java execution command
line and launches a child process then exits.
I've had some problems with parameter passing that I've been unable
to track down. For the most part it works.
Note--your user still needs the JRE or JDK and any other Java-related
components required for your application.
Have a nice day!

I'm relieved to know that are still sane people in this techie world! Andy,
I couldn't put it in any better way!
I've been a VB programmer for years, doing Java for the last 2 and although
I agree that Java IS a better language, after a few real world experiences
with the 'cross-platform' crap I can safely say that Java has a loooong way
to go.
God, I miss Visual Studio....
