Convert Jar to Exe

Hi,
I would like to convert my Java application to a single .exe file. I have read through many posts highlighting the advantages and disadvantages.
The reason for this is that I would like to offer my application as a commercial software and clearly I do not wish to provide users with all classes and jars...in other words, how does one go about protecting the software against pirate use?
what would be the best tool to create this 'real' .exe file that contains all it needs to run on any (windows) maching without the need of having a Java runtime installed?
My idea is to first use some obfuscator and then convert the whole thing into an .exe.
thanks

I don't know... IBM doesn't seem to worry much about this, they sell me RAD and don't bother with any of that protection business. What bad thing could happen if somebody saw your code? Remember that people don't need to decompile your classes to pirate them, they can just make copies of the classes.

and is it possible to extract my source code from executable file using reverse engineering techniques??

JAR to EXE or executable JAR conversion

Greetings all
I have a jar file placed in my java\bin folder. i want to make it into an executable .exe file. if not that i want to execute it without going on command line and writing
java -jar MyJar.jar
is there any solution?
somebody told me to make a .BAT file and run it..i dont know anything about BAT files...is there any convertor that may convert my Jar into .EXE file keeping icons + images in my program intact?

i want to make it into an executable .exe file.Please forget that for a moment and tell us what your goal is (instead of what you think the correct approach is).
if not that i want to execute it without going on command line and writing
java -jar MyJar.jarSo you want to double-click it and it should run?
If your system is set up correctly and "java -jar MyJar.jar" works, then double-clicking it should start it was well.

There is NO WAY to convert .jar to .sis... read here.

I have seen a post here:
http://forum.java.sun.com/thread.jspa?threadID=709899&tstart=0
I just want you to know, that it is NOT possible to convert .jar to .sis file.
.jar file - designed for Java (J2ME)
.sis file - designed for EPOC (Symbian)
There is no way to convert either of them, at least for now.
So stop asking for the program (in the above post), and stop giving your email address.

You can use FlashJester Jugglor to add ' Additional Files'
inside the EXE.
Download a FREE evaluation copy from
http://www.jugglor.com
and try it.
Go to the Additional Files section and when you press the

I have convert JAR to DLL using VisualCafe, how to use it in VB?

Hello all,
I have successfully convert/compile my Jars file to DLL files following the steps given in the VisualCafe Expert Edition help file.
Let say my Jars file contain the following class & method:
class1 setName(String sData)
class1 getName()
class2 mtd_Open(String sFileName)
class2 mtd_Save(String sFileName)
... so on ...
Does anyone know how to use the DLL in the VB program? Let say, I want to use the method "mtd_Open(String sFileName)" in the class "class2" in my VB program, how do I code this in VB? Please help...
Thanks for your time.

suggest that donot convert jar to dll.
use the jar in VB directly through JNI technology of SUN JAVA.

Is it possible to convert Java to EXE and run this EXE file without any JRE

hello friends
I have GCC/GCJ for windows but dont know how to work with it... it creates file with .o extension but i m not able to create .exe from that... i installed mingw for that also .. unsuccessful ...
tell me the solution for it... i want to generate machine dependent exe from java file...on the web i ve seen that GCC/GCJ is used on linux platform..not cleared properly..
Again i m writing my question
Is it possible to convert Java to EXE and run this EXE file without any JRE if yes then how... tell me the procedure to do that...

Vipul wrote:
Its software now hardware .... some times u need these things ...anyway do u ve solution for my questionSo what? By creating a native executable you are restricting the program to the OS for which that native executable was made, just like removing the engine from a car restricts driving to downhill only. So like the I said, the principle remains the same, "Why would you want to?"
I am asking you, truthfully, why do you feel the need to negate the largest advantage of using Java by creating a native executable from it?
What is your rationale?
I can pretty much guarantee there is a much better way of achieving your wish without "removing the engine".

Jar to exe is *really fragging simple* - read on...

Step 1) compile this code to xjar.bin
int main(int argc, char *argv) {
return system("javaw -jar xjar.exe");
}step 2) cat xjar.bin yourapp.jar > xjar.exe
viola, it's an exe, it can have a pretty icon, a user can double click to run, no .bat files, AND it's cross platform! because you can legally prepend data to a zip file, the exe is merely a header, for other platforms you can run the normal .bat / .jar way. (you may need to do zip -F to fix though, the kaffe VM doesn't like headered zips, sun's is ok with it though)
===
My knowledge of C was really basic a few months ago, and has rotted since, methinkst it should only take another couple of lines to do
"javaw -jar %s", args[0]
to allow renaming of the exe, but my many attempts all segfault, can someone here add to it?

still need a JVMWherever you go you still need libraries - and compare
the size of 8MB JRE download to all the gigabytes of
stuff in /usr/lib
The most common reason is because they want the appto be faster, this solution,
at least on start up is slightly slower.It starts slightly slower, and after that JIT takes
care of the rest. With the exception of array use
(with enforced bounds checking each access) and the
first time a each class is loaded, JITted programs can
run faster than CI didn't claim that it would run faster if actually compiled. I did however say that is what people think when they are looking for a compiled solution. I doubt that they will think that your solution meets that need.
>
>
The second most common reason is to "protect" thecode. This doesn't help
with that either.A) most people wouldn't even attempt to decompile
any .exe file, unless they know its a jar in disguise
B) Obfuscation helps a lot, even if it isn't perfect
C) C binaries can be decompiled to C source, just like
java. I can't remember the program (dcc?), it's still
in alpha and the author got a job and moved on before
finishing it, but it still works for small simple
apps.
D) Writing / editing parts in jasmin tends to screw up
decompilers, and they either crash or resort to
spewing bytecode mnemonics
Anywho, the point is is solves some of the problems,
without creating any new ones (unless you count the
nanoseconds for a 5KB C prog to start as a
problem...)...Again I didn't say that I wanted to do this. I argue against using any methods designed to protect code. But other people do. The slight hiding that this achieves might be what they want. Or not.

Converting jar file to .exe

hi I have installed NativeJ to convert my java application to .exe file
It was converted and it is working.
But while clicking the setup file it has to be installed in the local system .if the jre is not installed first it should install jre and it has to install our application.before installing our application to local system it has to ask the path where it should be installed.
please give me some suggestion.

Converting .java to .exe files to run those without runtime environment

i want to convert my java code to a windows application file so that when ever i have to take it to some place for description, i would not require to install java run time environment. and can show up the working of the code with the help of it..................

Converting a Java application into an exe file
This question is sometimes asked many times on a single day in the comp.lang.java.* newsgroups, and I always end up asking the same question: why do you want to? Most answers fall into one of four categories, and each prompts a different course of action. Most of the time, an exe file isn't actually required.
Reason 1: Speed
"Java is interpreted, so I want to make it native and make it faster." Well, very few modern desktop VMs actually spend much time interpreting Java bytecodes these days. Everyone and their dog has a JIT (Just In Time) compiler which will compile your code into native form before running it. Smart VMs will do this only when appropriate (ie if the code is going to be run more than once, or contains loops etc), and may recompile the code on the fly if the conditions change (eg if a subclass is loaded which invalidates some inlining optimisations, or if the code is run very frequently and therefore merits more aggressive optimisations). The bottom line is that for most applications, Java running on a VM is pretty fast these days. It's usually pretty close to the speed of a natively compiled and similar C/C++ application - certainly I've seen changing compiler (or compiler options) for C/C++ make more difference to speed than going between Java running on a VM and natively compiled Java.
There are some situations where the speed difference is significant. If you're really desperate for that extra bit of performance, try evaluating one of the native compilers listed here with your particular application. Make sure you write some real benchmarks though - vague notions of "feeling faster" may well be down to preconceptions.
Remember, too, that as new VMs come out, they tend to improve performance. That means that to get the best out of your application if it's running on a VM, the user only needs to download a later VM - no action is needed on your part. If they're using your natively compiled code, you'll probably need to recompile on a later version of the native compiler, if one is available.
Reason 2: Being able to open an application by double-clicking on it
If you can ask the user to install a JRE first, executable jar files are the way to go here. They're very simple to set up and use, and it won't cost you any money. See "Jar" in the Java Glossary for further information on how to create an executable jar file.
Reason 3: Not having to distribute a jar file and the JRE
Well, in some form or other, your users will need a runtime environment. Some native code compilers even require you to have a JRE installed as well! Chances are you're not going to be able to create a much smaller download, if that's the worry. However, there are other options here which make it easy to install your application. There's Java Web Start which also includes automatic upgrading of your software, but which will impose some restrictions (a bit like an applet, but slightly less restrictive) unless you sign your application. Alternatively, there are quite a few installers available, some of which are free (or free for personal use). See Installer in the Java Glossary for a list of some of them.
Reason 4: Intellectual property protection
Java byte-code can be decompiled pretty easily, and even obfuscators can only do so much. Here, native compilers really do make a difference. Obviously they won't make your code totally impossible to understand, but it'll be very difficult to get back to Java sources which could be modified and recompiled. The only further question to ask at this stage is whether the downsides of native compilation (eg it being a less-well-used (and therefore likely to be less solid) platform, being expensive etc) are worth the upside of the added protection. In some cases the answer will be yes, in some cases the answer will be no.
What next?
If, after reading through the above, you still want to try a native compiler, you can usually evaluate them before buying them. (Some are free, of course.) There's a list on Marco Schmidt's web-site, along with another view of the pros and cons.
I go the above article in : http://www.yoda.arachsys.com/java/javaexe.html

Javafx JAR to .exe(windows) or .app (MAC)

hi,
Anybody has any idea how can i import my javafx application to an installation file for MAC or Windows?
For example, MAC has a jar bundler app which convert java jar to .app files for MAC.
I tried with it, but it fails, i have no idea how to make it run javafx jar files.

I've looked throughout the forum but I've only found
how to call an executable from within the java code,
but not convert it into an exe.
And about googling it, I found few (maybe not using
the correct keywords, any suggestion?), and they
don't quite work well, so, just asking if any of you
have had success with one and, what is the name of
it.
Thx.can't have looked very far, then. the definitive answer to this question has been posted several times, quite recently
the real question, though, should be "do I want to bind my nice portable java code to a particular platform?"
