Java decompiler
Sometimes I use java decompiler, so I know so easy is to decompile a jar file and get the code.
Know, I want to make a jar file, to encrypt somethig, so I shoult have the code secret.
anyone knows how o do it?
Thanks.
you can crypt .class files and write your own class loader that can read&load them normally...
you could also compile the whole think to .exe but the only prog I know of that can accomplish that is Excelsior JET... and it's big and expensive... but you can try out the trial..

Java Decompiler for Inner classes
Hi,
I am looking for a Java Decompiler that can handle the decompiling of inner classes fairly well. Any help will be appreciated. Thanks.dj decomplier is probably the best one. u can look for it on google.

Hi there,
Can anyone recommend a good and free or trial java decompiler that decompiles jar/class file back to source code?
I had use Mocha, but some of the class file it fails to convert.
Any help please?
Thanks.Just do a search of the forums (upper right corner of the page) and get a list like this

Guys, what's the best java decompiler (accurate and reliable) out there today?
I never said a developer will never be in need ofa
decompiler. That's why I said after the onesentence
you quoted: "Without some more detail, I think
it
is justified to point the OP to a searchengine."
I was just providing an example of one thathappened
to me.I believe this would have happened to most of us.
Fortunately for me, the application only had 10 odd
classes.And that's why any project that's worth anything has a source control system in place...
Bad enough to loose a day's (or a few days') work in a harddisk crash, worse to loose manmonths worth due to something like that (or worse, your network being vandalised as happened to a company I worked for once, we had to revert to a 1 month old backup tape, all later tapes had failed). -
Hi,
im a fresher in java
im trying to develop my own java decompiler which translates class file to java file ,can anyone help me please how to start and give some guidelines .. wud b really helpful
looking forward for your support .. thanks !!A decompiler is a very advanced project to take on, not for a "fresher".
1. You must write a disassembler first.
This involves being able to parse the binary class file, and convert it into java
byte code instructions.
As mentioned, the class file format is documented here, and is the sole reference I needed to write a disassembler.
http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html
2. After you have the disassembled instructions, you can then try to reassemble
them into higher level java source code.
This isn't a trivial project.
In my free time, I spent ( on and off ), 1 year writing my own disassembler to support Java 1.5, and I haven't even attempted a decompiler ( yet ).
It has 279 classes, most fairly complex.
Just to give you an idea of my experience, 7 years java, 5 years C++ and assembly. And you'll need some experience/concepts of assembly language to work out the stack frame to break the java byte code instructions into java statements.
In my opinion, you're better off experimenting with the BCEL ( byte code engineering lab ), to extract details about the class file.

Well ... I`m working on Java Decompiler Project as my
College Project.Now, my softare is already decompiling
simple programs but i`ve got stuck now at decompiling
characters, short ints & bytes because all of them are
stored as integers according to JVM Specification.
Simply,
These 2 Statements :-
int a=97;
AND
char b='a';
Result in same set of ByteCode Instructions :-
bipush 97
istore_<n>
Now, how can differentiate between the 2 so that i can
regenerate the source file ?
Any help is appreciated !!
Thx
AmitHi,
If you're talking about class variables then the type is in the "Field Info" structure of the class file.
http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#2877
If you're talking about local variables, then there's a LocalVariableTable structure, per method which has that information.
http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#5956
The localVariableTable information is only available when a java source is compiled with debugging information.
What I done, when I'd no localvariabletable in the class file, was to create my own dynamic localVariableTable object, and fill in the types based on the operations performed on them, or their operands type.
I'd use the narrowest data type to start with, and widen it as needed.
So, in your example, it would guess character, until another operation conflicted with that. It's not bulletproof, but better than nothing.
regards,
Owen -
What features would you like to see in a Java Decompiler?
Hello all,
(I'm assuming if you're viewing this thread you use(d) a decompiler for development purposes).
I'm just about to embark on my final year dissertation for university and I am going to develop a Java decompiler.
I have researched existing decompilers, e.g. Mocha, DeJaVu etc and have come up with my own feature set, but I was wondering what other Java developers would like to see in a decompiler. e.g. Support for Generics (and other v.5 features)
So please let me know of anything you would like to see in a decompiler; possible IDEs to plug into, GUI, backwards compatibility, possible plugins, J2EE support, anything at all...
Thank you for your time.
Cheers, joeSupport for DICOM SR, DICOM SEG, and Annotation and Image Markup (AIM) as output formats for the segmentation and reports would be helpful.
It would also be great to see support for native DICOM files as input rather than needing to convert to one of the other formats you currently accept. -
Issue with Java Decompiler, please help
I'm using Mocha to decompile a *.class file from the standard OAF. I'd like to reuse some logic which Oracle has previously developed. I'd like to decompile DetailDataInputCO.class but Mocha errors out with "Ignoring field attribute Synthetic".
If anyone has a good decompiler, could you please decompile a class file for me. Please contact me at [email protected] and I can send you the file. It would be greatly appreciated.
Thanks,

Is there a good, free decompiler that is written in Java? If not, is there a reason? I'd like to be able to decompile/compile code directly from my running java code, and using Jad and javac is pretty clumsy for that.
I know there are some clumsy and unsupported workarounds for compiling code from java, but it really seems strange that there isn't a standard API for that...Sorry i don't know the answer for your problem. Though let me mention that javac isn't pure Java anyway - it doesn't adhere to the JLS (the Java Language Specification) completely, whereas - for example - jikes is 100% JLS compliant.

Decompiler problem of java class..its urgent. Please help
When trying to open a class through Java Decompiler, error message "jad.exe has encountered a problem and needs to close. We are sorry for inconvenience." is shown. The class file (when compiled through build ANT set-up) is getting corrupted for uknown reasons. However, when the same source is compiled through Jdev, the classfile is perfectly ok.
Note: Both the JDev and Build env are pointing to same jdk version (1.4.2)did you try to investigate the differences in the configurations for the ant build and the one with jdev?
-
Experts, why there is a Decompiler for java??? explainations needed...
hi guys,
I don't understand why the java class files can be decompiled into original source code. What is the benefit of that? This is against intellectual property. Nobody wants their source code to be view by other people, especially if your project is critial and vital to your business!!!!!!!
I tried the "DJ- Java Decompiler", the source code it produce is almost identical to the original. Sun has always claim java to be a secure language, but the java class file itself is not secure at all in the first place!!!Decompilers also help people better understand code in an advanced way to use it better. I know I use the sun Java files for common java.lang and java.util classes to make sure I'm doing it the best way possible.
If you have the software are want to violate Intellectual Property, you could just copy the executable and sell that. Decompiling and recompiling a program to steal it seems like a long road to no-where.
Decompilers are about understanding the code.
IP is what you do with a document when you have it. If your respectful and use it as it was intended to be used, then the more you know about it, the more legal benefit you will gain from it. Violating IP is about wrongfully transferring information, not about understanding things you legally have in your possession.
However, what courts may consider fair use is always declining. Soon you'll only be able to listen to the first half of the songs on a CD and after that they'll probably declare that you're stealing if you pay some special 'second-half' royalty fee.
If you understand how to do things, then you can just write it yourself, and better, without resorting to stealing. -
Sun, please kill the Java pirate - Decompiler
I respect the "Java Decompiler" creator, what was the motive he/she created this tool? I used this tool before to decompile a full blown Java program, amazed me much and "happy" too I can learn how the software creator created such an amazed program. In other side, sad about that his/her program being "naked and raped by a pirate"!!. How to fight against Java Decompiler? Does Sun doing something on protecting the intelligent asset of other people?

Does Sun doing something on protecting the intelligent
asset of other people?This is an age old question that is not only true in Java, but all languages. Don't ask Sun, they haven't any liabiity in it, nor should they. As in all cases, if you don't want anyone looking at your code, don't publish it. If you have something you are going to sell, then you have a choice to make: how difficult do you want to make your code to read when decompiled (notice it is WHEN and not if). If it bothers you, then forget all the good object oriented design you've had and take some real effort in leaning to make you code unreadable, then put it through and obfuscator, at least then when it is decompiled it will still be hard to read.
Is there a way to make sure no one can ever steal your code? Sure, don't connect your computer to the internet, don't publish, and don't let anyone ever see the source or your ideas, but then they could steal your computer and your source would be on it. So the answer to the eternal question is: "NO! There isn't any way to be sure no one can ever see your source." That could be why when you have a new product, even the large companies figure they only have a 6 month lead window at best. Your competition is going to get your product the first chance they get and decompile it (or tear it appart if it's hardware), look at it, and make a product to compete with it. They may not use your code directly, but they will use your ideas and find out how to do anything that you have developed that is "new".
I will give you a classic example here that I personally know of: When IBM came out with the AT, Tandy (Radio Shack) got one, took it into the lab, and cloned it and called it a model 3000. Yes, they did a true cloning right down to the ROMS (they still said IBM in them). The day Tandy, Radio Shack, release their "Model 3000", IBM had lawyers sitting on the front steps of Tandy HQ. Since the ROMs even said IBM in them, it was not a contest.
Can you protect your code: NO! Just remember not everyone in the world is interested in stealing your code. Most will just buy it and use it. Those that really want to steal it, will do so, in one form or another. You may slow them down a bit, but any one that really wants to is going to see it in some type of source--no matter what language you use and strategy you use to stop them. -
Can anyone tell me about the suitability of Java for development of commercial standalone applications? I heard that there are tool that can decompile ".class" files to obtain the source code. Is this always feasible? Does this make any java application "open source".

Unless of course - as the OP says - it's been compiled.
You can decompile the Java byte code with a Java decompiler
(use Google),
but you cannot restore if from there to CFML. It's a one way
trip.
To the OP: how did you lose your source code? You've got a
serious
procedural (in the "work place" sense not the "programming
paradigm" sense)
problem there, which you ought to be looking at. Where's your
source
control?

Can Mail be used as a "cloud" interface for GMail to conserve drive space?
I just switched to a MacBook Air which has made me conscious of my SSD drive space. I have 4 GMail accounts, for which I'd previously used MailPlane which worked well for me, although it's butt-ugly (as is GMail). I love Mail's new look, but I'm c
