I have lost my sources but I have my executable .jar file. I want to apply JAD to it.
What options to use to start UI with all source tree of .jar file?

I'd recommend Java Decompiler

Download JAD Command..
paste it in your jdk/bin directory.
type in cmd [ jdk/bin> jad -sjava example.claass ]
Link below answers u in detail:

JAD has online, in-the-cloud interface now: http://www.javadecompilers.com/

I mostly use Javadecompilers.com to decode my Jar file. The site can also decode android applications (.APK) which, I think, is very good for those who are beginners in android application development since you can learn from source code !. This is not STEALING. It is just "Break the code to see how it was made so that you can learn from it" !

I want to create an RPM package for a java application. I have never done rpm packages and i still do not quite understand how to do it manually. Is there a software that can do this (or at least most of it) automatically ?. Currently if user wants to use application he/she has to download a tar.gz file, un-tar it and then run .sh file that takes care of the installation.
My dev workmachine is Windows ( don't bully me for that ! ) if that helps at all.
I have found THIS Software but i am not sure if its applicable to what i want to do. Please note that current project set up - is NON Maven
Any help appreciated
I use insall4j for this job. There is a ant task for creating installer (and launcher)
Some days ago, I found several softwares doing that on Sourceforge.net but one of them was just a graphical interface above RPM build tools, I needed to understand what to put into a spec file and in .rpmmacros... The other one seems too simple to do what I want. Currently, I'm trying to use Redline RPM pure Java library, you can use it with or without Ant if you want. I'm still trying to make it work as you can see here.

I'm looking for a good libraries to edit .mp3 tags ID3v(22,23,24) (like author, title, track and this kind of stuff), write in java or clojure, any ideas ?
There is some standard "de facto" in this field...
I have just look at this question:
https://stackoverflow.com/questions/73147/i-need-an-id3-tag-reader-library-for-java-preferably-a-fast-one
But if there is something more would be great...
Perfect would be if the libraries supported not only .mp3 but also .ogg and .wma...
Thanks everybody, and sorry for my English...
You can use JAudiotagger library JAudiotagger
I built a Swing project last year that used JAudioTagger, and it worked great.
I only added support for mp3 to my app, but I believe it support more than that.
I know this is a bit late, but maybe it will help someone. I also wanted a library for this, so I wrote a library supporting all of the commonly used tag fields in mp3, ogg, flac, and mp4/m4a files. Source and documentation can be found here: https://github.com/DanPallas/green-tags and it is up on clojars.

looking for all in one free open source exe solution (for java ) that can be used to create an all-in-one EXE from one or more jars?
Edit:
An "all-in-one EXE" is an executable that does not require a JVM to run.
Check out the following
Winrun4J: http://winrun4j.sourceforge.net/
Launch4J: http://launch4j.sourceforge.net/
According to the project page, the GNU Compiler for Java enables the creation of native machine code.
You can try jsmooth.sourceforge.net

Where can I find the source code of the Java API?
Install the JDK. The sources for the public classes are packaged in src.zip.
OpenJDK code: Browse here
For example, if you looking for AWTUtilities.java, go here in the above link:
src› share› classes› com› sun› awt› AWTUtilities.java
OpenJDK project homepage where they have all the instructions of downloading and building it
OpenJDK Mercurial Repo hosted here
JDK Documentation here
You can also find them online at http://www.docjar.org/.
I'm not sure what you mean, but here is the API documentation
Source for OpenJDK implementation
Presumably you mean the core libraries?
http://openjdk.java.net/groups/core-libs/
You might this alternative useful too:
http://www.gnu.org/software/classpath/
If you only need to look up some classes, the following page is also a good source:
http://grepcode.com
It works for different versions of various libraries.

Hi I made a java swing application. Also created jar of that file.
Now I want to make that file in installable format (means in .exe format for windows bin format for linux X86 format).
If we install any software we get some license agreement. I want to make my jar in that format which can be installed in any platform. So is there any free and easy to use installer which can give me that feature.
Or is there any way that I can get the same installable format using java program
Thanks

Use InstallJammer. InstallJammer cannot create installer for MacOS.
Thanks
Sunil Kumar Sahoo
Better use DiskUtility or Package Maker for Mac, Visual-Studio for Windows and RPM for Linux.
