I was looking for a working java decompiler of late and finally ended up in DJ Java decompiler, I think i'am contented with it. compatible for Windows 7.
Here is a review
With DJ Java Decompiler you can decompile java CLASS files and save it in text or other format. It's simple and easy.
DJ Java Decompiler is Windows 95, Windows 98, Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows 7 decompiler and disassembler for Java that reconstructs the original source code from the compiled binary CLASS files (for example Java applets). DJ Java Decompiler is able to decompile complex Java applets and binaries, producing accurate source code. DJ Java Decompiler is a stand-alone Windows application; it doesn't require having Java installed! DJ Java Decompiler is not just Java decompiler and disassembler but it is also a fully featured Java editor using the graphic user interface with syntax-coloring. Using DJ Java Decompiler is easy. Select Open and load your desired class file, or just double-click the CLASS file you want to decompile. DJ Java Decompiler supports drag-and-drop functions for OLE. You will see the source code instantly! In Windows Explorer Right mouse-button pop-up menu available too. You can decompile or disassembler a CLASS files on your computer hard disk or on a network drive that you have a connection to (you must have a full access rights or just change the default output directory for .jad files). You don't need to have the Java Virtual Machine or any other Java SDK installed. But this latest release is able to compile, run, create JAR archives and run applets outside of the context of a Web browser when JDK is installed. With DJ Java Decompiler you can decompile more than one java class file at one time. This release enables users to decompile "dead" parts of code.
DJ Java Decompiler is suitable for studying JAVA bytecode. DJ Java Decompiler enables users to save, print, edit and compile the generated java code (see Why is a DJ Java Decompiler useful). Included Applet Tag Editor enables users to create applets quickly. Included "Archiver" tool is a simple archive file manager wich enables users to work with .JAR, .ZIP, .WAR, .EAR, .APK and .EXE archives (see New features in version 3.11.11.95 and New features in version 3.10.10.95). The "Hexadecimal View" - F11 shows the file in hexadecimal. This view lets you examine the file at the lowest possible level.
DJ Java Decompiler is a graphical decompiler and disassembler for Windows 95/98/Me/NT/2000/XP/2003/Vista/7 that uses Jad as its decompiling engine.
