It's good to be detail oriented when one works in technology.
I was exploring ODI sdk and was curious to know how one of the plugins for ODI was written.
I was looking for a decompiler which could decompile a .class(bytecode) file into native java code.
One of the decompiler plugin for java ide Eclipse is available at SourceForge.net.
For decompiling .class file to .java one needs:
1. A plugin(JadClipse) for Eclipse which is available at sourceforge.net for download: here
2. The JAD executable available here
3. copy 1 to to plugins folder of Eclipse install.
4. place 2( JAD executable) to a location (say c:\jad_home\) and set it in the PATH environment variable.
or
Go to Eclipse->Window->Preferences->Java->JadClipse and set the "Path to decompiler" as the place where JAD.exe exists.
Note: if you don't see Eclipse->Window->Preferences->Java->JadClipse it means the JadClipse plugin is not installed correctly.
5. A restart of Eclipse is required after the configuration.
6. Add the .jar file containing the classes to be reverse engineered to a project as external library
select a project->Right click->Build Path-> Configure Build Path opens below dialog box:
7. Once the .jar file is added to the project. Select a class file on the Project explorer by expanding Referenced Libraries and any .jar file within it and then select a .class file. Press F3 to see the decompiled java code of the .class file selected.
Alternatively by placing the cursor on a Java class name in the right side code window and pressing F3 also displays the decompiled java code of the class selected!
