Finding bugs in your code using FindBugs

Static code analysis is the analysis of the software that is performed without actually executing the program. The process provides an understanding of the code structure and can help to ensure that the code adheres to industry standards. Static analysis code reviews compare the source code of an application with a set of standards to ensure the source code compiles with those standards, to find unwanted dependencies, and to ensure that the intended structural design of the code is maintained. The main advantage of static analysis is the fact that it can reveal errors that do not manifest themselves until a disaster occurs.

Installing Jadclipse in Eclipse

Today I am going to show you how to install and use Jadclipse. Jadclipse is eclipse plug-in that integrates Jad (Java decompiler) with Eclipse.

  • First you require Jad for decompiling java files. You can find a list of mirrors on this site where you can get JAD for various platforms. Download it and unzip into any folder on your hard drive.
  • Next download the Jadclipse plug-in jar file from here and place the jar file in your eclipse plugins folder
  • Restart your eclipse. If eclipse didn’t recognize the plug-in then launch eclipse with -clean flag.

eclipse -clean

  • Configure the path to the Jad executable in eclipse under Window > Preferences… > Java > JadClipse > Path to Decompiler.
  • Set the full path of the jad executable, e.g. C:\Program Files\Jad\jad.exe
  • Go to Window > Preferences… > General > Editors > File Associations and make sure that the JadClipse Class File Viewer has the default file association for *.class  files.
