This brief article shows how to access and open java class files.
Reference: (watch the video here)
1. Access the Java files in this directory:
C:Documents and SettingsMeApplication DataSunJavaDeploymentcache6.0
(The java files are inside a folder with numbers. you need to find which app is in which number. the jar files don’t have extension. to see them add .zip at the end of them. remember to remove the extention when finished working with them.)
2. Use DJ Java Decompiler to open the class files and convert them to java files.
