In real time projects when working on a large team, it is the duty of the developers to regularly commit their work to the repository (SVN/GIT) to ensure they maintain everything in place, version control and avoid conflicts upon merge due to parallel developments.
However, in times of a repository/workspace crash it becomes impossible to fetch the last deployed project version for the developer to work on enhancements/bug fixes/change requests as we need to recreate the Application structure.
The only artifact available to the developer is the last deployed BAR file which is present to the server.
Application Project contents are lost due to repository crash or workspace issue. We need to recreate the Application projects from last deployed BAR file.
If your Application has java projects, the Bar file stores the related java files as a *.jar file.
The steps to extract the *.java files from *.jar files are below,
Note: Ensure the project does not throw any compile errors and deploys successfully after the reverse engineering process.
