Handle multiple Jdev installation in a single machine

Jdev create a system folder for its running, this folder store a lot information inside this folder. This folder responsible for


1. Storing the information about the projects open in the jdev.
2. Storing the code change (History information) of the projects.
3. Domain (Server) information.


Normally this folder is been created (hopefully you are using windows  machine) in your C:\Users\<yourUserName>\AppData\Roaming\JDeveloper. You can see a folder name as system12.*.*.


This folder is an important folder, if you are facing some server related issues, better to remove this folder as this will remove entire sever installation.

Once you run the server again from jdev it will re-create this folder, with server.


Some times you might be running multiple jdev in your machine, and want this folder to be generated in specific directory, you can do by

1. Changing this in jdev conf.

2. Creating a batch file and always running the batch file to run the jdeveloper.
