Using System Path Variable in Maven project - Eclipse

Question

• PROBLEM: Hello everyone! I have created a Maven project in which i am building a RESTful API, now i have created few .json files in which i want to store my JSON data in src/main/resources , but as i can see every time i make a change ( example: register a user - write in a file ) all changes get lost whenever i redeploy the WAR file or the server gets restarted/reloaded.
• Can someone please tell me how to use system PATH variable to fix my problem? I want to store files somewhere i will be able to update them without having to worry if server is being reloaded or not. Thank you in advance!

Answer 1

SMART WAY, with java configuration and classpath (unix example, launch your application this way)

java -classpath $PATH <your-class-name>

or

setenv CLASSPATH = $PATH

see unix and windows instructions.

BAD WAY, within application code

1. You can read the PATH variable from the OS environment calling System.getenv() and then looking for the "PATH" elements within the returned map.
2. Then you have to parse the string (e.g. with StringTokenizer) obtained to get each folder within the PATH variable
3. you have to look for your JSON files in each of the folder from previous point
