mais un problème est survenu sur eclipse:
Citation:
java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Unknown Source)
at java.util.Properties.load0(Unknown Source)
at java.util.Properties.load(Unknown Source)
at exemples.AuthExample.<init>(AuthExample.java:43)
at exemples.AuthExample.main(AuthExample.java:84)
Ce que j'ai compris est que le problème provient du fichier setup.properties mais je n'ai pas compris comment le corriger.
Pouvez-vous m'aider?
