I am using Apache FTP Server. The FTP server is uploaded through a singleton bean to Glassfish. Previously, I could start the FTP server when I used the PropertyUserManager, but I wanted to bind some JPA logic, so I wrote my own class class that implements the UserManager interface. However, I ran into a class loading problem. The slf4j-api-1.6.1.jar file and the slf4j-jdk14-1.6.1.jar file exist in the lib folder in the glass box, and I restarted the old fish.
Here's the stack trace:
