JniLifecycleListener (Apache Tomcat 10.1.56 API Documentation)

java.lang.Object
- org.apache.catalina.core.JniLifecycleListener

All Implemented Interfaces:

LifecycleListener
```
public class JniLifecycleListener
extends java.lang.Object
implements LifecycleListener
```
An implementation of LifeCycleListener that loads a native library into the JVM.
Native libraries are associated with the class loader of the class that loaded them, and the same library may not be loaded by more than one class loader. Due to that restriction, loading a native library from a Webapp's class loader makes it impossible for other Webapps to load the native library.
Loading the native library using this listener solves the issue as it is loaded by a shared class loader (typically the Common class loader, but may vary in some configurations).
