ClassLoaderFactory (Apache Tomcat 8.0.53 API Documentation)

java.lang.Object
- org.apache.catalina.startup.ClassLoaderFactory

```
public final class ClassLoaderFactory
extends java.lang.Object
```
Utility class for building class loaders for Catalina. The factory method requires the following parameters in order to build a new class loader (with suitable defaults in all cases):
- A set of directories containing unpacked classes (and resources) that should be included in the class loader's repositories.
- A set of directories containing classes and resources in JAR files. Each readable JAR file discovered in these directories will be added to the class loader's repositories.
- ClassLoader instance that should become the parent of the new class loader.
