## org.apache.catalina.startup
Class ClassLoaderFactory

    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.
