 public final class ClassLoaderFactory extends java.lang.ObjectUtility 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.
- ClassLoaderinstance that should become the parent of the new class loader.
