Bootstrap (Apache Tomcat 8.0.15 API Documentation)

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

```
public final class Bootstrap
extends Object
```
Bootstrap loader for Catalina. This application constructs a class loader for use in loading the Catalina internal classes (by accumulating all of the JAR files found in the "server" directory under "catalina.home"), and starts the regular execution of the container. The purpose of this roundabout approach is to keep the Catalina internal classes (and any other classes they depend on, such as an XML parser) out of the system class path and therefore not visible to application level classes.
