  - loadClass
```
public java.lang.Class loadClass(java.lang.String name)
                          throws java.lang.ClassNotFoundException
```
    Load the class with the specified name. This method searches for classes in the same manner as loadClass(String, boolean) with false as the second argument.
    
    Overrides:
    
    loadClass in class java.lang.ClassLoader
    
    Parameters:
    
    name - Name of the class to be loaded
    
    Throws:
    
    java.lang.ClassNotFoundException - if the class was not found
  - loadClass
```
public java.lang.Class loadClass(java.lang.String name,
                                 boolean resolve)
                          throws java.lang.ClassNotFoundException
```
    Load the class with the specified name, searching using the following algorithm until it finds and returns the class. If the class cannot be found, returns ClassNotFoundException.
    - Call findLoadedClass(String) to check if the class has already been loaded. If it has, the same Class object is returned.
    - If the delegate property is set to true, call the loadClass() method of the parent class loader, if any.
    - Call findClass() to find this class in our locally defined repositories.
    - Call the loadClass() method of our parent class loader, if any.
    If the class was found using the above steps, and the resolve flag is true, this method will then call resolveClass(Class) on the resulting Class object.
    Overrides:
    
    loadClass in class java.lang.ClassLoader
    
    Parameters:
    
    name - Name of the class to be loaded
    
    resolve - If true then resolve the class
    
    Throws:
    
    java.lang.ClassNotFoundException - if the class was not found
  - findClass
```
public java.lang.Class findClass(java.lang.String className)
                          throws java.lang.ClassNotFoundException
```
    Overrides:
    
    findClass in class java.net.URLClassLoader
    
    Throws:
    
    java.lang.ClassNotFoundException
  - getPermissions
```
public final java.security.PermissionCollection getPermissions(java.security.CodeSource codeSource)
```
    Get the Permissions for a CodeSource. Since this ClassLoader is only used for a JSP page in a web application context, we just return our preset PermissionCollection for the web app context.
    
    Overrides:
    
    getPermissions in class java.net.URLClassLoader
    
    Parameters:
    
    codeSource - Code source where the code was loaded from
    
    Returns:
    
    PermissionCollection for CodeSource
