Constructor Detail

### JasperLoader

    public JasperLoader(java.net.URL[] urls,
                        java.lang.ClassLoader parent,
                        java.security.PermissionCollection permissionCollection,
                        java.security.CodeSource codeSource)

Method Detail

### 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

### getResourceAsStream

    public java.io.InputStream getResourceAsStream(java.lang.String name)

  Delegate to parent

  Overrides:
    `getResourceAsStream` in class `java.lang.ClassLoader`
  See Also:
    `ClassLoader.getResourceAsStream(java.lang.String)`

### 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
