loadClass
public Class loadClass(String name)
throws 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 ClassLoader
- Parameters:
name
- Name of the class to be loaded
- Throws:
ClassNotFoundException
- if the class was not found
loadClass
public Class loadClass(String name,
boolean resolve)
throws 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 ClassLoader
- Parameters:
name
- Name of the class to be loadedresolve
- If true
then resolve the class
- Throws:
ClassNotFoundException
- if the class was not found
findClass
public Class findClass(String className)
throws ClassNotFoundException
- Overrides:
findClass
in class URLClassLoader
- Throws:
ClassNotFoundException
getPermissions
public final PermissionCollection getPermissions(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 URLClassLoader
- Parameters:
codeSource
- Code source where the code was loaded from
- Returns:
- PermissionCollection for CodeSource
