Class RMIClassLoader


public class RMIClassLoader
extends Object

This class provides a set of public static utility methods for supporting network-based class loading in RMI. These methods are called by RMI's internal marshal streams to implement the dynamic class loading of types for RMI parameters and return values.
Since:
1.1

static String
getClassAnnotation(Class cl)
Returns a string representation of the network location where a remote endpoint can get the class-definition of the given class.
static ClassLoader
getClassLoader(String codebase)
Gets a classloader for the given codebase and with the current context classloader as parent.
static RMIClassLoaderSpi
getDefaultProviderInstance()
Returns the default service provider for RMIClassLoader.

Method Details

getClassAnnotation

public static String getClassAnnotation(Class cl)
Returns a string representation of the network location where a remote endpoint can get the class-definition of the given class.
Parameters:
cl -
Returns:
a space seperated list of URLs where the class-definition of cl may be found

getClassLoader

public static ClassLoader getClassLoader(String codebase)
            throws MalformedURLException
Gets a classloader for the given codebase and with the current context classloader as parent.
Parameters:
codebase -
Returns:
a classloader for the given codebase
Throws:
MalformedURLException - if the codebase contains a malformed URL

getDefaultProviderInstance

public static RMIClassLoaderSpi getDefaultProviderInstance()
Returns the default service provider for RMIClassLoader.
Returns:
the default provider for RMIClassLoader

getSecurityContext

public static Object getSecurityContext(ClassLoader loader)

Deprecated.


loadClass

public static Class loadClass(String name)
            throws MalformedURLException,
                   ClassNotFoundException

Deprecated.


loadClass

public static Class loadClass(String codebase,
                                 String name)
            throws MalformedURLException,
                   ClassNotFoundException

loadClass

public static Class loadClass(String codebase,
                                 String name,
                                 ClassLoader defaultLoader)
            throws MalformedURLException,
                   ClassNotFoundException

loadClass

public static Class loadClass(URL codeBase,
                                 String name)
            throws MalformedURLException,
                   ClassNotFoundException
Loads a class from codeBase. This method delegates to RMIClassLoaderSpi.loadClass(String,String,ClassLoader) and passes codeBase.toString() as first argument, name as second argument and null as third argument.
Parameters:
codeBase - the code base from which to load the class
name - the name of the class
Returns:
the loaded class
Throws:
MalformedURLException - if the URL is not well formed
ClassNotFoundException - if the requested class cannot be found

loadProxyClass

public static Class loadProxyClass(String codeBase,
                                      String[] interfaces,
                                      ClassLoader defaultLoader)
            throws MalformedURLException,
