Class RMIClassLoader

java.lang.Object

java.rmi.server.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

                                 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

getClassLoader

                                  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

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

getSecurityContext

public static Object getSecurityContext(ClassLoader loader)

Deprecated.

getDefaultProviderInstance

public static RMIClassLoaderSpi getDefaultProviderInstance()

Returns the default service provider for RMIClassLoader.

Returns:

the default provider for RMIClassLoader
