Class RMIClassLoader

java.lang.Object

java.rmi.server.RMIClassLoader

public class RMIClassLoader
extends java.lang.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

                                           java.lang.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:

java.net.MalformedURLException - if the URL is not well formed

java.lang.ClassNotFoundException - if the requested class cannot be found

                                            throws java.net.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:

java.net.MalformedURLException - if the codebase contains a malformed URL

getClassAnnotation

public static java.lang.String getClassAnnotation(java.lang.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
