| <div class="block">Provides static methods for loading classes using <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a> with optional verification that the codebase URIs | |
| used to load classes provide content integrity (see <a href="../../../net/jini/security/Security.html#verifyCodebaseIntegrity-java.lang.String-java.lang.ClassLoader-"><code>Security.verifyCodebaseIntegrity</code></a>). | |
| <p> | |
| Traditionally a class extending <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a> is determined by setting | |
| the system property "java.rmi.server.RMIClassLoaderSpi", or alternatively, | |
| <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a> may also be defined by <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoader.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoader</code></a> | |
| using a provider visible to the <a href="http://docs.oracle.com/javase/6/docs/api/java/lang/ClassLoader.html?is-external=true" title="class or interface in java.lang"><code>ClassLoader</code></a> returned by | |
| <a href="http://docs.oracle.com/javase/6/docs/api/java/lang/ClassLoader.html?is-external=true#getSystemClassLoader--" title="class or interface in java.lang"><code>ClassLoader.getSystemClassLoader()</code></a> with <a href="http://docs.oracle.com/javase/6/docs/api/java/util/ServiceLoader.html?is-external=true" title="class or interface in java.util"><code>ServiceLoader</code></a>. | |
| </p><p> | |
| As explained in River-336 this isn't always practical for IDE's or other | |
| frameworks. To solve River-336, ClassLoading now uses <a href="http://docs.oracle.com/javase/6/docs/api/java/util/ServiceLoader.html?is-external=true" title="class or interface in java.util"><code>ServiceLoader</code></a> | |
| to determine a <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a> provider, however unlike | |
| <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoader.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoader</code></a>, by default it uses ClassLoading's <a href="http://docs.oracle.com/javase/6/docs/api/java/lang/ClassLoader.html?is-external=true#getResources-java.lang.String-" title="class or interface in java.lang"><code>ClassLoader.getResources(java.lang.String)</code></a> | |
| instance to find providers. | |
| </p><p> | |
| To define a new RMIClassLoaderSpi for River to utilize, create a file in | |
| your providers jar file called: | |
| </p><p> | |
| META-INF/services/java.rmi.server.RMIClassLoaderSpi | |
| </p><p> | |
| This file should contain a single line with the fully qualified name of | |
| your RMIClassLoaderSpi implementation. | |
| </p><p> | |
| ClassLoading will iterate through all RMIClassLoaderSpi implementations found | |
| until it finds one defined by the system property: | |
| </p><p> | |
| System.getProperty("net.jini.loader.ClassLoading.provider"); | |
| </p><p> | |
| If this System property is not defined, ClassLoading will load | |
| <code>net.jini.loader.pref.PreferredClassProvider</code>, alternatively | |
| <code>java.rmi.server.RMIClassLoader</code> delegates all calls to <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoader.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoader</code></a>. | |
| </p><p> | |
| If a provider is not found, it will not be updated. | |
| </p><p> | |
| <h1>History</h1> | |
| <p>Gregg Wonderly originally reported River-336 and provided a patch | |
| containing a new CodebaseAccessClassLoader to replace <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoader.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoader</code></a>, | |
| later Sim Isjkes created RiverClassLoader that utilized ServiceLoader. | |
| Both implementations contained methods identical to <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a>, | |
| however new implementations were required to extend new provider | |
| implementations, creating a compatibility issue with existing implementations | |
| extending <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a>. For backward compatibility with existing | |
| implementations, <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a> has been retained as the provider, | |
| avoiding the need to recompile client code. The abilities of both | |
| implementations, to use ServiceLoader, or to define a provider using a method | |
| call have been retained, with the restriction that implementations are to be | |
| obtained via ServiceLoader. | |
| </p><p> | |
| Instead, all that is required for utilization of existing service provider | |
| <a href="http://docs.oracle.com/javase/6/docs/api/java/rmi/server/RMIClassLoaderSpi.html?is-external=true" title="class or interface in java.rmi.server"><code>RMIClassLoaderSpi</code></a> implementations is to set the system property | |
| "net.jini.loader.ClassLoading.provider". | |
