Examples of org.apache.xalan.xsltc.runtime.TransletLoader

org.apache.xalan.xsltc.runtime.TransletLoader
This class is intended used when the default Class.forName() method fails. This method will fail if XSLTC is installed in a jar-file under the $JAVA_HOME/jre/lib/ext directory. This is because the extensions class loader is used instead of the bootstrap class loader, and that the extensions class loader does not load classes for the default class path. But, if the extensions class loader is being used, then we know two things: (1) XSLTC is running on Java 1.2 or later (when extensions were introduced) (2) XSLTC has access to the ClassLoader.getSystemClassLoader() method This class takes advantage of this and uses a privileged call to this method to get a reference to the bootstrap class loader. It then uses this class loader to load the desired class. Note that this class should only be _instanciated_ if Class.forName() fails. And, YES, I do mean _instanciated_, and not called. By instanciating this class on Java 1.1 you'll get a NoSuchMethodException.
