本文介绍了一个通过系统类加载器强制加载预处理器实现的方法，确保预处理器实现在标准类路径中可用。具体步骤包括使用Class.forName方法加载指定的预处理器类，并创建其实例。
init
ClassPreProcessorHelper
public static synchronized void initializePreProcessor() {
// force loading thru System class loader to allow
// preprocessor implementation to be in standard classpath
s:org.codehaus.aspectwerkz.transform.AspectWerkzPreProcessor
Class klass = Class.forName(s, true, ClassLoader.getSystemClassLoader());
preProcessor = (ClassPreProcessor) klass.newInstance();
}
in my osgi framework must:klass = Class.forName(s);
