使用URLClassLoader加载weblogic.jar(Weblogic 12c服务器)

我尝试动态地将weblogic服务器(12.1.3)的weblogic.jar加载到类路径中,例如在运行时通过UrlClassloader。然后我想使用这个类加载器通过反射加载和启动emebedded weblogic服务器(原因是我们构建了自己的自定义测试运行器):

File file = new File("D:/Oracle/wls12130/wlserver/server/lib/weblogic.jar");
URL[] urls = new URL[]{file.toURI().toURL()};
URLClassLoader urlClassLoader = new URLClassLoader(urls, Thread.currentThread().getContextClassLoader());

Class<?> factoryClass = urlClassLoader.loadClass("weblogic.server.embed.EmbeddedServerFactory");
Class<?> serverClass = urlClassLoader.loadClass("weblogic.server.embed.EmbeddedServer");

Object factoryObject = factoryClass.newInstance();
Method factoryMethod = factoryClass.getDeclaredMethod("getEmbeddedServer");
Method serverMethod = serverClass.getDeclaredMethod("start");
Object server = factoryMethod.invoke(factoryObject);
serverMethod.invoke(server);

仅当我手动将weblogic.jar(通常位于weblogic服务器的server / lib&#39;目录中)添加到IDE(eclipse或intellij)中的类路径时,代码才有效。但是,它应该通过urlclassloader加载类而不将weblogic.jar作为IDE中的外部库加载,这给了我以下异常:

我在这里做错了什么?
