我的RCP對ClassLoad問題的解決，這是一個讀jndi配置文件的方法。

    private void intJNDI() {
        ClassLoader cl = Thread.currentThread().getContextClassLoader(); //保存老的ClassLoader
        Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader()); //設置新的ClassLoader
        IPath path = new Path("properties/jndi.properties");
        URL url = AdminConsolePlugin.getDefault().find(path);
        Properties p = new Properties();
        try {
            p.load(url.openStream());
            String address = System.getProperty("jndi.address");
            String port = System.getProperty("jndi.port");
            if (address != null && !address.trim().equals("") && port != null && !port.trim().equals("")) {
                p.remove("java.naming.provider.url");
                p.setProperty("java.naming.provider.url", "jnp://" + address.trim() + ":" + port.trim());
            }
            AdminConsolePlugin.getDefault().setJNDIInitContext(new InitialContext(p));
        } catch (Throwable e) {
            throw new RuntimeException("Failed to connect to domain controller.", e);
        } finally {
            Thread.currentThread().setContextClassLoader(cl);//最后恢復成老的ClassLoader
        }
    }
