所以我的问题是，我想使用javafx2.2.5的WebView的两个实例在不同的容器（JFrame的）同时进行。
我发现这个技巧允许在不同的线程中使用不同的cookiestores。 如何利用HttpURLConnection类和CookieManager在Java中使用不同的Cookie为每个连接我不能让它工作，似乎WebView中创建多个线程加载一个页面，而这个线程请求默认的cookie处理程序，所以我结束了20不同cookiestores（InMemoryStore）。这代码为洛到易趣JavaFX中网页视图自动。
因此，所有的代码，我使用这个：
public class MySessionManager extends CookieHandler{
private final static MySessionManager ms_instance = new MySessionManager();
public static MySessionManager getInstance(){
return ms_instance;
}
private final static ThreadLocal<CookieStore> ms_cookieJars = new ThreadLocal<CookieStore>() {
@Override
protected synchronized CookieStore initialValue() { return new InMemoryStore(); }
};

{
getCookieStore().removeAll();
}
public CookieStore getCookieStore() {
return ms_cookieJars.get();
}

this(null, null);
}
public MySessionManager(CookieStore store,CookiePolicy cookiePolicy) {
// use default cookie policy if not specify one
policyCallback = (cookiePolicy == null) ? CookiePolicy.ACCEPT_ORIGINAL_SERVER
: cookiePolicy;
// if not specify CookieStore to use, use default one
}
