What steps will reproduce the problem? 1. I used the sample code in my own project:

ContactListImporter importer=ContactListImporterFactory.guess(username, password); List<Contact> contacts=importer.getContactList(); for(Contact c : contacts) { out.println("name: "+c.getName()+", email: "+c.getEmail());

2. I input a gmail account.

What is the expected output? What do you see instead?

I got the contactlist of this gmail account,but I also got this exception in the server: 2008-5-28 14:35:01 com.xdatasystem.contactsimporter.ContactListImporterImpl getContactList 信息: Performing login 2008-05-28 14:35:02,609 [http-8080-2] [org.apache.http.client.protocol.ResponseProcessCookies] [WARN] [133] - Cookie rejected: "[version: 0][name: CAL][name: DQAAAHYAAACf8IJAYCByIJiO30jzqwz2e5z9t3GJlaojOhwvF_A8jeXjef7jG26K6ee7- NjdbKJMDxXuLOZ-q4lunCvZ6_whr0EGAYOhsrMBX9MZx- qlFoRfnVlzVK6p7HJm19YSGGI8jxLJBBhXnetMtCHnm7QXjk91j8ySap7eGsu_Kh_t9A] [domain: www.google.com][path: /calendar][expiry: null]".

The exception is harmless, it is outputted because the logging of HttpClient is turned on. You should be able to disable it, but you must do a complete build from source.
