Google Custom API：java.lang.ClassNotFoundException错误

Question

我正在使用 here 中的Google Custom API示例。我的开发环境是： -

• Eclipse 3.4
• Java 1.7
• JSF 1.2 / Rich Faces 3.3
• Apache Tomcat 7.0.55

我添加了所有必需的jar（我假设这是因为我在eclipse中没有得到任何编译时错误）。快照是： -

编译后导入错误： -

import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.JsonFactory;
import com.google.api.client.json.jackson.JacksonFactory;
import com.google.api.services.customsearch.Customsearch;
import com.google.api.services.customsearch.model.Result;
import com.google.api.services.customsearch.model.Search;

当我运行应用程序时，我收到以下错误： -

我在这里缺少什么。为什么在编译时可用的文件在运行时错过了？
