Java库中的xpages，lotus。多米诺骨牌。会话类方法createDateTime（）引发NullPointerException

Question

当从XPage SSJS调用Domino Designer Java库文件夹中的Java文件（而不是Agents文件夹中的Java代理）时，对于createDateTime()之类的标准方法，会抛出NullPointerException：

import java.io.*;
import java.net.*;
import java.security.*;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.*;
import javax.faces.context.FacesContext;
import javax.net.ssl.HttpsURLConnection;
import com.ibm.commons.util.io.base64.Base64;
import lotus.domino.*;

public class Tools extends AgentBase  {

  ...

  public void getSession( ) throws IOException {

    Session s   = getSession();
    DateTime dt = s.createDateTime("Today");    // NullPointerException
    String n    = s.getEffectiveUserName();     // NullPointerException

    ...

  }

}

如果Java代码保存为Java代理，则不会引发异常

在Java中，有没有另一种方法可以不用session.createDateTime（）方法就用'Now'设置NotesDateTime字段

当使用Java库（不是代理）时，AgentBase是扩展的还是有其他扩展可供使用

还有什么其他方法可以创建lotus。多米诺骨牌。那会有帮助吗

更新：在插件中。xml，我添加了com。国际商用机器公司xsp。extlib作为一个依赖项，Java类编译时无错误

XPages属性，页面生成Xpage库com。国际商用机器公司xsp。extlib。已选中库

从服务器控制台，告诉http osgi ss com。国际商用机器公司xsp。extlib返回：

> tell http osgi ss com.ibm.xsp.extlib

请注意，日志显示正在启动com。国际商用机器公司xsp。extlib_9.0.1。v10_00_20180115-1058

这是什么意思？我还添加了一个updatesite。nsf文件发送到服务器并更新了注释。ini与OSGI_HTTP_DYNAMIC_BUNDLES=install\update site。nsf

启动HTTP时，没有消息表明OSGI正在加载到运行时

尝试设置会话时出现的错误：

NoClassDefFoundError:com/ibm/xsp/extlib/util/ExtLibUtil

这个类不是已经包含在Domino9.0.1FP10服务器中了吗
