在Java库中,lotus.domino.Session类方法createDateTime()抛出NullPointerException

lotus lotus-domino xpages java

teleman · 技术社区 · 6 年前

当从XPage SSJS调用Domino Designer Java library文件夹中的Java文件(而不是Agents文件夹中的Java代理)时,对于标准方法(如 createDateTime() :

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

    ...

  }

}

有没有其他方法可以在Java中用'Now'设置NotesDateTime字段,而不必使用session.createDateTime()方法?

AgentBase是扩展的还是在使用Java库(不是代理)时要使用另一个扩展?

还有哪些其他方法可以帮助创建lotus.domino.Session?

更新: 在 ,我补充道 com.ibm.xsp.extlib 附属国 ,并且编译的Java类没有错误。

,页生成Xpage库 com.ibm.xsp.extlib.library库

注意日志上写着

那是什么意思?我还向服务器添加了updatesite.nsf文件,并用 OSGI\u HTTP\u DYNAMIC\u BUNDLES=install\update-site.nsf .

启动HTTP时,没有任何消息表明OSGI正在加载到运行时。

尝试设置会话时出现的错误:

Domino9.0.1FP10服务器中是否已经包含了此类?

获取会话

Session s = ExtLibUtil.getCurrentSession();

随后的代码行将工作。

public class Tools  {
  ...
  public void yourMethod() {
    Session s   = ExtLibUtil.getCurrentSession();
    DateTime dt = s.createDateTime("Today");
    String n    = s.getEffectiveUserName();
    ...
  }
}

getSession() 您只对Java代理使用works。
