在Java Web应用程序中启用NTLM后出现错误-Ubuntu 18.04

Question

我创建了一个Java Web应用程序并托管在Ubuntu 18.04中的tomcat 9.0上，我想在我的Java Web应用程序中启用NTLM，因为我已经使用NTLM Http过滤器编辑了web.xml文件。当我浏览网页时，它要求我输入用户名和密码，在输入用户名和密码并单击“确定”后，将导致出现以下错误，HTTP状态为500

Web.xml NTLM过滤器

<filter>
  <filter-name>NtlmHttpFilter</filter-name>
  <filter-class>jcifs.http.NtlmHttpFilter</filter-class>

   <init-param>
  <param-name>jcifs.http.domainController</param-name>
  <param-value>192.168.1.100</param-value>
  </init-param>
  </filter>
  <filter-mapping>
<filter-name>NtlmHttpFilter</filter-name>
<servlet-name>ViewerServlet</servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name>NtlmHttpFilter</filter-name>
<servlet-name>EngineServlet</servlet-name>

  </filter-mapping>

<init-param>
<param-name>jcifs.smb.client.username</param-name>
<param-value>Admin</param-value>
</init-param>
<init-param>
<param-name>jcifs.smb.client.password</param-name>
<param-value>Admin</param-value>
</init-param>

错误：
