通过nginx反向代理加载小程序

Question

我在 Tomcat 8 上托管了一个 Web 应用程序，用于提供小程序。当我通过 http 访问带有小程序的 HTML 页面时，它们工作正常。我已通过 nginx 反向代理进一步配置了 SSL。现在，当我尝试通过 https 访问相同的页面时，我得到了小程序的 ClassNotFoundException。我尝试谷歌搜索，但找不到明确的解决方案。可能出了什么问题？

编辑：我使用标签将小程序嵌入到 Login.html 中<applet>，该标签是托管在 Tomcat8 容器上的 angularjs Web 应用程序的一部分。小程序捆绑在 jar 文件中。小程序标签的 HTML 如下；

  <applet
        id="ABCobject"
        code="com.xxx.xxxxx.XXXXXApplet.class"
        archive="XXXXXApplet.jar"
    >
    </applet>

Nginx配置如下：

server {
listen 80;
server_name mxxx.xxxxxxx.in;
return 301 https://$host$request_uri;
}
server {
listen 443 ssl http2;
  listen [::]:443 ssl http2;
server_name mxxx.xxxxxxx.in;

root /var/www/html;

index index.html index.htm index.nginx-debian.html;

    ssl_certificate /etc/ssl/certs/__xxxxxxx_in.crt;
ssl_certificate_key /etc/ssl/private/wild-xxxxxxx-in.key;

ssl_protocols TLSv1.2 TLSv1.3;
ssl_prefer_server_ciphers on;
ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5;

add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";


access_log  /var/log/nginx/xxxx_access.log;
error_log  /var/log/nginx/xxxx_error.log;

location / {
   proxy_pass http://mxxx.xxxxxxx.in:8080/xxx-web-app-xxx/;
   proxy_buffering off;
   proxy_http_version 1.1;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header Upgrade $http_upgrade;
   proxy_set_header Connection $http_connection;
   proxy_cookie_path /web-appxxx/ /;
}

}

错误的堆栈跟踪是
