How to upgrade the newer tomcat version 9.0.31

OS:cetnos7.7+docker19.03

tomcat version：9.0.31，ghostscript-9.51,ImageMagick7.0.10.1,sox-14.4.2.tar.bz2

kurento in docker:

docker run -d --name kms -p 8888:8888 --mount type=bind,source=/opt/apache-openmeetings-5.0.0-M3/webapps/openmeetings/data,target=/opt/apache-openmeetings-5.0.0-M3/webapps/openmeetings/data kurento/kurento-media-server

+stun/turn server(behind NAT)

docker(kms)—>turnserver(3478 to internet )&openmeeting5.0.0M3 --->FireWall—>internet--FireWall--->client

I copied tomcat9.0.31 to Related directories,and ran,and many functions can be implemented,

a few probrelems:below:

 very Small files can be uploaded,like txtfile,doc file...,big files even like pptx can not be uploaded,it seemed that the probrelm came from  Fileup1.4.jar.
