Error while deploying in Tomcat container

Questions
1

First, I build a WAR file from servoy platform by following this step

757×578 31.8 KB

Then, I start up a Tomcat container by executing

docker container run -it -d --name tomcat -p 8081:8080 tomcat:jre17-temurin

I copied the WAR file from the host to the container by executing

docker cp my_war_file.war tomcat:/usr/local/tomcat/webapps

Unfortunately, it is not successful and I got the error in log file

How can I overcome this issue?

What is the version of tomcat you are running on that docker instance?

I know a combination of tomcat v9 and java 17 should run fine.

can you have a good look at your install? like application_server\lib and/or \drivers?

do you have there somewhere a 0 byte jar? please remove that.

you can also test the WAR itself so look inside and into WEB-INF/lib to see if you have a 0 bytes jar there
