I have tested this springbbot app in my pc (localhost) it is working fine but not on tommy server

What version of Tomcat and java are you running on your pc?

[J823]

inside my computer

 

tomcat 9.0.40

java 1.8

 

in pom.xml

it is using its own embedded tomcat and jre(1.8)

 

and while printing java version in my pc spring tool suit using

 

System.getProperty("java.version")

 

it is returning me

 

15 as output

Try installing and testing your .war on Tomcat 8.5.24 because that is what Tommy is currently running.

 

Also, you might be interested to know that I work on threads from oldest to newest, so each time you bump your thread you move it to the bottom of my todo list.

Spring boot was running its own tomcat server

(which is useful for standalone web application or running springboot webapp with the help of cli)

 

but here we already have a heliohost tomcat server(8.5.24) (for deploying war file)

 

which is conflicting with spring boots embedded server

 

( because of spring boot latest embedded tomcat "v 9.0 something" )

 

so on heliohost i have to deploy spring boot war file on external tomcat(heliohost tomcat )

 

for doing this i followed this guys utube video

 

 

 

 

Thankyou @krydos ❤️
