My old application with grails version 4.0.5 used to run perfectly. After being forced to update gradle I wasnt able to make it even compile. Then, I created a new project with grails 5.1.7, updated the build.gradle file with the new commands and finally it compiled. The application runs fine in my computer with:
grails run-app
However, when I make and run the .war file created with the command:
grails war
in my tomcat server, I get no errors on deployment, but http request always get an HTTP 404 error.
So I decided to make a new vanilla 5.1.7 grails project and try to make a new clean war. This new project also runs perfectly on my computer with run-app and also is deployed with no errors but also shows the HTTP 404 error with you try to retrieve a page.
I have been reading on grails documentation that grails war command makes a embedded container and could cause problems on tomcat:
https://docs.grails.org/latest/guide/deployment.html#deploymentStandalone
So, I tried to follow the advice and remove from build.gradle:
implementation "org.springframework.boot:spring-boot-starter-tomcat"
But still no luck, I keep getting the HTTP 404 error.
Summary:
My grails 4.0.5 application ran just fine creating the war file with "grails war", so I am not sure if this "embeddable" is the cause of the problem. Due to I get no errors I have no clue.
Any help would be appreciated
Machines and software I've tested:
Machine 1:
Machine 2:
Same result on both.
I have also tried to add:
ext['tomcat.version'] = '10.0.10' to gradle in case. Not working.
I managed to run the Grails 5 application on Tomcat 8 and Tomcat 9 by updating the JVM version from 11 to 16. It seems like Grails 5 doesnt support Tomcat 10.
