The closest stackoverflow question that explains my symptoms is here - How can I deploy a Grails 3.0.1 war file in Tomcat7?
I am in the process of upgrading a Grails 2.3.4 application to Grails 3.1.10 and everything is working with 'grails run-app'.
When i deploy to a war i get nothing but 404's for any url.
The war deploys without any error messages in catalina.out.
The tomcat access logs show my access attempts. (not linux problem?)
I can get to the tomcat manager, and the tomcat manager shows my app as "running" as true. (no errors)
Manager shows myapp-0.1 because the war file was myapp-0.1.war .. this is fine for now.
I am running Grails 3.1.10.
I have tried against Tomcat 7.0.55 as well as 8.0.92.
I have tried changing grails.serverUrl in application.groovy to various values. It is now:
//fix war name after get working
grails.serverUrl = "/myapp-0.1"
System.setProperty("server.contextPath","/myapp-0.1")
I have tried the above without "-0.1". (i was suprised to learn this was necessary - https://stackoverflow.com/a/23664531/104993)
I have tried changing "org.springframework.boo:spring-boot-starter-tomcat" from "compile" to "provided" in the build.gradle file.
Please let me know what I need to elaborate on. It's difficult to paste log outputs and config files. (i'm behind a firewall)
