Not sure what is going wrong....

you should run the maven goal `spring-boot:run` to start a embedded application server that serves your spring boot application — Goos van den Bekerom, Sep 20 '18 at 14:30
That's not what the reporter is asking, `mvn spring-boot:run` has nothing to do with deploying an app in TomEE. — Stephane Nicoll, Sep 21 '18 at 08:51
@JagadheeswaranMohan you have incompatible Hibernate validators API on the classpath. TomEE ships with an older release that takes precedence. I don't know off the top of my head how to tell TomEE to stop doing that but their documentation should help you. — Stephane Nicoll, Sep 21 '18 at 08:54
@StephaneNicoll thanks for the path provided. Went through [this] http://tomee.apache.org/tomee-and-hibernate.html documentation, is there anything better which explains the fix. — Jagadheeswaran Mohan, Sep 21 '18 at 09:25
Can you provide a MWE via github? Others can then better help by debugging and checking the project setup. — MWiesner, Dec 01 '18 at 10:20

We had a similar issue deploying a Spring Boot application as a war into a TomEE 7.1.0. container, and we resolved it with an entry in the META-INF/context.xml for the application war.

<?xml version='1.0' encoding='utf-8'?>
<Context path="/app/service">
  <Loader delegate="true"/>
</Context>

https://tomcat.apache.org/tomcat-8.0-doc/config/loader.html

attribute = delegate

Set to true if you want the class loader to follow the standard Java2 delegation model, and attempt to load classes from parent class loaders before looking inside the web application. Set to false (the default) to have the class loader look inside the web application first, before asking parent class loaders to find requested classes or resources.

https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

Therefore, from the perspective of a web application, class or resource loading looks in the following repositories, in this order:

Bootstrap classes of your JVM

/WEB-INF/classes of your web application

/WEB-INF/lib/*.jar of your web application

System class loader classes

Common class loader classes

If the web application class loader is configured with <Loader delegate="true"/> then the order becomes:

Bootstrap classes of your JVM

System class loader classes

Common class loader classes

/WEB-INF/classes of your web application

/WEB-INF/lib/*.jar of your web application

Thanks for the solution, will try the approach and will accept it. — Jagadheeswaran Mohan, Apr 24 '19 at 08:58
