----------------------------------------
Summary: Struts 2 fails to init Dispatcher - Tomcat Embedded
Key: WW-4902
URL: https://issues.apache.org/jira/browse/WW-4902
Project: Struts 2
Issue Type: Bug
Components: Core
Affects Versions: 2.3.34
Reporter: George Felix Barbosa
I'm migrating a webapp from Jboss 7.1.1 to tomcat embedded 8.5.14. It works
fine while I run it on Intellij but when I try to create an executable war file
Struts fails to start.
I have been using struts2-core:2.3.34, xwork-core:2.3.34 and
struts2-spring-plugin:2.3.34.
Tomcat embedded starts normal and everything looks good but when I call a page,
struts try to start the dispatcher and it fails. I've created a small project
to reproduce that error and it can found
[https://github.com/GeorgeBarbosa/spring-boot-struts2].
In addiction, there are no duplicate jars in my classpath.
Please, is it a error in Struts or something else? What should I do to get
struts2 working in tomcat embedded?
