Hi Felipe, I'm not a TomEE guy - or even much of a JAX-WS guy, so take my advice with a grain of salt...
I have seen problems like that in WebSphere and OpenLiberty - and that usually happens when the application archive(s) package the same jars as the runtime. For example, I know that TomEE packages some CXF modules (as WebSphere and Liberty does) - and so if a user packaged those same CXF module jars in their application, then it is likely that they would see these ClassCastExceptions since the classes are loaded from different class loaders. I would start by checking your application archives (WARs/EARs/etc.) to see if it packages CXF. If so, you may need to use the <scope>provided<scope> line in your pom.xml to avoid pulling in CXF jars. Then you would use the CXF modules that are provided by TomEE - and there should no longer be any conflict. Hope this helps, Andy On Wed, Nov 27, 2019 at 12:57 PM Felipe Jaekel <fkjae...@gmail.com> wrote: > Hi, > > I have a Spring Boot (2.2.1) app that uses CXF for SOAP contract last web > services.
