I'm trying to convert a service that runs on websphere 8.5 to open liberty. I'm getting the error below. How can I find more details on this? I'm assuming something in my web.xml is not supported in my list of features. Is that correct?
How can I find the web-fragment.xml file the error is referring to? There is no such file in my project, so I'm not clear what is on the line that is causing the issue.
CWWKC2262E: The server is unable to process the 4.0 version and the http://xmlns.jcp.org/xml/ns/javaee namespace in the /META-INF/web-fragment.xml
