I'm trying to connect to my http://localhost: 8080/spring-boot-test/ui, but unfortunately I fail because I have errors on Eclips. WildFly 23 theoretically worked, because I normally get their localhost
An internal error occurred during: "Updating Deployment Scanners for Server: WildFly 23".
Could not initialize class org.wildfly.security.auth.client.DefaultAuthenticationContextProvider

When I try to redirect the directory in standalone.xml to a target with META-INF and WEB-INF, I come across two ERRORs
ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) WFLYDS0011: The deployment scanner found a directory named META-INF that was not inside a directory whose name ends with .ear, .jar, .rar, .sar or .war. This is likely the result of unzipping an archive directly inside the C:\Users\adame\eclipse-workspace\spring-boot-test\target directory, which is a user error. The META-INF directory will not be scanned for deployments, but it is possible that the scanner may find other files from the unzipped archive and attempt to deploy them, leading to errors.
