Spring Boot Websockets in Wildfly

Question

Hi I need to deploy my Spring Boot app into Wildfly 8.1 and I\'m getting the following exception:

Caused by: java.lang.RuntimeException: java.lang.Cl

Answer 1

spring-boot-starter-web and spring-boot-starter-websocket by default includes the spring-boot-starter-tomcat so exclude the tomcat, like below

     
        org.springframework.boot
        spring-boot-starter-web
        ${spring-boot.version}
        
            
                org.springframework.boot
                spring-boot-starter-tomcat
            
        
    

     
        org.springframework.boot
        spring-boot-starter-websocket
        ${spring-boot.version}
        
            
                org.springframework.boot
                spring-boot-starter-tomcat
            
        
    

and include undertow, make sure the tomcat exists no where in the classpath.
