Deployment fails when jboss-web.xml contains <enable-websockets>true</enable-websockets> ---------------------------------------------------------------------------------------- Key: WFLY-4725 URL: https://issues.jboss.org/browse/WFLY-4725 Project: WildFly Issue Type: Bug Components: Web (Undertow), Web Sockets Affects Versions: 10.0.0.Alpha2 Reporter: Radim Hatlapatka Assignee: Stuart Douglas Priority: Minor When deploying application with WebSockets used in EAP 6 to EAP 7, deployment will fail due EAP7 not supporting [1] in jboss-web.xml. The {{<enable-websockets>}} element is required in EAP 6 to enable the WebSockets functionality in JBoss Web. This element should be also allowed in EAP 7 in order to simplify migration from EAP 6. Functionality of {{ <enable-websockets>true</enable-websockets>}} can be ignored as in EAP 7 and in Undertow there is no need to enable WebSockets explicitly.
