WildFly 21 - No routing provider found for default-server; using legacy provider based on static configuration

Question

I got this warning while I run wildFly server

16:54:56,327 WARN  [org.wildfly.clustering.web.undertow] (ServerService Thread Pool -- 77) WFLYCLWEBUT0007: No routing provider found for default-server; using legacy provider based on static configuration

Answer 1

To get rid of this warining, you have to add the following entries to your Wildfly standalone.xml:

Add the org.wildfly.extension.clustering.web extension inside the <extensions> tag

<extension module="org.wildfly.extension.clustering.web"/>

Add the <distributable-web> subsystem inside the <profile> tag

Wildfly 21:

    <subsystem xmlns="urn:jboss:domain:distributable-web:2.0" default-session-management="default" default-single-sign-on-management="default">
        <infinispan-session-management name="default" cache-container="web" granularity="SESSION">
            <primary-owner-affinity/>
        </infinispan-session-management>
        <infinispan-single-sign-on-management name="default" cache-container="web" cache="sso"/>
        <infinispan-routing cache-container="web" cache="routing"/>
    </subsystem>

Wildfly 23 and 26:

    <subsystem xmlns="urn:jboss:domain:distributable-web:2.0" default-session-management="default" default-single-sign-on-management="default">
        <infinispan-session-management name="default" cache-container="web" granularity="SESSION">
            <local-affinity/>
        </infinispan-session-management>
        <infinispan-single-sign-on-management name="default" cache-container="web" cache="sso"/>
        <local-routing/>
    </subsystem>
