我升級JSF 2.2到JSF 2.3，
使用wildfly 11.0.0測試版作爲服務器。<f:websocket>標籤庫支持的命名空間：http://xmlns.jcp.org/jsf/core，但沒有標籤被用於名定義：WebSocket的
我按照本網站上的說明。 http://arjan-tijms.omnifaces.org/p/jsf-23.html#1396
服務器啓動良好，應用程序正常工作。 當我打電話的push.xhtml（測試新的WebSocket集成），
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:p="http://primefaces.org/ui"
>
<h:body>
<h:form id="form">
<p:growl autoUpdate="true" id="growl" showDetail="true" />
<div class="ui-g dashboard">
<p:panel id="musteriHafiza">
<div class="ui-g-12 ui-md-6 ui-lg-6 task-list">
<p:commandButton value="CLOCK PUSH" action="#{applicationBean.clockAction()}"></p:commandButton>
</div>
<f:websocket channel="clock" onmessage="socketListener"/>
<br />
<div id="clockId"></div>
</p:panel>
</div>
</h:form>
<script type="text/javascript">
function socketListener(message, channel, event) {
document.getElementById("clockId").innerHTML += message + "<br/>";
}
</script>
</h:body>
</html>
我得到這個錯誤：

有什麼建議？
它是關於標記庫xmlns：f =「http://xmlns.jcp.org/jsf/core」？
檢查日誌，看2.3是否真的被加載，而不是仍然2.2 – Kukeltje
好吧，我從日誌中發現2.3沒有加載。謝謝。 – CSekem
使用了一些與Wildfly相關的主題：在Payara/Glassfish下，我有時必須刪除'〜/ personal_domain/osgi_cache /'來讓應用程序服務器重建它，因爲它可能會導致干擾。也許在Wildfly中存在類似的東西？ – Roland
