現在我使用以下內容：NetBeans 8.2阿帕奇湯姆貓 8.0.53JSF 2.2冰面 4.3全部在 Maven 項目中（我認為是 3.6）我試圖用我已經創建的列表填充“ace：dataTable”。當我嘗試在沒有 ace:dataTable 的情況下運行“Principal.xhtml”時，頁面加載正常，但是如果我添加帶有我想要填充的值的 ace:dataTable，它會顯示錯誤“HTTP 500 – 內部服務器錯誤”例外“javax.servlet.ServletException：javax/enterprise/context/spi/Contextual javax.faces.webapp.FacesServlet.service(FacesServlet.java:683) org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter .java:52)"這是我在 pom.xml 中使用的依賴項 <dependency> <groupId>org.icefaces</groupId> <artifactId>icefaces</artifactId> <version>4.3.0</version> </dependency> <dependency> <groupId>org.icefaces</groupId> <artifactId>icefaces-ace</artifactId> <version>4.3.0</version> </dependency> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>7.0</version> <scope>provided</scope> </dependency>這也是我在 XHTML 中使用的代碼<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:icecore="http://www.icefaces.org/icefaces/core" xmlns:ace="http://www.icefaces.org/icefaces/components"> <h:head> <title>List Test</title> </h:head> <h:body> <ace:dataTable id="test" value="#{personaController.listaPersona}" rows="5" var="item" paginator="true" styleClass="textTabla" paginatorPosition="bottom"> <ace:column> <f:facet name="header"> <h:outputText value="SOLICITUD" styleClass="textTablaCabeza" /> </f:facet> <h:outputText value="#{item.nombre}" styleClass="textTablaDetalle" /> </ace:column> </ace:dataTable> </h:body> </html>

看起來您在 pom 中缺少 cdi-api 所需的依賴項：
<dependency>
<groupId>javax.enterprise</groupId>
<artifactId>cdi-api</artifactId>
<version>1.2</version>
</dependency>
