JSF应用在Eclipse、WildFly和 Jakarta Faces环境下无法运行

前端开发 2026-07-09

我找不到我的程序为何不工作的原因。我可以在带javax.faces 2.3.8的老版本Tomcat上让它工作。现在我尝试在最新版Eclipse 2026-03（配合JBoss Tools）、从Eclipse内部下载的WildFly 37.0.1服务器以及Jakarta Faces（WildFly的实现）环境中让它工作。没有额外的Java JDK/JRE，只有Eclipse自带的那个。我在Ubuntu 24.04.3桌面版上工作。

我创建了一个模板和一个index.xhtml页面，尝试使用我创建的UserBean。索引网页显示正常，但Bean无法工作。因此除了Bean信息不显示之外，一切看起来都正常。我还注意到在输入#{…} 数据时，没有任何帮助提示。

引用的库：PrimeFaces 15.0.15，但在此测试中并未使用。我也尝试过在不带PrimeFaces jar的情况下运行，问题仍然存在。

在服务器中我能看到一条警告：WARN [org.jboss.as.ee] (MSC service thread 1-6) WFLYEE0007: Not installing optional component org.jboss.weld.environment.servlet.Listener due to an exception (enable DEBUG log level to see the cause)。我已启用调试，但没有找到相关信息。

Eclipse配置：JavaServer Faces 2.3；由目标运行时提供的库。Java版本17。Dynamic Web Module（动态Web模块） 6.1。

The index.xhtml行

<p><h:outputLabel value="#{userbean.fullname}"/></p>

将转换为（在浏览器中查看页面源代码）

因此JSF可以工作，只有Bean无法工作。

在此先感谢，如果有谁能给我一个关于正在发生什么的思路。
