我正在尝试将示例从Primefaces实施到WAB包中。

当我尝试访问JSF页面时，该页面为空。我在Glassfish日志文件中收到此错误：

我该如何解决这个问题？我想这可能是由POM配置引起的吗？
JSF / Facelets默认情况下已经使用UTF-8（在还原视图期间进行设置），但是PrimeFaces ajax视图处理程序会在还原视图之前尝试访问请求参数，因此将使用服务器的默认字符编码（ISO- 8859-1。您需要将以下条目添加到<glassfish-web-app>您的/WEB-INF/glassfish-web.xml文件，以指示GlassFish服务器使用UTF-8，以及：
<glassfish-web-app>
/WEB-INF/glassfish-web.xml
<parameter-encoding default-charset="UTF-8"/>
