问题描述
我正在尝试将Primefaces中的示例实现为WAB包。
I'm trying to implement example from Primefaces into WAB package.

当我尝试访问JSF页面时，页面是空。我在Glassfish日志文件中收到此错误：
When I try to access the JSF page the page is empty. I get this error in Glassfish log file:

我如何解决这个问题？我想这可能是由POM配置引起的？
How I can fix this problem? I suppose that this maybe caused by POM configuration?
推荐答案
JSF / Facelets默认使用UTF-8已经在恢复过程中设置了视图，但是PrimeFaces ajax视图处理程序在视图恢复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，而不是ISO-8859-1。您需要将以下条目添加到 /WEB-INF/glassfish-web.xml的文件，指示Glassfish服务器也使用UTF-8：< glassfish-web-app> 中
JSF/Facelets uses UTF-8 by default already which get set during restoring the view, however the PrimeFaces ajax view handler tries to access a request parameter before the view get restored, so the server's default character encoding will be used instead which is ISO-8859-1. You need to add the following entry to the <glassfish-web-app> of your /WEB-INF/glassfish-web.xml file to instruct the Glassfish server to use UTF-8 as well:
<parameter-encoding default-charset="UTF-8"/>
参见：
- 通过PrimeFaces输入组件检索到的Unicode输入已损坏
- Unicode input retrieved via PrimeFaces input components become corrupted
