When I try to access the JSF page, the page is empty I received this error in the GlassFish log file:

How can I solve this problem? I think this may be caused by POM configuration?
Solution
JSF / facelets uses UTF-8 by default, which has been set when restoring the view, but the primefaces Ajax view handler attempts to access the request parameters before restoring the view, so it will use the server's default character encoding instead of ISO - 8859-1 You need to add the following entries to < GlassFish web app > your / WEB-INF / GlassFish web XML file to indicate that the GlassFish server also uses UTF-8:
<parameter-encoding default-charset="UTF-8"/>
You can also see:
