From the error log, it seems glass fish could not load the webApplication
class.
Make sure your webApplication class is in the correct class path
(com.example.helloworld.HelloWorldApplication)
And the webApplcation class is in the correct format.
or
and may change your web.xml file to be in this format:
<filter>
<filter-name>HelloWorldApplication</filter-name>
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
<init-param>
<param-name>applicationClassName</param-name>
<param-value>com.example.helloworld.HelloWorldApplication</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
</filter>
