Sun Faces Util class methods and equivalents in MyFaces

[Andreas Niemeyer]

Hi,

I need to port some com.sun.faces.util.Util method calls to MyFaces 
equivalent methods.


The motivation is to implement an URLPermission tag for Liferay, based
on this article:

http://www.liferay.com/web/guest/community/forums?p_p_id=19&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&p_p_col_id=column-2&p_p_col_count=1&_19_struts_action=%2Fmessage_boards%2Fview_message&_19_messageId=531055&_19_threadView=tree


There are two custom classes (PermissionsLinkRenderer, 
PermissionsLinkTag) which are using the Util class and following methods:

Util.getExceptionMessageString(Util.NULL_PARAMETERS_ERROR_MESSAGE_ID));
Util.doAssert(writer != null);
Util.getValueBinding(_redirect)


Does there equivalent methods exist?


Kind regards,
Andreas
