How to intercept error request and redirect to a custom page?

An alternative way (and the way I have redirect 404 errors to a specific page in the community) is to override the 404. Jsp with a Hook. Then add your custom logic to the overridden JSP.

Add a JSP page to manage 404 errors as described here in that Liferay's forum post.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
