can i put the form-login-page html in a library for a webapp?

I was trying to create an app with login page authentication. And for the same i added <form-login-page> into the web.xml (as shown below).

I jar'ed the logon.html and logonerror.html , and added them as a library along with the .war webapp file. (under WEB-INF/lib/logon.jar) .

But when I am deploying the app , am getting ERROR 404 , logon.html not found error. Any pointers to why ? Cant i keep the logon files (htmls,js,css files) in a library ?

Solution

My understanding is that a WAR will only expose the resources contained within its own root file structure. Hence the work-arounds (weblets, Maven config) mentioned in the answers to this question. You could make a custom build script that unpacked the content of logon.jar into your WAR, but I definitely wouldn't recommend that sort of hack. With a little more information concerning why you want to do this someone may be able to provide a better approach.
