Hi, I faced some similar problems a few months ago. I configured the alternatedocroot in my sun-web.xml.
My problem was because of the directories. Do u have a directory "assets" inside your "J:/inetpub/wwwroot/prototype/".
I wanted to server content from [i]C:\WebServer\glassfish\domains\domain1\fileUploaded\[/i] accesed via [i]/docs/*[/i] so my alternatedocroot looks like:
<property name="alternatedocroot_1" value="from=/docs/* dir=c:\WebServer\glassfish\domains\domain1\fileUploaded\" />
And my path has a "docs" directory inside "C:\WebServer\glassfish\domains\domain1\fileUploaded\". That's the only way that I did it work. Hope it can help u.
