URL Mapping

[Senthoor]

Guys,   We have a small requirement to paly the the URL....   Basically there is a domain for example www.xyz.com   and when someone types www.xyz.com/UserName (Username can be any user in the Database) it should take him to a custom page which is customised for that particular user. So I would go and type www.xyz.com/senthoor.   The problem is normally it throws a 404 since this /senthoor is not mapped and what we did was we cought the 404 and re-directed to a JSP and captured the URL extracted the "UserName" validated against the DB and loaded the custom page....   But this worked as specified in WebLogic but when we ported it to Oracle Application Server it give a 500 error.   I would like to know whether there exist any other solution for this except capturing 404s and 500s. Basically since the username is growning in the Database with members signing in we can't have servelet mapping to handle this too...   Senthoor
