JSF vs ASP.net

Posted by ryuzaki0 on from the caged-language-king-of-the-hill-match dept.

DuncanE asks: "We are looking at migrating an old legacy database application to a newer web based framework for the front end. For me the two obvious choices are ASP.net vs Java Server Faces. CodeGuru has side by side look at both, but does anyone have any real world comparisons? ASP.net appears to be MS only, which is a concern, depending on how mature mod_mono has become." Which framework would you prefer to use? Under what situations and conditions would you recommend the use of the other?

  1. JSF hard to develop by DeadSea · · Score: 3, Interesting
    I have a small project at work that I inherited that is written in JSF. It is a pain. Don't go there. I have problems with JSF:
    1. Non-existant error reporting: If an exception is throw by the code backing it up, the error message on the front end will be something like "Exception: '{mycomponent.dosomething}'". Which really means that dosomething threw some other exception that it is hiding from you.
    2. Everything is a post: JSF tries to apply MVC to the web, which is fundamentally broken IMO. The web is transactional, not event driven. To make it appear that everything has callbacks, all the links in the web app are done by making javascript submit a POST form for the page. Much harder to debug than any other web app that I've ever worked with. You can't just see the params on a GET url and expect links to work like every other link on the web
    I've never used ASP though, so I can't really compare. Myself I prefer servlets that spit out XML and use XSLT to give HTML. The designers don't seem to like the XSLT much though.
