Is Java suitable for "Web 2.0" applications?
I was chatting to someone the other day who suggested that Rails and PHP are the most suitable platforms for web applications, and to avoid Java. My background is mainly Java, and I know that it is considered by some to be too verbose and "heavyweight", but is used occasionally (eg by LinkedIn).
So I'm wondering whether anyone has had success using Java for a recent web application that has gone live, either using the language itself (eg with Stripes/Spring + Hibernate), or the runtime with a dymamic language (such as JRuby, Groovy, Jython)? If so, please share what worked and what you would do differently.
Some background (added later): Tim O'Reilly coined the phrased "Web 2.0" and here is his definition: http://www.oreillynet.com/lpt/a/6228
I think it's the "End of the release cycle" and "Lightweight programming model", involving rapid iterations and simplified deployment, where Java may be less suitable. Thoughts?
there are two totally different concepts called 'Web 2.0':
user generated content (usually with some 'social networking')
dynamic AJAX-based web apps
the second one somewhat dictates the technologies that you have to use (at least some JS, and machine-readable content in (some) responses). of course, there's nothing against using Java (or CGI, Perl, whatever) on the server.
the first one doesn't have anything to do with technology, and everything to do with the service itself you're providing. again, you can use anything you want.
why are these two mixed in the same therm? and more to your point: why are dynamic languages assumed 'more appropriate' for it? i'd guess it's just a temporal coincidence, all three things (user-generated content, AJAX, serious dynamic languages) jumped to the limelight roughly at the same time, and most of the proponents of each concept are using the other two.
in short, better avoid undefined marketroid terms like "web 2.0", and use proper descriptions. at least while working. when selling to the VCs and PHBs use any and all buzzwords that come near!
I would argue that there is no specific technology for Web 2.0. The main concept behind a Web 2.0 application is that much of the content is provided by it's users and not one specific person. If you can achieve this with Java, then that is fine. Many people are creating startup companies with technology that is free because they don't have the capital.
Of course it is. Java has some extremely mature and well tested frameworks for doing web applications, including so called Web 2.0 websites. Hibernate, Spring, even Struts and Tiles, or even Plain Old Servlets will do.
In addition, Java is very fast (see the Debian speed tests) compared to Ruby, which is good for websites handling lots and lots of requests, which Ajax does tend to inflate the number of! :)
