Having been exposed to both .NET and java i have to say i've prefered java. My main reasons are:
1. java is free so learning it as a student was cheaper (well, legally anyway!) 2. the amount of free stuff out there for java. There is soooooo much available! Show this to most .NET developers and they're amazed. Though to be truthful, show most .NET developers how much stuff is available for free for .NET and they're amazed! 3. Windows. if you go with .net, you have to use windows as a server. Firstly there's the whole security/stability issue. I'd agree that in my experience win2k server has been fairly stable. As for secure, that's a joke. How many worms have there been infecting windows servers? How many have infected *nix servers? It also seems madness to me to shell out so much for an operating system when there are better things for free. For example, I installed a linux server with a struts app on it about 6 months ago (uptime 161 days). Hasnt been restarted since. This was in a very large organisation that was 100% windows, and was dubious about my use of linux. Their IT manager i work with says she cant belive how stable it is, compared to all their windows servers. If MS launched .NET for linux, then i might reevaluate it. As for web services, i too love these. I especially love how easy it is to make a service using axis and .jws files. But i do have concerns about web services. Dont get me wrong, web services are great if you want to connect two systems which cant be connected in a simpler fashion. But i am concerned with the amount of overhead web services generate (refering to SOAP here as it is the prevelant standard). In a traditional message passing distributed system, the overhead (that soap introduces) could be controlled, by minimising the size of the messages. Instead of sending a couple of kilobytes of http headers and xml to ask for a record by id, you could just send the integer id number. Same applies to the response. Might not sound much but when you start processing thousands/millions of requests per second, the network bandwidth, processing power and memory usage required to handle these ineficient messages adds up. I would be interested to see a comparison of say mysql's native tcp communications, and say a SOAP+XML equivilent. The inefficiency of SOAP is also a big problem for mobile devices. Low memory (ram, and flash) prohibits the use of say axis+exerces. There are various solutions being tossed about.
