Read an article yesterday about the hot new start-ups and the technologies they are running on. I find that very few of them are on java, almost all of them are on LAMP. I am thinking of adopting PHP for yourmitra.com but not sure its worth the effort to learn up a new language at this moment. I know java and I am productive when I program in it.
I tried to find performance comparison between jsps and php but i could not come to any conclusion. I have to wait and see how yourmitra.com scales up with increasing volumes. I want to see it first hand before moving onto a new technology.
