first off quercus is not 'the' implementation of php running on the jvm,
it's 'an' implementation.  ibm project 0 is another


and there may be more.  also, java is fast, but php applications can be made
fast as well, when it comes to serving web pages.  there are times when i
would consider implementing some domain logic in something like java for
speed, but for delivering applications on the web, php is very useful and
practical in terms of performance.

a lot of projects are mating their favorite language w/ the jvm which does
seem like a great idea, but one of the main drawbacks is the pace of feature
additions w/ the 'real' version of the project.  when i looked into quercus
a few years ago there wasn't support for things like spl and i'm not sure
where they stand w/ 5.3 features like closures and namespaces. not only that
but on any given minor release of php where is the parallel from quercus.
 also, the professional version of resin costs money.

these are probly the main reasons why the resin community isn't blowing up.
