Spring vs Pico container

[Pradeep bhatt]

How does Pico container compare with Spring ?

[Lasse Koskela]

PicoContainer is a component container, Spring is a component container and a lot more. Also, PicoContainer's implementation is somewhat trivial compared to Spring's.

Lasse, i understand that Spring is IOC + more. But any idea as to how the IOC part of the 2 containers compare? I mean are you saying that Pico does'nt support the different types of wiring Spring's BeanFacttory / Application context does? If yes, would it be possible for you to give an example?

Here's two examples:
(disclaimer: this is coming from what I read in "Spring in Action")

1) PicoContainer only supports programmatic configuration. In other words, you'd have to write your own bootstrapping class to register bean implementations with the container.

2) PicoContainer only supports one bean per class. In other words, if you want to configure two javax.sql.DataSources to your two databases, you're out of luck.

Pradeep,

The PicoContainer IoC capabilities are nowhere near as extensive as Springs. Spring is definitely the most complete and sophisticated IoC container on the Java market.

Thanks guys. I will get started with Spring soon.
