Java note

Java byte code just like ASM. 

"CAFE BABE" is a joke in java byte code, which at the start of byte code.May be a joke.

Ant is a very powerful util to deploy our java program, I think I should learn it well.

Eclipse will not automatic deploy the referenced jar when you deploy a web project.Because the jar you have used may be an older version.
