new geeky song about Java EE 5 (hosted on Javalobby).
It goes like this...
Ladies and gentlemen, this is Java EE 5!
One, two, three, four, five
There's a technology I use day and night
For my application with a web frontend
They told me to use .Net
But I really don´t wanna
So many bugs I fixed last week.
My code is neat and talk is a cheap
I like Glassfish, JSF, persistence API
And as I continue you know they´re gettin´ sweeter
So what can I do I really beg you my Lord
To me codin' it´s just like a sport
All the bad code from the past, let me dump it
Please set in the trumpet
A little bit of injection in my life
A little bit of persistence by my side
A little bit of NetBeans is all I need
A little bit of EJB's what I see
A little bit of standards in the sun
A little bit of XML all night long
A little bit web services here I am
A little bit of code makes me real man
This is Java EE 5!
Jump up and down and move your code around
Shake your head to the sound bury bad code under ground
Move one step left and one step right
One to the front and one to the side
Refactor it once and refactor it twice
If it looks like this you're doin´ it right
A little bit of injection in my life
A little bit of persistence by my side
A little bit of NetBeans is all I need
A little bit of EJB's is what I see
A little bit of standards in the sun
A little bit of XML all night long
A little bit web services here I am
A little bit of code makes me real man
This is Java EE 5!
Maybe I will grow up once. Maybe I won't...
