What are JavaBeans?

[GreyMan]

I've read a little bit about JavaBeans, but I'm still somewhat <br />
unclear as to what they actually are, and what they're used for.<br />
<br />
Can somebody explain to me what they are, and possibly provide an<br />
example?<br />
<br />
Thanks.<br />

javeBeans are reusuable Java classes that you can implement in your project. Wikipedia has a greate write up and example. Check it out.

Think of them like .dll in windows or .so in linux.

Javabeans are reusable software programs that you can develop and assemble easily to create sophisticated applications
They are used to encapsulate many objects into a single object (the bean), so that the bean can be passed around rather than the individual objects.

You could find example and a basic tutorial at this link

Today you could found more documentation in EJB subject.

EJB (enterprise java beans) from wikipedia
The EJB specification intends to provide a standard way to implement the back-end 'business' code typically found in enterprise applications (as opposed to 'front-end' user-interface code). Such code was frequently found to reproduce the same types of problems, and it was found that solutions to these problems are often repeatedly re-implemented by programmers. Enterprise Java Beans were intended to handle such common concerns as persistence, transactional integrity, and security in a standard way, leaving programmers free to concentrate on the particular problem at hand.

You grind them to make coffee. Which in turn helps you program all night long.
