The Java-Beanness of a POJO is that its public attributes are all accessed via getters and setters that conform to the JavaBeans conventions.

e.g.

private String foo;

public String getFoo(){...}

public void setFoo(String foo){...};

Additionally, true JavaBeans must implement Serializable and have a no-argument constructor.

POJOs don't have these restrictions.
