I'm refactoring a JSP-only application and would like to move some of the code to servlets. For a bunch of tragic reasons, we are not able (right n...
I don't understand the nature of Java Beans that well. Well, at least how I see them used in some code-bases that pass through our shop. I found this question: http://stackoverflow.com/questions/315142/java-beans-what-am-i-missing The accepted answer there makes it look like programmers tend to abuse Java Bean (which I really don't do...

Inside my controllers, how do I go about loading a bean into either of these contexts? Note that I am aware of Getting Spring Applica...
What is the easiest way to retrieve a bean id from inside that bean (in the Java code) without using a BeanPostProcessor to set a field?

How do I pull a spring bean manually? I have a rather large web application, and in a given service, a transient object requires access to a bean that is machine specific (database connection info.) Since the application runs in a cluster, this transient object (which can bounce between servers) always needs to grab the correct connectio...

However, when I removed the getter and setter methods from an entity to have persistent fields, the values for the corresponding instance variable was not retrieved from the datab...

I'm wondering whether there is an existing Java class that, given a Java bean, uses introspection to find all the publicly modifiable fields, and displays them using default PropertyEditors. I see a bunch of information about BeanInfo, PropertyEditor, Bean Customizers, but nowhere can I find actual examples. Basically I want the functi...
