    Notes on Collections
	
    By default, Scala uses immutable collections. However, there are mutable

Enable Remote Debugging on a Java Server

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5001

The best documentation on this is available from InformIT. This site details the following parameters:

• -Xdebug : Enables the application to be debugged.
• -Xnoagent : Disables the sun.tools.debug agent so that the JPDA debugger can properly attach its own agent.
• -Djava.compiler=NONE : Disables the JIT (Just-In-Time) compiler.
• -Xrunjdwp : Loads the reference implementation of the Java Debug Wire Protocol, which enables remote debugging.

Immutable vs. Mutable Objects

Advantages of Immutable

• There is no way for multiple threads to concurrently mutate or access an immutable value as no thread can change an immutable object.
• When passing a value into foreign code, one can be assured that an immutable value will not change.
• There are fewer concerns - immutable objects cannot have complex states that change over time.

Disadvantages of Immutable

• When an object is quite large, it is inefficient to update the full object graph. In some cases, it is best to do an in-place modification.

JSF and RichFaces Notes

Validators:

<!-- Combination of rich:beanValidator and a4j:support. This will bind to the hibernate validators for the model and
     validate when the field is no longer in focus (onblur). The event could be any supported event.
-->
<rich:ajaxValidator event="onblur" />
