What is a singleton? Q: What happens to singletons when two JVMs are running?

Code Style: Java language frequently asked questions (FAQ)
Whenever you need to represent quantities that have specific formatting and equivalence requirements, it is best to use the Quantity design pattern. For a Money type, you can associate a Currency with the amount and can deal with all rounding issues in one class. Your money and currency types can then use generic rendering methods to show the amount however you choose.

Design patterns Q: What is a singleton?

Code Style: Java language frequently asked questions (FAQ)
A singleton class is one in which instantiation is restricted to ensure that only one instance is created for the current Java Virtual Machine. Singletons usually have a private default constructor, to prevent direct instantiation, and a static method to obtain a "new" reference to the single instance. On its first call, the static instance method creates the object using a private constructor and stores a static reference to it for all subsequent calls.

Is there a way to synchronize UUIDs produced by JUG instance running on separate JVMs?

Java UUID Generator - FAQ
By default (and always with pre-2.0 Jug), Jug does not try to prevent multiple instances running from separate JVMs. The reason is that JVMs do not offer a generic mechanism for instances running on separate JVMs (or even via multiple class loaders!) to communicate easily. Starting with 2.0, there is a file-locking based synchronization mechanism that can be used to synchronize access, so that basically only one instance can ever run.

Are singleton/static objects shared between servlet contexts?

www.adobians.com
Question continues: For example if I have two contexts on a single web server, and each context uses a login servlet and the login servlet connects to a DB. The DB connection is managed by a singleton object. Do both contexts have their own instance of the DB singleton or does one instance get shared between the two?] The classes loaded from context's WEB-INF directory are not shared by other contexts, whereas classes loaded from CLASSPATH are shared.

How do you write a Thread-Safe Singleton?

Java Design Pattern Interview questions and FAQs
I have written plenty of non-thread-safe Singletons but it wasn't until recently when I tracked it down that I realized that thread-safety could be a big problem. The problem is that in the typical Singleton implementation (at least the ones I've seen) there is the ability to create multiple versions of the single instance...I know, "But How?". Well, in the getInstance() call the instance is checked for null, and then immediately constructed if it is null, and then the instance is returned.

Should the Dozer mapper be configured as a Singleton?

Dozer - faq
Yes. Mapper instance(s) should be setup as a Singleton. For every instance of the DozerBeanMapper, the mapping files are loaded and parsed.
