Singletons and cache

[karldmoore]

I guess it's useful to know a little about what you're doing here. If you only want one bean, it's going to be a singleton if you only one want person updating it make access synchronized, is there something I'm missing?

I am keeping track the number of processes running in an external system. We have a limit of processes that we can start and I am limiting that.

I will have a polling consumer that will update the number of processes running.

A message broker will need to have access to that information to determine if it can send a message that will start an external process.

I want to basically have one value in memory that can be updated.

BTW thanks for the help!

I don't think this has to be particularly complicated, all you need to do is synchronize access like you would normally.
