I have an application which really should be installed, but does work fine when deployed using JNLP.

So my question is, how do I detect a...

Hi there, The system I am currently working on requires some role-based security, which is well catered for in the Java EE stack. The system intends to be a framework for business domain experts to write their code on top of. However, there is also a requirement for data 'security'. That is, what information is visible to an end user. ...
I have a recursive algorithm which steps through a string, character by character, and parses it to create a tree-like structure. I want to be able to keep track of the character index the parser is currently at (for error messages as much as anything else) but am not keen on implementing something like a tuple to handle multiple return...

In C++ when a virtual function is called from within a constructor it doesn't behave like a virtual function. I think everyone who encountered for the first time was surprised but on second thought it makes sense, if the derived constructor hasn't yet run the object is not yet a derived so how can a derived function be called?
