This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
Hello, what happens to instance-level non-static variables declared in a Struts 1 actionclass? For example:
In this case, will the non-static object instances s and someList also be visible to all requests that simultaneously hit someAction? Because someAction is a singleton, my guess is even s and someList should also behave exactly like class-level (static) variables, and therefore should be accessible from simultaneous threads, causing concurrency issues.
