Hi again, >From what I found on the web, it's not safe to reuse the same instance of a Digester between different threads. But what I'm currently doing is creating a new instance of BeanReader (which extends the Digester class) for every call, which means that I shouldn't have any multithreading issue with the Digester lib. I will find more information about the lib's version and maybe send some code so you can tell me what is the problem.
