i am doing a project which allows more than one person to access a servlet, which results in multiple servlet instances at the same time. and i think some objects may not be in a consistent way, they are servlet class variables, request attributes, session attributes and context attributes. is that right? do i need to synchronized these objects? thanks in advance

Yes, you can either synchronize any access to those variables, or implement the "SingleThreadModel" interface.
