As quoted in: Servlet Action Description

Servlet Action Context is a sub class of Action Context.

"ServletActionContext is Web-specific context information for actions".This class adds access to web objects like servlet parameters, request attributes and things like the HTTP session. In simple terms one can say Action Context is generic while the servlet action context is more specific in terms of its usage

For Example: GenericServlet and HttpServlet; GenericServlet is for servlets that might not use HTTP, like for instance FTP servlets etc. while HttpServlet is more specific.

They don't work the same; one has web-app-specific functionality.

XWork is not a web app framework--hence the ActionContext. WebWork/Struts 2 added web-specific functionality, hence ServletActionContext, which is a subclass of ActionContext, and adds web-related stuff.
