Struts2 won't make your custom class threadsafe unless your code is
threadsafe, synchronized(this) or synchronized method can be used in your
service implementation if you think your service class is not threadsafe.
Usually Service or DAO layer should be written threadsafe, don't know about
your DAO or Service is threadsafe to make a clear comment on it. Action
classes are thread safe since it creates new instance per request.
