ReactJS difference between stateful and stateless

I am trying to understand the exact difference between React's stateful and stateless components. Ok, stateless components just do something, but remember nothing, while stateful components may do the same, but they remember stuff within this.state . That's the theory. But now, checking on how to show this using code, I have a little trouble making the difference. Am I right with the following two examples? The only difference really is the definition of the getInitialState function. Example of a stateless component: var React = require('react'); var Header = React.createClass({ render:

Using a Stateful Session Bean to track an user's session

不问归期 提交于 2019-11-27 06:46:08
it's my first question here and I hope that I'm doing it right. I need to work on a Java EE project, so, before starting, I'm trying to do something simple and see if I can do that. I'm stuck with Stateful Session Beans . Here's the question : How can I use a SFSB to track an user's session? All the examples that I saw, ended up in "putting" the SFSB into a HttpSession attribute. But I don't understand why! I mean, if the bean is STATEFUL, why do I have to use the HttpSession to keep it? Isn't an EJB Container's task to return the right SFSB to the client? I've tried with a simple counter bean

We currently have a Stateful bean that is injected into a Servlet. The problem is that sometimes we get a Caused by: javax.ejb.ConcurrentAccessException: SessionBean is executing another request. [session-key: 7d90c02200a81f-752fe1cd-1] when executing a method on the stateful bean. public class NewServlet extends HttpServlet { @EJB private ReportLocal reportBean; protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); try { String[]

Stateless vs Stateful - I could use some concrete information

I'm interested in articles which have some concrete information about stateless and stateful design in programming. I'm interested because I want to learn more about it, but I really can't find any good articles about it. I've read dozens of articles on the web which vaguely discuss the subject, or they're talking about web servers and sessions - which are also 'bout stateful vs stateless, but I'm interested in stateless vs stateful design of attributes in coding. Example: I've heard that BL-classes are stateless by design, entity classes (or atleast that's what I call them - like Person(id,

Why is it bad programming to use a stateful webservice and why would it be allowed?

问题 I have a need for a stateful webservice in our organization. However, everywhere I read online says that building a stateful webservice is bad programming but nothing ever says why. I guess I don't understand what is so bad about it. I also don't really understand why they would give a work around to allow you to have state in a webservice. So I guess that my question is, why is it bad programming to use a stateful webservice and why would it be allowed? 回答1: The whole purpose of a web

TensorFlow: Remember LSTM state for next batch (stateful LSTM)

问题 Given a trained LSTM model I want to perform inference for single timesteps, i.e. seq_length = 1 in the example below. After each timestep the internal LSTM (memory and hidden) states need to be remembered for the next \'batch\'. For the very beginning of the inference the internal LSTM states init_c, init_h are computed given the input. These are then stored in a LSTMStateTuple object which is passed to the LSTM. During training this state is updated every timestep. However for inference I
