java - Spring Rest- result page does not display results instead requested resource is not available -

-

i don't know if i'm doing correctly i'm using spring , creating rest client-server. index.jsp displays form user enters information dog, , click submit , should go result page should displays result (so they've entered). problem when user fills out form , clicks submit error "requested resource not available". can tell me going wrong, why welcome.jsp page create error?

index.jsp (contains form)

<body>      <form action="welcome.jsp" th:action="@{/dog}" th:object="${dog}" method="post">         <p>id: <input type="text" th:field="*{id}" /></p>         <p>name: <input type="text" th:field="*{name}" /></p>         <p>heartbeat: <input type="text" th:field="*{heartbeat}" /></p>         <p>temperature: <input type="text" th:field="*{temperature}" /></p>         <p>lat: <input type="text" th:field="*{lat}" /></p>         <p>long: <input type="text" th:field="*{lon}" /></p>         <p>weight: <input type="text" th:field="*{weight}" /></p>         <p><input type="submit" value="submit" /> <input type="reset" value="reset" /></p>     </form>  </body>

welcome.jsp (should display result of user entered) 

<body>   <h1>result</h1>     <p th:text="'id: ' + ${dog.id}" />     <p th:text="'content: ' + ${dog.name}" />     <a href="index.jsp">submit message</a> </body>

dogcontroller-get post request

@restcontroller @requestmapping("/dog") public class dogcontroller {      private static final string template = "hello, %s!";     private final atomiclong counter = new atomiclong();      @requestmapping(value="", method = requestmethod.get)     public createdog greeting() {         return new createdog(counter.incrementandget(),"dog", 40, 25, 120, 71.0486,114.0708);     }      @requestmapping(value="", method = requestmethod.post)     public string createdog(@modelattribute createdog dog, model model) {         model.addattribute(dog);         return "result";     } }

i'm not sure what's th:action for. seems have 2 actions tag in page, right?

you can try visit url browser directly , see if can result.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
