Spring MVC how to load a js from a jsp

Question

I work with Spring MVC. I have a dynamic web project Eclipse

Structure folder is

I have the following jsp actualizarCorreo.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<!DOCTYPE html>
<html>
<head>
<title>EusurveyAdmin menu princiapl</title>

<script type="text/javascript" src="/resources/js/properties.js"></script>

<script type="text/javascript">
function pruebaB()
{
   alert('en prueba');
}
</script>
</head>
<body>
    <c:set var="pageNumber" value="${pageNumber}" />
    <table class="actualizarCorreos">

        <tbody>
        <a href="#" onclick="prueba()"; return false;">
            <input type="radio" onclick="prueba()" class="check" id="id1"
                name="id1" value="true" />
            <spring:message code="label.ModificarCorreos" />



        </tbody>
    </table>

</body>

In this jsp I load another js

<script type="text/javascript" src="/resources/js/properties.js">

This js is the path WebContent/resources/js.

properties.js is

alert('cargado properties');
function checkConfirmationPage()
{       
    alert('en check');
    if ($("#conflink").is(":checked"))
    {} else {};
}

function prueba()
{
    alert('en prueba');
}

I call function prueba from actualizarCorreo.jsp when a radio button is clicked

<input type="radio" onclick="prueba()" class="check" id="id1"
                name="id1" value="true" />
            <spring:message code="label.ModificarCorreos" />

I don't see the alert message function prueba.

What is it wrong?

Try this

 <script type="text/javascript" src="../resources/js/properties.js"></script>

or use the below as reference and find the exact path:

   /   = Root directory
   .   = This location
   ..  = Up a directory
   ./  = Current directory
   ../ = Parent of current directory
   ../../ = Two directories backwards

Or directly get the context path to fetch the .js

<script type="text/javascript" src="<%=request.getContextPath()%>/resources/js/properties.js" >
</script>

While using Spring framework in mvc you have to provide resources path as below in your dispatcher-servlet.xml.

< mvc:resources mapping="/resources/**" location="/resources/" />

And then that folder will be allowed for resources. You can call them as

< script type="text/javascript" src="../../resources/js/properties.js" >
</ script>

I have already add this line to my dispatcher. How can I check if my js is loaded? – Carlota Jul 15 '16 at 11:48
use browser to load urls manually. Either url will be wrong or file will not be at that path. – prem30488 Jul 15 '16 at 11:55
Use Tools-> Web Developer -> Web Console to see js errors. – prem30488 Jul 15 '16 at 11:56
I executed my program from eclipse. How can I do this from eclipse browser? – Carlota Jul 15 '16 at 12:08
In Eclipse Change Browser to mozilla if it is installed already, In Preferences -> General -> Web Browser, there is USe Internal Web Browswer. And you can check "FireFox". – prem30488 Jul 15 '16 at 12:10
I executed my url from chrome browser and I get the message prueba not defined – Carlota Jul 15 '16 at 12:10
It means the function is not getting or js is not fetched. Did u get message `cargado properties`? – prem30488 Jul 15 '16 at 12:21
Use `< script type="text/javascript" src="../../resources/js/properties.js" />` – prem30488 Jul 15 '16 at 12:23
I don't see message "cargado properties" – Carlota Jul 16 '16 at 17:24
