jodd cannot sent response to view

66 Views Asked by Videanu Adrian At 25 April 2025 at 09:58

I have an app build with joy-5.0.13 where I cannot send some variable value to the template to be rendered on screen. I'm sure its something simple that I'm missing right now.
This is my action:

@MadvocAction
public class IndexAction {

    @PetiteInject
    private TemperatureService temperatureService;

    @Out
    List<TemperatureLog> temps;

    @Action    
    public void view() {        
        temps = temperatureService.getLastHoutTemperatures();       
        System.out.println(temps);      
    }

and this is the file called index.jsp

<%@ taglib prefix="j" uri="/jodd" %>
<html>
<head>
    <title>SmartHome</title>
</head>
<body>

    <j:iter items="${temps}" var="tl">
         ${tl.temperature}<br/>
    </j:iter>   

</body>
</html>

and here it is the log from the console:

80625 [DEBUG] j.m.r.AbstractTemplateViewActionResult.render:102 - target found: /index.jsp

but in the view I only get: ${tl.temperature}

it's like the result it's not reaching the view engine. I've made some debug and it seems that the actionResult is null.

Any idea what I`m doing wrong?

Thanks

P.S. I have tried the toturial and I have the same issue:

Messages

${msg.messageId} ${msg.text}
    ${resp.responseId} ${resp.text}

new message...

REST APi: message 1

that is the output that I have

This should work. Here is a working example:

@MadvocAction
public class FooAction {
    @Out
    List<Integer> temps;

    @Action
    public void view() {
        temps = new ArrayList<>();
        temps.add(30);
        temps.add(20);
        System.out.println(temps);
    }
}

This action is mapped to /foo. This is important! You need to call the action, not the .jsp in your browser. My foo.jsp code looks like yours:

Temperatures:
<j:iter items="${temps}" var="tl">
    ${tl}<br/>
</j:iter>

So, it really should work.

Maybe you can use Jodd-Joy: it is a predefined Jodd bundle. It displays the list of link nicely on the beginning, like this:

If you want, you can send me your code/example.
