unable to access JSONObject in sightly html file

Hi,

I am trying to access JSONObject  in sightly html,but the data is not displayed.

Below is the sightly java file,where "result" variable is holding JSON string.

public class TestSightly extends WCMUse {

   public String result;
   public JSONObject jsonObject;   
    
    @Override
    public void activate() throws Exception {
        TestLocation testLocation = new TestLocation();
        result = testLocation.testMessage();
        jsonObject = new JSONObject(result);
        
    }

     public String getResult(){
        return result;
    }
    
    public JSONObject getJsonObject(){
        return jsonObject; 
    }
       
}

HTML File:

<div data-sly-include="/libs/wcm/core/components/init/init.jsp"></div>

<div data-sly-use.model="${'com.test.core.models.TestSightly'}">
 <div>${model.result}</div>
 <div>${model.jsonObject}</div>

</div>

 

With the above "model.result" is displaying the string data(json formatted data),but "model.jsonObject" is displaying nothing.

 

Thanks & Regards

    Issue fixed.Found alternate way.

    Instead of using org.apache.sling.commons.json.JSONObject API, I changed to GSON api and converted json to javabean object and then accessing in sightly file.

    But using JSONObject in sightly is still not possible.

    I got the same issue, I spent one day to understand why I'm unable to get the value of a JsonObject in sightly (only key) if the JsonObject come a java code with org.apache.sling.commons.json.JSONObject;

    At the end I end up with another solution than the use of Gson api.

    I used a JS conversion between java and sightly. I gave my Java JsonObject to a Javascript method JSON.parse()

    something like:

    html

    <sly data-sly-use.greatdeals="GreatDeals" />

        <sly data-sly-use.greatdealsJS="${'greatdeals.js' @ jsonString=greatdeals.jsonGreatDeals}" />

    <sly data-sly-list.deal="${greatdealsJS}">

        <div>${deal} : ${greatdealsJS[deal]}</div>

    </sly>

    greatdeal.js:

    use(function () {

        return JSON.parse(this.jsonString);

    });

    GreatDeals

    public JSONObject getJsonGreatDeals() {

            JSONObject jsonObject = null;

            try {

                jsonObject = new JSONObject();

                jsonObject.put("deal1", "test1");

                jsonObject.put("deal2", "test2");

                jsonObject.put("deal3", "test3");

            } catch (Exception e) {

                LOGGER.error("Could not create JSON", e);

            }

            return jsonObject;

        }

    it's not beautiful but it works.

    that is the nice thing about AEM - you are not bound to a specific API. Its essentially a JAVA platform, so you can use a specific Java API that will solve your business requirements.

    A rule is the Java API must be in a OSGi bundle and in an active state so other bundles can use that API.

    We have an article that shows use of the GSON API in a Java backend:

    I agree with you and it's one of many reason I do JAVA and not .Net, because you can use and mix different API.

    I just start with sightly instead of doing everything with a JSP, and was a litlle upset to not understand why an API from Google works better than an API from Apache in AEM
