Unable to retrieve Java variable in JavaScript

Seeking guidance on how to retrieve Json data stored in a Java variable using JavaScript. Instead of accessing the data, the html source is displayed.

Java:

 Gson gson = new Gson();
 String json = gson.toJson(obj);
 request.setAttribute("gsonData", gson);

JavaScript:

var dataset = ${gsonData};

The content in the html page source:

var dataset = {serializeNulls:falsefactories:[Factory[type=com.google.gson.JsonElement,
adapter=com.google.gson.internal.bind.TypeAdapters$25@719474],
com.google.gson.internal.bind.ObjectTypeAdapter$1@31d22,
... // (data continues)
instanceCreators:{}};

In what way can I appropriately access this data?

javascriptjavajsonjsp

Answer №1

Your input was:

request.setAttribute("gsonData", gson);

However, consider changing it to:

request.setAttribute("jsonData", json);

So, should we replace the content of obj instead of using the GSon object?

Answer №2

Give it a shot using this code snippet:

let data = JSON.parse(jsonData);
data['skipNulls:truebuilders'].Builder;
