How to convert arraylist of custom object in to json in javascript

Question

I have a (java.util.List) List returned to the jag. That should be printed as a json .

   var storeForum = Packages.org.wso2.carbon.forum.registry.RegistryForumManager;

   var forum = new storeForum();

   var start = request.getParameter('start');
   var count = request.getParameter('count');

   var array =forum.fetchForumTopics(start,count, tenantDomainsArr, -1234, user.username);

forum.fetchForumTopics method returns

    List<customOjbect>

How to print it as a json. Didn't find anything useful on net.

You'll have to decide what you want, JSON is a dataformat for strings, an object is a native javascript structure of data, they are in no way the same thing. — adeneo

i'm not quite sure what a jag is - but you can use JSON.stringify() to convert an array of pairs or values into a JSON object

JSON.stringify(array)

This doesn't work. It only gives "{}" as the output even though returned list is not empty.

Since this is a java object, can you try this conversion using a java module that can convert the respective Object to JSON?.. You may have to import that module to the .jag (jaggery) file.

That'll work.But I wonder if there's a way to do this conversion with out having to import any java module.
