java - JSON response Issue for Jira Rest Client -

when use following method :

public string getprojectlist() {     projnames = new arraylist<>();     projnames.add("project1");     projnames.add("project2");     projnames.add("project3");     return new gson().tojson(projnames); 

in following code :

 $(document).ready(function() {         $.getjson('dbdropdown', function(resp) { // on sucess             var $select = $('#someselect');             $select.find('option').remove();             $select.prepend("<option value='select project'></option>").val('');             $.each(resp, function(key, value) { // iterate on json object.                 $('<option>').val(key).text(value).appendto($select); // create html <option> element, set value iterated key , text content iterated item , append <select>.             });         }).fail(function() { // on failure             alert("request failed.");         });     }); 

and jsp call :

response.getwriter().write(musicdatabase                 .getinstance()                 .getprojectlist() 

i able dropdown menu. when use method in place of getprojectlist dont response when check chrome developer tools , debug.

public string names() throws urisyntaxexception{     names = new arraylist<>();     uri uri = new uri("https://jira.xxxxx.com");     jirarestclientfactory jrcf = new asynchronousjirarestclientfactory();     jirarestclient jrc = jrcf.createwithbasichttpauthentication(uri, "xxx", "xxxx");      iterable<basicproject> allproject = jrc.getprojectclient().getallprojects().claim();     for(basicproject project : allproject){         names.add(project.getname());     }      return new gson().tojson(names); }
