Access Liferay Web services using JSON API - web-services

Question

Hi i created a plugin portlet. In the JSP i am accessing all countries list by using JSON API. It is working fine for Logged in users. But for the Guest users i am unable to access the web service. I am working on Liferay 6.0.6. The following is my code.
Liferay.Service.Portal.Country.getCountries(
{},
function(result) {
for(var count=0;count< result.length;count++){
alert(result[count].name);
var option = document.createElement("option");
}
}
);

Answer 1

Assuming that you are using Liferay 6.1, you can achieve it by adding a property to portal-ext.properties file
json.service.public.methods=getCountries
If you need to check the whole flow checkout
JSONServiceAction

Answer 2

I think you need to pass the serviceContext with permissions to the Service.
Can you try by setting the communityPermissions and guestPermissions as VIEW ?
Liferay.Service.Portal.Country.getCountries(
{
serviceContext: jQuery.toJSON(
{
communityPermissions: communityPermission,
guestPermissions: guestPermission,
scopeGroupId: themeDisplay.getScopeGroupId()
}
)
},
function(result) {
for(var count=0;count< result.length;count++){
alert(result[count].name);
var option = document.createElement("option");
}
}
);

I found a work around for the above problem. I am unable to access JSON API because Liferay is using A.io.request for AJAX Calls which is available for Logged in Users only. So I have prepared the following code.
jQuery.ajax({
type: "POST",
url: '<%=themeDisplay.getURLPortal() %>'+'/tunnel-web/json?serviceClassName=com.liferay.portal.service.CountryServiceUtil&serviceMethodName=getCountries',
dataType: 'json',
success: function(countriesList) {
alert(countriesList);
alert(countriesList[0].countryId);
}
}
});
