Unable to invoke bundle class using sightly

Avatar

Level 4

Hi 

I am unable to invoke bundle class from sightly. I can able to access the same class using scriptlet in jsp.

my code looks similar to this :

 

<div data-sly-use.mycomp="${ 'com.myproject.MyComponent'}"> ${mycomp.calculatedValue} </div>

Above code is giving error like : use is not able to find 

'com.myproject.MyComponent'

when I remove single codes, I am not getting error. but MyComponent class is not invoking. I have extended WCMUse class in MyComponent.

Pls help me to resolve this issue.

Regards,

Krishh

Hi,

Make sure you are exporting your packages

No need to use curly braces

Create a project with archetype 10 and take a look at hello world component..

Here is the example which shows this use case:http://adobeaemclub.com/access-osgi-ser­vice-from-the-wcmuse-class-in-sightly/

Hi,

Thanks for the reply 🙂

Still I am unable to invoke the java class.

PFA code snippets :

<%@page session="false"%><%@ page import="com.day.cq.wcm.foundation.Placeholder" %>
<%
%><%@include file="/libs/foundation/global.jsp"%><%
%>

 

<div data-sly-use.districtinfo="com.aem.emitra.core.sightly.districtinfo">
    ${districtinfo.emitraDistricJson}
</div>

 

 

package com.aem.emitra.core.sightly;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.adobe.cq.sightly.WCMUse;

public class districtinfo extends WCMUse {

    //private EmitraDistrictServiceImpl  emitraDistrictServiceImpl;
    private String emitraDistricJson;
    private Logger logger = LoggerFactory.getLogger(this.getClass());

    @Override
    public void activate() {

        logger.info("inside districtinfo");
        //emitraDistricJson=emitraDistrictServiceImpl.getDistrictsJSON();
        emitraDistricJson="KRISHH";
    }

    public String getEmitraDistricJson() {
        return emitraDistricJson;
    }

}

Hey,

What is the extension of file in which you have written 

<%@page session="false"%><%@ page import="com.day.cq.wcm.foundation.Placeholder" %>
<%
%><%@include file="/libs/foundation/global.jsp"%><%
%>

 

<div data-sly-use.districtinfo="com.aem.emitra.core.sightly.districtinfo">
    ${districtinfo.emitraDistricJson}
</div>

You cannot have java code inside sightly file

Yeah. I tried with html also like

<div data-sly-use.districtinfo="com.aem.emitra.core.sightly.districtinfo">
    ${districtinfo.emitraDistricJson}
</div>

 

its not working. I was thinking about hw sightly will get that path of districtinfo.java . So I have changed again to jsp extension with import statements.

even with the above code I am not able to invoke districtinfo.java.

Go to localhost:4502/system/console/services and see whether your service is available or not.

Use

<div data-sly-use.districtinfo="com.aem.emitra.core.sightly.districtinfo">
    ${districtinfo.emitraDistricJson}
</div>

and share the error from error.log

I have not created any service. My bundle is in http://localhost:4502/system/console/bundles. Do I need to create service? Here I am just displaying hardcoded value. Can you share  your gmail id?

Hey edubey,

I have tried by changing class name as EmitraDistricts. Now it started working. Is there any naming conventions? I have followed component name initially.

Anyways thanks mate. Thanks alot.

Though I have included the import of package also not working

<%@page session="false"%>

I do agree that you have included packages but sightly files have .html extension in which you cannot write java code

So please remove 

<%
%><%@include file="/libs/foundation/global.jsp"%><%
%>
<%@page session="false"%>
<%@ page import="com.day.cq.wcm.foundation.Placeholder,
    com.aem.emitra.core.sightly.districtinfo"
%>
