Call OSGI service from HTML or Javascript

[Former Community Member]

Hi,

I have created a HTML page with a form, and an OSGI service to save the data and send email. I want to know whether it is possible to call the OSGI service using Javascript or HTML without the component?

The HTML page that I have created does not using the CQ template or component, it is just a pure HTML file with some Javascripts.

<form id="aForm" action="">

<input type="text" class="textbox" name="contactNumber" />

....

</form>

Thanks.

instead of a service, use a servlet and call the same using javascript or html. Refer [1] for the example

Hi 

Adding one more helpx reference for your help:-

Link:- https://helpx.adobe.com/experience-manager/using/first-osgi.html

// Once OSGI is deployed, 

We can call OSGI functions from JSP like:-

<%@include file="/libs/foundation/global.jsp"%>

<h1><%= properties.get("title", currentPage.getTitle()) %></h1>

<%

com.adobe.cq.KeyService keyService = sling.getService(com.adobe.cq.KeyService.class);

keyService.setKey(10) ;

String ff = keyService.getKey();

%>

<h2>This page invokes the AEM KeyService</h2>

<h3>The value of the key is: <%=ff%></h3>

Option 2:- 

As mentioned by Lokesh, invoking it by Ajex request.

I hope this would be useful for you.

Hi,

I have tried to use the servlet, but I got this error by the empty CSRF token. May I know how to include this token in the html?

In the example article I have found https://helpx.adobe.com/experience-manager/using/custom-sling-servlets6_1.html, it is mentioned to use the <cq:includeClientLib categories="cq.jquery" /> 

In my case, I did not use the template JSP. Is there a way to include this CSRF token in HTML?
