AEM 6.3: Error 500 while doing a POST request
I have created a POST servlet like below:
package com.aem.sites.servlets;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
import org.osgi.service.component.annotations.Modified;
import org.osgi.service.metatype.annotations.Designate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.aem.sites.interfaces.SubscriptionConfiguration;
import java.io.IOException;
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
@Component(
immediate = true,
service = Servlet.class,
configurationPid = "com.aem.sites.servlets.SubscriptionSevlet",
property = {
"sling.servlet.methods=POST",
"sling.servlet.selectors=newsletters",
"sling.servlet.resourceTypes=aemsite-project/components/structure/page",
"sling.servlet.extensions=html"
}
)
@Designate(ocd=SubscriptionConfiguration.class)
public class SubscriptionSevlet extends SlingAllMethodsServlet{
/**
*
*/
private static final long serialVersionUID = 1L;
/** The Constant logger. */
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Override
protected void doPost(final SlingHttpServletRequest req, final SlingHttpServletResponse res) throws IOException, ServletException {
logger.info("======================inside do post for subscription servlet========================================");
}
/**
* Activate.
*
* @param config the config
*/
@Activate
@Modified
protected void Activate(SubscriptionConfiguration config) {
logger.info("********************************inside subscription servlet*****************************************"+config.sampleProperty());
}
}
and this is the configuration Interface
package com.aem.sites.interfaces;
import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.AttributeType;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;
@ObjectClassDefinition(name="Subscription Configuration", description="Configuration interface for Subscription Servlet")
public @interface SubscriptionConfiguration {
@AttributeDefinition(
name = "Sample property",
description = "Sample property",
type = AttributeType.STRING
)
public String sampleProperty() default "sample test";
}
I am calling the servlet using resourceType and selector.The servlet is being called through a form:
<div id="login-box" style="padding-top:5%;padding-left:3%">
<div class="left">
<h1>Sign up</h1>
<form method="POST" name="subscriptionForm" id="subscriptionForm" action="/content/aemsite/en/subscribe.newsletters.html">
<input type="text" name="name" placeholder="Name" style="width:30%" />
<input type="text" name="email" placeholder="E-mail" style="width:30%"/>
<input type="submit" name="signup_submit" value="Sign me up" />
</form>
</div>
</div>
this is the JS being included through clientlibs
$(function() {
var formURL = $("#subscriptionForm").attr('action');
var method = $("#subscriptionForm").attr('method');
$("#subscriptionForm").submit(function(event) {
event.preventDefault();
$.ajax({
url:formURL,
data: $("#subscriptionForm").serialize(),
type: method,
success: function( data, textStatus, jQxhr ){
$('#response pre').html( data );
},
error: function( jqXhr, textStatus, errorThrown ){
console.log( errorThrown );
}
});
});
});
The clientlibs that are being included as dependencies are given in the screenshot clientlibs.png below
The above is the error I am seeing on the chrome debuuger is "Failed to load resource: the server responded with a status of 500 (Server Error)"
The screenshot is given below:
I have read that from AEM 6 onwards more security measures are being adopted for POST request and hence a CSRF token is being used but it is mostly handled if AEM's version of jQuery is used.
I have also used jcrresolver to check if the path is being resolved and here is the screenshot attached of that:
The servlet's status is also active.
I am not sure what is it that I am doing incorrectly. Any help is appreciated.
Thanks

I just tested Mail List Component solution. It works nicely --
Data was posted to Servlet and put into the database
