Unable to submit AEM adaptive form to internal servle...

[priyadarshi_cts]

Hi,

I am trying to submit an adaptive form with three fields to an internal servlet /bin/sling/adaptiveformssubmit

I followed the steps here and created the below configs

      

I added the below configs in the submit section.

I always get the default message "Thank you for submitting the form." and the form data does not reach the back end servlet.

This is my post.POST.jsp

<%@include file="/libs/fd/af/components/guidesglobal.jsp" %>
<%@page import="org.apache.sling.api.resource.ResourceUtil,
com.adobe.cq.social.commons.CollabUtil,
org.apache.sling.jcr.api.SlingRepository,
org.apache.sling.api.resource.ValueMap,
java.util.concurrent.atomic.AtomicInteger,
org.slf4j.Logger,
org.slf4j.LoggerFactory,
org.apache.sling.jcr.base.util.AccessControlUtil,
org.apache.jackrabbit.api.security.user.UserManager,
com.adobe.aemds.guide.service.GuideStoreContentSubmission,

javax.jcr.security.AccessControlList,
javax.jcr.security.AccessControlPolicyIterator,
javax.jcr.security.AccessControlManager,
javax.jcr.security.AccessControlPolicy,
com.day.cq.commons.jcr.JcrUtil,
com.adobe.aemds.guide.servlet.GuideSubmitServlet,
com.adobe.aemds.guide.utils.GuideConstants,
com.day.cq.wcm.foundation.forms.FormsHelper" %>
<%@ page import="org.apache.commons.lang3.StringUtils" %>

<% final AtomicInteger uniqueIdCounter = new AtomicInteger();

%>
<%@taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0" %>
<%
%>
<%@taglib prefix="cq" uri="http://www.day.com/taglibs/cq/1.0" %>
<cq:defineObjects/><sling:defineObjects/>
<%
log.info("Inside Contact Us!");
FormsHelper.runAction("/bin/sling/adaptiveformssubmit", "post", resource,
slingRequest, slingResponse);
//GuideSubmitServlet.setForwardPath(slingRequest, "/bin/sling/adaptiveformssubmit", null, null);

%>

I have also tried to directly link the servlet as a REST Endpoint like below 

This throws a 500 error on the page.

Please let me know if I am missing any configurations for the submit action to work on a servlet

Can you please refer to the link below for the same:

https://docs.adobe.com/content/help/en/experience-manager-learn/forms/handling-af-form-submissions/s....

Hope this helps.

Hi, I tried this above approach. However, I can't seem to get the values in the back end through request.getParameter(). I have named the textbox field "username". But when I try to get the value with request.getParameter("username"), I always get NULL as the param is not present.

[GirishBedekar]

Can you please enumerate through all the request parameters and write the parameter names to the log file

use request.getParameterNames and the. Loop through the enumeration 

I think you will find a request parameter called jcr:data which will have the data submitted 

[priyadarshi_cts]

I tried to get the names, it comes as empty. I enabled the logs on AEM, I see the following entry. Not sure if we need to specifically mention the encoding type anywhere in the forms.

com.adobe.aemds.guide.service.impl.RESTSubmitActionService RESTSubmitActionService: Content type is either is null or does not contain application/x-www-form-urlencoded

[GirishBedekar]

Can you please check if the servlet resolver is resolving correctly to your servlet path

also can you please paste your servlet code?

[priyadarshi_cts]

okay, the problem was my tomcat server was not configured to accept the multiform data. Now I am getting the values back into my servlet. However, it is coming as "jcr:data" and "dataXml" with identical content

"<afData><afUnboundData><data><username>testing user</username><password>testing password</password></data></afUnboundData><afBoundData><data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/"/></afBoundData><afSubmissionInfo><computedMetaInfo/><signer...>"

Is there any OOTB configuration which can transform to a normal HTTP POST request that can be retrieved by request.getParameter("username") ? Or this has to be a custom submit action to send the values to be servlet in that format?

[GirishBedekar · Accepted solution]

you will have to parse the submitted data as xml in your servlet which handles the form submission and then fetch the appropriate elements value using xpath or org.w3c.dom.Document methods
