Retrieving File Attachments from adobe adaptive form

@vish.dhaliwal @arunpatidar  Any pointers here?

You want to access attachments after the form is submitted?

are you using AEM workflow?

When you add attachments to AF they are stored in tmp location. Every time an attachment is added to AF you can use the event handler to get the location of the file and write that location to the hidden field in your AF. When you form is submitted your servlet can extract the attachments from that location and do the needful

I am attaching a simple form with a custom client lib. Preview the form and add attachments.You should see the text field populated with the path to the attachments

import the two packages using package manager

then preview the TestAttachments form

add a couple of attachments

you should see the path of the attachments written to the text box

You can decompile using any java decompiler online 

there is interface and servlet that makes up the code

package com.aemforms.handleafsubmission.core.servlets;

import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.Map;

import javax.servlet.Servlet;
import javax.servlet.ServletException;

import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.request.RequestParameter;
import org.apache.sling.api.request.RequestParameterMap;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
import org.osgi.service.component.annotations.Component;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.adobe.aemfd.docmanager.Document;
@8220494(service = {
Servlet.class
}, property = {
"sling.servlet.methods=get",
"sling.servlet.methods=post",
"sling.servlet.paths=/bin/getsubmitteddata"
})

public class GetSubmittedData extends SlingAllMethodsServlet {

Logger logger = LoggerFactory.getLogger(GetSubmittedData.class);

private static final long serialVersionUID = -8884406699033680092 L;
protected void doPost(final SlingHttpServletRequest request, final SlingHttpServletResponse response) throws ServletException {
// get the submitted form data
String submittedData = request.getParameter("jcr:data");
logger.debug(submittedData);
RequestParameterMap requestParameterMap = request.getRequestParameterMap();
for (Map.Entry < String, RequestParameter[] > pairs: requestParameterMap.entrySet()) {
final org.apache.sling.api.request.RequestParameter[] pArr = pairs.getValue();
final org.apache.sling.api.request.RequestParameter param = pArr[0];
if (!param.isFormField()) {
try {
logger.debug("Got attachment!!!!" + param.getFileName());
InputStream is = param.getInputStream();
Document attachment = new Document(is);
attachment.copyToFile(new File(param.getFileName().split("/")[1]));
attachment.close();
} catch (IOException e) {
logger.debug(e.getMessage());
}
}

}

}
