Docusign:- The recipient you have identified is not a valid recipient of the specified envelope

Question

Am new to docusign and trying to use the embeding feature. Here's the steps I followed:

1. Created a template with a sample document uploaded. For the Receipent and Routing section, i created one role but didnt give the email and name. Since i need to send the same template to different people
2. Used the JAVA code exactly as in http://iodocs.docusign.com/APIWalkthrough/embeddedSigning
3. Provided the required values such as integratorKey,username,password,recipientName,recipientEmail,templateId,roleName
4. Am getting the below error and not sure how to resolve.

Step 3: Generating URL token for embedded signing... API call failed, status returned was: 400 Error description:

<?xml version="1.0" encoding="UTF-8"?>
<errorDetails xmlns="http://www.docusign.com/restapi" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
  <errorCode>UNKNOWN_ENVELOPE_RECIPIENT</errorCode>
  <message>The recipient you have identified is not a valid recipient of the specified envelope.</message>
</errorDetails>

Answer 1

Fixed it! There was an issue in the code given in that site. In step 2 it was given:

body = "<envelopeDefinition xmlns=\"http://www.docusign.com/restapi\">" +
"<accountId>" + accountId + "</accountId>" +
"<status>sent</status>" +
"<emailSubject>DocuSign API Call - Signature request from template</emailSubject>" +
"<templateId>" + templateId + "</templateId>" +
"<templateRoles>" +
"<templateRole>" +
"<email>" + username + "</email>" + 
"<name>" + recipientName + "</name>" +
"<roleName>" + roleName + "</roleName>" +
"<clientUserId>1001</clientUserId>" +   // required for embedded sending (value is user-defined)
"</templateRole>" +
"</templateRoles>" +
"</envelopeDefinition>";

"<email>" + username + "</email>" is wrong. "<email>" + recipientEmail + "</email>" should be used instead.
