How to send email notifications template in cq5

The process involves three steps.

We can send email template by using the workflow also. But this is the process without using the workflow.
For this,

1) We need to interact with the form, for the values which are required to pass to the mail template.
2)Sending the values to the servlet by using Ajax call
3)Interact with the servlet and inject values into mail template using the appropriate methods.


Here is the code for send an email template.

package com.test.mailtemp;

    private static final Logger log = LoggerFactory.getLogger(mailtemp.class);    
    ArrayList<InternetAddress> emailRecipients = new ArrayList<InternetAddress>();  
    @Reference
    private MessageGatewayService messageGatewayService;   
    @Reference
    private MessageGateway<HtmlEmail> messageGateway;   
    @Reference
    private ResourceResolverFactory serviceRef;
    private ResourceResolver resResolve = null;   
    String param1,param2=null;   
    private Session session;  
   
    @Reference
    public SlingRepository repository;
   
    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException,IOException {

     mailCall(param1, param2);         
    }   
    public void mailCall(String param1, String param2){      
        try{
        session = repository.loginAdministrative(null);
        Resource templateRsrc;
        HtmlEmail email = new HtmlEmail();
        String msg = "Hello, Our testing has completed here you got the mail !!!";

        Map<String, String> mailTokens = new HashMap<String, String>();
        mailTokens.put("subject", "Testing the mail template");
        mailTokens.put("param1", param1);
        mailTokens.put("param2", param2);
        mailTokens.put("thanks", "Thanks");
        mailTokens.put("author", "SONY C.");       
        mailTokens.put("message",msg);  
         
            templateRsrc = serviceRef.getAdministrativeResourceResolver(null).getResource("/etc/workflow/email");
            templateRsrc = templateRsrc.getChild("templatestructure.html");
            final MailTemplate mailTemplate = MailTemplate.create(templateRsrc.getPath(), session);
            String recipientName = "sonycharan004@gmail.com";
            String sendTo = "sonycharan004@gmail.com";
            String recName = "Sony C";
        
            mailTokens.put("contactName", "Dear "+recipientName);

            emailRecipients.add(new InternetAddress(sendTo) );
            email = mailTemplate.getEmail(StrLookup.mapLookup(mailTokens),HtmlEmail.class);
            email.setTo( emailRecipients );
        
            messageGateway = this.messageGatewayService.getGateway(HtmlEmail.class);
            messageGateway.send(email);
        
        }
        catch (AddressException e) {           
            e.printStackTrace();
        }catch (MessagingException e) {          
            e.printStackTrace();        
        } catch (EmailException e) {         
            e.printStackTrace();
        }
        catch(Exception e)  {
            e.printStackTrace();         
        }finally{
        session.logout();
        }
    }
   
}




II)As mentioned above we need to create a mai template in the path "/etc/workflow/email"  and under this create a file named "templatestructure.html"


Template Structure would be----

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
 <title>Tempate Demo</title>
</head>
<body topmargin="0" bottommargin="0">

Dear  ${contactName},

Sub: ${subject},
${message}.
And your text will be  ${param1}, ${param2}.

How to get node properties in jsp in cq5

Here is the procedure to get node properties in a jsp in cq5


<%@page session="false"%>
<%@ page import="java.util.Locale,
java.util.ResourceBundle,
javax.jcr.NodeIterator,
javax.jcr.Session,
javax.jcr.Node, javax.jcr.Value, javax.jcr.NodeIterator,
com.day.cq.commons.jcr.*" %>
<%@include file="/libs/foundation/global.jsp" %>

<%
javax.jcr.Session ses = resourceResolver.adaptTo(Session.class);
        //If you want to save anything to the node this session object (ses)is required.
String nodePath="/content/****";
Resource resources = slingRequest.getResourceResolver().getResource(nodePath);
         //Creating Node object using adaptTo mehtod.
Node rootNode = resources.adaptTo(Node.class);

*****Here is the node "rootnode", and now we can explore subnodes by using the root node and their propeties.

Comments are most welcome!!!
Thanks,
