RE: Poll enrich with mail component will lose attachments

[Mi Jane 米静]

Hi Daniel,

you say you don't have an attachment, did you make sure you got at least a 
message body ???
Because the problem may come from the PollEnrich.

Jane: Yes. I got the message body but no attachment. It's working well if I use 
only mail consumer, no matter which version of camel. The problem seems to be 
come from PollEnrich + Mail with Camel 3.18.

I make a little test with my environment Camel version 3.14.3 running into 
karaf 4.3.3

Jane: It's also working well when I used Camel 3.16... it's just, I wanted to 
upgrade the Camel dependency version to fix some other issues and then found 
the problem...



Regards,
Jane

Hi Jane,
I make a little test with my environment Camel version 3.14.3 running into 
karaf 4.3.3

Here a simple rest service extract from a blueprint  deployment and it works 
very well, with and without an attachment !!!!

<rest path="/readMail"  produces="application/json" >  <description>TTT - Poll 
imap read With PollEnrich</description>  <get uri="/">
   <route id="rte.TTT.rest.readMail" >
   <pollEnrich >
     
<simple>imaps://{{SHQ_imap_server}}?username={{SHQ_imap_user}}&amp;password={{SHQ_imap_pwd}}&amp;delete=true&amp;unseen=true&amp;peek=true&amp;mapMailMessage=true&amp;closeFolder=false&amp;debugMode=true</simple>
   </pollEnrich>
   <setHeader name="zzLOG"><groovy>
   import javax.activation.DataHandler;
   import org.apache.camel.attachment.*;
   AttachmentMessage attachmentMessage = 
exchange.getMessage(AttachmentMessage.class);
   Map&lt;String, DataHandler&gt; attachments = 
attachmentMessage.getAttachments();
        if (attachments != null) {
           result="Yes attachment";
        } else {
           result="No attachment";
        }
   </groovy></setHeader>
   <log message="Attachment ? = ${header.zzLOG}"/>
   </route>
 </get>
</rest>


Regards

Daniel

Hi Claus, Hi Daniel,

Thanks for your reply!

I tried Camel 3.18.X and “&disconnect=false”. It’s still not working.

Dear community,

When I used Camel 3.11, poll enrich with mail component worked well and I could 
get the mail attachments.
When I changed to Camel 3.16 for other reasons, I could get the mail but I 
couldn’t get the attachments.

Here is an example:

……
.pollEnrich("imaps://{{mail.server}}?session=#oAuthSession&closeFolder=false&unseen=true&peek=true&folderName={{mail.sub.folder}}")
.process(new Processor() {
                @Override
                public void process(Exchange exchange) throws Exception {
                                AttachmentMessage attachmentMessage = 
exchange.getMessage(AttachmentMessage.class);
                                Map<String, DataHandler> attachments = 
attachmentMessage.getAttachments();
                                if (attachments != null) {
                                                LOGGER.info("attachments: {}", 
attachments.size());
                                } else {
                                                LOGGER.info("no attachment");
                                }
                }
})
……

With Camel 3.11 I got log “attachments: 1”, while with Camel 3.16 I got log “no 
attachment”.
Is it a known issue for Camel 3.16, or is there any extra parameter I missed? 
Thanks in advance!

Regards,
Jane
