First of all, I have watched the video and checked that programming rights are fine for my Admin user. the default behavior is to check for them, and the user have them, so everything is OK. Then I set 'discard success statuses' option to explicit 'No' in admin panel. Next, I have taken a sample, changed $services.mailsender.createMessage() parameters to reflect actual email before adding a page. I did try to create a velocity test email page with memory listener, but... the page did not finish loading after I clicked 'Save and View'. It was actually created, and email was prepared (log excerpt below), but email was neither sent nor displayed in Mail Sending Status (the latter is expected as we bypass DB here). Of course, no email was received and I cannot open my velocity test page due to infinite loading. I have created a thread dump for you to look at, maybe that will help: http://pastebin.com/TeBcZrUV Several email-related threads are in WAITING and TIMED_WAITING statuses. The testing page is called 'email-velocity-memory' for faster debugging.

If there's anything else I can help with, please let me know. Oh, and you will see AJP connector thread: I use 'mod_jk' to proxy Tomcat through Apache, and the Tomcat serves 2 XWikis as 2 different services. I have separated them fine (I think), but I can email you configs in case my setup is too custom and was not tested before.

Actually I have already enabled debug loglevel for mail before posting in this thread (tried to resolve this myself), I saw the lines you posted as an example in logs, but there were only preparation stage, no sending events at all. Sharing by email works with external SMTP server (have actually tested it this way first when set up SMTP, and the validation email issue was caught later when users started to register). I have shut down tomcat, removed catalina.out file to get a clean one. My steps: - start tomcat and wait till cpu load drops (that's how I tell that tomcat startup has completed without using logs); - open XWiki main page (XWiki initialization starts); - send email by sharing (old working sender plugin) - email is received; - wait a minute; - open the page with velocity I've created previously (like you told me to, using 'memory' storage); - wait for some time, check email: 1 email from share link, 2... wait, two emails from 'email-velocity-memory' page. /That is strange/: I haven't changed anything, but the email was sent this time. Twice. Now to testing email validation. - open registration page in other browser; - register a new user; - (*new*) registration successful page appears (previously that was an infinite load); - (*new*) email is received. I have an idea: the other XWiki I have installed (2 XWiki on 2 separate containers in 1 Tomcat with 2 webapp directories, I will call the first installed XWiki-0, that one does not have SMTP and sends via localhost) was not initialized (but usually is). So I will redo the same steps with starting that XWiki first (maybe there's no separation of email threads?). I stop tomcat at this point and pack the log for you (link is below). Steps this time: - start tomcat and wait till cpu load drops (that's how I tell that tomcat startup has completed without using logs); - open previously installed XWiki-0 main page (initialize it first); - share page by email - email is received; - create a velocity page (no such page was set up in XWiki-0); - 2 emails are received; - open XWiki main page (XWiki initialization starts); (there are 2 warnings in logs this time: ) - send email by sharing (old working sender plugin) - email is received; - wait a minute; - open the page with velocity - email is received (2 emails); - register a new user - registration successful, email is received. I stop my tomcat at this point and pack the log for you (link is below). Well so there is no actual interference between 2 XWiki installation when talking about email (2 warnings are present though and I don't think that's a good thing actually). Currently *everything works*. I don't know why, I was sure it wouldn't work. The only thing that can matter is that server uptime is 6 days (had a blackout last week, so the server was rebooted automatically). Previous restart was like months ago (before XWiki installation). So maybe services/containers restarts are not enough to successfully finish the installation? Reboot is needed? This is a Debian box so that's pretty strange of an idea for me, but there was nothing else. Log files: First run (single XWiki) <http://rez.hopto.org/files/catalina-single_mode.out.gz> Second run (XWiki-0 + XWiki) <http://rez.hopto.org/files/catalina-full_mode.out.gz> I will leave this set up as it is, because the issue may reappear and I don't get that was the cause of it yet. If you have any ideas, I am ready to perform more tests to get this fixed for other people who may have the same issue. -- View this message in context: http://xwiki.475771.n2.nabble.com/Email-Validation-stuck-in-prepare-success… Sent from the XWiki- Users mailing list archive at Nabble.com.
