smtp server setup
by jgehbauer＠gmail.com 25 Mar '08

25 Mar '08

Hello! I installed a new instance of xwiki on my local machine. I tried to set up the email notification but it didn't really work. In the XWiki Preferences I set the outgoing smtp server to several smtp servers such as smtp.google.com, smtp.comcast.net, etc. Howver, there seem to be some authentication issues and I get the following error message: *** Error number 4001 in 4: Error while parsing velocity page Demo.SendMailTestPage Wrapped Exception: Invocation of method 'sendMessage' in class com.xpn.xwiki.XWiki threw exception class com.xpn.xwiki.XWikiException : Error number 10006 in 10: Could not send mail to server smtp.comcast.net port 25 error code 530 (530 Authentication required ) OR Error number 4001 in 4: Error while parsing velocity page Demo.SendMailTestPage Wrapped Exception: Invocation of method 'sendMessage' in class com.xpn.xwiki.XWiki threw exception class com.xpn.xwiki.XWikiException : Error number 10006 in 10: Could not send mail to server smtp.gmail.com port 25 error code 530 (530 5.7.0 Must issue a STARTTLS command first h14sm757315wxd ) *** I also tried to use my own smtp server (hmailserver) but then I had some relay problems and the following error message: *** Error number 4001 in 4: Error while parsing velocity page Demo.SendMailTestPage Wrapped Exception: Invocation of method 'sendMessage' in class com.xpn.xwiki.XWiki threw exception class com.xpn.xwiki.XWikiException : Error number 10006 in 10: Could not send mail to server mail.hmailserver.com port 25 error code 550 (550-207-105-15-139.ded.pacbell.net (XWiki version 0.9.840) 207.105.15.139? is 550-currently not permitted to relay through this server. Perhaps you have not 550-logged into the pop/imap server in the last 30 minutes or do not have SMTP 550 Authentication turned on in your email client. ) *** I have right now no idea how to resolve these issues. I would appreciate any help in setting up the smtp server for the email notification. Cheers, Jens

xwiki.com stats deactivated
by Ludovic Dubost 09 Dec '07

09 Dec '07

Hi, We got a new load of spam related hammering on xwiki.com. It is more and more horrible and creates more and more unuseful load on xwiki.com. Spam robots have included creation of XWiki accounts and use of these accounts to publish spam data in the wiki pages. I've had to deactivate statistics since each spam-related request that cannot be catched by mod_security creates load on the database for these statistics. The only way to get statistics back will be to use Javascripts which triggers a statistics storage request in the database (which would be ignored by spam robots and search engines), or to wait until we can read Google Analytics or another external statistics engine and redisplay it on xwiki.com. In the future we will propose a tutorial to activate Google Analytics on your wikis. If you know how to do it you should include this on your wiki pages to get statistics for your wiki. I'm getting more and more worried about these spam robots and would welcome any help and ideas on how to handle this to make xwiki.com a viable platform for hosted public wikis.

XWiki.com upgraded to 0.9.1252
by Ludovic Dubost 11 Sep '06

11 Sep '06

Hi, We have just upgrade xwiki.com to version 0.9.1252 (available on ObjectWeb). If you are users of XWiki.com and you see anything special that could be caused by the upgrade, please contact us at support-en(a)xwiki.com Version 1252 has many changes under the hood and some in the user interface. The main changes from a user/admin perspective are: - the new WYSIWYG editor which is compatible with Wiki syntax. - the Rights page which now contains select fields The WYSIWYG Editor is still in beta state. It is not activated by default but can be called using the "switch to WYSIWYG Editor" link in the edit page. You can activate the wysiwyg editor by default in the XWiki Preferences in the "editor" section. Under the hood, maybe other changes are now available including better performance by generating less queries to the database. New plugins and APIs are also available for programmers. We will talk more about these a little later when we officially release this version. We are now working to integrate: - AntiSpam measures (using JCaptcha) - as a new registration and invitation system which should be more easy to use and flexible. - editing by sections We will of course all fix any bugs in the features of 1252 and work is also in progress for a new layout and skin.

Broken PDF export
by Ryszard Lach 05 Sep '06

05 Sep '06

Hi. We are using xwiki for almost two years (as internal knowledge base) and although we still have some problems - thank you very much for all you work, I hope we will be able to solve some paining issues ;-), I'm pretty determined to dig until success, I count on your help and promise to give sufficient feedback. Our main problems are: * broken PDF export (generated null-byte files) * broken search on non-latin1 characters (that I'll describe in separate thread) Hera are the details My platform is: tomcat 5.5.17 running in locale pl_PL.UTF-8 JDK 1.5.0 mysql 5.0 with default charset UTF-8 (and DB in UTF-8 too). xwiki.war 9.840, but the same bahaviour is on latest SVN trunk. I suppose that problem with PDF export has something to do with UTF-8. I'm pretty sure I have UTF-8 configured properly (xwiki.encoding in xwiki.cfg and filter in web.xml), non-latin1 characters are being properly written to and read from database, are also properly rendered in xwiki pages. When I click PDF export link (even viewing document containing only ASCII characters) I receive an empty file and some entries in catalina.out: ######## <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title> Wiki - Sandbox - TestTopic1 </title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="revisit-after" content="7 days" /> <meta name="description" content="Intranet Wiki" /> <meta name="keywords" content="wiki" /> <meta name="distribution" content="GLOBAL" /> <meta name="rating" content="General" /> <meta name="copyright" content="you need to choose your copyright" /> <meta name="author" content="" /> <meta http-equiv="reply-to" content="" /> <meta name="language" content="pl" /> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> [...] line 5 column 1 - Warning: <html> has XML attribute "xml:lang" [Fatal Error] :78:27: Invalid byte 1 of 1-byte UTF-8 sequence. 19:53:36,729 WARN TP-Processor4 https://xwiki.biuro.contium.pl:5443/xwiki/bin/pdf/Sandbox/TestTopic1 XWikiAction:execute:185 - Uncaught exception: Error number 12003 in 12: XSL Transformation Failed Wrapped Exception: Invalid byte 1 of 1-byte UTF-8 sequence. com.xpn.xwiki.XWikiException: Error number 12003 in 12: XSL Transformation Failed Wrapped Exception: Invalid byte 1 of 1-byte UTF-8 sequence. at com.xpn.xwiki.pdf.impl.PdfExportImpl.applyXsl(PdfExportImpl.java:176) at com.xpn.xwiki.pdf.impl.PdfExportImpl.convertXHtmlToXMLFO(PdfExportImpl.java:154) at com.xpn.xwiki.pdf.impl.PdfExportImpl.exportXHtml(PdfExportImpl.java:86) at com.xpn.xwiki.pdf.impl.PdfExportImpl.exportHtml(PdfExportImpl.java:115) at com.xpn.xwiki.pdf.impl.PdfExportImpl.export(PdfExportImpl.java:129) at com.xpn.xwiki.pdf.impl.PdfExportImpl.exportToPDF(PdfExportImpl.java:119) at com.xpn.xwiki.web.PDFAction.render(PDFAction.java:45) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:146) [...] ######## Do you any have any idea what can be the cause of this exception? I suppose that ' <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">' has nothing to do, although I don't know why lang, content-type and charset are derived both from templates/httpheader.vm and xwiki->preferences. I hope I will be able to run it under eclipse soon, maybe I find the problem.... Best regards, Richard. -- "First they ignore you. Then they laugh at you. Then they fight you.

Converting from XWiki to TWiki
by Paul Dlug 31 Aug '06

31 Aug '06

We just completed a conversion from XWiki to TWiki because of the numerous limitations of XWiki (really awful to understand permissions system, slow pace of development, lack of plugins, horrid look and feel, etc.). We initially tried to convert the syntax to TWiki using perl with Parse::RecDescent. Since the grammar is rather unstructured and regex/exception based this isn't an easy thing to do. We were successfully in hacking up a version of XWiki/Radeox that outputs the XWIki syntax as TWiki syntax. Since this uses the native structures inside the original java code the conversion is much cleaner. If anyone else is migrating from XWiki to TWiki let me know if you'd like the code to batch convert the whole wiki at once. I'm happy to save others the pain of doing this themselves. As an aside, I am dismayed at the slow progress of XWiki in the time we have been using it (over a year and a half). I was also quite appalled when I started digging into the code to this, it's messy, undocumented, and rife with duplicate logic.

still problems with parsing of history
by David Delbecq 31 Aug '06

31 Aug '06

Hello, I did as you suggested and issued the following mysql command: update `xwikidoc` set XWD_ARCHIVE=NULL WHERE XWD_FULLNAME="Direction.QuifaitquoiIrm" however, i still get the nearly same error. This time it doesn't complain it can't parse 'oma.be', it complains it can't parse '' (yes, the empty string, at line 0 column 0) How do i cleanly remove the archive?

Using XWiki in other databases than MySQL
by Ludovic Dubost 31 Aug '06

31 Aug '06

Hi, In order to possibly improve our database support in the future, I would be interested to discuss with any users that have ported XWiki to other databases than MySQL. We are especially interested by databases used by corporations like Oracle, Sybase, SQL Server. Would any of you that have ported/tried to port XWiki to another database tell us what has worked/not worked and what they have done. That would be great help. Since we now have the default database of XWiki as XML, we have the possibility to write a script to load this in any database. We just need to make sure that the core behavior of the storage engine is compatible with the target database.

Adding objects dynamically
by Esbach, Brandon 31 Aug '06

31 Aug '06

Hi All, Managed to work out most issues from a previous email, however I'm still stuck on two elements of the problem: 1) How to add objects dynmically from another object after creation (for eg, getting a document object and looping through the objects to add it's objects to the new document - can loop fine, but adding more does not seem to be working right) 2) Sending an email to a user when a particular update is done to the document (user clicks on approve/decline for example). This assumes the email address is correctly entered. Any pointers/suggestions would be welcome!
