smtp server setup

by jgehbauer＠gmail.com

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

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 error 3021

by Frederic Aymard

Hi, I've been using xwiki for a month now without problems. I use it as an internal tool with less than 5 users. Yesterday I have started to have some problems when saving pages. When I write a add text to an existing page or I write a new page I often (not always) have the following error: Error number 3201 in 3: Exception while saving document Projects.xwikiPb Wrapped Exception: Could not execute JDBC batch update com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document Projects.xwikiPb Wrapped Exception: Could not execute JDBC batch

When I edit it, I have a similar exception but for the XWD_ARCHIVE column When I delete the page I have another exception saying that the page does not exist even thought it is still displayed When I restart Tomcat, the page is really deleted. I am using: - Tomcat 5.0 (same problems with Tomcat 5.5) - MySql 5.0 (I check tables for corruption with mysql administrator and everything seems fine) I tried the following to solve my problem without success: - I already configured xwiki to support large attachments. - I modified the hibernate.cgf file with the useServerPrepStmts=false option - I tried with mysql 5.0 driver - I checked for resource usage Thanks for any help.

Combining history of pages which are parts of the same document

by Lijour, Marc (EDU)

Hi I am sure somebody encountered the same problem before. I am working on long documents, this is why I split them in 3 or 4 parts. Later on, I assemble them to print them of to view them (includeTopic() is good for that). But now I would like to get a diff between a complete version of an old document and a new one. What would be the simplest way to achieve this result in your opinion? I don't know the history api well enough to think of something definitive. But what if I could list all revision dates of all the parts documents twice in 2 columns, and then pick the old in the left and the new date in the right (eg. as radio buttons)? I would see the combined history computed this way: - compute rev date for each part document . If the date matches keep it, otherwise use the next existing date in the timeline - generate the "old" document by merging part documents for the respective dates computed above - in moreless the same way, generate the new document - use xwiki $doc.getContentDiff(old, new) to generate the big diff Alternatively, - combine the history pages for each one of the part document as an interface - modify (reuse) the xwiki code that creates the page above to have the user choose a revision date for each one of the parts. Then the user clicks a big button which calls the existing diff mechanism for each parts and then assemble the diff for the user to see. Is that doable? Marc Lijour

Hi Is there a way to embed groovy code into a velocity macro? I am trying to do some string manipulation with groovy pattern matching/replacement. If there is a better way let me know! Thank you.

Migrating from hsql to MySQL

by Lijour, Marc (EDU)

Hi I have been using a wiki running on jetty and hsqldb. Now, I would like to move the data (the whole wiki) to a stable repository. I have been thinking of MySQL. What would be the easiest route to migrate the wiki?
