Yes. The problem is that no mail gets sent, which is the purpose of the notification. I reread my initial post, and now I understand your confusion. I didn't explicitly state that the class wasn't working. I'm using XWiki Enterprise manager 1.3 with platform version 1.5.2.

Re: [xwiki-users] Clean URL and WYSIWYG Issues

by RBrennanJr＠boston.com

I ran into the same issue Jonathan mentioned the other day with wysiwyg/wiki editor after applying servlet mapping changes etc to get 'Short URLs' working. There appears to be 2 solutions, one is that you have to adjust servlet mappings for all directories & .js files at the top level (*.js, tiny_mce, wiki_editor, yui) in order for everything to play nice together. A work around I've found if you don't want to do that (or have easy access to it) is that everything does appear to work if you move those directories under /skins/ & adjust the references to those files, in javascript.vm & editwysiwyg.vm (there may be a couple other references ...) I'm using a custom skin built on top of the defaults, which has the advantage that I can have my own versions of those files & not have to worry about changing paths to those js libraries in the default skin files upon future upgrades. I'm undecided which the better method is (servlet mapping vs. moving those dirs), but in either case, this might be good info to add to the Short URL instructions - unless Jonathan & I are the only ones who have encountered this , in which case, not sure where we went wrong in our respective configurations :-) Incidentally, the adaptation of XWiki I'm working on is a pilot product for www.boston.com (http://www.boston.com/yourtown/wiki/Newton/ - not quite ready for prime time however ;-) as we get it more solidified I'll be happy to share with the XWiki community & get more involved - specifically I may be able to contribute some tips & tricks & shortcuts to the custom skin documentation ... Best, Ricky Brennan rbrennanjr(a)boston.com

Indeed, this has nothing to do with your groovy notification. This is generated by the velocity engine. Is your skin customized ? Is the blog application modified ? (The log says that somewhere a variable $index is trying to add something to "null". Might be the pagination of blog articles ?) Jerome. I can't find a variable $index in any arithmetical expression in any velocity script anywhere on the site. The skin is customized only to the extent of some inconsequential tweaks. Same with blog app. There's no pagination of blog articles. Would someone please review the basic mechanics of how groovy classes work, particularly as it pertains to my notification class? Also, I see by reading source that there's a newer way of monitoring events through the "observation manager". Would someone please review how to use this system? Thanks, Dan

[xwiki-users] Admin avatar/picture change

by Daniel Simon

How can the admin (or other user with admin privileges) modify another user's picture/avatar? The only way that I've found of doing this is attaching a file to the user page and editing the XWiki.XWikiUsers "avatar" class item manually. It looks like the regular avatar upload page doesn't work properly for anyone but the user in question. /DS

[xwiki-users] OutOfMemory errors.

by Robert Munro

Hi I have been running xwiki on a hosting server with 128Mb private JVM for a few weeks with no problems - but all of a sudden today i seem to be getting OutOfMemory errors whenever I try to run the app (i.e. go to the main page). Is there any links / advice for performance tuning - i was reading something about the attachment cache taking lots of memory (I would be happy to disable this cache). What would be the recommended memory for running xwiki? It all seems strange as i have been running it for 3 weeks with no probs, I have other hibernate apps but they are running fine. reagrds, rob.

[xwiki-users] authentication

by Dan Svoboda

How does one generate new key/value pair for form based authentication? i.e. new values for; xwiki.authentication.validationKey=totototototototototototototototo xwiki.authentication.encryptionKey=titititititititititititititititi Will anything else have to be changed after changing these values? Also, what is the meaning of: xwiki.authentication.cookiedomains=xwiki.com,wiki.fr Should this be set to my own domain? Cheers.

[xwiki-users] groovy notification

by Dan Svoboda

Hi, I'm trying to use the notification system to trigger the sending of email whenever a comment is added to a blog article. I'm patterning my groovy class after the pircbot example on the xwiki snippets site. My system is xwiki workspaces as a virtual xwiki under xem. The platform version is 1.5.2. Here's my groovy class (XWSNotify.BlogMailNotificationGroovyClass): /* Groovy Class #* */ import com.xpn.xwiki.api.XWiki; import com.xpn.xwiki.XWikiContext; import com.xpn.xwiki.notify.XWikiDocChangeNotificationInterface; import com.xpn.xwiki.notify.DocObjectChangedRule; import com.xpn.xwiki.notify.XWikiNotificationRule; import com.xpn.xwiki.doc.XWikiDocument; public class BlogMailNotificationGroovyClass implements \ XWikiDocChangeNotificationInterface { def xwiki; def rule; def name; public void initClasses(XWikiContext context) { this.xwiki = context.getWiki(); // listen to notifications this.rule = DocObjectChangedRule(this); context.getWiki().getNotificationManager().addGeneralRule(rule); } public void notify(XWikiNotificationRule rule, XWikiDocument newdoc, \ XWikiDocument olddoc, int event, XWikiContext context) { def length = newdoc.getSpace().length(); def lastFour = length - 4; if(newdoc.getSpace().substring(lastFour) == "Blog") { def ms = xwiki.getPlugin("mailsender"); def nb = ms.sendHtmlMessage(context.getUser(), "myAddress(a)myHost.org ", \ context.get("ccrecipients"), context.get("bccrecipients"), \ context.get("subject"), newdoc.getRenderedContent(), \ newdoc.getContent(), newdoc.getAttachments()); } } } /* *# */ Here's a velocity script I'm using to initialize/test: #set($sc = $context.getContext().getEngineContext().getServletContext()) $sc.getAttribute("blgmailnotif") #set($blgmlnotif = $xwiki.parseGroovyFromPage("XWSNotify.BlogMailNotificationGroovyClass")) #set($ok = $sc.setAttribute("blgmailnotif", $blgmlnotif)) #set($blgmailnotif = $sc.getAttribute("blgmailnotif")) $sc.getAttribute("blgmailnotif") #set($ok = $blgmlnotif.initClasses($context)) #set($ok = $blgmlnotif.notify($blgmlnotif.rule,$newdoc,$newdoc, 3,$context)) Here's the output from the velocity script: BlogMailNotificationGroovyClass@68e4a47 BlogMailNotificationGroovyClass@3c401d45 So, the groovy class gets initialized to a new reference successfully each time parseGroovyFromPage is called. Here's what appears in the log after running the velocity script: [ERROR] Left side ($request.title) of '!=' operation has null value. Operation not possible. [line 53, column 43] [WARNING] Cannot retrieve method notify from object of class BlogMailNotificationGroovyClass due to security restrictions. If I alter the velocity script to: #set($sc = $context.getContext().getEngineContext().getServletContext()) $sc.getAttribute("blgmailnotif") Here's what appears in the log: [ERROR] Left side ($request.title) of '!=' operation has null value. Operation not possible. [line 53, column 43] So, the [WARNING] is the only log entry pertaining to the groovy class. If I add a comment to a Blog article (with or without the BlogMailNotificationGroovyClass initialized), the following appears in the log: [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] [ERROR] Left side ($index) of addition operation has null value. Operation not possible. [line 20, column 25] The number of lines corresponds to the number of comments present in the Blog article. There's nothing in the log pertaining to the groovy class. What am I doing wrong? Is there a way to put additional groovy debugging information into the log? Thanks, Dan Svoboda University of Pittsburgh Center for HIV Protein Interactions
