[xwiki-users] Getting user name with a Java Component
by Bryn Jeffries 28 Nov '14

28 Nov '14

What's the right way to get the current user from the execution context within a Java component? Taking the example from the guide (http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents) I thought it would be something like the following, which won't compile for me due to the getLocalUser symbol not being found. import org.xwiki.context.Execution; import org.xwiki.context.ExecutionContext; ... @Inject private Execution execution; @Override public String sayHello() { ExecutionContext context = execution.getContext(); String user = context.getLocalUser(); return "Hello " + user; } I note that in http://nexus.xwiki.org/nexus/service/local/repositories/releases/archive/or… the getLocalUser() method is deprecated in lieu of getUserReference() but I'd really rather deal with a String if at all possible.

[xwiki-users] Migration from 5.4.5 Standalone to 6.3 Tomcat
by D R 28 Nov '14

28 Nov '14

Hi, in our company we used the standalone version of XWiki for testing and are very satisfied with it so we want to migrate to the new version and a more robust setup. The setup is Windows Server 2003 R2 (sadly only 32 bits) with Apache 2.4, MySQL 5 and Tomcat 7. XWiki 6.3 is setup now including a Wiki Template so I'd like to migrate the data I exported as XAR from the 5.4.5 standalone instance. My approach was exporting data from 5.4.5, creating the Wikis using the template and importing the spaces and pages from the XAR export. The issue I'm facing is Java heap size which constantly gets in my way. As we're on a 32 bits system I can only assign ~1.2 GB of memory (the server has 4GB). This limitation makes it impossible to import the data into the new setup. I tried general export/import via administration page and the various options using the Admin Tools Application but on one of both ends I always get the out of memory error. - Using normal export/import: Export works but import throws the error - Admin Tools - Export pages and spaces: Export works but import throws the error - Admin Tools - Large Export on Disk: the heap size error is thrown Do you have any suggestions/hints on how I can migrate the spaces and pages I have in the 5.4.5 setup to the 6.3 one? Thanks in advance, Dennis

So instead of Page name we would like to show: Subject You have 3 options: (1) Use Velocity to output the value of the subject property in the FAQ title. See https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi… Gerritjan: Thanks this is helpful but see below.... (2) I doesn't make sense to have a separate String property to store the subject when you can store it in the document title. The designer of our FAQ has opted to store multiple objects of same class in one page. (because XWiki does not support "multiple locales (language-country)" on a object level. So the title must pick the subject name of the object of the current language-country combination. When we just display the subject we do not need to solve this challenge. (3) Customize the entire search page just to change the way the search results are displayed Yes I fear there is no way around this? As facets we would like to show Topic-group and Language, Default (on entering the page with search box) we would like to set the context-language as a search filter... So when reader is reading french the result only shows french FAQ (with a french subject title) if english only english. By checking and unchecking languages in the facets the user could extend or reduce the search. This is already the case with the default search. The context language is checked by default in the locale facet. See https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi… . It looks the context language is only looking at language attribute of page. We need to compare with attribute in object. I think it would be useful if some explanation is how the object-based facets can be defined. A challenge is the topic field, this is a list with translation key. So if user is french-language the list will show french topics, but if he/she check english as well in facets things get complicated. We have a business-rule that the english collection of FAQ's is the baseline, and most comprehensive. The other languages are only translations of the same. So another languages can not have a question not translated. So my question is: How to define the search http://extensions.xwiki.org/xwiki/bin/view/Extension/Solr+Search+Applicatio… http://design.xwiki.org/xwiki/bin/view/Design/SolrSchema http://extensions.xwiki.org/xwiki/bin/view/Extension/Solr+Search+Query+API http://lucene.apache.org/solr/ How to modify the output so page-title is no longer showing How to modify facets so only the two fields can be set See https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwi… .This helps...

[xwiki-users] Mocca Calendar Application 2.2.1 released - with a glitch
by Clemens Klein-Robbenhaar 28 Nov '14

28 Nov '14

To folks who have the "Mocca Calendar"[1] application installed in their XWiki instances: I have just released a new version 2.2.1 to which you might want to update to, as it contains quite a few bugfixes and improvements, thanks to patches send in by several contributors.[2] However the new release does not show up when you try to update via the "Extension Updater" in your wiki admin; instead the latest version found there will be 2.1.9. This happened due to a glitch when reorganizing the code which changed the Extension-Id for that application. Instead please go to "Add extensions", search for "Mocca Calendar" and when the search result comes up, the extension manager should propose you to update to the correct version 2.2.1 Also while upgrading at least in my test instances I got a few spurious conflicts. If you get them too, even while you have made no modifications to the "code" part of the calendar, please choose to keep the new version to get all updates installed property. Best regards and sorry for the hiccup, Clemens [1] http://extensions.xwiki.org/xwiki/bin/view/Extension/MoccaCalendar [2] http://jira.xwiki.org/browse/MOCCACAL-32?filter=13491

[xwiki-users] Xwiki / accessing external SQL database / How to use SQL plugin ?
by mh＠ow2.org 27 Nov '14

27 Nov '14

Hi, We are looking for the best way to access an external SQL database using velocity exclusively (because we can't write a macro using groovy language). So, we installed and tried to use this plugin : http://extensions.xwiki.org/xwiki/bin/view/Extension/SQL+Plugin. The plugin is properly installed. Now we are unsure how to use it : there is no mention of the user which is used to connect to the database, do we have to to configure a JNDI ? How ? As a side question, what is you guys your preferred method to program xwiki pages with external database access ? Thanks -- Martin

[xwiki-users] Can't delete attachment
by D R 27 Nov '14

27 Nov '14

Hi, I imported several .xar files from another xwiki instance and afterwards wanted to delete the uploaded .xar files. All but one have successfully been deleted. Everytime I delete "Xwiki_New.xar" from the import screen inside the administration screen and refresh the page it's there again. Also in document index I still see it in the attachments tab and not in the deleted attachments tab. Any hints? Is it safe to simply delete it from xwikiattachment table in the database with phpMyAdmin? My system is Windows Server 2003 R2 with Apache 2.4, MySQL 5, Tomcat 7, XWiki 6.3. Thanks in advance, Dennis
