Re: [xwiki-users] datetime in xwiki rss feeds
by Sudhir Rao 22 Jun '06

Actually I saw that code. The simplest fix I could figure was this... In the page http://.../xwiki/bin/edit/XWiki/WebRssCode, I replaced this line <dc:date>$currentdoc.date</dc:date> with <dc:date>$xwiki.formatDate($currentdoc.date, "yyyy-MM-dd'T'HH:mm:ss")</dc:date> The fix however omits the timezone. There is java code at http://www.dpawson.co.uk/relaxng/schema/datetime.html which handles the timezone as well. The SimpleDateFormat pattern "yyyy-MM-dd'T'HH:mm:ss.SSSZ" is close as it gives 2005-06-29T17:20:46.171-0800 This however does not work because of the missing colon. It needs to be 2005-06-29T17:20:46.171-08:00 The simplest way seems to be to use commons-lang utilities DateFormatUtils.ISO_DATETIME_TIME_ZONE_FORMAT.format(new Date()) Since commons-lang is already part of the distribution is there a easy way to add this code? I just don't know how to incorporate it in here at this point due to unfamiliarity with velocity, groovy etc. Thanks very much. regards Sudhir On 6/29/05, Ludovic Dubost <ludovic(a)xwiki.com> wrote: > > Yes..

MySQL communication link failure
by Stéphane Laurière 10 Oct '05

10 Oct '05

While trying to upgrade an XWiki installation from 0.9.793 to 0.9.840 I face a MySQL connection problem. My server config: ======= MySQL 4.1.12 Tomcat 5.5.9 JDK 1.5 Mandrake Linux virtual server kernel 2.6.9-vs1.9.3 XWiki runs in non virtual mode URL: http://www.edos-project.org ====== XWiki 0.9.793 works perfectly on that server since a while. When trying to run the 0.9.840 version with the same Hibernate and XWiki configuration files, I get the exception below. MySQL "skip-networking" option is correctly set in /etc/my.cnf. I noticed that the error appears in some of previous XWiki build reports such as this one: http://build.xpertnet.biz/cc/buildresults/xwiki?log=log20050628171819Lbuild… Any hint is welcome! Note: getting a simple connection to MySQL with the lines below works perfectly fine on the server. ====================== String url = "jdbc:mysql://localhost/xwiki"; String username = "xwiki"; String password = "passwd"; Connection conn = DriverManager.getConnection(url, username, password); ====================== Exception when running XWiki webapp: 21:32:16,675 WARN http-80-Processor25 http://www.edos-project.org/xwiki/ Configurator:configure:126 - No configuration found.

template for faulty URL references
by David V. Kocher 01 Oct '05

01 Oct '05

Is it possible to define a page template for references to non- existent articles? (as in many other wikis, e.g. mediawiki > http:// en.wikipedia.org/wiki/NonExistantPage ) The behavior on xwiki.org itself is not consistent; e.g. http://www.xwiki.org/xwiki/bin/view/Main/null shows an empty page whereas http://www.xwiki.org/xwiki/bin/view/null gives a stacktrace. ~dk

Authoring template vs. rendered view
by Yves Langisch 01 Oct '05

01 Oct '05

Hi all, I'm having troubles to separate the editing/authoring view from the normal view. When creating a new object instance I'd like to have a completely different authoring form from the later read-only view. When I'm right a sheet and a template per class should help separating these two things?!? I also played around with the FAQ sample application (http://www.xwiki.org/xwiki/bin/view/DevGuide/FAQs +Tutorial) but without success. The problem seems to be that the when creating a new document the template content is copied into the new document and is used for both editing and viewing. Do I get anything wrong? Thanks Yves

groovy in vm templates
by Matthew Conway 30 Sep '05

30 Sep '05

Is it possible to have groovy script in the "*.vm" templates that are in a custom (or default) skin? I tried adding some groovy script, but the script just got echoed verbatim to the output html. I have no problem adding groovy to an xwiki document. Matt

xwiki production ready?
by Yves Langisch 28 Sep '05

28 Sep '05

All, I have a few questions concerning the readiness of xwiki for production: - how 'production-ready' is xwiki in the actual version? - are there any known issues which can affect the production (load, leaks, ...)? - there are links which generates a stack trace (e.g. http://www.xwiki.org/xwiki/bin/view/Mai ) . Is there a way to define a general error page so that any stack trace is caught by this page (and can be hidden)? Thanks Yves

Tables and readable xwiki code
by Rodrigo Paes 27 Sep '05

27 Sep '05

Hi all, I know that this question is not a functionality question, but it affects directly the usability of Xwiki, especially to convince non-programmers to use wiki. Then, here it goes: Using the xwiki syntax to build tables, I find the resulting code a little unreadable once it is not allowed to insert line breaks. I tried to insert HTML comments to solve the problem, but it did not work. I put the code just below to illustrate my point. Is there any way for doing something like the third way? a) How it is: {table} Header 1|Header 2 A value|A Value A value|A Value A value|A Value {table} b) the way I tried: {table} Header 1|Header 2 A value|A Value  A value|A Value  A value|A Value {table} c) how I would like to see: {table} Header 1|Header 2 A value|A Value A value|A Value A value|A Value {table} Rodrigo Paes PHD Student - Computer Science - PUC-Rio - <mailto:[email protected]> rbp(a)les.inf.puc-rio.br Messenger - <mailto:[email protected]> r0drigopaes(a)hotmail.com Web-page: <http://www.teccomm.les.inf.puc-rio.br/rodrigo/> http://www.teccomm.les.inf.puc-rio.br/rodrigo/ "Só existem duas certezas na vida: a morte e os impostos"
