Hi Nebil, Do not send a mail to one list's member but directly to the list: xwiki-user(a)objectweb.org I never use Geronimo and I can't help you, but other people in the list may can.

Upgrading (HSQLDB)
by Marc Lijour 27 Dec '06

27 Dec '06

Hi The quickest way to upgrade a xwiki installation running on jetty+hsqldb would be to unzip and to overwrite all files under db/ with the "old ones". But does it work like that? For example, I have a 0.840 and a 0.1252. I want to move them to the latest svn. Do I lose something if I overwrite the files this way? Thank you. Marc

Possible bug in import
by Paul Armstrong 25 Dec '06

25 Dec '06

I think I've found a bug in the import system (xwiki/bin/import/XWiki/Import). XWiki: 1.0-beta-1 Java: 1.5.0_07-b03 Tomcat: 4.0.5 If Tomcat is running as an unprivileged user and I try to import an XAR file I get a stack dump. Tracing this shows the file it's trying to write to is /upload__2d1b026e_10fac18a3a1__8000_00000008.tmp As Tomcat has a working directory of /, this doesn't work so well. CATALINA_TMPDIR is set to /var/tmp so I expect this is where it should write to (this should be ${java.io.tmpdir}). Tracing through FileUploadPlugin.java, lines 128-134 have: if (tempdir != null) { fileupload.setRepositoryPath(tempdir); (new File(tempdir)).mkdirs(); } else { fileupload.setRepositoryPath("."); } so I suspect that whatever is calling loadFileList is failing to set the tempdir and it's defaulting to ".". I tried to trace this back but was unable to work out where it came from (the context stuff confuses me). Here's the stack trace printed: Error number 0 in 11: Uncaught exception Wrapped Exception: null com.xpn.xwiki.XWikiException: Error number 0 in 11: Uncaught exception Wrapped Exception: null at

Sporadic exceptions uploading an attachment
by Peter Flynn 22 Dec '06

22 Dec '06

We are seeing this exception pretty often while uploading attachments (but not all the time). The file is not uploaded successfully after seeing this error, but trying again right afterward usually works fine. Still, we would still like to get to the bottom of this. Anyone have suggestions? - Peter Error number 0 in 11: Uncaught exception Wrapped Exception: null com.xpn.xwiki.XWikiException: Error number 0 in 11: Uncaught exception Wrapped Exception: null at

[xwiki-users] accessing & altering objects/class values
by Jeff Ousley 22 Dec '06

22 Dec '06

Hello, I'm trying to do something I thought was simple, but I'm not figuring it out. I've got a page in my space called "test". Associated with that page is an object called "TestClass". TestClass has one field/property called "num1" which is of type long and currently set to 333. Now, I want to write the velocity code to simply get the value of num1, add 1 to it, and store it again in the num1 field so the next time I read it, it should have a value of 334. Can this be done? Any help is appreciated. Thanks, -jeff

Multiple Xwiki containers on same Tomcat installation
by Esbach, Brandon 22 Dec '06

22 Dec '06

Hi guys, Looks like this isn't supported anymore.. On my installation of XWiki10B1, links created using [(space).(pagename)] always generate an URL pathed to "/xwiki/bin/view/(space)/(pagename)", instead of "bin/view/(space)/(pagename)". As I cannot use multiple xwiki virtual containers (not permitted by our IT Policy), this puts me in a bit of a problem.. Any way around this without extensive reworking? Or alternitively, is there any way to change the "Home" designation for a group? So that if they are part of a specific group, they get a different "Main" space (for login, clicking on the Logo, etc).

Can you let us know which version of xwiki you downloaded? You may consider using the 1.0 beta from there: http://www.xwiki.org/xwiki/bin/view/Main/Download It includes a complete standalone intaller. Note that XWiki also contains a blog application. You can see it in action there: http://www.xwiki.org/xwiki/bin/view/Blog/ In your case, the console displays "Could not create a DBCP pool": it means your XWiki instance cannot connect properly to the database. You should probably check that the MySQL account declared in the file $XWIKI_INSTALL/WEB-INF/classes/hibernate.cfg.xml (properties "connection.username" and "connection.password") is correct. Sending the output of Jetty log file may help. Cheers Stéphane

Internationalization

Hi all. While xwiki looks good to me in general, I was somewhat disappointed to see "CHARSET=latin1" in dump for 1.0-beta-1. I want to set up wiki in russian and wondering if/when full out of the box I18N support is planned for general availability. Can anyone comment on this? Thank you, Pavel

Admin rights
by Daniel Marre 21 Dec '06

21 Dec '06

Hello, Waiting for some solution under Debian and having some "chidren excitation" in this Christmas period, I installed Xwiki on my Mac OS X top lab, allways with the standalone distribution to discover the tool. It runs well ... congratulation for all developpers ! It's a very nice tool. I try some editing features but I have a problem when try some Admin features with the Admin password ... what is it ? The access to some Admin Guide part are requiering also the Admin passwd .... (the configuration part for example) (this passwd is allso required on Xwiki site Admin Guide -> Configuration ) thank's you for help.

On-The-Fly/Generic Permission
by Esbach, Brandon 21 Dec '06

21 Dec '06

In version 0.9.840 there was the ability to generically add a permission as required; by putting any selected text in place of "view/edit/programming/etc". This has worked quite well for us to date on the older version. I guess the question would be, is there a way to add to the permissions list on XWiki1B1? Part2, related query: Is there a way to show a specific panel depending on your permission? For example, if the user is an administrator I'd like to show an Admin Panel; or if the user has Workflow rights I'd like to show a panel with Workflow features. While I know I can protect the content of a panel by checking certain values (permissions/etc); this would still mean that an empty panel is shown for the user.
