How could I fix the Chinese problem£¿
by boreal.mao＠gmail.com 23 May '06

23 May '06

I have setup a xwiki in my computer. But failed to input Chinese into it. I changed the charset of these 3 files: web.xml xwiki.cfg velocity.properties and changed the default charset of MySql to gb2312 or gbk, I succeeded in writing Chinese into database but when reading Chinese out of MySql there is an error. UTF-8 couldn't work either, both in reading and writing. Could anyone tell me what to do? Thanks.

Choosing final projects for the Summer of Code
by ludovic＠xwiki.com 21 May '06

21 May '06

Hi, Google just gave the tentative allocation for project. It turns out we will get 4 projects. I hoped for more put given the 626 students allocated (this is already 3M$ by Google) and the 105 Open Source organisation participation, this is kind of normal. We will have to make some tough choices. The current list I created was: User Interface (Implement the ergonomic study) P2P (allow offline usage and P2P XWiki hosting) AJAX API, Toolbar and Form Editor (it can be one of them or all) AntiSpam features JCR backend Editor Completion GData backend We would have to choose 4 and order the last 3 (in case we get additional projects at the last minute). Go ahead and give your opinion before tonight since we have to give the final answer before tomorrow morning pacific time. Ludovic

Error running JDBC batch upload when accessing XWiki
by Weng Kong Lee 20 May '06

20 May '06

Hi all, I'm trying to set up XWiki 0.9.840 on Tomcat 4.1.31 and MySQL 5.0.12. I've deployed the WAR, ran the SQL script against my SQL database, and modified hibernate.cfg.xml to point to my XWiki database. When I ran the main URL I got the following errors: javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3201 in 3: Exception while saving document XWiki.XWikiPreferences Wrapped Exception: Error number 3221 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: Error number 3222 in 3: Exception while saving class XWiki.XWikiPreferences Wrapped Exception: Could not execute JDBC batch update org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:516) org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:423) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:226) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397) javax.servlet.http.HttpServlet.service(HttpServlet.java:689) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:127) Any ideas what might be wrong here? Apppreciate any suggestions! Thanks!

Renaming docs
by THOMAS, BRIAN M (SBCSI) 18 May '06

18 May '06

There have been a number of questions about renaming documents in XWiki, and the usual answer has been that you can't. There is, however, a method, com.xpn.xwiki.doc.XWikiDocument.rename(String, XWikiContext) that purports to do exactly this, and from the source, it looks like it does the correct stuff, cloning itself, updating any objects it contains to refer to the new document name, etc. The only problem with this method is that, in my case, I haven't been able to make it work. In one case, it returned, as advertised, a Document with the new name to my page, but the document remained intact under its original name and not under the new one. Since that time, after which I restarted the server, it only returns null. Due to problems with CGLIB-generated class files, I can't set a breakpoint to find out why (anyone know the magic to make CGLIB create line-number entries?). A few details: the actual problem I'm trying to solve is scripting the change of existing login IDs to integrate with an enterprise-wide authentication service, which requires a company-standard naming scheme. My change to the security scheme was limited to subclassing XWikiAuthServiceImpl and overriding only the default constructor (to instantiate the auth service client library) and the checkPassword method. Since XWiki's default implementation of a user ID is the user's profile, named XWiki.<username>, that will entail changing a document name and all wiki references to it. My first plan was a transitional scheme that involved using XWiki.copyDocument() to create the new document, leaving the original document in place for the default XWikiAuthServiceImpl to use, replacing its content with a notice of the change and removing the user's edit right, then removing it and changing all wiki references to it the first time they log in under the new scheme. Alternatively, using XWiki.createUser to create the new user was a possibility, but it looks messier from the standpoint of migrating the original user's profile page. So, a couple of questions, for discussion and/or authoritative answer: - Does XWikiDocument.rename() actually work as advertised? I am aware of the need for the "programming" right on the original document to use the necessary methods (on the space or the wiki doesn't do it), and have made sure that I have them by checking with checkProgrammingRights. - What's the best way to change an existing user's login ID without disruption beyond having to use the new name? - XWiki provides reasonable ways to find all of the kinds of document references that I can think of, including object string fields(especially group membership and rights objects) and wiki links; are there any others I will need to consider? - Does the XWikiAdmin identity (or the XWikiAdminGroup, for that matter) have any implementation outside the database? I notice that XWikiAdmin's profile document is not named XWikiAdmin, so something is not the same about it. The reason I need to know is that it won't work under the new authentication service's naming rules, and I want to eliminate it for other reasons too (mostly that it's a shared ID) and replace all of its rights entries with a group entry for XWikiAdminGroup. Primarily, I need to know whether there's any reason this strategy won't work, because re-implementing it would constitute an access backdoor. Brian M.

Non-Threadsafe problem...
by tjdove＠hotmail.com 17 May '06

17 May '06

I noticed that someone said that there would be a fix for this in a future release, but is there a workaround for this? I am getting these same exceptions on two different machines with different MySQL/Tomcat versions. Exceptions: >an assertion failure occured (this may indicate a bug in Hibernate, but is more >likely due to unsafe use of the session) >org.hibernate.AssertionFailure: possible nonthreadsafe access to session Thank you, Tim Dove

Group containing all users, dilemma
by Tchize 16 May '06

16 May '06

Hello again, I need in my wiki this configuration xwiki level: everything is restricted to admins namespace X: everyone (connected or not) has read access. Problem: If i put nothing at namespace X level, nobody except admins can read documents If i define read access at namespace X level, i need to know what i have to put in user/group to define 'anyone' You could of course tell me to use a combo of guest and XWiki.XWikiAllGroup, but unfortunately, our user are not created using the registration interface. They are mapped to an ldap server. So the XWiki.XWikiAllGroup stays empty. Unless, of course, this is a virtual group which says always true when asked if xyz belong to it. But it doubt it's virtual :) So, what are suggestions about this? regards, Tchize

RE: [xwiki-users] RSS feed for an individual page?

Hi, It worked for me also, many thanks Robin. I just had to correct something in the code, in the link: instead of "viewrev" as action I replaced with "view" because action viewrev was not understood in my wiki (0.9.840).
