xwiki formatting question
by Tim Suter 14 Oct '05

14 Oct '05

In moving content over from our Zope driven site, I have noticed that several times the content of the Zope page creeps into the right margin and pollutes the Search column. Is there a global setting that will change the XWiki format so that it will auto adjust for the content? With the Toolbar editor, I am sure I could remove the whole column, however I don't want to. Just make it allow for content so it will shift to the right automagically. Thanks, Tim Suter

Cookie issue with username length
by Stéphane Laurière 10 Oct '05

10 Oct '05

Hi everybody, I have this issue with usernames: it appears that too long logins prevent users from logging in. What is the actual limit for login names, and is there a way to extend it? As a test I have registered on xwiki.org a user with a username having 100 characters, and they cannot login indeed. Locally I see the user is correctly authentified, but then there's a problem with the cookie. Here's the trace I get: ============== !remember-me cookie validation hash mismatch! !remember-me cookie has been tampered with! !remember-me cookie is being deleted! ============== That's a problem for me as my logins are based on the email address, and some have a length of 100 characters.

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.

Serving stand alone VM files
by Matthew Conway 09 Oct '05

09 Oct '05

Is it possible for xwiki to serve a static VM file that is not associated with a document? That is, serve a url like "/xwiki/ foo.vm" and have the velocity evaluated? As a workaround, I can do something like /xwiki/bin/view/XWiki/DummyDoc?xpage=foo.vm but it seems wasteful to have to query the DB to serve a somewhat static file. Matt

particular page would not save w/o error
by kenk＠ucar.edu 09 Oct '05

09 Oct '05

Hi, I'm using v0.9.842 on tomcat 4.1.31 with j2sdk1.4.2_06 and postgresql 7.3.5: I had been editing and building a page thru the bin/edit function over days without problem, then today it would throw the errors below after every save even tho it still made the changes (most of the time). I tried cutting down the size of the page but finally tried saving a blank page and still got the error so I do not think it was from my mix of wiki syntax and html or html-area generated content that caused the errors. And, during this whole period I was still able to create and edit other pages than the one I had trouble with. I finally deleted the page, and recreated it w/ a different name but same content and it's fine now. I had restarted the db server and tomcat but that had no effect. Does anyone know what this might be? thx in adv -ken here's the generic-looking error: Wrapped Exception: Could not execute JDBC batch update com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while saving document Csdg.WebAppServersAsRPMs Wrapped Exception: Could not execute JDBC batch update at com.xpn.xwiki.store.XWikiHibernateStore.saveXWikiDoc(XWikiHibernateStore.java:540) at com.xpn.xwiki.store.XWikiHibernateStore.saveXWikiDoc(XWikiHibernateStore.java:557) at com.xpn.xwiki.store.XWikiCacheStore.saveXWikiDoc(XWikiCacheStore.java:77) at com.xpn.xwiki.XWiki.saveDocument(XWiki.java:560) at com.xpn.xwiki.XWikiService.actionSave(XWikiService.java:445) at com.xpn.xwiki.web.ViewEditAction.execute(ViewEditAction.java:155) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:226) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:415) at javax.servlet.http.HttpServlet.service(HttpServlet.java:716) at javax.servlet.http.HttpServlet.service(HttpServlet.java:809) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:200) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:146) [snip] ...sorry at this point I can't do a debug.

I'm sure I'm not the only one who's noticed the outage. Maybe it's time to think about migrating back to sourceforge, or using some other system that's a bit more robust?

LDAP Authetication working....but...

I got LDAP Authentication working. However, I cannot log in as the xwiki admin. How do I get that log in AND LDAP working at the same time? Also, I need the LDAP users to have editing capabilities and not just be able to view. Thanks, Tim

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
