RSS feed/cache question
by KIDWELL, REX (SBCSI) 24 Mar '06

24 Mar '06

Can someone provide information on how RSS feeds and the Xwiki cache system work together? What's known so far. 1) The xwiki/WEB-INF/xwiki.cfg file contains the following lines xwiki.store.cache=1 xwiki.store.cache.capacity=100 2) Based on the build.xml file included in the source, xwiki is configured to use ehcache-1.1, oscache-2.0.2, and swarmcache. 3) grep results on source files indicate that OSCache is being used by Xwiki. Questions 4) Does item 1) mean caching is enabled for RSS feeds? 5) Does "xwiki.store.cache.capacity=100" relate to OSCache's "cache.capacity" configuration property? Are they the same? See the following URL http://wiki.opensymphony.com/display/CACHE/Configuration 6) Please confirm that OSCache is being used by Xwiki 0.9.840 for RSS feeds That's enough, for now and thanks for any help you can provide.

[xwiki-users] Plain text "select x into y" in any document breaks xwiki.com
by Robin Fernandes 24 Mar '06

24 Mar '06

Hi, Trying to view/preview any page on free xwiki.com hosted containing the text: select x into y causes nothing more than the following message to be displayed: We are currently doing performance maintenance of our servers. The service will be back in a few minutes. Sorry for the inconvenience. 'x' and 'y' can be any number of words. Note that this happens with plain text - no velocity or anything, e.g. simply a document containing the text: Press the 'add' button to select which plugin is loaded into the current effect slot. I haven't raised this as bug on JIRA since I can't reproduce it outside of xwiki.com hosted wikis. So I guess it's some configuration issue or some extra protection gone wrong on xwiki.com. Thanks, Robin.

How to use IPResolverPlugin
by Julien Bourdon 24 Mar '06

24 Mar '06

Hi all! I'm a newbie in XWiki application development and I'm trying to make sense of these plugins. I tried with the IPResolverPlugin which looks quite simple but I don't know how to access it from the Velocity context. Is this possible at least? Thanks a lot! -- _ _ Julien Bourdon (o)(o)--. http://purl.org/net/JulienBourdon \../ ( ) self isAddictedTo:(#Squeak&#linux) m\/m--m'`--. ^true

LDAP Integration
by Christian van der Leeden 24 Mar '06

24 Mar '06

Hi, just testing the LDAP integration on a development build (head). I do manage to authenticate against my LDAP server and I'm logged in afterwards, but the username is not displayed (only: $docuser.display("first_name", "view", $objuser)) and somehow I'm not really "logged in". I don't have the permissions I normally have, when I'm a logged in user. Do I have to do anything extra for the LDAP integration? Do I have to create each user which exists in ldap also in the xwiki db? (this apparently works..) Below my xwiki.cfg Christian xwiki.cfg for ldap: xwiki.authentication.ldap=1 xwiki.authentication.ldap.server=enron xwiki.authentication.ldap.check_level=1 xwiki.authentication.ldap.base_DN=dc=LogicUnited,dc=Com xwiki.authentication.ldap.bind_DN=cn=Manager,dc=logicunited,dc=com xwiki.authentication.ldap.bind_pass=**** xwiki.authentication.ldap.UID_attr=uid xwiki.authentication.ldap.fields_mapping=name=uid,last_name=sn,first_name=givenName,fullname=cn,mail=mail,ldap_dn=dn -- ------------------------------------------ Logic United GmbH Email: leeden(a)logicunited.com Tel: +49-89-189488-66

[xwiki-users] added some hql velocity examples in dev guide
by Robin Fernandes 24 Mar '06

24 Mar '06

I have written up some very simple velocity+hql examples in the dev guide: http://www.xwiki.org/xwiki/bin/view/DevGuide/velocityHqlExamples Perhaps this would turn into a more elaborate tutorial as we get answers to brain[sic]'s questions. :)

Huh... Sounds intriguing, but I'm puzzled about a lot of details, like: how do you do that? Probably an example would be very useful.

HQL question (wasRE: [xwiki-users] SQL hair-pulling)
by THOMAS, BRIAN M (SBCSI) 24 Mar '06

24 Mar '06

Would this perhaps be why I can't use an arbitrary expression as a result field? Specifically, my query for objects less than a week old used the SQL expression: subdate(curdate(), 7) which worked fine when used in a comparison to a date field in the WHERE clause, but provoked an error when I tried to use it in the column-list, which is (I believe) clearly legal SQL syntax. If this were a feature that HQL simply didn't support, it would explain the problem. Indeed, that is what the error message seems to say: Error number 4001 in 4: Error while parsing velocity page Brian.WorkPagesTest Wrapped Exception: Invocation of method 'search' in class com.xpn.xwiki.api.XWiki threw exception class com.xpn.xwiki.XWikiException : Error number 3223 in 3: Exception while searching documents with sql select subdate(curdate(), 7), prop.value, [...] where [...] or subdate(curdate(), 7) <= prop.value ) [...] Wrapped Exception: No data type for node: org.hibernate.hql.ast.MethodNode +-METHOD_CALL?

Jérémi: Aha! I should have read my mail before sending my last note, which I began composing last night. That clears a lot of the mystery. I will save my other questions until after I've read your reference; thank you. But it re-raises for me the issue I had thought resolved - that of where the boundary of queryability may be. I had assumed that it was the same as the boundary of the XWiki-defined object model, as it would seem logically if it had to be supported as a database map, but since it's a general-purpose persistence tool, might that assumption be wrong? Probably, any queryable object would have to be modeled in the database, but it's a grey area in my understanding. I do note that date fields are returned as java.sql.Timestamp rather than as java.util.Date, in case that has any bearing on the matter. brain[sic] -----Original Message----- From: jeremi joslin [mailto:[email protected]] Sent: Thursday, March 23, 2006 10:47 PM To: xwiki-users(a)objectweb.org Subject: Re: [xwiki-users] SQL hair-pulling On 3/24/06, THOMAS, BRIAN M (SBCSI) <bt0008(a)att.com> wrote: > As mentioned in an earlier message, I got into the $xwiki.search() > world yesterday, and am thoroughly confused. > > The main problem seems to be that the XWiki database schema and the > schema used in all of the $xwiki.search() queries I have found are > completely disjoint. > > Instead of the documented tables and columns, what seems to be used is > a schema which reflects the object model within XWiki.

SQL hair-pulling
by THOMAS, BRIAN M (SBCSI) 24 Mar '06

24 Mar '06

As mentioned in an earlier message, I got into the $xwiki.search() world yesterday, and am thoroughly confused. The main problem seems to be that the XWiki database schema and the schema used in all of the $xwiki.search() queries I have found are completely disjoint. Instead of the documented tables and columns, what seems to be used is a schema which reflects the object model within XWiki. This would really be convenient if true; is it? brain[sic]
