[xwiki-devs] XEclipse Navigator was `Re: GSoC : Proposal submitted`
by Venkatesh Nandakumar 31 Mar '09

31 Mar '09

Hi, Could someone please look into my second question, cause I really like to get an answer for that, since I would like to submit my proposal for that too... I guess my previous mail was overlooked upon, in the crowd of other mails. As I've already mentioned, I've submitted my proposal for the "XEclipse Navigator", please look into the proposal, and let me know how I can improve it. The final query was answered, by Guillaume, in another thread; Thanks for that.

[xwiki-devs] New XEclipse Navigator GSoc
by mafaz hassan 31 Mar '09

31 Mar '09

Hi, I am Mafaz Hassan. An undergraduate of Department of Computer Science and Engineering.I am working on submitting a proposal for the Project XEclipse navigator.I have sent mails to this mailing list before, but i was just replying to the common thread which would not have been clear to you all.Sorry for the inconvenience caused.I have four to five years experience on Java and i have a good knowledge on GUI programming in Java.I have been very much involved in Swing Programming in Java for the past one or two years, So I chose the XEclipse Navigator project without much confusion.I have a strong knowledge on XWiki ,XWiki Data Model and XEclipse now.I would like to know more on the state persistence functionality mentioned?I want to know what level of state persistence do you expect out of this project?And can someone help me out in building the source of XEclipse? Thank you. Regards Mafaz

[xwiki-devs] Willing to Contribute Xwiki in Gsoc 2009
by Harsha Halgaswatta 31 Mar '09

31 Mar '09

Hi all I am an undergraduate at University of Moratuwa specializing in the field of Computer Science and Engineering and willing to take part in XWiki during this summer. I participated in Gsoc last year with Sahana community where i involved in implementing a project relating to social networking and i completed it successfully [1] . Where i had to play with photo related works and i extracted more on the methodologies of handling those information. I myself think this project is kind of interesting for me and will be able to contribute you effectively than last years as i am more passionate on FOSS and Gsoc. Further i am really interested in Java projects as most of the projects i have done and experienced are lied on Java.One of them is listed below [2]. Regarding the photo album application i want some more clarifications on migration tool from the old version photo albums. is it kind of extracting features based on the old implementation having their core logics, in new appliaction or just a tool to convert old photo albums to new one with their excisting features. Would you mind clarifying me on this. Further regarding the Import Export from any other Wiki , would it be kind of content transferring mechanism among wikis. In that case i can think in terms of providing a link aside to transfer a selected content on one wiki to another etc. I am glad to have more information on this too.

Re: [xwiki-devs] [curriki-devs] XWiki HQL queries too slow
by Joshua Marks 31 Mar '09

Forwarding this to xwiki devs for input. Joshua Marks CTO Curriki: The Global Education and Learning Community jmarks(a)curriki.org www.curriki.org US 831-685-3511 -----Original Message----- From: curriki-devs-bounces(a)xwiki.org [mailto:curriki-devs-bounces@xwiki.org] On Behalf Of Henri Lesourd Sent: Tuesday, March 31, 2009 9:18 AM To: curriki-devs(a)xwiki.org Subject: [curriki-devs] XWiki HQL queries too slow Although it's not specific to Curriki per se, I start by posting my question here, for perhaps somebody on the list met this problem before. My question is: I need to query documents containing an object from a specific Java class, and to access the object. In Vincent Massol's XWiki tutorial, examples of how to do this are exclusively described in the following way: (1) First, query the wiki for the names of all the documents having a specific class, e.g.: #set ($hql = ", BaseObject as obj where obj.name=doc.fullName and obj.className='XWiki.TodoClass'") for querying the names of all the documents having the class 'TodoClass'. (2) and then, for each document, fetch the document with getDocument(), and then perform a getObject() for getting the related instance of the Java class, which finally can be accessed. Here is a typical snippet: #foreach ($todo in $todos) #set ($todoDoc = $xwiki.getDocument($todo)) #set ($todoObj = $todoDoc.getObject("XWiki.TodoClass")) ........ { Code using $todoObj } .......... #end Problem is: in my version of the step (1) above I get 1800 documents, but next, in step (2), I dismiss most of them by means of performing a simple test on the slots of the object obtained from getObject(). Thus, as it is described above, the technique from the XWiki tutorial is highly inefficient, because for the sake of performing the simple test you need on the Java object contained in each document, you are forced to fetch this document, then read the object with getObject(), and it's only then that you can perform your simple test. ==> Question: is there a possibility to perform the getObject() *inside* the HQL query, in such a way that I can fetch and test the slots of a given related Java object (e.g., an XWiki.XWikiUsers, or an XWiki.XWikiGroups) directly inside the 'where' part of the HQL query ? For example, I'd like to be able to write something like: #set ($hql = ", BaseObject as obj where obj.name=doc.fullName and obj.className='XWiki.XWikiUsers' and doc.getObject('XWiki.XWikiUsers').country='Papua New Guinea')") for fetching the names of the XWiki pages of all people from Papua New Guinea. In such a case, if there are only few of them among several hundreds of users from more common nationalities, I run exactly on the problem described above. Of course, this example with the users is not very useful, and perhaps you can do that in another way from inside Java, but the pattern is typical. In practice, if you cannot perform simple tests to eliminate unwanted items directly inside the HQL, then very easily, you obtain programs performing queries lasting several dozens of seconds, which quickly becomes unbearable for the users. With more users operating in the same time, the response time for a simple Velocity program displaying a list of items can even reach response times of several minutes, like it happened to us last week during the presentation of Intergeo in a seminar in Spain (fortunately, people understand that the system is under development, but...). Thus I'm looking for an approach to eradicate this problem once for all, for otherwise, it will not be possible to build a web-based system usable by more than a dozen users, and this would be, hem, annoying so to say...

by Julien Revert 31 Mar '09

31 Mar '09

Hi, I wrote a java batch allowing to acces XWIKI. This batch was okay with 1.5.2 XWiki release but it's not working with 1.7.1 XWiki release. I don't understand where is my problem and need your help... Here is a part of my java code : ------------------------------------------------------------------------------------------- private ComponentManager componentManager = null; /** * @return a configured Component Manager (which uses the plexus.xml file in the test resources directory) which can then be put in the XWiki Context for testing. */ public ComponentManager getComponentManager() throws Exception { if (this.componentManager == null) { DefaultContainerConfiguration configuration = new DefaultContainerConfiguration(); configuration.setContainerConfiguration("/plexus.xml"); DefaultPlexusContainer container = new DefaultPlexusContainer(configuration); this.componentManager = new PlexusComponentManager(container); } return this.componentManager; } /** * Constructeur de BatchWikiAccess * @throws Exception */ public BatchWikiAccess() throws Exception { String rootPath = Thread.currentThread().getContextClassLoader().getResource("").getPath(); // Recuperation du fichier de proprietes xwiki FileInputStream fileInputStream = getInputStream(rootPath + "xwiki.properties"); XWikiConfig conf = null; try { conf = new XWikiConfig(fileInputStream); conf.setProperty("xwiki.store.hibernate.path", rootPath + "hibernatedev.cfg.xml"); Utils.setComponentManager(getComponentManager()); wiki = new com.xpn.xwiki.XWiki(conf, new XWikiContext()); } catch (Throwable e) { Logger.getLogger(this.getClass()).error("o !!! Pb grave lors du runtime : " + e.getMessage()); throw new Exception("o !!! Pb grave lors du runtime : " + e.getMessage()); } } ------------------------------------------------------------------------------------------- I have a runtime error while execute line : wiki = new com.xpn.xwiki.XWiki(conf, new XWikiContext()); Thanks in advance for help. If someone has a better way to access XWIKI in batch mode; it good to ! Julien

[xwiki-devs] Google gadgets / Google docs integration / Calender Application
by Arosh Perera 31 Mar '09

31 Mar '09

Hi, I'm Arosh. In last few days I go through the Google API and find out the component features and the data model of it. I think this should be the correct project to me for this summer.Because I am a Sun Certified Java Programmer and four to five years experience with Java. Also I have the experience of working with several APIs.In last 6 months I working with mobile APIs like Android and Brew, WAP frameworks like mymobileweb and netbiscuits and also JSF ect. So before I further researching on these projects I think it is very much important to have a strong understanding about XWiki data model.I would like to know what are the relevant steps should I take to make my interest a reality. Further I would like to know what are the weakness that was there in old calender specifically. -- regards Arosh Thilanka Perera Dpt of Computer Science & Engineering University of Moratuwa Sri Lanka.
