Hi developers ! Google has just given the tentative number of projects that XWiki will have the chance to have sponsored under the program. Currently I've ranked the proposals this way.. The 6 proposals that will very probably be accepted 1. A P2P XWiki 2. An Offline WYSIWYG Editor (Java) with code completion etc.. 3. A Powerfull WYSIWYG Editor in DHTML or Flash 4. SVG Charting of XWiki Tables 5. Independent Query API for XWiki 6. An Agile Project Management Application Then the following applications are rejected but I would love to have them done. So we are thinking of making a mini-summer of code proposal and proposing some bounties for it (not as much as Google): 1. SVG Realtime Whiteboard in Java + Mozilla SVG 2. AnyEdit: plugabble realtime editor in Java (text, image, drawing, etc..) 3. Another P2P XWiki proposal 4. Integrate tagging and tag browsing into the XWiki environment 5. Survey and Reporting Tool (the reporting system would be generic) 6. Integrate Servoo with XWiki (OpenOffice and MS Office integration) 7. Google Maps Integration 8. A Contact Manager (PIM) application 9. A Test System for XWiki applications Other nice stuff I've found interesting 1. MindMap Visualization of an XWiki site/set of pages (we have part of it that has been done for a client) 2. Implement WebDAV with XWiki Basically the project 3. Wiki Syntax <-> XWiki Object Mapping 4. Easy Web Services Integration 5. Local Names implementation We had some duplicates projects. Multiple people have proposed to implement the Independent Query API and it would be great to have these people as contributors for the low-level part of XWiki. Let me know what you think and which applicaitons are the most valuable ? Are there any other applications we should provide bounties for ? I've setup a page on XWiki.org if you want to propose additional projects http://www.xwiki.org/xwiki/bin/view/Dev/SummerOfCodeStatus Ludovic -- Ludovic Dubost XPertNet: http://www.xpertnet.fr/ Blog: http://www.ludovic.org/blog/ XWiki: http://www.xwiki.com Skype: ldubost AIM: nvludo Yahoo: ludovic

Re: Google Summer Coding - P2P XWiki

by Bikash Agarwalla

I have submitted a proposal for P2P XWiki to Google and am exploring the current code base so that I get a head-start incase the proposal gets accepted. I have A) Downloaded XWiki source version 0.9.793 B) Looked at developer documentation from http://www.xwiki.org/xwiki/bin/view/Doc/WebHome By looking at overall architecture of XWiki, I think that an offline XWiki will have a different type of Store (centralized store) and a P2P XWiki will have another store implementation (P2P Store). At first glance, it appears that the centralized and P2P store will extend the interfaces XWikiStoreInterface. The interaction with these stores *may* introduce new APIs or use existing XML-RPC API without any changes. I am working on understanding the overall architecture of the current XWiki and identifying how a P2P XWiki can make the best use of existing implementation. I have the following questions: a) I have downloaded the source code but don't see any documentation on how I can run the XWiki completely local to my machine. What are the requirements and steps for running a local wiki from the source code? b) To be sure, am I starting with the correct code base or is there any other version of offline XWiki (may be not fully developed)? Any other suggestions also welcome, Thanks, Bikash Agarwalla

Using container managed datasource instead of hibernate ?

by Erwan Arzur

Hello, Today, while installing xwiki on my own box, i've found very tedious having to edit a file in a tomcat working directory (webapps/xwiki, for instance) to change the database parameters. Having a datasource defined in the container will allow admins to avoid having to learn the internals of the application, and this is how it's done in other apps like jira or confluence. For tomcat, I feel it would be better to : - make sure hibernate.cfg.xml refers to a datasource named "jdbc/XWikiDS" - define the said DataSource in $CATALINA_HOME/Catalina/localhost/xwiki.xml - put the jdbc driver in $CATALINA_HOME/common/lib, now that the container is responsible for opening the connection I think it will also ease the packaging of a standalone xwiki server. What do you think ? I'm attaching the configuration that worked for me almost out of the box. Erwan

Documentation efforts for 1.0 release

by Stephen Schaub

Are there any plans to develop improved documentation for the 1.0 release? In the initial wiki installation, it would be nice if there were a nice "Getting Started" guide for users that explains how to do basic wiki administration, etc. One way to develop this might be to create a virtual wiki at something like home.xwiki.org where current Xwiki users could contribute to developing the initial home page that appears in a default installation. Thoughts? Stephen

Re: Can somebody go over MySQL Connector/J (mysql-connector-java)?

by Ludovic Dubost

Hi Steven, You might want to open a bug in the bug tracker (http://jira.xwiki.org) and detail exactly what you did to try to make it work with MySQL 4.1. I have a test setup where it is running fine on Windows and another one where it's working fine with MySQL 4.1.10a in Debian. We are running with tomcat 5.0.28 and the following mysql driver in common/lib: mysql-connector-java-3.1.8-bin.jar Ludovic Steven C.

[M2] versions of libs?

by Vincent Massol

Hi, I'm working on the Maven2 build and I'm currently adding the dependencies and ensuring they are present on ibiblio and pushing them if they're not, etc. There are several libs in trunk/libs that do not have version attached to the jar name. Could someone in the know rename them with version information or tell me the version so that I can rename them and add them as POM dependency? Also, are you sure there is a Servlet API 2.4? The most recent version I have found is servletapi-2.4-public_draft.jar (or servletapi-2.4-20040521.jar). See http://ibiblio.org/maven2/servletapi/servletapi/. I don't think the 2.4 API has been released yet. Let me know if this is correct or not. Thanks a lot -Vincent
