[xwiki-users] Using Velocity to generate HTML
by Grüner Heinrich 29 Feb '12

29 Feb '12

Hi, I created a velocity macro and called it like this. {{velocity}} $services.xtestprogress.render() {{/velocity}} It happens that all <link/> -Tags inserted in the render method are removed in the resulting website. Any ideas? Thanks, Stefan.

[xwiki-users] Getting java.io.IOException: Server returned HTTP response code: 403 for URL… But thru browser it works fine?
by mohit gupta 29 Feb '12

29 Feb '12

I have two web application hosted on two different tomcat instances say T1 and T2(xwiki is on T2). I am making below method in a java class on T1 to retrieve java xwikiUserObject named from T2 private Properties checkContentChanges() { Properties reply = null; try { String urlStr = " http://myApp:8080/wiki/bin/view/?checkContent=true&Name=dummy;" URL url; reply = new Properties(); try { url = new URL(urlStr); //sun.net.www.protocol.http.HttpURLConnection conn = (sun.net.www.protocol.http.HttpURLConnection) url .openConnection();//line 1 URLConnection conn = url .openConnection();// line 2 conn.addRequestProperty("User-Agent", "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)"); InputStream is = conn.getInputStream();// line3 reply.load(conn.getInputStream()); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace();//line 5 } } But at line 3 i am getting error java.io.IOException: Server returned HTTP response code: 403 for URL: http://myApp:8080/wiki/... Though the call goes to method on T2 and it returns expected user object. So T2 side works fine but once it return i get above exception at line 5 at T1 . I tried line 1 too instead of line 2 but same exception? As i tried to find it out on net especially on http://en.wikipedia.org/wiki/HTTP_403 looks like its due to some config on xwiki side. Not getting whats the exact issue? Though thru the brower same url works fine .

[xwiki-users] [GSOC] XWiki is applying for GSoC 2012. Proposals and mentors needed
by Eduard Moraru 29 Feb '12

29 Feb '12

Hi devs, XWiki is planning to participate in this year's Google Summer of Code [1]. The organization registration period has already started and the deadline is the 9th of March [2] (a bit more than one week). 1. We need to provide by then a list of proposals and assign mentors for the students that are going to implement them. I would like to ask everybody that wants to participate as a mentor from the XWiki organization to review the proposals [3] list (that is currently empty) and add as many interesting proposals as possible. The proposals can be either new, or they can be revived from previous year proposals. Just navigate to the previous years, find the proposal you like and know about, go to its proposal page (click it) and press the "Clone to this year" link. Now you can assign yourself as lead for that project, update it's description if needed and wait for the student applications to start pouring :) 2. We also need to submit the actual application [4] of the XWiki organization to participate to the GSoC 2012 project so I would also like to ask you to review it so that we have a better chance of being selected into the program. Thanks for your help, Eduard ---------- [1] http://www.google-melange.com/gsoc/homepage/google/gsoc2012 [2] http://www.google-melange.com/gsoc/events/google/gsoc2012 [3] http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/#HProposedProjects28… [4] http://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/OrganizationApplicat…

[xwiki-users] Fwd: Problem migrating to filesystem attachments in 3.3
by Brian Forsythe 28 Feb '12

28 Feb '12

I currently have my attachments stored in the database and am attempting to migrate to filesystem storage. Toggling it seems to work fine for new attachments. My issue is with migrating attachments via the FileSystem Attachment Porter script (http://extensions.xwiki.org/xwiki/bin/view/Extension/Filesystem+Attachment+…) Before running it, I change my config so that I'm back to using database attachments. I've updated the obsolete class references, and also whittled it down to just the doIt() method, but when running it, I receive the exception "Unknown entity: org.xwiki.store.legacy.doc.internal.ListAttachmentArchive" Please advise. Thanks ahead, Brian

[xwiki-users] Blog entries for specific category
by Joris Dirks 28 Feb '12

28 Feb '12

Hi, I'm missing an option to show recent blog entries for a specific category, e.g. in a panel. Is there such a feature available? I can imagine others have needed/used such a feature before. Right now I'm just trying to hack Blog.RecentPostsPanel to filter on category, but I can't wrap my head around the query needed. In 'getEntriesForCategory' (Blog.CategoriesCode), the query is: #set($query = ", DBStringListProperty as categories join categories.list as category${query} and obj.id = categories.id.id and categories.id.name='category' and category in (${parameters})") But that's about 10 degrees too difficult for me to comprehend :) Any hints? Thanks! Joris

[xwiki-users] Loss of WebPreferences params
by CHENEAU-GREHALLE Nicolas 28 Feb '12

28 Feb '12

Hi, Since the migration from XEM 3.2 to XEM 3.4, We have a strange behaviour on our multi-wiki instance: Sometimes, values of WebPreferences disappear spontaneously on one of our sub-wiki. We lose configuration, look & feel and access rights parameters. There is no apparent reason (the parameters are simply re-initialized). Do you know this problem ? Thank you NCG PS : I've previously posted this topic direcly on the forum by mistake. I think It wasn't posted on mailing list. Sorry if this topic is duplicated
