[xwiki-users] Generating pure JSON
by Bryn Jeffries 06 Apr '15

06 Apr '15

I'd like to be able to generate pure JSON from a wiki page, to use in other pages via AJAX. To that end I created a page with the following content: {{velocity wiki="false"}} $response.setContentType('application/json') { "greeting" : "Hello", "location": "World" } {{/velocity}} Calling this via /xwiki/bin/get/Sandbox/JsonTest I get the following code: <p><br/>{<br/>"greeting" : "Hello",<br/>"location": "World"<br/>}</p> I get the same via /xwiki/bin/view/AlertDB/JsonTest?xpage=plain. If I remove the $response.setContentType('application/json') https://dev.alertnessdb.net/xwiki/bin/view/AlertDB/JsonTest?xpage=plain

[xwiki-users] Is there an escape tool to escape text in XWiki syntax?
by Thanh Hong Dai 06 Apr '15

06 Apr '15

Currently, I'm using something like this to generate a list of pages whose prefix is "Prefix:" and link to them: {velocity}} ((( #foreach ($row in $services.query.hql("select doc.name, doc.fullName from XWikiDocument doc where doc.space.hidden = false and doc.space not in ('XWiki', 'Sandbox', 'Main', 'Macros') and doc.name like 'Prefix:%'").execute()) * **[[$row[0].replaceFirst("Prefix: *", "").replaceAll("~", "~~~~").replaceAll("[\x20-\x7f&&[^a-zA-Z0-9 ~]]", "~~$0")>>doc:$row[1].replaceAll("~", "~~").replaceAll("[\x5b\x5d|]", "\\$0 <file:///\\$0> ")]]** #end ))) {{/velocity}} I have tested with some heavy test cases like Prefix: ~~~!!!```@@@$$$%%%^^^&&&***((()))___----+++==={{{}}}[[[]]]\\\|||:::;;;'''""" ???///...>>>,,,<<< And what I have above works correctly (both showing the title and linking to the document). I only work on a few hard test cases, though, so I'm not sure if I missed anything. Is there a method that does all this automatically? Or is there a better approach to this?

[xwiki-users] XWiki utility for stripping HTML
by Bryn Jeffries 06 Apr '15

06 Apr '15

I have a Groovy script that takes input from a form textarea. I'd like to prevent html (and JS) markup from being submitted and, if HTML is submitted, strip it out. Is there a tool already packaged within XWiki to do this, or should I look to an external package like Jericho? Thanks, Bryn

[xwiki-users] Questions about myxwiki
by Kévin Laîné 02 Mar '15

02 Mar '15

Hi everybody, my name is Kévin Laîné, i'm a french guy. I'm working on a collective project about "alternative models of family". Xwiki seems to be the best community tool management I've discovered. I'm really interested for opening an xwiki on the "XWiki Community farm". I have some questions before asking you to open a session. 1) Is it possible to use a domain name like "domain.tld" instead of "domain.myxwiki.org" ? 2) Is it possible to install some extensions as bulletin board or others ? 3) Is it possible to embed "Nabble Free Forums" or other Nabble apps ? 4) Is it possible to make private backup of the xwiki ? Vincent Massol is working on "Alternate URL Scheme" http://dev.xwiki.org/xwiki/bin/view/Design/AlternateURLScheme 5) When it will be ready could I use this option on myxwiki even if I my xwiki is in production ? Thank you very much for your answers.

[xwiki-users] Futex errors
by Aaron Hardy at AC 20 Feb '15

20 Feb '15

Trying to track down the source of some persistent performance issues under load with 6.2 RC 1 (haven't had time to upgrade to 6.2 final yet). I'm maxing out at about 30 or so users before dying on a system with 4GB of RAM. The java interpreter is getting pegged to 100% of the CPU, and about 70% of the calls in the stack trace are futex lock errors. A good chunk of the remainder are gettimeofday calls. Potentially useful info (sorry for formatting): % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 72.75 5361.592109 45075 118947 14045 futex 12.28 905.064191 466 1943354 gettimeofday 4.83 356.110745 3709487 96 45 restart_syscall 2.88 212.173358 836 253729 clock_gettime 2.71 199.867690 8802 22706 recvfrom 2.10 154.843342 37841 4092 poll 1.14 84.282371 580 145307 130153 stat Any ideas? thanks, aaron

[xwiki-users] Failed to execute the [groovy] macro while creating an app within a minute
by Peter Duever 20 Feb '15

20 Feb '15

Hello XWiki Community, while creating an App within a Minute I get groovy executing failures for each element of the form. It is possible to save and finish the process but I cannot access the editor for the content field. That means I cannot enter default entries. You can see the full failure message at the end of the mail. I googled the problem and found entries for Confluence. Maybe they can guide a way: Now I added the "-XX:ReservedCodeCacheSize=64m" option into JAVA_OPTS. (https://bobswift.atlassian.net/browse/SCRP-129) and It worked for me, I just added XX:ReservedCodeCacheSize to my setenv.sh and until now everything is ok. (https://answers.atlassian.com/questions/13535/problem-with-the-script-runne…) I am running version 5.4.5 Thank you for your time! Best regards, Peter Here is the error which is displayed when I reenter the wizard page for step 2: Failed to execute the [groovy] macro: java.lang.VerifyError: (class:

[xwiki-users] Glossary feature of xwiki
by Dai Bo 18 Feb '15

18 Feb '15

Hi, As I have failed to find the related information of this subject, I hope the email group can help me. Why Glossary feature was not implemented in xwiki? Is there any extension or alternatives? I did think Glossary is a useful feature especially for a dev team. Thanks Regards Peter

[xwiki-users] What would you like to see in the XWiki 7.x cycle?
by vincent＠massol.net 18 Feb '15

18 Feb '15

Dear XWiki users, We’re getting close to the end of the XWiki 6.x cycle (6.4 is planned for the end of December) and in January we’ll start developing the XWiki 7.x cycle (which will last the whole 2015 year), starting with XWiki 7.0. Thus it’s time for the XWiki devs to start defining the global roadmap for XWiki 7.x. As XWiki users, I’d like to know if you have some needs for XWiki 7.x. What would you be interested in seeing in XWiki 7.x? I’d like to start some proposal on the xwiki devs list (for the XWiki 7.x cycle) around end of December so it would be nice if you could shoot your suggestion ideas fast so that we can take them into account in the discussion! :) Thanks a lot for your help and I hope you’re enjoying using XWiki! -Vincent Massol XWiki Committer

Re: [xwiki-users] XWiki search/Solr support for additional filetypes
by Arnold, Garth 18 Feb '15

18 Feb '15

Hello Marius - thank you for the detailed reply. My goal is (2) - to find all documents with a .7z attachment, where those attachments include file(s) containing "foo". If I read your email correctly, Tika 1.6 (5) is root cause for my failure to search successfully for text within the files contained in a .7z attachment. I am successful with my search when using a .zip file as the attachment - so we will instruct wiki users to avoid .7z attachments.

[xwiki-users] whiteboard
by Paul Pinkerton (ACLCO) 18 Feb '15

18 Feb '15

Does anyone have experience deploying a whiteboard within a wiki page similar to https://awwapp.com/ , http://webwhiteboard.com/#/ , http://cosketch.com/ or similar? I have a need to deploy one - and using a third party service and embedding it in the page is fine, but am having trouble displaying it. This one with the code pasted below seems to work, but the app/ third party service isn't what we really want - it's a mind map service. Others seem to embed, but then don't display anything. This one seems to be one that could be hosted on our own server (??) which would actually be ideal longterm. https://code.google.com/p/online-whiteboard/ Ideally, I'd like to be able to use one that doesn't require further fees - as it sort of defeats the purpose of our own wiki structure. Anyway, any ideas or your experience here would be appreciated! We are currently running XWIKI ENTERPRISE 5.4.5, but looking at upgrading to 6.3 shortly. {{html clean="false"}} <iframe src="https://www.mindmup.com/#m:a18712bed014d6013247a842795da66744" width="800" height="600" frameBorder="0" webkitAllowFullScreen mozAllowFullscreen allowfullscreen></iframe> {{/html}} Paul Pinkerton ACLCO/ KnowledgeNow Project
