Persistent cache of compiled HQL queries?
by THOMAS, BRIAN M (ATTSI) 23 Feb '07

23 Feb '07

In developing my servlet filter, I created some HQL queries against the XWiki object store. These apparently get compiled and cached somewhere in generated code, because when I had an error in a query, changing it and rebuilding the project had no effect on the query text, so that it evokes the same exception and reports the same query text as before, unless I clean my project every time I change the text of the queries. Apparently the dependency of the compiled queries on my class needs to be stated in a way that it isn't currently. Any clues on how to do this? brain[sic]

XWikiPreferences and 0.9.840
by gleeb＠mediaprint.at 23 Feb '07

23 Feb '07

Hi, I migraded a mysql based 0.9.840 XWiki to 1.0B3. I need to keep the old Style/Layout. Unfortunately, I do not get the XWikiPreferences Page. Therefore, I cannot import/export admin pages. Calling http://localhost:8001/xwiki/bin/admin/XWiki/XWikiPreferences leads to a strange Page containing just 'Hello'. After migrating the configuration und preferences pagesare still like in 0.9.840. How can I get the XWikiPreferences page and/or upgrade the admin pages to use the new features? Regards, G Leeb

Questions on setting up virtual servers.
by Duncan Wilson 23 Feb '07

23 Feb '07

Hi, I'm trying to add a second xwiki server to the server I am currently using. I'm running tomcat and using mysql as the database on a linux machine. I know this is going to seem like a huge barrage of questions, but I'm new to this, so please bear with me. First, all the instructions use different subdomains for the different xwiki servers. I know very little about DNS, and was hoping there might be another way. Right now the current xwiki is usually accessed just using localhost in a browser, is there some way I could set up the second instance to use a different address or port or even just a different folder name without having to mess with DNS? Would it be easier to set up my own internal DNS server? Second, I've added the second database to mysql, and granted all privileges to the xwiki user. So now there are two databases, xwiki (the old one) and publicwiki (the new one). What I'm hung up on is creating a new class called "XWikiServerClass". I've created it in the class editor, but I'm not sure what the guide means by "add a string property" for server and owner. From the guide it looks like the plan is, once I get XWikiServerClass set up, to create two pages, Xwiki.XwikiServerXwiki and Xwiki.XwikiServerPublicwiki. I then attach the XWikiServerClass object to each page and set the owner and server fields. Then change the xwiki.virtual entry from 0 to 1 in xwiki.cfg, restart tomcat. Does this sound right? Any and all help is greatly appreciated, Duncan

life time of log-in
by Uwe Kleinschmidt 23 Feb '07

23 Feb '07

Gents, I am using BETA 4 and encountered the following problem: Once logged on there seems to be an inactivity period, which forces a log out w/o warning. The editor for an entry is open, accepts entries but once you want to save what you edited and you took a break of > 10 minutes in between, everything is gone. On the other end with previous betas, I could leave the xwiki for hours go to different URLs, and go back to the Xwiki and I was still logged-on. What are the policies here and IMHO both cases described above should not happen. Thanks Uwe

WIKI editor
by F. Exertier 22 Feb '07

22 Feb '07

Hi all, we are currently deploying xwiki within our company. We use the last stable version, the same as the one used by ObjectWeb (0.9xxx). In this version we are using the WIKI Editor (the wysiwyg one is not running), but we have the following issue: in order to skip a line (to insert some line breaks), it is necessary to insert some "<br\>" HTML statements or some "\\" characters in the content. This is even not documented in the "help frame" on the right of the editor screen. This is a show stopper for us since we cannot ask our end users (people who will provide the content) to know this kind of syntax. Is there any turn around or any patch that could be used to cope with this issue ? We do not want to upgrade to the 1.0 beta version in a short term. Thanks, Best Regards, François

Virtual Wikis and Postgres
by Paul Armstrong 21 Feb '07

21 Feb '07

Has anyone got virtual wikis working on Postgres? I keep getting stack traces when I select save to create XWiki.XWikiServerXwiki_otherwiki when using Beta4, Postgres 8.1.4 and Tomcat 4.0.5. I've tried both with a pre-created database and by giving the xwiki user sufficient privileges to create a database.

use in gwt
by Robert J. Carr 21 Feb '07

21 Feb '07

I'm developing a large-ish web application using the Google Web Toolkit (GWT) and one of the things I'd like to integrate is a wiki. I'd like to use an existing wiki engine and not develop from scratch, and in looking around it seems that xwiki is the best java solution. So, here are my questions: 1) Has anyone integrated xwiki into an existing GWT application? 2) And if not, has anyone integrated xwiki into any other existing java web application? Some guidance on how to approach this would be appreciated (high level is okay, I'll sweat the details), if it is indeed agreed that xwiki is an appropriate solution. Thanks- Robert
