Hi
How can I create my own macro in my xwiki (say, a macro for adding two numbers). Where should I write it. So that I can use it from any page ?

Hi
How can I adjust the logon time out?
Users disconnect of the xwiki after 30 mn...
I want higher this time for all users.

Hi,
I installed xwiki and there are no users installed and no option to create new users. The user's page is empty. The only way I found to work was to allow the superuser account but there is no other user and now way to add users.
Any ideas?

Hi all,
What is the delete access right supposed to do? It doesn't seem to do
anything currently, at least in 1.0. In the albatross skin, if I enable
delete rights in a space for a non-admin, the delete button does not
appear for that user. Thanks ...

I am trying to run xwiki with Ingres, for this I have converted file
xwiki-db-0.9.2.sql to ingres compatible format. And I ran this file on
Ingres database. I have everything else in place: drivers, configuration in
hibernate.cfg.xml etc...
My app server is JBoss 4.0.5, so when I start xwiki I get:
17:54:49,830 FATAL [DBCPConnectionProvider] Could not create a DBCP pool

so i removed connection.provider_class property from hibernate.cfg.xml.
Afterwards when i tried running xwiki i got this exception and xwiki page is
not coming:
18:11:49,447 ERROR [JDBCExceptionReporter] line 1, Table 'xwikidoc' owned by
'advait.trivedi' does not contain column 'xwd_default_template'.
.......
I noticed that this column is not part of "create table" sql but somehow it
is getting added to the table definition afterwards. Because i noticed this
column using "describe xwikidoc" mysql command. Please help

Hi there,
Working to solve my SecurityExceptions running on a shared hosting, I
tried to create a similar environment on my local Tomcat. The problem is
not solved, but what I got so far may be useful for some XWiki users.
After running "server.bat -security" I started getting errors related to
Log4J already described by other threads on the mailing list archive,
which I solved this way:
1. Take the log4j.properties from WEB-INF/lib/xwiki.jar and put it as
WEB-INF/classes. The Servlet API specs state that WEB-INF/classes comes
in the web app classpath before jar files placed in WEB-INF/lib.
2. Changed so the log file gets an absolute path under the web app context:
log4j.appender.file.File=C:/java/apache-tomcat-5.5.23/webapps/xwiki/xwiki.log
3. The default security config don't let an application write to its own
files, so I had to add to Tomcat calatina.polity
grant codeBase "file:${catalina.home}/webapps/xwiki/-" {
permission java.io.FilePermission
"c:/java/apache-tomcat-5.5.23/webapps/xwiki/-", "read,write,delete";
};
And them when I start XWiki I get the same error I get from my hosting
provider, that is:
javax.servlet.ServletException: Error number 3 in 0: Could not
initialize main XWiki context
Wrapped Exception: access denied (java.io.FilePermission
\WEB-INF\xwiki.cfg read)
Note that you could have used System Properties in the policy file, such as:
grant codeBase "file:${catalina.home}/webapps/xwiki/-" {
permission java.io.FilePermission
"${catalina.home}/webapps/xwiki/-", "read,write,delete";
};
And you could have specified a file path completely outside the context
tree, which would be better from a security standpoint.
Then I though: Why not adding a permission to "/WEB-INF/xwiki.cfg" so
the (buggy) XWiki configuration file access code works as it would
without a Security Manager?
The changes to catalina.policy become:
grant codeBase "file:${catalina.home}/webapps/xwiki/-" {
permission java.io.FilePermission
"${catalina.home}/webapps/xwiki/-", "read,write,delete";
permission java.io.FilePermission "/WEB-INF/xwiki.cfg", "read";
};
And the result is:
javax.servlet.ServletException: Error number 3 in 0: Could not
initialize main XWiki context
Wrapped Exception: Error number 3001 in 3: Cannot load store class
com.xpn.xwiki.store.XWikiHibernateStore
Wrapped Exception: access denied (java.io.FilePermission
\WEB-INF\hibernate.cfg.xml read)
Hey, XWiki reads the Hibernate configuration file the same way it reads
it's own configuration file... I guess it shouldn't, but let's apply the
same workaround:
permission java.io.FilePermission "/WEB-INF/hibernate.cfg.xml",
"read";
And then I get:
com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize
main XWiki context
Wrapped Exception: Error number 3202 in 3: Exception while reading
document XWiki.XWikiPreferences
Wrapped Exception: Could not create a DBCP pool
com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:291)
com.xpn.xwiki.XWiki.getXWiki(XWiki.java:383)
com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:96)
My DBCP Pool config should be ok because the same local XWiki instance
runs fine without a security manager. Probably I need something else
(that is, not a java.io.FilePermission) to reach the local MySQL
database. Hum, who knows using an embebed HSQLDB would be a workaround....
Digging into Tomcat logs, I found:
java.net.SocketException: java.security.AccessControlException: access
denied (java.net.SocketPermission 127.0.0.1:3306 connect,resolve)
at
com.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:151)
at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:280)
at com.mysql.jdbc.Connection.createNewIO(Connection.java:1765)
at com.mysql.jdbc.Connection.<init>(Connection.java:430)
at
com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:268)
Which leads to a new permission:
permission java.net.SocketPermission "127.0.0.1:3306", "connect,
resolve";
And now to a different exception:
com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize
main XWiki context
Wrapped Exception: Error number 3202 in 3: Exception while reading
document XWiki.XWikiPreferences
Wrapped Exception: net.sf.ehcache.CacheException: Cannot configure
CacheManager:
jar:file:/C:/java/apache-tomcat-5.5.23/webapps/xwiki/WEB-INF/lib/xwiki.jar!/ehcache.xml:12:
Could not set attribute "path".
com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:291)
com.xpn.xwiki.XWiki.getXWiki(XWiki.java:383)
com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:96)
Another configuration file to migrate to WEB-INF/classes. Changed it so
ehcache never uses disk:
<ehcache>
<!--
<diskStore path="java.io.tmpdir"/>
-->
<defaultCache
maxElementsInMemory="10000"
eternal="false"
overflowToDisk="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
<!--
diskPersistent="true"
-->
diskPersistent="false"
diskExpiryThreadIntervalSeconds="120"
/>
</ehcache>
And I got stuck to a reflection error inside Struts:
javax.servlet.ServletException: Error number 3 in 0: Could not
initialize main XWiki context
Wrapped Exception: Error number 3202 in 3: Exception while reading
document XWiki.XWikiPreferences
Wrapped Exception: access denied (java.lang.reflect.ReflectPermission
suppressAccessChecks)
org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:535)
Well, I know a number of Struts applications that run in shared hosting
plans. There should be a way out of this.
But as I was already messing with catalina.polocy, I added:
permission java.lang.reflect.ReflectPermission
"suppressAccessChecks";
And now finally XWiki starts fine.
But when trying to create a new page:
com.xpn.xwiki.XWikiException: Error number 3201 in 3: Exception while
saving document Main.Teste do SandBox
Wrapped Exception: Error number 3211 in 3: Exception while updating
archive Main.Teste do SandBox
Wrapped Exception: access denied (java.util.PropertyPermission user.name
read)
And here we go, more messing with catalina.policy:
permission java.util.PropertyPermission "user.name", "read";
No I can create new pages inside the Wiki, and add Comments and files to
the page. Looks like I found all it takes to run XWiki inside a Security
Manager. Here's the final form of my aditions to catalina.policy:
grant codeBase "file:${catalina.home}/webapps/xwiki/-" {
permission java.io.FilePermission
"${catalina.home}/webapps/xwiki/-", "read,write,delete";
permission java.io.FilePermission "/WEB-INF/xwiki.cfg", "read";
permission java.io.FilePermission "/WEB-INF/hibernate.cfg.xml",
"read";
permission java.net.SocketPermission "127.0.0.1:3306", "connect,
resolve";
permission java.lang.reflect.ReflectPermission
"suppressAccessChecks";
permission java.util.PropertyPermission "user.name", "read";
};
And dont' forget changes to lig4j.properties and ehcache.xml which had
to be moved from WEB-INF/lib/xwiki.jar to WEB-INF/classes.
The problem is, I'm almost sure my ISP will refuse to add
[java.lang.reflect.ReflectPermission "suppressAccessChecks"]. Others
should be fine. So I'd be very grateful if someone helps me making
Struts not need this permission.

I already tried to post this question earlier via the ObjectWeb Sympa interface,
but did not see it back in the archive list, nor did I get a e-mail
confirmation. So please excuse me if it is posted twice now.
I am currently evaluating XWiki for deployment in my company. So far everything
looks great, but I ran into a blocking issue. I have setup XWiki to authenticate
with LDAP, which is a requirement for us. The user names provided by our LDAP
server all have dots in them, like 'eric.ter.haar'. XWiki seems to have a
problem with this. When login in for the first time it creates a new user name
that is equal to the part after the last dot, e.g., 'haar'. And it creates a
space with the other part, like 'eric.ter'. The next login fails but without any
notice.
Does anyone know how to get around this?
Thanks,
Eric
hej,
does anyone know whether it is possible to import a snipsnap exported xml ?
as far as i know both are based on the radeox engine and as snipsnap is no
longer maintained, lots of people will have to look for a migration path -
and xwiki looks really promising.

Hi there,
After running XWiki fine in my local server, I'm trying to run it on my hosting provider.
Acces to WebHome yelds the error:
javax.servlet.ServletException: Error number 3 in 0: Could not initialize main XWiki context
Wrapped Exception: access denied (java.io.FilePermission /WEB-INF/xwiki.cfg read)
I tried changing web.xml to
<env-entry>
<env-entry-name>XWikiConfig</env-entry-name>
<!--
<env-entry-value>/WEB-INF/xwiki.cfg</env-entry-value>
-->
<env-entry-value>/virtual/lozano.eti.br/www/xwiki/WEB-INF/xwiki.cfg</env
-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
That is, I tried cofiguring the real phisical path to the xwiki.cfg file,
But still get the same error.
My ISP tells me Xwiki is trying to get /WEB-INF/xwiki.cfg as an absolute file system path,
not as a context-relative path, and it looks like changing the <env-entry> has no effect.
What should I do?
