Hello dear XWikiers,
one of the issues of XWiki which keeps coming up since many many versions are "failed
restarts". They manifest themselves as a web-application that misses something I
could never identify and starts triggering lack of authorizations.
They tend to fairly randomly. Rather more rarely on fast machines. About 5% of the times
on our T2000.
However, since i am in a clustered situation, it happens considerably more frequently,
almost 90%.
How can I debug these?
I see nothing suspicious in the console and the web line manifests itself as follows:
thanks for hints.
Paul

Once again having one such failed restart...
Somehow, this may be related to the programming permission model.
One thing that we call steadily on all pages is
$xwiki.includeTopic('Admin.Configuration', false)
and I think this is the one that fails often.
Can it be this should never be authorized if not having programming right?
(and it was in version 1.5 or so)
thanks for hints. This remains troubling.

Hi Paul,
I have never seen nor heard anything like in XE so IMO this must be coming from the way
curriki uses the XWiki platform.
To debug is "easy". Simply start curriki in debug mode (see
start_xwiki_debug.sh), open your IDE and connect to the running JVM. Then you can trace
execution step by step.
Not sure if it helps much but I cannot think of anything specific.

which IDE do you use? Eclipse with the XWiki Eclipse Plugin?

sounds interesting. Can you use the XWiki Eclipse Plugin for IntelliJ IDEA? Or how did you do it?
Why would I use the XWiki Eclipse plugin? :)

New subject: [xwiki-users] developing XWiki pages with IntelliJ (was: failed restarts)
Moritz,
I edit all my xwiki pages with IntelliJ which gives me velocity syntax and groovy syntax
awareness.
They're stored in files and I upload them with a little script.
Together with a good classpath, you get auto-completion on all objects which you can also
declare in the header with such a syntax as:
#* @vtlvariable name="xwiki" type="com.xpn.xwiki.api.XWiki" *# ##
#* @vtlvariable name="context" type="com.xpn.xwiki.api.Context" *# ##
#* @vtlvariable name="util" type="com.xpn.xwiki.api.Util" *# ##
#* @vtlvariable name="escapetool"
type="org.apache.velocity.tools.generic.EscapeTool" *# ##
Unfortunately, the velocity mode is for the pro version only.
That's very successful with syntax 1, I think it is a bit more picky with syntax 2 but
I have little experience there.

Hi Vincent,
I use a browser to open the page I want.
An IntelliJ plugin similar to XEclipse would be very neat but I haven't found the time
to work on that.
Thanks

I am wondering how you connect to your XWiki – for developing as well as for debugging?

Well,
here's one I had twice in a row and which happens often:

That's completely obtuse to me and is not curriki-related (Curriki was made before the
extension respository).
The numbers vary, the previous one had:
