It depends what's your situation. This error generally mean that you don't have xwiki-commons-logging-logback jar in your classpath. On Tue, Mar 13, 2012 at 12:26 AM, Paul Libbrecht <[email protected]> wrote:

Hello XWiki experts,

how do you debug:        org.xwiki.component.manager.ComponentLookupException: Can't find descriptor for the component [role = [org.xwiki.logging.LoggerManager] hint = [default]]

It seems to prevent startup of my XWiki.

thanks in advance

Thank you Thomas,

after a morning of maven fun.... I did get a lot further with my upgrade of curriki's core (from 3.1 to 3.5).

I have to say that this is much of a guess work ("à tâtons" in french): - from missing dependencies, I could infer using nexus search, that they were reformulated to something else - from missing classes, I can easily find a missing jar (with nexus, my own knowledge, or google) - from extra jars (we still had plexus-container alpha-30), I could guess to get rid of them by seeing odd exceptions

I am stuck with the below:

...

2012-03-13 11:54:15,269 [http://hoplahup.homeip.net/xwiki/bin/view/Main/] WARN  onfiguredQueryExecutorProvider - Could not find a QueryExecutor with hint hibernate which is the hint for the storage engine. the default QueryExecutor will not be used instead. org.xwiki.component.manager.ComponentLookupException: Can't find descriptor for the component [role = [org.xwiki.query.QueryExecutor] hint = [hibernate]]       at org.xwiki.component.embed.EmbeddableComponentManager.getComponentInstance(EmbeddableComponentManager.java:335) ~[xwiki-commons-component-default-3.5.jar:na]       at org.xwiki.component.embed.EmbeddableComponentManager.lookup(EmbeddableComponentManager.java:147) ~[xwiki-commons-component-default-3.5.jar:na]

Would be nice to have a bit more of the stack trace to see what is trying to lookup this component. I don't know any QueryExecutor with this hint, there is only "hql" and "xwql" which are the supported query languages. "hibernate" does not make much sense at this level. Probably some code which wrongly use "hibernate" instead of "hql".

a hint here would be cute. I do not know where to search anymore.

One thing that could help is that each release provides a list of "implementors" for each component's contract and hint. I'm sure maven can do that, I think it should be published.

I am not sure how i should know that I should ignore some jars...

You need the full stack trace. Without more data I'd say you're simply missing the XWiki Logging JAR in the webapp classloader. Thanks -Vincent

I suppose that means xwiki-commons-logging-api-3.5.jar and xwiki-commons-logging-logback-3.5.jar. Both are there. Among the helpers, I found that comparing to a working 3.3 was useful (and using help:effective-pom on a checkout). I see no difference (except s/3.3/3.5).

is there any one I should not use?? Thus far I believe I needed the legacy one to compile our modules... I guess this can be changed one day.

The oldcore legacy module wraps the oldcore (ie includes it). You need to use one or the other. Thanks -Vincent
