Trac show error message in timeline after configured with Hudson Plugin

[ericqiu]

Error message:

Hudson Builds event provider (HudsonTracPlugin) failed:
IOError: Error getting build info from 'http://192.168.16.38:8080/hudson/api/xml?xpath=/*/job/build[timestamp>=1280764799000][timestamp<=1283443199000]&depth=2&exclude=//action|//artifact|//changeSet|//culprit&wrapper=builds': HTTPError: HTTP Error 500: Internal Server Error. This most likely means you configured a wrong job_url, username, or password.

The trac ini I configured for Hudson plugin is as following and no user setup for hudson:

[hudson]
alternate_success_icon = true
job_url = http://192.168.16.38:8080/hudson/
main_page = /hudson/
username =
password =

Also i try to access hudson/api/xml,the content is as attachment

I'm not sure what's wrong, but it's sounding like a Hudson bug. Can you manually try that full URL in the original error message (i.e. including the long query string)? Also, can you check Hudson's logs?

As for hudson, i just simple run it without any user setup and in trac, just put in the plugin then the error come out...no more configuration has been done

I deployed it on tomcat and the log is as following, it seems some problems of trac when I attached the log file, so i put them here:

Yup, it's a Hudson bug - see ​http://issues.hudson-ci.org/browse/HUDSON-7299 . Try the latest (1.375) or an older version of Hudson.
