Re: [HippoCMS-dev] Duplicate class error while starting hippo cms editor

Hello all,

After stopping editor, emptying logs, and starting editor again, issuereappeared. Now only wrapper.log contained exception stack trace:


2008/05/20 09:27:39 | STATUS | wrapper  | --> Wrapper Started as Daemon
2008/05/20 09:27:39 | STATUS | wrapper  | Launching a JVM...

2008/05/20 09:27:40 | INFO | jvm 1 | Wrapper (Version 3.1.2)http://wrapper.tanukisoftware.org

2008/05/20 09:27:40 | INFO   | jvm 1    |
2008/05/20 09:27:40 | INFO   | jvm 1    | Starting Fortress

2008/05/20 09:27:42 | INFO   | jvm 1    | Fortress started

Regardless of the exception being thrown, everything appeared to workfine. Nevertheless, it's not a nice feeling knowing that upon startuphippo cms editor throws such an exception. Problematic class was onlypresent in sole quartz jar in cms editor installation - quartz-1.5.2.jarAfter searching for same class in Hippo repository installation, it wasfound in quartz-1.4.5.jar. Replacing quartz-1.5.2.jar withquartz-1.4.5.jar in cms editor installation solved the issue, exceptionis no longer being thrown.

Problem now is, that there must have been reason why newer quartz jarwas used in cms editor. Can someone from Hippo confirm that cms editorwill (continue to) work with this older version of quartz jar? Also, asthis is just a workaround which appears to work, maybe someone of Hippoguys can have a closer look what the actual issue is - is there justsome incompatibility between cms editor and this newer quartz jarmanifesting only in this specific configuration (Ubuntu, Postgres /wSlony master-slave configuration, Hippo repository in load balancedconfiguration), or do editor and repos need to use same version ofquartz jar, or something else.

Btw, startup scripts onhttp://www.hippocms.org/display/CMS/Linux+init+scripts are slightly outof date (e.g. Suse example references start.sh and stop.sh but there areno such files in distribution and sources of the editor nor for repos).Anyway, they were useful as starters for creating version for Ubuntu,and attached you can find init scripts and their respectiveconfiguration files for Ubuntu. For them to function well, "links" needsto be installed ("sudo apt-get install links" should do). Being a newbiein shell scripting and linux in general, don't take these scripts tooseriously. I'd appreciate if someone more experienced can take a look atthem. Suse version of scripts used "daemon" to start and stop cmseditor, but I couldn't make editor startup like that.


Regards,
Stevo.

Hello Bartosz,
I agree, wiki is out of date, but it wasn't a problem. There were twoissues actually, and log didn't help at all to find them. First onewas that wrong jdbc driver was used (8.2-507.jdbc4 instead of8.3-603.jdbc4, as database is postgres 8.3). Other issue was thatwrong ip address in master/slave configuration were specified, in aSlony replicated database configuration, load balancer was pointingto slave as it was master, and slave refused insert/updatestatement(s) cms editor tried to issue.
Good to hear you got everything working, and thanks for reporting back.

I've modified the wiki page.

Regards,
