[opencms-dev] Installation problem (urgent)

[Aurélie PREVIT]

Hello,

I have many problems with OpenCms on Wenlogic Server and Oracle.

When I try to import a module (my own or news module), there is many errors (cmsDbAcces)

For example I find repertories in "systems/module" well but they are empty. 
In logs, it is written :

[21.08.2003 16:18:34] <opencms_info> [CmsRegistry] Saved the registry
[21.08.2003 16:18:37] <opencms_info> [com.opencms.file.CmsObject.publishProject()/2] Project:47 Time:Thu Aug 21 16:18:37 CEST 2003
[21.08.2003 16:18:37] <opencms_info> [com.opencms.file.CmsObject.publishProject()/2] User: [User]:Admin , Id=2 , flags=0 , type=0 :?oâ a
dmin-user
[21.08.2003 16:18:37] <opencms_info> [com.opencms.file.CmsObject.publishProject()/2] Vector was null or empty

So if you have an idea ??

If you can't help me, I want to try to overwrite to OpenCms. I want to know :

Which tables it erases during the setup exactly ?
If it's necessary to drop tables ?
If there is a way to avoid that ?

What I must make exactly to reinstall Opencms ? 
just delete tables opencms from database, delete opencms from "webapps" and reinstall "opencms.war" ?

Thanks you very much 
Bests regards,

Aurélie
