[Oreka-devel] recording metadata is not being saved in the database

Hello!
I am running orkaudio successfully. Recordings are saved correctly in the file system. Metadata for these recordings do not appear in oreka database though.
Environment:
This installation runs on 64-bit CentOS 6.2. 
Orkaudio is built from source as illustrated on http://oreka.sourceforge.net/oreka-documentation.html#building-oreka. For orktrack and orkweb, I downloaded oreka-1.7-838-orktrack-orkweb.zip package. And then followed install instructions from README.txt inside this package.
Issue:
I can login to http://localhost:8080/orkweb/app successfully. However no recordings are seen here. I am passing past and future date respectively in date filters but nothing shows up.
Investigations:Investigation#1
I checked orkweb.log as well as orkaudio.log. There are a few errors/warnings but I am not sure if they contribute to this issue. Here are their details:

Investigation#2I ensured oreka database user has both read and write permissions to entire database. However all database tables remain empty except for orkuser table which has just one record for admin user.
Investigation#3
Errors 1 and 2 above refer to streamingport# 59120 in the URL however orkaudio.log shows "event streaming server running on port 59150". Could this be the issue? Where to change this port number? orkservice table is also empty in the database.
Investigation#4
I login to tomcat manager interface - it shows both orktrack and orkweb applications are running successfully. I also tried following URL which returns (success=true)http://127.0.0.1:8080//orktrack/command?type=initHowever http://127.0.0.1:8080//orktrack/command?type=init returns (success=false)

Investigation#5
I tried changing TrackerHostname inside /etc/orkaudio/config.xml to localhost as well as 127.0.0.1 - both of them return same behavior (i.e. success=false,  comment:OrkObjectFactory class does not existinit).
Please provide some insights.
Thank you!
