Hello,
I am having this same problem as well with RM 5.0. I am trying to connect to an Oracle database and the database driver cannot be located by the application. I have moved the ojdbc14.jar file into the lib/jdbc folder of RapidMiner 5 and restarted RapidMiner a dozen times and the driver never shows up as being available within the "Tools -> Show Database Drivers" window. Any suggestions?
Thanks,
David

Hi,
I wasn't aware that oracle needs some extra effort. Sorry about this, but one simply cannot keep track of everything that's going on in such a huge programming project. As I have been told, we have wiki page with instructions how to add these drivers. It can be found on http://rapid-i.com/wiki/index.php?title=JDBC_Drivers

Thank you for the quick reply , Sebastian! Unfortunately, I am still having difficulty getting the driver to be recognized. I referred to the wiki page you referenced and the instructions listed there were different than what are listed in the "jdbc_properties.xml" file in the /resources/com/rapidminer/resources directory. (There were only two instances of the the xml file in the RapidMiner folder and the wiki said not to use the one in /etc, so I am assuming this is the one I need to modify.)
I added the following line to the xml file under "<driver name="Oracle" and placed the Oracle jdbc driver in C: (I would like to put it with the rest of the drivers in the RapidMiner folder but don't know what the path should be in the xml file).
driver_jar="C:/ojdbc14.jar"
The driver was still not being recognized when I restarted RapidMiner. I then copied the entire jdbc_properties.xml file and placed it in .Rapidiner5 directory of my home diectory and restarted RapidMiner(like the xml file says). When I did this, I was not even able to "Show Database Drivers" within RapidMiner ... the window never appeared.
Obviously, I know I am doing something wrong, but if you could provide me explicit instructions as to how to recognize the JDBC driver, I would really appreciate it. Thanks again for your assistance and keep up the wonderful work!

Thanks again for your help, Sebastian! I was able to get it working this time. I did want to give you a brief rundown on what my experience was to get this working.
1. By default, there was not a "jdbc_properties.xml" file in my home/.RapidMiner5 directory, so I copied the entire file that was in /resources to that home directory as the wiki suggested. I modified the file to add the path to the jar file for the Oracle driver.
2. When I loaded RapidMiner and chose to "Show Database Drivers", I saw duplicate listing for every single driver, but the Oracle driver was showing green.
3. I closed RapidMiner and deleted all the default drivers from the xml file in the home directory leaving only the listing for the Oracle driver.
4. I restarted RapidMiner and there were the appropriate number of listings for each driver.
Thanks for the quick response and for all the assistance!

the jdbc drivers have to be copied to the lib/jdbc directory. To which database are you trying to connect?
