Dear RapidMiner users,

I am trying to read data from a oracle database. However, when I run the procedure, the following error is showed:

Exception: java.lang.NoClassDefFoundError
Message: Could not initialize class oracle.jdbc.driver.DMSFactory

    Hi,
    first of all make sure you downloaded the latest version of RapidMiner x64 from source forge and then got to the Manage Database Drivers menu. See if you have added all *.jar files of the jdbc driver in a comma seperated list to the jar file entry and entered all other parameters of the database driver and connection settings correctly, this should work.

    Greetings,
      Sebastian
