"Error while running RapidMiner through command line in Ubuntu"

Hi All,

I am trying to run RM through command line in linux using the following command:

rapidminer //LocalRepository/ProcessName

I have a Read Database operator which collects data from the local database. However, while running the process through command line
it gives me the following error.

SEVERE: Process failed: operator cannot be executed (Cannot clone com.rapidminer.example.set.SimpleExampleSet: java.lang.reflect.InvocationTargetException. Target: java.lang.NoSuchMethodError: com.rapidminer.operator.Annotations.clone()Lcom/rapidminer/operator/Annotations;. Cause: java.lang.NoSuchMethodError: com.rapidminer.operator.Annotations.clone()Lcom/rapidminer/operator/Annotations;.). Check the log messages...

SEVERE: Here:           Process[1] (Process)
          subprocess 'Main Process'
            +- Read Database[1] (Read Database)
      ==>   +- Generate Attributes[1] (Generate Attributes)
            +- Select Attributes[0] (Select Attributes)

I ran this process using the GUI and it work perfectly.
I think there is something I am missing while running the command line interface but I am unable to figure it out.
I have set the PATH, RAPIDMINER_HOME and MAX_JAVA_MEMORY variables as described in http://rapid-i.com/rapidforum/index.php?topic=13.0

Suggestions are welcome  

Thank you,
Mandar
