"rapidminer integration with java and glassfish"

Hi 

i created a process in rapidminer studio 7.4 and then i'm calling that file in a java application. I used that code and it worked but when i use the exactly same code in a EJB Module i'm having this error 

Caused by: java.lang.NoClassDefFoundError: com/rapidminer/license/AlreadyRegisteredException

when it tries to execute this line of code

 RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);

can anybody help me ? 

thank you so much
