Error activating objectdb

C: \ Users \ Roberto Pinto> java -cp objectdb.jar com.objectdb.Activator
Error: The main class com.objectdb.Activator was not found or loaded

this is the path of the activator D: \ BBDD_Entornos \ Objecdb \ Objectdb-2.74_03 \ objectdb-2.7.4_03 \ bin

this is the route where the clkase Activator package is
please tell me what I'm doing wrong

post data: Thanks for the license and for the support, a very cordial greeting

Java searches for the objectdb.jar file in the current directory and cannot find it.

Either specify the full path of objectdb.jar or run the command after moving into the bin directory.
