I have a play! application with typesafe activator which works well on the original developer's computer. But when I try to run the app on my computer with the command " sudo ./activator run ", I get the following error.

The com.samza.adapter.JobFactory class does exist and is in the correct directory.
The 29th to 32st lines of API.scala is:
def start: Unit = config getStringList ("task-containers") map
{
load(_) run
}
Then I tried to define the class path with command
export CLASSPATH=${CLASSPATH}:/directoryTo/com/samza/adapter
But unfortunately it didn't work..
