Hello,
i have a problem to use entity-beans (ejb 3.0) in a DRL-file.
If i use java-beans everything works fine, but when I use the following rule
with the "pruefungs"-entity object i get an exception. What is the problem,
can i use EJB 3.0 entitybeans with drools?
My rules are the following:
rule "Test Entity"
when
p : Pruefung( name : pruefungsName )
then
System.out.println( name )
end
rule "Hello World"
when
m : Message( status == Message.HELLO, message : message )
then
System.out.println( message );
m.setMessage( "Goodbye cruel world" );
m.setStatus( Message.GOODBYE );
update( m );
end
and the exception that occurs:

New subject: When to Use Rule Flow File
You do not HAVE to use ruleflow. If you do not want to use it or know why
you would need it, you shouldn't. Ruleflow can be used to define the order
in which your rules / rule sets should be executed, which might become
important if you have a lot of rules. Read more in the docs on how / why to
use ruleflow.

That has nothing to do with the type of Object.
There's simply missing the ";" at the end of the RHS line.
