[rules-users] Jbilling Drools performance

[Antonio Anderson Souza]

Dear Greg,

Thanks very much for your reply.

I'm using sequential mode = true

Is there a way to create this PhoneNumber class, and convert the String to
the PhoneNumber object inside the Drools? Because I'm using a system called
JBilling and it send the phoneNumber as a String.

Sorry if those are basic questions, but I'm a newbie in Drools...

Thank you very much,
