Content based routing based on message property

[ashok_1979]

Hi All,
i have a situation where i wanted to use cbr.
I have three services
1. SendDataService
2. FTPService
3. SMTPService

SendDataService extracts data and transforms it in client specific format and after transformation it has to route the message to FTPService/SMTPService, the decision maker is the message property "CommunicationMode".
If CommunicationMode is FTP then message should be routed to FTPService and if CommunicationMode is SMTP then message should be routed to SMTPService.

So can any one provide me a sample drools rule which checks for message property?

Thanks in advance...

Hi,

something like this should work:

#list any import classes here.
import org.jboss.soa.esb.message.Message;
import org.jboss.soa.esb.message.Properties;

#declare any global variables here
global java.util.List destinations;

rule "FTPService Rule"
 when
 m : Message ()
 props : Properties() from m.getProperties()
 eval(props.getProperty("CommunicationMode").equals("FTP"))

 then
 destinations.add("FTPService");
end

regards,

/Daniel

Thanks a ton beve,
It worked :-)
This is my final code

#created on: Oct 30, 2006
package com.jboss.soa.esb.routing.cbr

#list any import classes here.
import org.jboss.soa.esb.message.Message;
import org.jboss.soa.esb.message.Properties;

#declare any global variables here
global java.util.List destinations;

rule "FTPService Rule"
 when
 m : Message()
 props : Properties() from m.getProperties()
 eval(props.getProperty("CommunicationMode").equals("FTP"))
 then
 System.out.println("#########Inside FTPService Rule#########");
 destinations.add("FTP-destination");
end

rule "SMTPService Rule"
 when
 m : Message()
 props : Properties() from m.getProperties()
 eval(props.getProperty("CommunicationMode").equals("SMTP"))
 then
 System.out.println("#######Inside SMTPService Rule#########");
 destinations.add("SMTP-destination");
end

I have one question
"Where can i found some good documents to understand the syntax of Drools?"
i had searched on web but couldn't find any good document.

This can be found in the Drools user guide : http://www.jboss.org/drools/documentation.html
