Arif Mohd,

I think this is possible if you use the ${org.apache.servicemix.senderEndpoint} property in your CBR's xpath expressions to determine the sender endpoint. However, if you use the tap's for debugging purposes, I would suggest you build a message auditor that logs the messages somehow (whatever is done by your wiretaps right now). This way, if you do not need the logging, you simply disable the auditor in your ServiceMix configuration. This would also allow you to remove all debugging configuration from your SA, so it only contains real routing/service configuration. This improves the maintainability/readability of your configuration a lot (recently done that for one of my own projects, which also had wiretaps all over...)

Thank you gert,
   1) Iam able to call my rules now without any error.
   2) The example i was using is simply routing a message based on the
content of message, which can be easily done with Content Based Router
   Now i want to do routing based on the source component of the message
from where the message is coming i.e, i want to remove the tap's(used for
debugging) at runtime using drools.

My component setup is

   JMS queue(Consumer)-->eip:Tap1-->eip:Content Based
Router-->eip:Tap2--->eip:Transformer

Now i want to enable/disable Tap1 and Tap2 during runtime by using drools,
for that purpose i planned to have my component setup as follows

   JMS
queue(Consumer)-->SA(DroolsComponent)eip:Tap1-->SA(DroolsComponent)--->eip:Content
Based
Router-->SA(DroolsComponent)--->eip:Tap2--->SA(DroolsComponent)-->eip:Transformer

the logic in rules files should be as follows

if source component is JMS queue, route to Tap1
if source component is Tap1, route to Content based router
if source component is ContentBaseRouter, route to Tap2
if source component is Tap2, route to Transformer


How can i write this kind of rules,please help me in this regard.
Also let me know is it a feasible way of adding/removing components
logically?

Arif,


You can find a description on how to form this kind of URIs on http://incubator.apache.org/servicemix/uris.html.

If you think the URI is correct but still have these 'Cannot find route to ...' errors, you can use a JMX console to verify which endpoints are actually available on the ESB. I think your service URI contained the endpoint name, where it should only hold the service name.

Hi Rabi,

    I didn't understand this concept of giving service name as
"service:http://xxx.com/bescocr_031807/tap1"; but still it is not working

   Can you please elobarate what is the meaning of the above statement, i
agree that previously i have missed to preceede the service name with
namespace i.e, i should have given like

jbi.route( "service:bescocr:tap1" );

But even the above statement is not working

in your routing.drl replace

Subject: Problem while invoking rule by using drools component




Hi,
Iam having the following setup

JMS queue(Consumer)-->eip:Content Based
Router-->SA(DroolsComponent)-->eip:TAP1 or eip:TAP2(Based on rule base)

part of xbean.xml for "eip:Content Based Router" is

      <eip:routing-rule>
        <eip:predicate>
          <eip:xpath-predicate xpath="/Record/eid = 100"
namespaceContext="#nsContext" />
        </eip:predicate>
        <eip:target>
          <eip:exchange-target service="bescocr:myDroolsService" />
        </eip:target>
      </eip:routing-rule>

xbean.xml for DroolsComponent(SU) is

<beans xmlns:drools="http://servicemix.apache.org/drools/1.0";
       xmlns:bescocr="http://xxx.com/bescocr_031807";>
<drools:endpoint
     service="bescocr:myDroolsService"
     endpoint="endpoint"
     ruleBaseResource="classpath:routing.drl"/>
</beans>


routing.drl is

package org.apache.servicemix.drools
import org.apache.servicemix.drools.model.Exchange;
global org.apache.servicemix.drools.model.JbiHelper jbi;

rule "Route to tap1"
        when
                me : Exchange( status == Exchange.ACTIVE, in : in !=
null
)
                eval( in.xpath("/Record/eid = 100") )
        then
                jbi.route( "bescocr::tap1" );
end

rule "Route to tap2"
        when
                me : Exchange( status == Exchange.ACTIVE, in : in !=
null
)
                eval( in.xpath("/Record/eid = 101") )
        then
                jbi.route( "bescocr::tap2" );
end


with the above setup iam getting the following exception "for service:
null
and interface: null" the exception is as follows, do i need to set
something
else in xbean.xml?

javax.jbi.messaging.MessagingException: Could not find route for
