Re: Problem while invoking rule by using drools component
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?

Re: Problem while invoking rule by using drools component
Posted by Arif Mohd <ar...@wipro.com>.
When i tried to give my rule as
rule "Route to tap1"
when
me : Exchange( status == Exchange.ACTIVE, in : in != null )
eval( in.getProperty("org.apache.servicemix.senderEndpoint")=="cbr1" )
then
jbi.route( "service:http://xxx.com/bescocr_031807/tap1" );
end
I got this exception
ERROR - JmsComponent - Error processing exchange InOnly[
id: ID:yyyy
status: Error
role: consumer
service: {http://xxx.com/bescocr_031807}JmsToPipeTapSvc
endpoint: tap
in: <My Message>
error: java.lang.Exception: No rules have handled the exchange. Check your
rule base.
]
I hope the getProperty() function is returning null
My component configuration is as follows
JMS queue(Consumer: service name:JmsToPipeTapSvc)-->eip:Content Based
Router(service name:cbr1)-->SA(DroolsComponent)

Re: Problem while invoking rule by using drools component
Posted by Arif Mohd <ar...@wipro.com>.
Hi Gert,
i have given my condition as follows and working fine
eval(
((String)me.getProperty("org.apache.servicemix.senderEndpoint")).equals("{http://xxx.com/bescocr_031807}cbr1:endpoint")
)
Iam typecasting the Object returned by getProperty method to String, i hope
it will always return String object, can you please confirm that it will not
give class cast exception

Re: Problem while invoking rule by using drools component
Posted by Gert Vanthienen <ge...@skynet.be>.

me.getProperty(...) in your drools file?

Re: Problem while invoking rule by using drools component
Posted by Arif Mohd <ar...@wipro.com>.
No, still iam getting the same exception
Now my rule is like this
rule "Route to tap1"
when
me : Exchange( status == Exchange.ACTIVE, in : in != null )
eval( in.xpath("$org.apache.servicemix.senderEndpoint='cbr1'") )
then
jbi.route( "service:http://intel.com/bescocr_031807/tap1" );
end
i tried to give
in.getProperty("org.apache.servicemix.senderEndpoint")='cbr1'
but even this doesn't work

Re: Problem while invoking rule by using drools component
Posted by Gert Vanthienen <ge...@skynet.be>.

the curly braces) should work fine...

Re: Problem while invoking rule by using drools component
Posted by Arif Mohd <ar...@wipro.com>.
Hi gert,
i have given like this
rule "Route to tap1"
when
me : Exchange( status == Exchange.ACTIVE, in : in != null )
eval( in.xpath("${org.apache.servicemix.senderEndpoint}='cbr1'") )
then
jbi.route(
"service:http://xxx.com/bescocr_031807/tap1" );
end
But iam getting the following exception
As of my understanding this xpath expression will be evaluated over the
message content, but in message content where we will have
"org.apache.servicemix.senderEndpoint" iam bit confused please help me out
in this regard.
ERROR - DroolsComponent - Error processing exchange InOnly[

Re: Problem while invoking rule by using drools component
Posted by Gert Vanthienen <ge...@skynet.be>.
Arif Mohd,
Doesn't the same syntax also works with servicemix-drools? Something like
eval( in.xpath("$org.apache.servicemix.senderEndpoint ...") )
The most convenient way to create your own Auditor by extending
ServiceMix's AbstractAuditor. Secondly, you have to register your
auditor in the <sm:services/> section in conf/servicemix.xml. From that
moment on, every message exchange that flows through the ESB, will
trigger your Auditor's exchangeSent() method, so this allows you to do
logging, archiving, ...

Re: Problem while invoking rule by using drools component
Posted by Arif Mohd <ar...@wipro.com>.
Hi Gert,
Firstly i want to know the sender endpoint from drools component(i.e, i
want to know how to write a rule for determining sender endpoint)
Secondly you are talking about message auditor, could you please elobarate
how to do this? if possible with example.

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...)
