AOP on Remote Proxies

[Srinivaas D]

Hello All,

I am trying to use AOP for my current assignment by following the quick start expamples from the coldpsring site. I am trying to intercept method calls made to remote proxies via webservices from Flex. However the method calls seems not be intercepted. I am not getting any error I am getting the result back whatever the undelying method should return. This is how a part of my coldpsring config file looks. I am not sure whether I am missing anything here.  Any pointers are deeply appreciated.

<bean id="ABCService" class="com.model.pos.ABCService" parent="abstractService">

The Test File Code.

<cfscript>

ABCWS = createObject("webservice",http://infospherix.dev/webservices/com/webservices/ABCWebServices.cfc?wsdl);

response = ABCWS.getTransactions(argumentsinXMLFormat);

</cfscript>

<cfdump var="#Request#" />

 

Thanks,

Well if CS is generating the ABCWebServices CFC and you can invoke methods on it, it sounds like CS is setting things up correctly. If it wasn't creating ABCWebServices.cfc you'd get an error immediately. So my guess is that your interceptor isn't working as you expect. I would try adding some logging calls to your interceptor and the underlying ABCService to write to the log file to see if you can trace what is going on.

Thanks Brian. I will certainly do that. Howver I found out that using cs.getBean("ABC_Remote") in my test file to get the remote object instead of doing webservices invocation the method calls seems to get intercepted.

Hi Brian,

 

After logging the requests  every stage of interception found out that the request was indeed getting logged. But for some strange reason this particular line in my interceptor file is not doing its job as intended " <cfset request.logData = local.logData />".  I am not sure whether we can log anything in Request scope in a webservices call. My original thinking was we can write into request scope for a webservices call.

 

Thanks for all the help.
