I am trying to invoke a web service using call mediator. But I do not see any log about the call in the wso2 logs. The goal is to display the data from a file in the web service.
Yes you can, after the Call mediator put a Log mediator.

I have created a API in API manager. I can invoke it with

wso2 configuration process with to send the response is other than 200 response code
reportsendpoint:
<?xml version="1.0" encoding="UTF-8"?>
<endpoint name="reporsendpoint" xmlns="http://ws.apache.org/ns/synapse">
<http method="get" uri-template="http://localhost:6547/generatereports/1.0/Reports/{uri.var.dcuid}/{uri.var.vcid}"/>
</endpoint>
I assume you want to send a mail if the status code is other than 200. Then you can use mailto transport or mail connectors such as gmail connector outlook connector and add the configuration in the default section in the configured switch mediator.
I have custom mediator where we are validating internal authentication system. If authentication fails, mediator return false. Client receiving response as HTTP status code 202. This I want to override with some JSON response like { "authError" : "Authetication failed - TOKEN_INVALID" }. Please let me know how to handle such scenarios.

In your class mediator, you can throw a SynapseException
In this case, inSequence mediation stop and faultSequence will be executed
In the faultSequence, your can use mediator payloadFactory with media-type="json" to build your json message and send it to the client with <send/>
My aim is i have to receive the url's like www.google.com from client in proxy service and send response back to client.
How can i solve this.Here i am sending my proxy service.

Thanks
In the outSequence of a proxy service, when you call <send/> , the response will be sent back to the client. Try sample proxy service [1], and invoke using Try-It or SOAP UI. You will see that the response comming to the client.

My Proxy Service deployed on ESB is calling another standalone REST service. This service returns HTTP status 200 along with some data in the response body. My question is how I can retrieve HTTP status from response. Here is my configuration:
<proxy name="CQProxy"
transports="https http"
startOnLoad="true"
trace="disable">

</proxy>
<sequence name="GetTaskTicket">

<property name="REST_URL_POSTFIX"

<property name="OSLC-Core-Version" value="2.0" scope="transport"/>
<property name="Accept" value="application/rdf+xml" scope="transport"/>
</endpoint>
</send>
</sequence>

I tried the following code:
<log>
<property xmlns:ns="http://org.apache.synapse/xsd" name="Status" expression="get-property('HTTP_SC')"/>
</log>
And this one too:
<log>
<property xmlns:ns="http://org.apache.synapse/xsd" name="Status" expression="get-property('axis2', 'HTTP_SC')"/>
</log>
But all of them returned null.
After reading WSO2 documentation in more details, I found the right answer:
<property xmlns:ns="http://org.apache.synapse/xsd" name="Status" expression="$axis2:HTTP_SC"/>
It is weird that the documented get-property('axis2', 'HTTP_SC') does not work.
Posting the solution that worked for me:
<property scope="default" type="STRING" name="HTTP_STATUS_CODE" expression="get-property('axis2', 'HTTP_SC')"/>
<log level="custom">
<property expression="get-property('HTTP_STATUS_CODE')" name="HTTP status code received: "/>
</log>
I am using WSO2 4.0.3 on Mac OSX 10.6 I have Data Services Server feature enabled(3.2.2
working in wso2esb 4.0.3 on aggregate mediator.
Below is the code, where the iterate mediator worked perfectly, but the aggregate mediator does not seem to get recognized, as the log in it is not getting printed .The response from the endpoint is getting printed in the log level=full of outsequence, but the flow is not getting continued in aggregate.
Could anyone from wso2team please confirm whether aggregate behaves as expected in wso2 esb 4.0.3?

Appreciate a response on this!
Log mediator is only applicable inside "onComplete" tag in Aggregate mediator. So following log will not recognized and it is an expected behavior,
<log level="full" separator=",">
<property name="ValidResponse" value="TEST ---------------- Sending the Response Back."/>
</log>
but the following log which you have added within "onComplete" tag should work,
<log level="full" separator=",">
<property name="ValidResponse" value="TEST 1 ---------------- Sending the Response Back."/>
</log>
