How to call Wso2bps using wso2esb - wsdl

Question

I am using wso2esb4.8.0 and wso2bps3.0.1 while i am working with 2 servers both are working fine .But i wish incorporate both severs for that i written sample BPEL
sample BPLE file is like this
<bpel:process name="multiply2integers"
targetNamespace="http://wso2.org/bps/sample"
suppressJoinFailure="yes"
xmlns:tns="http://wso2.org/bps/sample"
xmlns:bpel="http://docs.oasis-open.org/wsbpel/2.0/process/executable"
>

-->
<bpel:receive name="start" partnerLink="client"

operation="process" variable="input"
createInstance="yes"/>
<!-- Generate reply to synchronous request -->
<bpel:assign validate="no" name="Assign">
<bpel:copy>
<bpel:from>
<bpel:literal>
<tns:multiply2integersResponse xmlns:tns="http://wso2.org/bps/sample" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><tns:mul>0</tns:mul>
</tns:multiply2integersResponse>
</bpel:literal>
</bpel:from>
<bpel:to variable="output" part="payload"></bpel:to>

</bpel:from>
<bpel:to part="payload" variable="output">
<bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"><![CDATA[tns:mul]]></bpel:query>
</bpel:to>
</bpel:copy>
</bpel:assign>
<bpel:reply name="end"
partnerLink="client"
portType="tns:multiply2integers"
operation="process"
variable="output"
/>
</bpel:sequence>
</bpel:process>
even i am publishing my bpel wsdl also
if i try with wso2bps TRYIT tool its working fine but while calling with wso2esb is not working
WSDL file is
<?xml version="1.0"?>

and i written sample proxy which will call the BPEL endpoint that sample proxy define below

defined endpoint view is my endpoint is

i am sending request from CURL command to ESB I am getting errors my CURL Command is.
curl -v -H "Accept: application/json" -H "Content-Type:application/json" -d '{"c":"55","d":"3"}' http://***t:8282/services/BPELProxy
and its showing errors if i change the format of endpoint its showing some other error error log like this
