not able to get response from deployed package

HI all,

 

I had created a plsql package and uploaded it to integrated SOA gateway. I generated WSDL and deployed the service. But when i am testing the service by calling it using soap ui , the response  coming back is empty as given below.

 

---

<soapenv:Envelope         xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body/>
</soapenv:Envelope>

 

---

Now i tried calling the procedure in the package from another block and found that the data is coming properly there.

But when I searched in SOA monitor and found that the status of the request received is "success" and the response is empty.
