my service is accepting one file with some body contents.while i am uploading through the API manger some how my body is missing.so the body reading function throwing null pointer exception – Jamsheer
shall i change any configuration to support multipart in API manger or any <tag> to use in API – Jamsheer
Do you get any error stack in APIManger server? check wso2carbon.log file for error logs – Ratha
there is no error in carbon log,It seems some content type issue or file missing issue – Jamsheer

I got the solution,Need to enable Binary Relay builders in axis2.xml file to use the multipart/form-data message formatting and also ensure that there is no custom header with request to handle multipart data.

 <messageBuilder contentType="multipart/form-data"
                class="org.wso2.carbon.relay.BinaryRelayBuilder"/>

  <messageFormatter contentType="multipart/form-data"
                class="org.wso2.carbon.relay.ExpandingMessageFormatter"/>
