and i also tried
curl https://127.0.0.1:8243/services/stripe/customers -u ******************: -d "description=Customer for example@gmail.com" -d "card[number]=4242424242424242" -d "card[exp_month]=6" -d "card[exp_year]=2013" --insecure -H "Content-Type : application/json"

I am not able to understand what is causing dis problem....
Solution
Define the following property at your outsequence and check..
<property name="messageType" scope="axis2" value="application/json"/>
