Post method doesn't trigger create entity

Hi,

We are trying to post parameters from Java calling Odata service. First we call get method to get X-CSRF token and then call post method. But, while calling both the methods it triggers get entity set only. During post it doesn't come to create entity. We got the status code 415 as response. Data passed from java is in Application/Json format. Please let me know if the format need to be changed in Java or any property changes required in SAP.

Please guide.

Thanks,

Vikram
