Callback URL is not working in Sample Billing Engine WSo2 AM

问题

I tried integrating sample Billing Engine in WSO2 API Manager. Everything was working fine till Subscription. Redirection to store after signup is not working. I am following the steps from below URL. Please guide me.

By default, impl jasr was pointing to 5.0.4 snapshot. Since it's not available i am referring to 6.0.3.

Also, I have installed wso2 in ubuntu and given the jkspath as carbon_home/sercurity/wso2carbon.jks. Is it something wrong?
