i using adaptivepayments api.the code paypal key is,

    payrequest payrequest = new payrequest(requestenvelope, "pay_primary",                 getproperties().getproperty("paypal_failed_url").trim() + bookingid, "sgd", receiverlist,                 getproperties().getproperty("paypal_success_url").trim() + bookingid);         payrequest.setfeespayer("primaryreceiver");         payrequest.settrackingid(transactionkey);         payrequest.setreceiverlist(receiverlist);         adaptivepaymentsservice service = null;         map<string, string> sdkconfig = new hashmap<string, string>();         sdkconfig.put("mode", "sandbox");         sdkconfig.put("acct1.username", "sg_owner_api1.owner.com");         sdkconfig.put("acct1.password", "wy8haw6wgunm3r72");         sdkconfig.put("acct1.signature", "afcwxv21c7fd0v3byyyrcpssrl31atxmpr-efttpngimumxw80wnhgsq");         sdkconfig.put("acct1.appid", "app-80w284485p519543t");          service = new adaptivepaymentsservice(sdkconfig);          payresponse payresponse = null;          // ## making api call         // invoke appropriate method corresponding api in service         // wrapper object         payresponse = service.pay(payrequest);         logger.debug("-->" + payresponse.getpaykey());         logger.debug("-->" + payresponse.getresponseenvelope().getack()); 

the paykey returned successfully, after payment paypal page should shown user's authorization , sandbox link , (https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&paykey=paykey)

foe doing ,

     httpresponse.addheader("access-control-allow-origin", "*");         httpresponse.addheader("access-control-allow-methods", "get, post, delete, put");         httpresponse.addheader("access-control-allow-headers",                 "access-control-allow-origin,content-type, accept");          httpresponse.sendredirect(url + paykey);         return response.status(successresponse.getcode()).entity(successresponse).build(); 

the paypal palpage not shown , can see error in browser console,"https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_ap-payment&paykey=paykey"
geeting error, no 'access-control-allow-origin' header present on requested resource. origin 'localhost:8080' therefore not allowed access.

please let me know needs done redirected paypal page.

thanks, gayithri

afaik might chrome not support localhost go through access-control-allow-origin

to send access-control-allow-origin in header, try localhost in hostfile (c:\windows\system32\drivers\etc\hosts on windows, /etc/hosts on unixes) other domain, like:

127.0.0.1   localhost mydomain.com 

then if you'd access script using mydomain.com instead of localhost, call should succeed.
