Mobile application s/w is java .this is front end of the process.

Web server s/w is php.this is back end of the process.

My question is that how to send the request from mobile application to web server using java and also how to get that request and send response for that to mobile application from web server using php and also read response by java in front end.

Please reply me asap.
