Communication between two websites
I would like to know about how to send data across two wesites.
the scenario goes like this i have 2 websites A & B.
A does registration and B does enrollment.
Once A finishes registration of a user i have to pass the registered user details to B which will make enrollment for the same registered user. Once the enrollment is done B has to acknowledge A about the completation.
lot of security concerns are there, but the aboe basic fact of communicating is my doubt.
Can i do this using JMS, one more problem is B is an external site and i am not sure whether B uses JMS or not
Help any will be appreciated....

Hi,
Not sure how A does registration.. through a GUI and whether it uses servlets. If A & B are both using servlets then you may pass registration details from A to B using HttpUrlConnection class in java.net package.
Further as you said B must send acknowledgement to A about completion of enrolment. Then it is will be better idea to use a synchronous callback. i.e. A waits untill B completes enrollment.

Hi,
Is it not possible to find out. I mean as you want these two websites talk to each other then you must know.
However if you must wait untill B confirms enrollment then I feel using
JMS may not be a good option. From website B you can expose a webservice, which will accept registration data from A and then confirm the enrollment.

i can find out about B but, i can only implement on A side B is like a third party i can just know about them but can't implement anythin on B.
thanks for the suggestion but i have no idea about web services, even i started with JMS recently, can u suggest me some good resources for web-services and suggestions any are welcome

Hi,
I think your approach does not seem to be practical for following reasons.
1. From 'A' you need to pass registration data to 'B'. So you must be aware of how B expects this data if not then B must let you know this.
2. A must wait untill B confirms enrollment. Then you must know how B is going to reply back to A.
3. This, if has been thought about during construction of B then, there must be some kind of interface/service that is available on B.
4. If there is no service available on B then it must be created.
5. The role of A essentially is that of a client who is going to use the service provided by B.
6. So find out if there is any existing interface/service available in B, if not then expose a new one.
You can find some good articles on web services using Google or then
java.sun.com has some webservice tutorials.
Please let me know if you need any further help.
