You are running it on a Device with that specific API ?
which device are you testing it on ?

Iam testing it on sonyericsson W910. I have doubt in providing provisioning information in MANIFEST regarding AMEX , VISA , MASTERCARD.
In this MANIFEST i had mentioned "Pay-AMEX-Info: X-CCARD, EUR, AMEX, [url]https://localhost[/url] " . But i think i need to mention the correct URL. Can you please suggest me the correct approach to this. Is there any other reasons for this issue?

Any reply or help would be beneficial for us also.
Please post here if any solution.

Cheers,
-Vikram.

Would like to know what exactly you are trying to do , i could see that you are adding [url]https://localhost[/url] in the manifest file, https is a secure protocol which requires certificates. Can you explain step by step what you did , and you say that it works on the emulator, wch emulator, and how does it connect to your server???

But when i try to run the same i get the following using emulator, application loads and ask Please execute using OTA... when i click continue it gives me the following...

For this application to work we need to add the these pay-attributes in JAD also.

I had executed thia app on SonyEricsson JP7 emulator.
In the documentation of payment api it is been mentioned that we need to add SOAP url's in pay-provider-info title. In this application i just mentioned [url]https://localhost[/url] with this is working fine on emulator.
I want to know more about this.

Iam very thankful if you could provide any information on this.

From where did you find the api documentation, i have been searching it .. can you provide link for the same, and also which server are you hitting with the emulator, https only listens on 443....

Are u sure the device supports Payment api ? or web services api -- i guess u need that for the soap part

[url]http://jcp.org/en/jsr/detail?id=229[/url]

From this link i had downloaded the document

ya iam sure that the device supports these two apis. I have a test app for that and also i have a document that lists the supported JSrs for all mobiles

When it works from the simulatoro tht means it connects to the payment adapter, which a dummy adaptor for testing purpose. And also when you put onto the device it will not connect because it says that the PSMS should be available from the operator. When you see the Jbricks example in the WTK(wireless toolkit) you will come to know exactly what is happening, you can also view the adaptor logs from here.
I think there is still lot of research should be done how to contact the operator and how it works etc. I hope this has answered your question.

Yes exactly this is the point where i had stucked. I had started developing this app learning from JBricks only. The JBricks app is also making use of a dummy.
So i could n't get more information on this issue from JBrich=ks app.
I will be really thankful to you if you could provide more information on how to contact the operator and how to make my applicatio to work on device .

Thanks in advance.

I dont think operator's support this , i am not sure you need to check, the other way around would be to connect to a payment gateway.
and have a secure communication between midlet and the server....

can u please give any example or some useful links to proceed further
