I just signed up for a Authorize.Net test account, and then I downloaded the SDK, installed it into my Tomcat server, and configured the helper.jsp with my test account information, but when I submit the “coffee shopping cart” example they give, it gives me an error that is really vague and I can’t figure it out. Any ideas on how I can debug this?
We're sorry, but we can't process your order at this time due to the following error:
Transactions of this market type cannot be processed on this system.
response code 3
response reason code 87
The response code documentation is here:

Sounds like you got a retail test account and not an ecommerce test account. Either get a new test account for ecommerce or see if you can get Authnet to change the account type for your current test account.
