You can do that via Paypal Developer Tools.
Specifically with a Sandbox Test Account and the paypal API.
It will be from your end the same as a real paypal credit card transaction. I haven't used it with Java so I can't comment on any specific tricks to make it work best for that. If after reading those docs you get stuck at all I'd suggest asking a ...
Have a look at https://stripe.com/, they have a pretty straight forward API. They offer a variety of SDKs and it is also possible to use CURL.
Regarding your requirements:
That is what a payment provider does, it stores all payment data for you, so you do not have to worry about PCI Standards and other Security Issues.

osCommerce is an e-commerce website I have built a website with.
lists of products, categories
plugins for tons of credit cards
easy to maintain your product catalog thanks to the admin interface
very popular software, so many developers know it, lot of documentation.
Email confirmation would be too brittle, and susceptible to forged emails.

The details for setting this up are here:
This is a free feature, and doable even with a ...
I used drupal with its modules userpoints, userpoints ubercart, userpoints, and other dependent modules, for a very similar use case. This was done using drupal7 and still works today, and will suit the schools use case.
each school will be set up as a user
users can be allocated points by the admin person.
you can rename points to tokens if required.

Gimp is free and includes 3D transformations and scripting in either python or script-fu. You should be able to replate the workflow that you already have in such a script and have it prompt you for the dimensions and/or text, etc. reasonably simply.

registration of user is standard on drupal

Stripe Connect is actually the better-known brand for this, but as you say it can get expansive for your use-case.
Other than that are not many good options. The best one I could find is the Dwolla Facilitate option, which they describe as:
Provide the interface that allows your users to send funds to each other via Dwolla

From what you have suggested I would maybe look at the following:
Stripe - This has an easy sign-up process and hosted payment options to reduce the PCI compliance issues and ideal for low volume. It's also very popular so there are a number of integrations avilable for it.
Braintree Payments - A little like stripe, maybe aimed at higher volume, but not as ...

MailChimp/Campaign Monitor all allow for multiple lists...
Two problems it seems:
Charging visitors before they are added to a mailing list service

I have heard good words about litecart. It's simple it runs in PHP, HTML5 and jQuery and seems to have faster files and database table to manager than the most common eShop Packages.
Have a look
I've wrote a class as part of the Drupal module. See project home page, main repository and mirror on GitHub.
