Can I add new features that are not implemented in H-Sphere?
We provide open API to a few modules that can be used to add your own classes. For example, you can create your own CC processor by subclassing the Merchant gateway class.
How can you help me if I choose to add a product which is not supported by H-Sphere?
If you choose to add support to any of unsupported products, such as servlets or JSP, you would have to do it by yourself at your own risk. We can tell you whether or not this installation will mess with H-Sphere if you tell us what this installation will take in your specific case. This means, we would need from you a step-by-step plan of what exactly you are going to do to your system in respect to this installation.
