Getting Started?
To get started and take advantage of the new runtime and features, please make sure that you have the latest version of the Eclipse based SAP Cloud Platform Tools. Then the Java EE 7 Web Profile SDK can be configured in the Eclipse IDE for Java EE Developers using the standard way you are already familiar with.
In order to use the new runtime in the cloud, you may have to enable the Beta features for your subaccount.
Why Beta?
We want to collect as much as possible feedback from you and to learn more about the things you want to use and the way you want to use them. Therefore, in the beginning with the Java EE 7 Web Profile SDK you can deploy applications only in Beta and Trial accounts. We are eager to find out what you think about it! Please do not hesitate to share your experience, questions and feedback in our Community discussions forum.
What Comes Next?
In the coming months, we will focus on enabling the Java EE 7 Web Profile for productive usage. In the meantime, we will try and keep you blogged about technical capabilities and how-to guides – to keep you interested and to collect feedback on the application programming model and features. Stay tuned and actively participate in the conversation!
