This document discusses automatically generating JSON from Java objects using the org.json Java utilities. It begins with an introduction and setup information for using the utilities. It then covers the general approach of setting headers, getting data from business logic, and turning Java objects into JSONObjects or JSONArrays. Examples are provided of turning a Java bean into a JSONObject and building a JSONArray from a list of beans. The benefits and limitations of automatically generating JSON are compared to manually building JSON on the server.
The document discusses new features in Java 7 including fork/join concurrency and invokedynamic. Fork/join concurrency allows tasks to be recursively split into subtasks to take advantage of multiple cores. Invokedynamic is a new bytecode that allows method calls to be resolved at runtime rather than compile-time, improving performance of dynamic languages on the JVM. It works by triggering a bootstrap method to lookup and return a method handle for the actual implementation.

HCL Notes and Domino License Cost Reduction in the World of DLAUpanagenda
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away
