webMathematica 3 implements revolutionary capabilities—including instant interactivity—for server-based web deployment. Included too are a range of enhancements for optimizing high-traffic sites.
webMathematica 3 replicates the automated instant interactivity Manipulate command for webpages. You can create webpages that contain various GUI features such as sliders, checkboxes and popup menus, which control calculations. All of this is done with the same concise syntax provided by Manipulate.
Expression Language and Custom Tags
webMathematica 3 allows more-concise calls to Mathematica from webpages. It also contains a library with a number of useful tags that provide valuable tools, such as redirecting flow as the webpage is generated.
webMathematica 3 has a new queuing system for long-running or asynchronous computation jobs.
Support for Wolfram Workbench
Wolfram Workbench provides a significant number of features that help accelerate the development of webMathematica content. webMathematica 3 integrates with Wolfram Workbench so that Mathematica code can be debugged as it runs in the server.
webMathematica 3 enables you to provide REST and SOAP web services that use Mathematica.
New Logging System
A new, highly configurable logging system helps to track different types of errors and to identify problems so that they can be resolved easily.
Improved Kernel Monitor
The Kernel Monitor has been significantly improved. It has new code for monitoring memory usage, run time, concurrent requests and Java objects, to help improve server reliability. It allows starting and stopping of individual kernel pools and canceling individual computations. Queued jobs are monitored for progress and errors.
Improved Kernel Interaction
webMathematica 3 interacts with the Mathematica kernel in improved ways. It launches kernels as soon as the server starts and launches all kernels in parallel, which helps improve server startup time. It also has a number of new configuration tools that can limit kernels' use of time and memory and improve server reliability. Kernels are automatically restarted in the background, so service remains uninterrupted.
