Software and Data With the improved performance and optimization tools available in ArcGIS 9.3.1, informative and responsive Web maps can be more easily configured and deployed. ArcGIS Engine (Java SE) and ArcGIS Server (Java EE) platforms will be able to create the following extensions: n Custom geoprocessing tools n Server object extensions (SOEs) for ArcGIS Server n Class extensions for custom behavior n Custom renderers for customized rendering of data n Plug-in data sources n Custom layers Eclipse integrated development environment (IDE) support will also be provided in wizards that will generate boilerplate code based on the developer specifications. This will facilitate quick and easy development of extensions. ArcGIS 9.3.1 will also include an autodeploy feature that will allow Java developers and their end users to automatically deploy Java extensions. Other Features for Developers ArcGIS 9.3.1 fully supports Microsoft Silverlight to allow developers to create rich Internet applications (RIAs) that incorporate animation, vector graphics, and audio-video playback. Upgrade Easily Users who have ArcGIS 9.3 installed can upgrade to ArcGIS 9.3.1 without uninstalling ArcGIS 9.3. ArcGIS 9.3.1 is 100 percent compatible with ArcGIS 9.3 for all aspects of ArcGIS (including geodatabases, maps, and APIs), so users can easily migrate or work in environments where both versions are in use. ArcGIS 9.3.1 Seminar on Configuring and Deploying Effective Web Maps In May 2009, Esri will offer a free, nationwide seminar to help ArcGIS users learn how to easily create high-quality, fast Web applications. This seminar will show users, step by step, the best practices for creating efficient map services and focused Web applications using new optimization and configuration tools and sample applications available with ArcGIS 9.3.1.
