ArcGIS Engine和Server開發文檔相比微軟MSDN遜色不少，前者經常需要尋找AO for VB的協助，後者不少主題還是空白，開發人員對ESRI開發文檔是抱怨聲不斷，好在ESRITeam Dev在不停更新與維護，這次更新主要集中在ArcEngine for Java SDK，包括文檔和程式碼片段：
- Finding locations with geocoding offers topics detailing the ins and outs of assigning a location to an address.
- Next is the Geodatabase management section with a multitude of topics discussing such things as How to create new geodatabases, How to query geodatabase objects, How to create a multimodal network dataset, How to check for topology error features in a geodatabase topology, How to convert simple data to a geodatabase, and How to export a dataset to an XML workspace document among other things.
- Key to working with ArcGIS is understanding Geometry and spatial reference. This section includes topics on When do I need to simplify a geometry, Understanding coordinate management in ArcGIS, How to convert between high and low precision spatial references, and many more.
- Geoprocessing puts powerful analysis capabilities at your fingertips. Learn how to access geoprocessing tools and toolboxes, use ArcObjects as an input to a tool, and generate your own custom geoprocessing tool.
- The Mapping and visualization section deals with--you guessed it--maps, map display, layers, page layouts, symbols, renderers, and more.
除此之外，還有其他內容更新，how to leverage the schema cache，介紹了如何最好的使用AO應用中的schema cache，對schema緩衝可以減少geodatabase空間資料庫來回訪問次數，提高應用效率。Overview of ArcGIS Server application performance tuning更新了ArcGIS Server效能調優方法。
以往文檔更新一般會隨著軟體下一版本一起釋放出來，這次提前將文檔推出了，不過還需要繼續完善，希望9.3release版本能看到比較大的變化。
