Google announced the new features for Google App Engine (GAE), but the most important one is the support for Java. Java Developers can use GAE for their applications with small changes. (may be big changes due to datastore restrictions )
10.000 developers can have an early access to GAE for Java through this link : http://appengine.google.com/promo/java_runtime
There are also additional feautures as :
- App Engine’s early look at Java™ language support includes a Java runtime, integration with the new Google Web Toolkit 1.6, and a Google Plugin for Eclipse
- The Google Secure Data Connector enables centrally-managed access to on-premise data from Google Apps
- The database import tool makes it easier to move gigabytes of data into App Engine (and export functionality is coming within the month)
- Cron support can execute scheduled tasks like report generation and DB clean-up at regular interval.
This new announcement may lead to change in GIS area, like implementing the GeoServer for GAE or other 3th party GIS tools for GAE
