Learn what’s new with Java on App Engine. We’ll take a whirlwind tour through the changes since last year, walk through a code sample for task queues and the new blobstore service, and demonstrate techniques for improving your application’s performance. We’ll top it off with a glimpse into some new features that we’ve planned for the year ahead.

Connecting The Clouds: Integrating Google App Engine for Java with Force.com
Published December 9th, 2009 Under Architecture, Open Source Tools, Services | Leave a Comment
In this session we will outline how to connect the Salesforce SOAP Web Services API to Google App Engine for Java. The project includes an open source Web Service Client that has been completely ported to App Engine. This client is designed for high performance and will work with Force.com WSDL’s or other WSDL’s that you may want to connect to. We will discuss the porting effort and demonstrate a simple integration between App Engine and the Salesforce.com. Appirio will demonstrate an advanced casino host application & game which blends App Engine and Salesforce. You’ll learn how both platforms can be developed on side-by-side within the Eclipse IDE.
The Softer Side Of Schemas – Mapping Java Persistence Standards To the Google App Engine Datastore
Published November 25th, 2009 Under Architecture, Coding | Leave a Comment
Google App Engine is a powerful cloud-computing platform designed to help developers more easily create and manage scalable web applications. With the recent addition of Java support, developers can now interact with the Google App Engine datastore using JDO and JPA, both standard Java persistence APIs. In this talk we will discuss how these standards allow you to create a “soft schema” on top of a schema-less datastore, and the advantages this soft schema provides. We will also explore how the datastore’s “pre-sharded” transactional model is exposed in these standard interfaces. Finally, we will discuss how a soft schema maps to a traditional, relational schema, and examine some techniques for porting persistence code on and off App Engine.
App Engine for Java: An Enterprise Cumulonimbus?
Published November 11th, 2009 Under Architecture, Open Source Tools, Services | Leave a Comment
Enterprise software pundits are now gazing metaphorically skyward. There’s all this talk of clouds, but what kind of clouds are coming, and will they be friendly? We begin by describing some applications we’ve developed for App Engine, including implementation of other languages, such as JRuby, on top of the App Engine for Java implementation. These implementations demonstrate the breadth of capability provided by App Engine. We then examine some of the strengths and current weaknesses that we encountered. We also describe more about the implications for testing that arise when developing on App Engine. We will also present an initial framework for characterizing these differnet clouds and examine how these characteristics will impact the adoption path for enterprises and the kinds of applications these enterprises will move to the cloud. Of particular interest here is the central role of Big Table in App Engine. Broad adoption of this of this platform could lead to lots of lightening striking at the dominant role relational data base systems currently enjoy.
