You're using an IDENTITY value as the key. By definition, that's an automatically generated, incremented value. But you don't have to use IDENTITY: http://code.google.com/appengine/docs/java/datastore/creatinggettinganddeletingdata.html#Creating_and_Using_Keys You have to specify a different constant instead of IdGeneratorStrategy.IDENTITY: http://db.apache.org/jdo/api21/apidocs/javax/jdo/annotations/IdGeneratorStrategy.html Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ http://training.figleaf.com/ Fig Leaf Software is a Veteran-Owned Small Business (VOSB) on GSA Schedule, and provides the highest caliber vendor-authorized instruction at our training centers, online, or onsite. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
