I have a web application that contains a GWT module. In the client of my GWT module I want to use the library "com.google.appengine.api.datastore.DatastoreService" but, when I compile the gwt module, I have this error: "The import com.google.appengine.api.datastore cannot be resolved". Where is the problem

The first and most obvious things to ask are: Have you downloaded the java appengine SDK and have you made the JAR files contained within available to your app? Are you using Eclipse?
第一个也是最明显的问题是:您是否已下载了java appengine SDK并且是否已将包含在其中的JAR文件提供给您的应用程序?你在用Eclipse吗?

I don't think it is possible. Anything on the client side gets translated to javascript that is ran in the browsers. You can directly access a database through javascript in the browser. Not all Java code can run in a browser. In fact not even all the JRE classes can be used either. If you need a type of storage on the client side, look at html 5 local storage.
