I get *NoClassDefFoundError* when trying to use a class like com/google/api/client/googleapis/auth/oauth2/GoogleClientSecrets. I'm trying to use the Java Google Drive library in my GAE servlet. I tested the code in a standalone java app and with works. The java code compiles without complaint in Eclipse But when I try to run the servlet in the 'localhost' server in Eclipse, I get the NoClassDefFoundError. GoogleClientSecrets (just a convenient, arbitrary class to test on) is in * com.google.api.client.googleapis.auth.oauth2* in C:\app\gDrive\libs\* google-api-client-1.16.0-rc.jar* on my system. It appears in the 'Referenced Libraries for the project. Its in the Java Build Path as an external jar, (The jar is 'check' marked in the Order and Export tab of Eclipse Java Build Path dialog -- I think that means include this jar in the WAR file for the server.
The fact that Eclipse doesn't see an error when I refer to GoogleClientSecrets means to me that the Build Path has the class in it. There must be something I don't understand about the class loader environment for the 'localhost' 'server', or for the class loader for the servlet -- that is not finding the google-api-client-1.16.0-rc.jar. (The server starts fine, but when the servlet loads (when the first HTTP request is handled) I get the NoClassDefFoundError. *Are there any restrictions about classes or jars that GAE loads? Is there something different about the way the server/servlet class loader works?* -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
