Hello, I am new on Google App Engine;
I wrote some code which accesses a Google Spreadsheet through the provided GData Java API; everythings works well running in the Eclipse local Environment or running the code on a local Apache Tomcat Server; nevertheless, running the code on the Google App Engine (deployed through Elipse) fails with the following error: Error: Server Error The server encountered an error and could not complete your request. If the problem persists, please report your problem and mention this error message and the query that caused it. the App Engine log gives me the following information: Uncaught exception from servlet java.lang.RuntimeException: java.io.NotSerializableException: com.google.gdata.client.spreadsheet.SpreadsheetService at com.google.apphosting.runtime.jetty.SessionManager.serialize(SessionManager.java: 361) at com.google.apphosting.runtime.jetty.SessionManager.createEntityForSession(SessionManager.java: 341) ... Any idea what I am doing wrong; thank you in advance for your help; Best Regards Rudolf -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
