Hello, I fixed above mentioned problem by a more accurate design of my Servlets; the code is now executing on GAE;
nevertheless, now I face another problem; the data calculation for the response on the GAE takes more then 30 seconds; at about 30 seconds GAE kills my request; I found a lot of threads in the Web on this issue, but not the information I have looked for; is it possible to tell GAE, that a request takes more then 30 seconds? it is difficult to split my application into different requests, since within one request I have to get the data of a Spreadsheet (more than 6000 data records) for the calculation of a result; this event will eventually take more then 30 seconds; any idea how I can handle this; thanks in advance for your help; Best Regards Rudolf On 4 Mai, 18:10, Rudolf <rudolfstolz...@googlemail.com> wrote: > Hello Ikai, > > I have a mix of functions which read or write data from/to a > Spreadsheet; > > I fail on both; > > Best Regards > Rudolf > > On 4 Mai, 11:06, "Ikai L (Google)" <ika...@google.com> wrote: > > > > > > > Are you storing something in the session, such as an instance of the GData > > client? > > > On Mon, May 3, 2010 at 7:20 PM, Rudolf <rudolfstolz...@googlemail.com>wrote: > > > > 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. > > > To post to this group, send email to > > > google-appengine-j...@googlegroups.com. > > > To unsubscribe from this group, send email to > > > google-appengine-java+unsubscr...@googlegroups.com<google-appengine-java%2bunsubscr...@googlegroups.com> > > > . > > > For more options, visit this group at > > >http://groups.google.com/group/google-appengine-java?hl=en. > > > -- > > Ikai Lan > > Developer Relations, Google App Engine > > Twitter:http://twitter.com/ikai > > Delicious:http://delicious.com/ikailan > > > ---------------- > > Google App Engine links: > > Blog:http://googleappengine.blogspot.com > > Twitter:http://twitter.com/app_engine > > Reddit:http://www.reddit.com/r/appengine > > > -- > > You received this message because you are subscribed to the Google Groups > > "Google App Engine for Java" group. > > To post to this group, send email to google-appengine-j...@googlegroups.com. > > To unsubscribe from this group, send email to > > google-appengine-java+unsubscr...@googlegroups.com. > > For more options, visit this group > > athttp://groups.google.com/group/google-appengine-java?hl=en.-Zitierten > > Text ausblenden - > > > - Zitierten Text anzeigen - > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine for Java" group. > To post to this group, send email to google-appengine-j...@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine-java+unsubscr...@googlegroups.com. > For more options, visit this group > athttp://groups.google.com/group/google-appengine-java?hl=en.- Zitierten Text > ausblenden - > > - Zitierten Text anzeigen - -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
