This is appearing very similar to an issue I had in my dev environment
when I had not enabled Java 5 compatibility. I suggest taking a deep
look at the exact Java version running the code and any compatibility
options. I experienced the same difficulty getting an EventFeed object
from a BaseFeed due to the underlying use of generics, setting Java 5
compatiblity solved it straight off.

Hi,
I am still experiencing the problem described in my first posting. My
GData libraries are contained in the WEB-INF/lib folder and it appears
that the JSP files can see them, because if I remove the JAR files from
the lib folder, I get errors saying the classes are not found on
import. I am uploading all production files to a web host's server,
which runs Resin 2.1.13 and JDK 1.5.0. Because it is a web host I am
connecting to, I do not think I have access to the CLASSPATH or
container-wide library directories, which would lead me to believe that
there wouldn't be an issue there. On my test server at home, I am
running the same version of Resin and Java and am experiencing no
errors.
I was going back to basics and was trying to run a simple script from
the Calendar API tutorial. Here is the code I was running:
// Set up the URL and the object that will handle the connection:
URL feedUrl = new
URL("http://www.google.com/calendar/feeds/[EMAIL PROTECTED]/private/full");
GoogleService myService = new GoogleService("cl",
"exampleCo-exampleApp-1");
myService.setUserCredentials("[EMAIL PROTECTED]", "mypassword");
// Mark the feed as an Event feed:
new EventFeed().declareExtensions(myService.getExtensionProfile());
// Send the request and receive the response:
EventFeed myFeed = myService.getFeed(feedUrl, EventFeed.class);
%><h3><%=myFeed.getTitle().getPlainText()%></h3>
And here is the response from the web server upon execution:
500 Servlet Exception
Note: sun.tools.javac.Main has been deprecated.
/connect/calendar_test.jsp:59: Incompatible type for declaration.
Explicit
cast needed to convert com.google.gdata.data.BaseFeed to
com.google.gdata.data.extensions.EventFeed.
EventFeed myFeed = myService.getFeed(feedUrl, EventFeed.class);
^
1 error, 1 warning
I have been explicitly casting here on my other calendar JSP app, e.g.
CalendarEventFeed myFeed =
(CalendarEventFeed)myservice.getFeed(feedURL, EventFeed.class); but I
should not have to do so according to the Calendar API tutorial example
above. What does this error message mean? I am not sure but perhaps
it is linked my main problem.
Any help is appreciated, as I am going CRAZY!
Thanks,
Mike
