Has anyone gotten JODA time classes to work on Google Appengine? I'm using 1.3.4 of the java sdk and I get the following error when trying:
java.lang.NoClassDefFoundError: com/google/appengine/repackaged/org/joda/time/DateTimeZone
I've imported it as well:
import com.google.appengine.repackaged.org.joda.time.DateTime;

Joda-Time provides a quality replacement for the Java date and time classes. Joda-Time is the de facto standard date and time library for Java prior to Java SE 8. Users are now asked to migrate to java. time (JSR-310).
Joda-Time is an API created by joda.org which offers better classes and having efficient methods to handle date and time than classes from java. util package like Calendar, Gregorian Calendar, Date, etc. This API is included in Java 8.0 with the java.
So the short answer to your question is: YES (deprecated).
Joda-Time provides support for multiple calendar systems and the full range of time-zones. The Chronology and DateTimeZone classes provide this support. Joda-Time defaults to using the ISO calendar system, which is the de facto civil calendar used by the world.
The real purpose of repackaged classes is for Google to have a private set of classes that they can use and that do not conflict with any known packages. Repackaged classes are not meant to be used by the public and if you do, you do at your own risk. They could be yanked at any time.
You can download JODA and just include it as a dependency, there should be nothing to stop it from working. The names will nor clash with Google's because of the different package.

Lots of people love joda too.
I suggest placing the JODA package jar in your lib directory and importing it directly.
import org.joda.time.DateTime;
