[appengine-java] Re: Google checkout and GAE

2011-04-28 Thread Patrick Jackson 
I'm just having problems getting the custom order processing tutorial to 
work.
  Has 
anyone had luck with this?  I get the following errors:

Error for /myapp
java.lang.NoClassDefFoundError: 
com/google/checkout/sdk/commands/EnvironmentInterface
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2406)
at java.lang.Class.getConstructor0(Class.java:2716)
at java.lang.Class.newInstance0(Class.java:343)
at java.lang.Class.newInstance(Class.java:325)..

Any suggestions?  Just trying to receive notifications of new purchases at this 
point.

Take a step back for a second:

Can someone explain why the SDK doesn't work *at all*?  The last
checkin was September 2010.  There are several missing classes; it's
broken out of the box.

Can someone explain why the SDK doesn't work on app engine.  Does it
use a library that's not on the white list? Is it just broken in
general and doesn't work well anywhere?
