I'm attempting to walk through the examples to provide some guidance for new Google App Engine developers here. As far as I can tell the latest examples are here:
http://googcloudlabs.appspot.com/ Unfortunately even as early as Code Lab Exercise 1, following the instructions does not lead to a successfully executing app. This is true even if one downloads the completed exercise (in CodeLabEx1.zip) and executes it per instructions in Appendix A. The errors seem to resolve around java.lang.NoClassDefFoundError errors getting thrown when accessing classes, including those which are built in the project, such as Util.java. Is there an additional configuration step that is missing from the lab documentation that I can graft in for new developers? This is happening both on the instance being deployed to the cloud as well as those run locally. An example of this exception can be generated by simply bringing up the website and navigating to the "Product" tab. In the log you will see the error message and stack trace: java.lang.NoClassDefFoundError: com/google/appengine/api/datastore/ EntityNotFoundException at com.google.appengine.codelab.Product.getAllProducts(Product.java: 40) at com.google.appengine.codelab.ProductServlet.doGet(ProductServlet.java: 53)... where the offending line is: return Util.listEntities(kind, null, null); Any insight group members can provide into this would be appreciated.
