Problem is due to libraries required when project is run are in war/ WEB-INF/lib and libraries used during build are from java library path (project settings). And there are no easy ways to sync unless you are Eclipse guru and can manage to write Ant script to update web libraries using project variables.
For EAR projects J2EE Module Dependencies can solve jar sync problem (http://www.eclipse.org/webtools/releases/1.5/newandnoteworthy/ j2ee.html) but Google Web Application project is not EAR project. Again Eclipse gurus can do some magic here editing .project file by hand. Simple problem resoluton for mortals follows. 1. Change errors to warnings Window/Preferences from menu Google Errors/Warnings Expand "Project structure and SDKs" SDK JAR missing from WEB-INF/lib : select Warning in combo 2. Delete old jars from war/WEB-INF/lib. Delete these jars from war/WEB-INF/lib (except gwt-servlet.jar): appengine-api-1.0-sdk-1.2.1.jar datanucleus-appengine-1.0.1.final.jar datanucleus-core-1.1.0.jar datanucleus-jpa-1.1.0.jar geronimo-jpa_3.0_spec-1.1.1.jar geronimo-jta_1.1_spec-1.1.1.jar jdo2-api-2.3-SNAPSHOT.jar You still will be able to compile project but not run it because jetty web server will look for libraries in WEB-INF/lib. 3. Copy missing jars of required versions to WEB-INF/lib. Simpliest way is to copy all files from: (eclipse)\plugins\com.google.appengine.eclipse.sdkbundle. 1.3.2_1.3.2.v201003241245\appengine-java-sdk-1.3.2\demos\guestbook\war \WEB-INF\lib (eclipse) is location where your eclipse is installed. Macs and Linuxes should replace \ to / in file path 4. Refresh folder in Eclipse In Eclipse, select war/WEB-INF/lib, Refresh to refresh folder contents. 5. Now fix your Eclipse settings to avoid running into the same problems again. Window/Preferences from menu Google App Engine Check latest SDK version Google Web Toolkit Check latest GWT version PS. And now Google suggests to upgrade to release 1.3.3 :) -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
