Google AppEngine gives Jersey ServletContainer ClassNotFoundException

Question

I am using Eclipse Indigo with Google AppEngine SDK (and no GWT)

Project setup starting with a clean default project:

• Java in use is the Oracle JDK 7 but changed project settings to generate 1.6 code and source code compatibility also set to 1.6
• Added 2 external jars to BuildPath from Glassfish Java EE 6 + JDK 7 installation
• jersey-core.jar
• jersey-gf-server.jar
• jersey-gf-server.jar contains com.sun.jersey.spi.container.servlet.ServletContainer
• Fixed Eclipse markers complaining that the jar files would not be found in the deployed app -- accepted suggested fix for each to copy them to war/WEB-INF/lib folder
• Deployed successfully
• Upon accessing the regular non-Jersey hello-world servlet, I get the error in AppEngine logs: java.lang.ClassNotFoundException: com.sun.jersey.spi.provider.container.servlet.ServletContainer

Answer 1

You should add jersey-servlet.jar as well. At some point this class was migrated there.

Answer 2

the class ServletContainer is in the jersey-bundle.jar
