NoClassDefFound means that the class cannot be found?

I don't understand NoClassDefFoundError in the context of running an OpenEJB client:

thufir@doge:~$ 
thufir@doge:~$ java -classpath .:NetBeansProjects/HelloClient/dist/HelloClient.jar:apache-openejb-4.7.1/lib/openejb-client-4.7.1.jar org.acme.HelloClient
Exception in thread "main" java.lang.NoClassDefFoundError: javax/ejb/EJBHome

The missing class, EJBHome, is in the libray for the project:

libraries

Yet doesn't show up in the manifest. How do I either force NetBeans to add the JAR to the classpath (if that's the solution), or, include the JAR in the classpath during execution?

NoClassDefFoundError means that the class was present at compile time, but is not present at run time. So probably your deploy has'nt that class.

You include the jar file in the classpath when you execute by simply putting it in that list of jar files you've already got - you're already specifying openejb-client-4.7.1.jar etc; just add javaee-api-7.0.jar to that list (with the right directory, of course).
