Since you are receiving a NoClassDefFoundError, you would need to check your classpath for the client application. Make sure that you have the Weblogic JAR and the EJBClient JAR (containing the home and remote interfaces) set in the classpath.
I am not sure if your JNDI name "java:comp/env/ejb/myjndi2" would work in this case, since your application is not a part of the application container. You would need to use the global JNDI name for the EJB (which is set in weblogic-ejb-jar.xml)
