This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up with different versions on classes on the class path).

The newest version!

/**
 * This class is necessary to break the following cyclic dependency:
 * 
 * JNI_OnLoad
 * JNI Calls FindClass because RegisterNatives (used to register JNI methods) requires a class
 * FindClass loads the class, but static members variables of that class attempt to call a JNI method which has not
 * yet been registered.
 * java.lang.UnsatisfiedLinkError is thrown because native method has not yet been registered.
 * 
 * Static members which call JNI methods must not be declared in this class!
