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).

There is a newer version: 33.0.2.Final

/**
 * Defines a functor interface implemented by classes that perform a predicate
 * test on an object.
 * 
 * A Predicate is the object equivalent of an if statement.
 * It uses the input object to return a true or false value, and is often used in
 * validation or filtering.
 * 
 * Standard implementations of common predicates are provided by
 * {@link PredicateUtils}. These include true, false, instanceof, equals, and,
 * or, not, method invokation and null testing.
