in list 2.16 hello word main class


// Deploy all EJBs found on classpath (fast, scans only build directory)
// This is a relative location, matching the substring end of one of java.class.path locations!
// Print out System.getProperty("java.class.path") to understand this...
EJB3StandaloneBootstrap.scanClasspath("helloworld-ejb3/bin");
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

should be

EJB3StandaloneBootstrap.scanClasspath("helloworld-ejb3/build");


or EJB3StandaloneBootstrap.scanClasspath();


when I try this example , if I use EJB3StandaloneBootstrap.scanClasspath("helloworld-ejb3/build") ,I got exception for jndi name find MessageHandlerBean/local ,use EJB3StandaloneBootstrap.scanClasspath() , it works

The book uses 'bin', the example source code for download uses 'build'. But each of them is consistent, so either type in all the code and the build script from the book or use the existing source code and build script.
