JavaEE 6: EJB Webservices in war

This is a new series of blogs which will cover what is new in JavaEE 6 with respect to WebServices One of the new features of JavaEE 6 is ability to package ejb in a war. The EJB specification has always required that enterprise beans be packaged in an enterprise module called an ejb-jar file. Since it is common for Java EE web applications to use enterprise beans, this packaging requirement can be burdensome. EJB 3.1 addresses this packaging complexity by removing the restriction that enterprise bean classes must be packaged in an ejb-jar file. You can now place EJB classes directly in the .war file, using the same packaging guidelines that apply to web application classes. This means that you can place EJB classes under the WEB-INF/classes directory or in a .jar file within the WEB-INF/lib directory. The EJB deployment descriptor is also optional. If you need it, you can package the EJB deployment descriptor as a WEB-INF/ejb-jar.xml file.  So we extend the above idea to demonstrate ejb webservices in a war file. The following blog shows how simple it is to create and deploy ejb webservices in war using Netbeans 6.9 (http://netbeans.org) and Glassfish 3.0.1 (https://glassfish.dev.java.net/downloads/3.0.1-final.html) Lets begin by creating a Web Application using Netbeans 6.9  Next we specify the project location    Select Glassfish 3.0.1 which is bundled with Netbeans 6.9 as the server. Note I use JavaEE 6 a...
