java.lang.Object org.apache.tools.ant.taskdefs.optional.ejb.GenericDeploymentTool
public class GenericDeploymentTool
A deployment tool which creates generic EJB jars. Generic jars contains only those classes and META-INF entries specified in the EJB 1.1 standard This class is also used as a framework for the creation of vendor specific deployment tools. A number of template methods are provided through which the vendor specific tool can hook into the EJB creation process.
