Title: Built-in Type Converters
The following built-in types are supported for @Resource injection in EJBs
via <env-entry> elements in a META-INF/ejb-jar.xml or via plain properties
in a META-INF/env-entries.properties file.

EJB 3.0 required types:

 - java.lang.Boolean
 - java.lang.Byte
 - java.lang.Character
 - java.lang.Double
 - java.lang.Float
 - java.lang.Integer
 - java.lang.Long
 - java.lang.Short
 - java.lang.String

OpenEJB 3.0 additional types:

 - java.lang.Class
 - java.lang.Enum (any subclass of)
 - java.io.File
 - java.math.BigDecimal
 - java.math.BigInteger
 - java.net.Inet4Address
 - java.net.Inet6Address
 - java.net.InetAddress
 - java.net.URI
 - java.net.URL
 - java.util.ArrayList
 - java.util.Date
 - java.util.HashMap
 - java.util.Hashtable
 - java.util.IdentityHashMap
 - java.util.LinkedHashMap
 - java.util.LinkedHashSet
 - java.util.LinkedList
 - java.util.List
 - java.util.Map
 - java.util.Properties
 - java.util.Set
 - java.util.SortedMap
 - java.util.TreeMap
 - java.util.TreeSet
 - java.util.Vector
 - java.util.WeakHashMap
 - java.util.logging.Logger
 - java.util.regex.Pattern
 - javax.management.ObjectName
 - javax.naming.Context
 - org.apache.commons.logging.Log
 - org.apache.log4j.Logger

To use an OpenEJB additional type in xml, simply declare it as
<env-entry-type>java.lang.String</env-entry-type> and it will be converted
on the fly to the field/setter type used by the bean class.  For example:


    package org.superbiz.foo;
    
    import java.util.Date;
    
    @Stateless
    public class MyBean {
    
        @Resource
        private Date myDate;
    }


Works with an ejb-jar.xml as follows:

    <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" version="3.0"
    metadata-complete="false">
      <enterprise-beans>
        <session>
          <ejb-name>MyBean</ejb-name>
          <env-entry>
      <env-entry-name>org.superbiz.foo.MyBean/myDate</env-entry-name>
      <env-entry-value>2008-04-19</env-entry-value>
      <env-entry-type>java.lang.String</env-entry-type>
          </env-entry>
        </session>
      </enterprise-beans>
    </ejb-jar>

    
Or with an env-entries.properties file as follows:

    org.superbiz.foo.MyBean/myDate = 2008-04-19
