top of servlet engine, and you should use servlet engine's port number, such as 8080 or 8888.

+ !!Selection lists: enum implementation
+ 
+ This type of selection list outputs a list of items corresponding to the possible instances
of an enumerated type (see below).
+ 
+ Example:
+ 
+ {{{
+ <wd:selection-list type="enum" class="com.example.Sex"/>
+ }}}
+ 
+ outputs:
+ 
+ {{{
+ <wi:selection-list>
+   <wi:item value=""/>
+   <wi:item value="com.example.Sex.MALE">
+     <wi:label>
+       <i18n:text>com.example.Sex.MALE</i18n:text>
+     </wi:label>
+   </wi:item>
+   <wi:item value="com.example.Sex.FEMALE">
+     <wi:label>
+       <i18n:text>com.example.Sex.FEMALE</i18n:text>
+     </wi:label>
+   </wi:item>
+ </wi:selection-list>
+ }}}
+ 
+ If you don't want an initial null value, add a __nullable="false"__ attribute to the __wd:selection-list__
element.
+ 
+ |enum|Enumerated type|enum
+ !!Enumerated datatypes
+ 
+ The __enum__ datatype is meant to be used with types implementing Joshua Bloch's [typesafe
enum pattern|http://developer.java.sun.com/developer/Books/shiftintojava/page1.html#replaceenums].
    The following is a possible implementation:
+ 
+ {{{
+ package com.example;
+ 
+ public class Sex {
+ 
+     public static final Sex MALE = new Sex("M");
+     public static final Sex FEMALE = new Sex("F");
+     private String code;
+ 
+     private Sex(String code) { this.code = code; }
+ }
+ }}}
+ 
+ The following snippet shows the usage of this type:
+ 
+ {{{
+ <wd:field id="sex">
+   <wd:label>Sex</wd:label>
+   <wd:datatype base="enum">
+     <wd:convertor type="enum">
+       <wd:enum>com.example.Sex</wd:enum>
+     </wd:convertor>
+   </wd:datatype>
+   <wd:selection-list type="enum" class="com.example.Sex"/>
+ </wd:field>
+ }}}
+ 
+ If your enumerated type does not provide a {{toString()}} method, the enum convertor will
use the fully qualified class name, followed by the name of the {{public static final}} field
referring to each instance, i.e. {{"com.example.Sex.MALE"}}, {{"com.example.Sex.FEMALE"}}
and so on.
+ 
+ If you provide a {{toString()}} method which returns something different, you should also
provide a {{fromString(String, Locale)}} method to convert those strings back to instances.
+ 
+ The enum datatype is typically used together with the __enum__ selection list type.
