I see from the discussion that WSDL2Java is able to convert simple enumerated types into Java static final values.
However when I run Java2WSDL in the first step of creating my webservice the public final static fields do not get created in the WSDL. Is this the expected behaviour?
If I want enumerated types available to my client do I need to manually edit the WSDL after running the Java2WSDL tool?
Thanks, Stuart.

OK -- I found the "magic!" Does not seem to be documented, but in one of the tests for Axis I found this:
<!-- The following test all of the valid enum basic types -->
<xsd:simpleType name="enumString">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="Ho Ho Ho"/> <!-- Blanks should force
value<1..n> names --> <xsd:enumeration value="He He He"/> <xsd:enumeration value="Ha Ha Ha"/> </xsd:restriction>
Ergo, if one does not have any spaces in any of the enumerated values, then it will automatically generate useful values. IMHO, one should simply replace spaces with _ and generate HO_HO_HO instead of VALUE1.

Hi Albert,
OK -- that makes a bit of sense although the type-safe "feature" then
means it is not compile-time "safe" since you cannot use the static
variables (unless you want to use the NotificationType._value1, ...).
What I see, in practice, is things like:
nhq.setNotificationType(org.jtc.wo.NotificationType.fromString("data
delivery"));
instead of something that can be checked at compile time such as:
nhq.setNotificationType(org.jtc.wo.NotificationType.DATA_DELIVERY);
If the names were such as what I show instead of the _value1 pattern,
then the enumerations would be much more useful at compile time.
Best,
Joe

This is because wsdl2java generates "typesafe enums" for each enumeration. Basically, rather than just creating a series of "static final" constants, it creates objects for each enumeration, which has a major advantage of preventing you from assigning an invalid value to an enumeration.
A good description of typesafe enums is here: http://developer.java.sun.com/developer/Books/shiftintojava/page1.html

Enumerations using wsdl2java get created (in my opinion) brain-dead.
Is there a reason for (or a work around) the way that wsdl2java creates the static final parameters with names like Color._value1, Color._value2, etc. rather than something that could be useful such as
Color.RED, Color.BLUE, etc.?
Best,
