JAX-WS, @XmlJavaTypeAdapter, and a custom enum

Question

I am using a library that generates code based on IDL definitions. Its great to be able to use common enumerations in various languages (Java, C and C++), but these generated enums don't seem to play well with JAX-WS. Basically, main enum 'super' class has two members: ordinal and name. It looks similar to this (Note: this is in a third party library and is not JavaBean friendly) : ``` public class CustomEnum { int _ordinal; String _name; public CustomEnum(int ordinal, String name) { this._ordinal = ordinal; this._name = name; } public int ordinal() { return _ordinal; } public String name() { return _name; } } ``` So then in the generated code based on an IDL definition looks similar to this (Using Day as an example -- but in actuality I have about 50 'enums' that extend CustomEnum, so I'd like a solution that keeps me from having multiple copies of enums around such as an IDL generated type and a java.lang.enum): ``` public class Day extends CustomEnum { public static final Day Sunda…

Accepted Answer

EnumBean If `EnumBean` is the adapted class then it needs to have a default constructor. ``` package forum10972195; public class EnumBean { int ordinal; String name; public EnumBean() { } public EnumBean(int ordinal, String name) { this.ordinal = ordinal; this.name = name; } public int getOrdinal() { return ordinal; } public void setOrdinal(int ordinal) { this.ordinal = ordinal; } public String getName() { return name; } public void setName(String name) { this.name = name; } } ``` CustomEnumAdapter Also the adapted class should appear as the first parameter when extending `XmlAdapter`. Since the parameter you are mapping to is of type `Day` you are going to need to have the `XmlAdapter` specify `Day` as the bound type. ``` package forum10972195; import javax.xml.bind.annotation.adapters.XmlAdapter; public class CustomEnumAdapter extends XmlAdapter { @Override public EnumBean marshal(Day v) throws Exception { EnumBean mine = new EnumBean(v.ordinal(), v.name()); return mine; } @Override public Day unmarshal(EnumBean v) throws Exception { Day day = new Day(v.getOrdinal(),v.getName()); return day; } } ``` TEST CLIENT With the changes I suggested, I ran your service in WebLogic 12.1.1 and with the built in test client I got the following: Service Request ``` string 3 ``` Service Response ``` false ```
