[Axis2] Axis2 and Enum type
Hello there,
I created a simple function that returns an object type of enum.
It is very simple function:
public static Gender getGender() {
return Gender.MALE;
}
but when I opened the page from a browser
http://localhost:8080/OpenApi/services/TestApi10/getGender
it generates an error like
<soapenv:Reason>
<soapenv:Text xml:lang="en-US">
java.lang.RuntimeException: org.apache.axis2.AxisFault: Mapping qname not fond for the package: org.apache.catalina.loader
</soapenv:Text>
</soapenv:Reason>
If I return any other objects, it works fine.
Am I not supposed to Enum type?
I think this is an error in Axis2.
By the way, I would not like to use Type-safe enum.
It has its own problem.
I have attached a source code and services.xml (TestApi.xml) and wsdl (TestApi10.xml - created by Axis2 on the fly).
By the way, if I create a client using WSDL2Java
wsdl2java.bat -or -g -Eofv -uw -u -uri http://localhost:8080/OpenApi/services/UserApi10?wsdl
I get a warning like this:
[WARN] Type {http://www.w3.org/2001/XMLSchema}Enum missing!
How do I get rid of this?
Also WSDL2Java doesn't create a enum type for Gender. Rather it is a regular class.
Which I have to use it like
Gender g = new Gender();
g.getFEMALE();
This didn't make a sense to me.
As a comparison, .NET create an enum type correctly.
In WSDL that .NET create, it is a just simpleType with restrictions.
I don't know if that caused the problem or not.
I would appreciate if you could give any help on this.
Thank you,
- Leon

Posted by Leon Hwang <hw...@mystrands.com>.
They said the current Axis2 is based on Java 1.4 which doesn't have the enum type definition.
I was told that this will be fixed in the next release (I am not sure if that was an official answer or not).
For creating WSDL, look at the code (WSDLDataLocator.java) in Axis2 source.
Here is what I do.
Instead of inventing WSDL creator, create your own data locator "extended" from WSDLDataLocator.
In outputInlineForm, get the result (OMElemet) from the parent and make changes there.
protected Data[] outputInlineForm(MessageContext msgContext, ServiceData[] dataList)
throws DataRetrievalException {
Data[] result = super.outputInlineForm(msgContext, dataList);
if (null != result && null != result[0]) {
OMElement wsdlElement = (OMElement)result[0].getData();
this.generateCustomWSDL(wsdlElement); // call your own function
result[0] = new Data(wsdlElement, null);
}
return result;
}
Then, add datalocator in service.xml
<service name="api">
<description>Some API</description>
<messageReceivers>
<messageReceiver
mep="http://www.w3.org/2004/08/wsdl/in-only"
class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</messageReceivers>
<parameter name="ServiceClass" locked="false">
YOUR_SERVICE_CLASS
</parameter>
<dataLocator>
<dialectLocator dialect="http://schemas.xmlsoap.org/wsdl/"
class="YOUR_DATA_LOCATOR_CLASS" />
</dataLocator>
</service>
Hope this helps.

I don't quit get the response. I don't generate the wsdl myself. Axis2
servlet does that I suppose.
In my method I should return int instead?

Re: [Axis2] Axis2 and Enum type
Posted by robert lazarski <ro...@gmail.com>.
This is an old problem. Until Axis2 gets code to support java 5 enums,
I just do a
simple conversion. With this example in the wsdl:
<element minOccurs="1" maxOccurs="1" nillable="true"
name="TipoMibEnum" type="xsd:int"/>
You'd get that value in the Service with the idea of converting it to this:
public enum TipoMib implements Serializable{
MIB2,
MIB_GERENCIA,
MIB_ESPECIFICA;
}
I do the conversion as:
private static TipoMib getTipoMib(Integer ordinal) {
if (TipoMib.MIB2.ordinal() == ordinal) {
return TipoMib.MIB2;
} else if (TipoMib.MIB_ESPECIFICA.ordinal() == ordinal) {
return TipoMib.MIB_ESPECIFICA;
} else if (TipoMib.MIB_GERENCIA.ordinal() == ordinal) {
return TipoMib.MIB_GERENCIA;
} else
return null;
}
To convert the other way I do tipoMib.ordinal() - see the javadoc of
Enum about ordinal() .
HTH,
Robert

You can communicate this via the WSDL for your service. The schema used to
define the input elements for your operations can use <xs:enumerations>. Any
client having this WSDL knows what the operation expects.

Wow...
Thank you, Keith.
Then, I guess, returning enum type won't do any good. (like I can...)
What does people do?
Is there any alternative?
Only way I can think of is to return a primitive type or String representation of the enum value,
then communicate with developers wring client, "You have to use this EXACT string".
Keith, do you happen to know when the enum feature will be supported by Axis2?
Thank you, again.

Axis2 is JDK 1.4 compatible. Hence it does not use JDK 1.5 features. This is
the reason you see code like the following.
Gender g = new Gender();
g.getFEMALE();
Thanks,
Keith.
