> I've a WebService whose WSDL is View.wsdl. The result returned adheres to the View.xsd (which is flattened into the View.wsdl for ease of use). The WebService returns "FlexElementResult__Type" which is defined as given below. On the client side, I use Axis 1.2.1 (I tried 1.2 as well as 1.1) with proxies generated using WSDL2Java tool. 
> <xs:complexType name="FlexElementResult__Type">
>   <xs:sequence>
>     <xs:element name="Value" type="Value_Type" nillable="true"/>
>   </xs:sequence>
>   <xs:attribute name="Name" type="xs:string" use="required"/>
> </xs:complexType>
> <xs:simpleType name="Value_Type">
>   <xs:union memberTypes="xs:boolean xs:date xs:string xs:decimal xs:gYearMonth xs:int xs:integer xs:long xs:float LoanType__Type"/>
> </xs:simpleType>
> The WebService returns the following payload. I've a small PHP file setup on my hosting site that returns this following response for testing purposes at http://72.3.135.4/EMCAxisBug.php 
> <fnf:ViewReadResponse xmlns:fnf="http://example.test.com/services/View/1.01">
>   <Element Name="BorrowerName" xmlns:fnf1="http://example.test.com/services">
>     <Value xsi:type="xs:string">TEST,NAME</Value>
>   </Element>
>   <Element Name="OriginalMortgageAmount" xmlns:fnf1="http://example.test.com/services">
>     <Value xsi:type="xs:decimal">99888.00</Value>
>   </Element>
>   <Element Name="LoanType" xmlns:fnf1="http://example.test.com/services">
>     <Value xsi:type="fnf:LoanType__Type">ConventionalWithoutPMI</Value>
>   </Element>
> </fnf:ViewReadResponse>
> This XML reponse is valid per schema View.xsd.
> But, when I use my test case with the generated axis client proxy, I get the following exception:
> - Could not convert java.lang.String to bean field 'value', type com.test.example.services.View._1_01.Value_Type
> - Exception:
> java.lang.IllegalArgumentException: argument type mismatch

> I don't see anything wrong with the response XML. I've a build.xml attached that generate the proxy classes and runs my test against my hosted hard-coded webservice php file. I also attached a hard-coded JSP webserivce simulator EMCAxisBug.jsp for your local testing.
> I went through the mailing archives and googled for this, but nothing really solved this problem and it looks to me like a bug in the deseriazation and handling of union types.
> I am attaching the eclipse project am using along with all the sample response, wsdl, xsd etc etc.
> Please let me know if you need anything else.
> Thanks
