Betreff: [castor-user] Unable to instantiate abstract class

 

Hi

 

I have a base element that is declated "abstract".  I am creating a instance of 
a concrete class that extends this abstract class. 

 

When I tried to read the XML. I get exception 

Unable to instantiate com.mae.frontend.command.BaseCmdRequestType; {file: [not 
available]; line: 10; column: 67}

 

Could you please help?

 

Thanks

 

-- Abstract class---

<xs:complexType name="BaseCmdRequestType" abstract="true">

  <xs:sequence>

     <xs:element ref="base:Parameters" minOccurs="0" maxOccurs="1"/> 

  </xs:sequence>

  <xs:attribute name="Name" type="xs:string" use="required" />

</xs:complexType>

 

-----Concrete class -----

 

<xs:complexType name="GetCommandStatusCmdType">

   <xs:complexContent>

       <xs:extension base="base:BaseCmdRequestType"/>
