Re: [castor-dev] Using the reference attribute for xml mapping

[Arvin, Shawn POP/Exch)]

I was able to come up with a work around by altering my object model. However I still like to know the castor's solution for this since this must be a very common occurrence in java. If anyone has any insight into this please let me know. Thanks for your help Jerome.   Shawn   -----Original Message----- From: Pastre Jerôme [mailto:[EMAIL PROTECTED] Sent: Thursday, April 15, 2004 9:42 AM To: [EMAIL PROTECTED] Subject: Re: [castor-dev] Using the reference attribute for xml mapping   I don't know the answer of your last question.   Maybe Keith Visco  could help you more ......   --Jerome   -----Message d'origine----- De : Arvin, Shawn POP/Exch) [mailto:[EMAIL PROTECTED] Envoyé : jeudi 15 avril 2004 15:06 À : '[EMAIL PROTECTED]' Objet : Re: [castor-dev] Using the reference attribute for xml mapping Hi Jerome, Thank you for your response. I was able to get it working as you describe, my problem was that I missed the part that the node had to be set to attribute. But not I am facing a different problem. What happens when the field that is doing the referencing is actually referencing an interface, where you could have instances of different classes. What I am seeing here is that the unmarshalling to xml looks ok but I can't go back from xml to java objects. Here is an example of the way I defined my mapping:       <class name=" ComplexType"  identity="qualifiedName" >         <field name="qualifiedName" type="string"/>     </class>       <class name=" PrimitiveTypeEnum" identity="name" verify-constructable="false">         <field name="name" type="string"/>     </class>       <class name=" Attribute">         <field name="type" type="TypeDescriptor" >             <bind-xml name="attr_type" node="attribute" reference="true"/>         </field>     </class>     Both ComplexType and PrimitiveTypeEnum classes implement the interface TypeDescriptor. The Attribute Class has an attribute "type" of type TypeDescriptor. I don't see how castor can determine from the xml output which class to instantiate since the only thing that it outputs for the attr_type is the value and no class info.   Thanks   Shawn -----Original Message----- From: Pastre Jerôme [mailto:[EMAIL PROTECTED] Sent: Thursday, April 15, 2004 6:13 AM To: [EMAIL PROTECTED] Subject: Re: [castor-dev] Using the reference attribute for xml mapping   Hi Shawn,   This an example of mapping file :   <class name="pack3.lE"   identity="leOid">    <field name="leOid" >            <bind-xml node="attribute"/>    </field>         </class>          <class name="pack3.aG"  >        <field name="refLe" type="pack3.lE" >                 <bind-xml reference="true" node="attribute"/>        </field>     </class>       --Jerome -----M essage d'origine----- De : Arvin, Shawn POP/Exch) [mailto:[EMAIL PROTECTED] Envoyé : mercredi 14 avril 2004 21:32 À : '[EMAIL PROTECTED]' Objet : [castor-dev] Using the reference attribute for xml mapping   Hi, I am using the xml mapping and trying to figure out how the "identity" and "reference" attributes are supposed to be used in a mapping file?   Thanks,   Shawn
