[castor-dev] Castor XML - encountering a problem when umarshalling a collection

[Anand Krishnan]

Title: Message

I am encountering a problem when unmarshalling a collection. Specifically I get a collection object populated with one(1) not null, but otherwise empty object/element instead of a fully populated collection with objects set with their associated attribute/properties.

 

I am using Castor XML v.0.9.5.3 and JDK v.1.4.2_03.

 

The following are the relevant pieces (I think):

Here is the marshalled xml that I am now trying to umarshal:

 

-------------------------------------------------------------------

<YMIA:Product Id="999" GroupId="17" xmlns:YMIA="http://www.example.com/YMIA">
    <YMIA:Name>CVP-309GP</YMIA:Name>
    <YMIA:FilesystemName>cvp-309gp</YMIA:FilesystemName>
    <YMIA:DisplayName>CVP-309GP</YMIA:DisplayName>
    <YMIA:Descriptions>
        <YMIA:Description Id="983" DescriptionTypeId="4" ProductId="999">
            <YMIA:DescriptionText>An advanced full-sized...</YMIA:DescriptionText>
        </YMIA:Description>
        <YMIA:Description Id="982" DescriptionTypeId="3" ProductId="999">
            <YMIA:DescriptionText>The CVP-309GP is an...</YMIA:DescriptionText>
        </YMIA:Description>
        <YMIA:Description Id="981" DescriptionTypeId="2" ProductId="999">
            <YMIA:DescriptionText>The CVP-309GP is...</YMIA:DescriptionText>
        </YMIA:Description>
    </YMIA:Descriptions>
</YMIA:Product>

-------------------------------------------------------------------

 

Here is Castor mapping xml:

 

<?xml version="1.0"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Object Mapping DTD Version 1.0//EN"
                         "http://castor.exolab.org/mapping.dtd">

 

<mapping>
    <description>Product mapping</description>

 

    <class name="com.my.pkg.Product">
        <map-to xml="Product" ns-prefix="YMIA" ns-uri="http://www.example.com/YMIA"/>

 

        <field name="id" type="java.lang.Integer">
            <bind-xml name="Id" node="attribute"/>
        </field>

 

        <field name="name" type="java.lang.String">
            <bind-xml name="Name" node="element"/>
        </field>

 

        <field name="filesystemName" type="java.lang.String">
            <bind-xml name="FilesystemName" node="element"/>
        </field>

 

        <field name="descriptions" type="com.my.pkg.Description" collection="array">
            <bind-xml name="Description" location="Descriptions" node="element"/>
        </field>

 

    </class>

 

    <class name="com.my.pkg.Description">
        <map-to xml="Descriptions" ns-prefix="YMIA" ns-uri="http://www.example.com/YMIA"/>

 

        <field name="id" type="java.lang.Integer">
            <bind-xml name="Id" node="attribute"/>
        </field>

 

        <field name="descriptionTypeId" type="java.lang.Integer">
            <bind-xml name="DescriptionTypeId" node="attribute"/>
        </field>

 

        <field name="productId" type="java.lang.Integer">
            <bind-xml name="ProductId" node="attribute"/>
        </field>

 

        <field name="descriptionText" type="java.lang.String">
            <bind-xml name="DescriptionText" node="element"/>
        </field>
    </class>

 

</mapping>

-------------------------------------------------------------------

 

The output:

 

product=
    id=999
    name=CVP-309GP
    fileSystemName=cvp-309gp
    displayName=CVP-309GP
    descriptions=[Lcom.my.pkg.Description;@e61a35
        description=
            id=null
            productId=null
            descriptionTypeId=null
            descriptionText=

-------------------------------------------------------------------

 

 

Additionally I have set the following umarshalling instructions:

    Unmarshaller unmar = new Unmarshaller(mapping);
    unmar.setIgnoreExtraElements(true);
    unmar.setIgnoreExtraAttributes(true);

I think the problem is in the mapping configuration, but I have not been able to figure it out.

 

Any help would be appreciated. Thanks.
