Dear Castor XML users,
I'm trying to unmarshall the following XML which at some point should result
in an ArrayList containing a Double(1.5), a String("Text") and another object
called Boundaries.
<?xml version="1.0" encoding="UTF-8"?>
<table ...>
<map xsi:type="tableType" name="exampleTable">
<column name="ExampleColumn">
<!-- Double -->
<value xsi:type="java:java.lang.Double">1.5</value>
<!-- String -->
<value xsi:type="java:java.lang.String">Text</value>
<!-- Boundaries object -->
<value xsi:type="boundariesType" lowerboundary-inclusive="0"
upperboundary-exclusive="15"/>
</column>
</map>
</table>
The mapping file looks like this.
<class name="....Table">
<map-to xml="tableType"/>
...
<!-- Put columns in a Map with key=columnName and value=ArrayList of
column values -->
<field name="columns" collection="map">
<bind-xml name="table:column">
<class name="org.exolab.castor.mapping.MapItem">
<field name="key" type="string">
<bind-xml name="name" node="attribute"/>
</field>
<!--
=============================================================
type="java.lang.Object" is needed to get this to work. Why?
==============================================================
-->
<field name="value" type="java.lang.Object"
collection="arraylist">
<bind-xml name="table:value" node="element"/>
</field>
</class>
</bind-xml>
</field>
</class>
<class name="my.package.Boundaries">
<map-to xml="boundariesType"/>
...
</class>
I CAN get this to unmarshall successfully but I need to specifiy the arraylist
field type as "java.lang.Object"!!!
I don't like that, I would rather:
1) ...set the type to "double" or "java.lang.Double" so I can skip the
xsi:type="java:java.lang.Double" in my XML. However, that gives me an "unable
to resolve reference: [EMAIL PROTECTED]" when reading
the boundariesType.
2) ...remove the type="java.lang.Object" completely, but that gives me a
NullPointerException in
org.exolab.castor.xml.util.XMLFieldDescriptorImpl.hashCode().
What's causing this? Are there any ways to set the (default) type to "double"?
Regards,
Martijn.
