Hello,
I'm trying to map the contents of an xml file to a HashMap. The XML-file looks
like:
<seti>
<chain index="CHN001" shortname="A1">
<name>A1</name>
</chain>
<chain index="CHN002" shortname="A2">
<name>A2</name>
</chain>
<chain index="CHN003" shortname="RpConf">
<name>RC</name>
</chain>
</seti>
and the java class is:
public class Seti implements java.io.Serializable {
private HashMap chainList;
public Seti()
{
super();
chainList = new HashMap();
}
public HashMap getChainList() {
return chainList;
}
public void setChainList( HashMap chainList ) {
this.chainList = chainList;
}
}
It works if I use the attribute "index" as key and the child-element <name> as
value of the Hash. The mapping looks then like this:
<?xml version="1.0" encoding="UTF-8"?>
<mapping xmlns="http://castor.exolab.org/";
xmlns:cst="http://castor.exolab.org/";>
<description>Castor generated mapping file</description>
<class cst:name="com.infineon.pd.pt.tpec.setixml.Seti">
<description>
Default mapping for class
</description>
<map-to cst:xml="seti"/>
<field cst:name="chainList" cst:type="java.util.HashMap"
cst:collection="map">
<bind-xml name="chain">
<class name="org.exolab.castor.mapping.MapItem">
<field name="key"
type="java.lang.String">
<bind-xml name="index"
node="attribute" />
</field>
<field name="value"
type="java.lang.String">
<bind-xml name="name"
node="element" />
</field>
</class>
</bind-xml>
</field>
</class>
</mapping>
But what I really want is to have the chain class as the value of my hash. I
tried to adapt the mapping file to achieve this:
<?xml version="1.0" encoding="UTF-8"?>
<mapping xmlns="http://castor.exolab.org/";
xmlns:cst="http://castor.exolab.org/";>
<description>Castor generated mapping file</description>
<class cst:name="com.infineon.pd.pt.tpec.setixml.Seti">
<description>
Default mapping for class
</description>
<map-to cst:xml="seti"/>
<field cst:name="chainList" cst:type="java.util.HashMap"
cst:collection="map">
<bind-xml name="chain">
<class name="org.exolab.castor.mapping.MapItem">
<field name="key"
type="java.lang.String">
<bind-xml name="index"
node="attribute" />
</field>
<field name="value"
type="com.infineon.pd.pt.tpec.setixml.Chain">
<bind-xml name="chain"
node="element" />
</field>
</class>
</bind-xml>
</field>
</class>
<class cst:name="com.infineon.pd.pt.tpec.setixml.Chain">
<description>
Default mapping for class
com.infineon.pd.pt.tpec.setixml.Chain
</description>
<map-to cst:xml="chain"/>
<field cst:name="index" cst:type="java.lang.String"
cst:required="true">
<bind-xml name="index" node="attribute" />
</field>
<field cst:name="shortname" cst:type="java.lang.String"
cst:required="true">
<bind-xml name="shortname" node="attribute" />
</field>
<field cst:name="name" cst:type="java.lang.String"
cst:required="true">
<bind-xml name="name" node="element" />
</field>
</class>
</mapping>
But this fails with the following error message:
unable to find FieldDescriptor for 'name' in ClassDescriptor of map-item{file:
[not available]; line: 5; column: 9}
Does this mean I can't put the <chain> element as value into my hash? Does
there exist a workaround?
Thanks,
Jörg Werner
