Hello,
I am trying to map an xml data file into java objects and it seems as if the
nested collections are not being populated at all.
Here is a snippet of the mapping file (class names truncated for brevity):
<mapping>
<class name="Data2">
<field name="type" type="string">
<bind-xml name="type" node="attribute"/>
</field>
<field name="tuples" type="DataTuple" collection="arraylist">
<bind-xml name="tuple" location="tuples"/>
</field>
<field name="dataSource" type="DataSource">
<bind-xml name="dataSource"/>
</field>
</class>
<class name="DataTuple">
<field name="name" type="string">
<bind-xml name="name" node="attribute"/>
</field>
<field name="type" type="string">
<bind-xml name="type" node="attribute"/>
</field>
</class>
<class name="DataSource">
<field name="user" type="string">
<bind-xml name="user" node="attribute"/>
</field>
<field name="pass" type="string">
<bind-xml name="pass" node="attribute"/>
</field>
<field name="connectionUrl" type="string">
<bind-xml name="connectionUrl" node="element"/>
</field>
</class>
</mapping>
Here is a snippet of the data file:
<data>
<dataObject type="temperature">
<tuples>
<tuple name="temperature" type="int" />
</tuples>
<dataSource user="user" pass="pass">
<conectionUrl>jdbc:postgresql://localhost/db</conectionUrl>
</dataSource>
</dataObject>
<dataObject type="power">
<tuples>
<tuple name="power" type="int" />
</tuples>
<dataSource user="user" pass="pass">
<conectionUrl>jdbc:postgresql://localhost/db</conectionUrl>
</dataSource>
</dataObject>
</data>
The output shows that the object has not been initialised properly i.e. the
arraylist is empty
WMData2 [type=temperature, ArrayList(size=0) [], wmDataSource=null]
The object DOES have the type correctly initialised.
I have tried tweaking the mapping file with no success and have re-read the
instructions(!)
What am I missing here, please? Any more things I can try?
Cheerio,
Nic Hemley
