Hi,
I'm new to JiBX and I'm having problems binding a list of list of
objects. Here is what I got:
java.util.ArrayList polygon
where polygon contains ArrayList objects which contains Points objects.
I tried the following bindings:
1)
<mapping name="polygon"
class="com.webraska.vulcan.pack.search.geometry.Polygon">
<collection name="boundaries" field="boundaries">
<structure name="boundary">
<collection
item-type="com.webraska.vulcan.pack.search.geometry.Point"/>
</structure>
</collection>
</mapping>
Points is also defined in the bindings:
<mapping name="point"
class="com.webraska.vulcan.pack.search.geometry.Point">
<value name="id" get-method="getId" set-method="setId"/>
<value name="longitude" get-method="getLongitude"
set-method="setLongitude"/>
<value name="latitude" get-method="getLatitude"
set-method="setLatitude"/>
</mapping>
Here I have a compilation error :
[jibx] org.jibx.runtime.JiBXException: Unknown collection type with no
add or store method defined at tag "collection".
The tag collection the compiler talks about is the second one.
2)
I also tried this binding, since JiBX knows the binding of an ArrayList.
It was my assumption that in boudaries, JiBX found an ArrayList -> he
knows the binfind. Then inside each arrayList he finds an object he
knows the binding of (Points) so it was OK.
<mapping name="polygon"
class="com.webraska.vulcan.pack.search.geometry.Polygon">
<collection field="boundaries" item-type="java.util.ArrayList"/>
</mapping>
But I have this error at run time:
org.jibx.runtime.JiBXException: Collection item of type
java.util.ArrayList has no binding defined
at JiBX_MungeAdapter.JiBX_etc__marshal_1_1()
at
com.webraska.vulcan.pack.search.geometry.Polygon.JiBX_etc__marshal_1_0(P
olygon.java)
...
3)
Also tried this one:
<collection name="boundaries" field="boundaries"
item-type="java.util.ArrayList">
<structure name="boundary">
<collection
item-type="com.webraska.vulcan.pack.search.geometry.Point"/>
</structure>
</collection>
But I have a compilation error telling me that JiBX is expecting the
collection tag to end immediately if it contains the attribute
'item-type'
If someone knows how to deals with nested lists it will help me a lot.
Thanks
Gilles
