RESTful with Castor. Collection result is fine, but single result is very poluted

[duduzerah]

I'm using the Spring Roo and generated an application. I want to have on it RESTful services. I don't know if i need to implement or if spring already do this for me.

I followed the links:
http://static.springsource.org/sprin...l/ch18s02.html

If i go to http://localhost:8080/geoLocationApp/address.xml the xml responsed is very good, with only "address" objects inside the list. That's ok.

But if I want to get only a object, I do the url:
http://localhost:8080/geoLocationApp/address/1.xml

The result is very big, with a lot of objects I don't want. I don't know if I need to customize my own marshaller or if the CastorMarshaller of spring 3 would do that.

Here is the example of the result of the URL http://localhost:8080/geoLocationApp/address.xml;

<array-list>
−
<Address xsi:type="Address">
<ident>1</ident>
<descricao>Evil address.</descricao>
<version>0</version>
</Address>
−
<Address xsi:type="Address">
<ident>2</ident>
<descricao>Rua Barroso.</descricao>
<version>0</version>
</Address>
</array-list>

Here is the example of the url http://localhost:8080/geoLocationApp/address/2.xml. It's Very poluted:

Hello,

Did you find any solution for this? I am facing the same problem.

Thanks,
Shweta

[duduzerah]

I think so...
I dont remember very well.. sorry.

But, I think I've tried to customize mapping.xml file of castor.

[shweta.deshpande]

Thanks for your reply. Turned out I had the mapping.xml file configured correctly, but the mapping that I used in my code was incorrect. I was not supplying the correct class type to the object being marshalled. I changed that and it works perfectly now .
