Expected OData Entity, found EntitySet
I'm trying to use Olingo to connect to an Odata v4 service from Android.
I'm having a bit of trouble getting the filter to work
I've tested it with the Northwind sample and the URI that gets produce
works in a browser:
http://services.odata.org/Experimental/Northwind/Northwind.svc/Customers?%24filter=%28CustomerID+eq+%27ALFKI%27%29
I always get the following error:
=============================
java.lang.IllegalArgumentException:
org.apache.olingo.commons.api.serialization.ODataDeserializerException:
com.fasterxml.jackson.core.JsonParseException: Expected OData Entity, found
EntitySet
=============================
I'm using this code:
=============================
String serviceUrl = "
http://services.odata.org/Experimental/Northwind/Northwind.svc";
String entity = "Customers";
String filter = "CustomerID";
String id = "ALFKI";
try {
final ODataEntityRequest<ODataEntity> jsonReq =
client.getRetrieveRequestFactory().
getEntityRequest(client.newURIBuilder(serviceUrl).
appendEntitySetSegment(entity)
.filter(client.getFilterFactory().eq(filter,id)).build());
Log.v(TAG, "URI: " + jsonReq.getURI());
final ODataEntity spammer = jsonReq.execute().getBody(); //blows up here
=============================
how do I get the filter to work??
Thanks

Especially for documentation and support on the mailing list.
In addition we want to grow a friendly and helpful community for Olingo ;o)
Thanks to all and kind regards,

Re: Expected OData Entity, found EntitySet
Posted by Jonathan Peterson <jo...@gmail.com>.
Ah!
Thanks Fabio. That's what I was missing. I tried changing the ODataEntity
to ODataEntitySet but I didn't realize that I needed to change it to
ODataEntitySetRequest.
Also, it looks like I need to change that to .getEntitySetRequest as well.
My code now looks like this and works:
final ODataEntitySetRequest<ODataEntitySet> jsonReq =
client.getRetrieveRequestFactory().
getEntitySetRequest(client.newURIBuilder(serviceUrl).
appendEntitySetSegment(entity).
filter(client.getFilterFactory().eq(filter,id)).build());
final List<ODataEntity> results = jsonReq.execute().getBody().getEntities();
You guys need some documentation on the v4 stuff :)

Hi Jonathan, .filter() method return an entity set.
You should do something like as the following
String serviceUrl =
"http://services.odata.org/Experimental/Northwind/Northwind.svc";
String entity = "Customers";
String filter = "CustomerID";
String id = "ALFKI";
try {
final ODataEntitySetRequest<ODataEntitySet> jsonReq =
client.getRetrieveRequestFactory().
getEntityRequest(client.newURIBuilder(serviceUrl).
appendEntitySetSegment(entity).
filter(client.getFilterFactory().eq(filter,id)).build());
final ODataEntitySet feed = req.execute().getBody();
..... loop on entity set .....
}catch(....){
.....
}
Best regards,
F.

Re: Expected OData Entity, found EntitySet
Posted by Jonathan Peterson <jo...@gmail.com>.
I don't think I really need proxy classes for this project. In this case,
I'm going to be making the same request with a different ID to get one
property from the feed.
I looked at the Android tutorial already, however there's no simple "get
where this is that" sample (which is really weird)
I try the .filter(" CustomerID eq 'ALFKI' ") I still get the same error as
before. "Expected OData Entity, found EntitySet"

1, you should actually try to use the proxy classes. It will save you a lot
of pain.
2, I didnt use the RequestFactory that much, so i'm guessing right now. We
also had some issue with the filter factory, and ended up just to use some
strings. In your case
.filter(" CustomerID eq 'ALFKI' ")
Also have a look here

If you need help with generating the proxy classes, I can help you with that

1) nope I'm not using proxy classes.
2) I've added
FilterFactory filterFactory = client.getFilterFactory();
I've changed my filter to
.filter(filterFactory.eq(filterFactory.getArgFactory().property(filter),filterFactory.getArgFactory().property(id))).build());
and I get:
Could not find a property named 'ALFKI' on type 'NorthwindModel.Customer'
if I change "id" to
id = "%27ALFKI%27";
I'm back to the error message I was at before.
I'm only trying to retrieve one record here.

Hey Jonathan,
1.Are you using the proxy class? Those generated classes will save a lot of
time.
2 as for the uri builder, you can have a look in the framework unit test
to see how stuff works. Here is a test for filtering.
