Description

« Hide

Please see the XML from this URL
http://api.hi5.com/rest/feed/journal/1000

Enunciate publishes this as a JSON endopoint here:

http://api.hi5.com/json/feed/journal/1000

That url throws an error:
>
> java.lang.ClassCastException: org.codehaus.jettison.json.JSONArray
> cannot be cast to org.codehaus.jettison.json.JSONObject
>
org.codehaus.jettison.mapped.MappedXMLStreamWriter.writeAttribute(MappedXMLStreamWriter.java:93)
>
org.codehaus.jettison.mapped.MappedXMLStreamWriter.writeAttribute(MappedXMLStreamWriter.java:130)

org.codehaus.jettison.mapped.MappedXMLStreamWriter.writeAttribute(MappedXMLStreamWriter.java:134)

The badgerfish implementation doesn't have this problem. The value one does.

Can you try your code with the latests snapshot and see if it works ... http://snapshots.repository.codehaus.org/org/codehaus/jettison/jettison/1.0-RC3-SNAPSHOT/

If the problem still exists, can you produce valid test case or at least provide us with the info what do you use to create a feed (Rome?)

Still occurs with latest snapshot...

I'll attach some sample XML that dies...

Here's an xml file that causes the error.

The problem was related to writing attributes to array members. It's fixed now. I've tested it (additionally) by transforming the xml you provided to json with XStream copier. We'll make a release soon (today?) so I haven't made any snapshots.

Hi Vincent, I think it will be released today. Dan has some minor issue yesterday, so stay tuned

Hey Dejan, thanks for your quick response. However it would make it somewhat easier if I know when you will release a new version. It is just that I need to tell a customer when I will make a new release myself. Thanx
