[infinispan-issues] [JBoss JIRA] (ISPN-3770) Incorrect Content-Type header when putting object via REST and get with different Accept

[Martin Gencur (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-3770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12927365#comment-12927365 ] 

Martin Gencur commented on ISPN-3770:
-------------------------------------

Jiri, I looked at the implementation and it works as follows:
When an object is stored via REST with Content-Type: application/x-java-serializable-object , it does not matter what Content-Type you ask for when retrieving the data with REST. It will always return the same Content-Type the data was stored with. 

Accepting JSON or XML should work only in compatibility mode when the data was stored in library mode or via HotRod. Also, if you store plain byte array via library mode or HotRod, you cannot specify Accept header when later retrieving the data via REST. The content-type of the returned entry will be always APPLICATION_OCTET_STREAM. You'd have to store POJO in order to be able to get back json/xml later via REST.

> When putting serialized object via REST post and then getting it back with different Accept header (for example application/json), the retrieved data has still the "creation-time" Content-Type and data doesn't change in any way.
> I would expect retrieving nice json structure for instace.
> Code snippet:
> {code}
> public void testCustomObjectGetAcceptJSONAndXML() throws Exception{
>         String fullPathKeyA = fullPathKey(KEY_A);
>         TestSerializable object = new TestSerializable("CONTENT");
>         ByteArrayOutputStream bout = new ByteArrayOutputStream();
>         ObjectOutputStream oo = new ObjectOutputStream(bout);
>         oo.writeObject(object);
>         oo.flush();
>         oo.close();
>         byte[] byteData = bout.toByteArray();
>         post(fullPathKeyA, byteData, "application/x-java-serialized-object");
>         HttpResponse getJson = get(fullPathKeyA, null, HttpServletResponse.SC_OK, true, "Accept", "application/json");
>         assertTrue(getJson.getHeaders("Content-type")[0].getValue().contains("application/json")); //this assertion fails
>         HttpResponse getXml = get(fullPathKeyA, null, HttpServletResponse.SC_OK, true, "Accept", "application/xml");
>         assertTrue(getXml.getHeaders("Content-type")[0].getValue().contains("application/xml")); //this assertion fails
>     }  
> {code}
