Hi Nicoktay,
Unfortunately the documentation is a bit unclear of how to make the calls
and what it expects.
There are two ways of creating assets through the REST interface both which
produces Atom Entries as responses. Ideally we should be able to return
other responses than Atom Entries.
The way you are trying to create the asset is by posting a stream, this also
produces an Atom Entry as response.
When posting as a stream you also need to include a slug header specifying
the asset name. Based on the extension we will determine what type of asset
it is.
Something like this:
Response response=
client.path("guvnor-5.4.0.Final-jboss-as-7.0/rest/packages/mortgages/assets")
.accept(MediaType.APPLICATION_ATOM_XML_TYPE)
.type(MediaType.APPLICATION_OCTET_STREAM_TYPE)
.header("slug", "myAssetName.drl")
.post(source);
