[rules-dev] rest api - new asset file extension in guvnor

[Tihomir Surdilovic]

Hi guys, I have a question about creating new assets in Guvnor via rest 
api, specifically on how to set the file extension of the new asset.
My code is simple:

URL createURL = new URL(packageAssetsURL); // example url: 
http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/MyImage
HttpURLConnection createConnection = (HttpURLConnection) 
createURL.openConnection();
applyAuth(profile, createConnection);
createConnection.setRequestMethod("POST");
createConnection.setRequestProperty("Content-Type", 
"application/octet-stream");
createConnection.setRequestProperty("Accept", "application/atom+xml");
createConnection.setRequestProperty("Slug", assetName); // assetName is 
for example MyImage
createConnection.setDoOutput(true);

// apache batik streams the png image data
PNGTranscoder t = new PNGTranscoder();
TranscoderInput input = new TranscoderInput(new StringReader(svg));
TranscoderOutput output = new 
TranscoderOutput(createConnection.getOutputStream());
t.transcode(input, output);

The MyImage asset gets created fine in Guvnor under defaultPackage, but 
the file extension is .txt and not .png
If I specify the file extension in the "Slug" request property the file 
created is for example MyImage.png.txt.

Is there any request property or anything else I need to set on the 
connection to tell guvnor the actual file extension of the new asset??

Any input is much welcome.

Thanks.
