Hello,
I've just had a look in the code. I'm using @Get("txt") on toPlainText()
and @Get("xml") on toXml().
In ServerResource.getAvailableVariants(Method), when it goes through:
annoVariants = cs.getVariants(annotationInfo
.getJavaReturnType(), new Variant(
(MediaType) metadata));
the values are:
- annotationInfo.getJavaReturnType() -> Representation
- metadata -> MediaType.PLAIN_TEXT
Then, in ConverterService.getVariants,
helperVariants = ch.getVariants(sourceClass);
helperVariants is a list that contains only the octet-stream media type.
What I guess from this is that the Representation type is considered to
be able to be converted only to an octet-stream and the text/plain media
type is never going to be considered in the rest of
ServerResource.getAvailableVariants.
This seems a bit surprising.
ServerResource.java doesn't seem to be formatted properly in revision
5060, by the way.
Best wishes,
Bruno.
