>             Project: CXF
>          Issue Type: Improvement
>          Components: JAX-RS
>    Affects Versions: 2.4

> CXF's JAX-RS implementation can presently read from but not write to data sources (javax.activation.DataSource).  Provide an ability to write to data sources so we can code this way:
> @Produces("image/jpg")
> @GET
> public DataSource getImageRep() {
>     URL jpgURL = this.getClass().getResource("myimage.jpg");
>     return new FileDataSource(jpgURL.getFile());     
> } 
> instead of something like this:
> @Produces("image/jpg")
> @GET
> public InputStream getImageRep() {
>    FileInputStream fis = null;
>    try {
>       URL jpgURL = this.getClass().getResource("myimage.jpg");
>       fis = new FileInputStream(new File(jpgURL.getPath()));
>    } catch (IOException e) {
>       System.out.println("Couldn't find file!");
>    }
>    return fis;
> }
