Glen Mazza reopened CXF-3380:
-----------------------------
Hi, this sample is still indicating a problem (perhaps one further down after
the latest change made):
https://github.com/gmazza/jersey-samples-on-cxf/tree/master/simple-servlet
For this class within it:
https://github.com/gmazza/jersey-samples-on-cxf/blob/master/simple-servlet/src/main/java/com/sun/jersey/samples/servlet/resources/ResourceBean3.java
The traditional way as described in this JIRA (lines 153-164) works but the
DataSoure way (143-151) doesn't.
Steps to replicate:
1. Check out simple-servlet:
git clone https://github.com/gmazza/jersey-samples-on-cxf.git
(move to simple-servlet folder).
2. Run "mvn clean install" on it.
3. Run "mvn jetty:run" and go to this page in a browser:
http://localhost:8080/SimpleServlet/resources/start
4. From the top, select "Resource 3", press the "Test Resource" button, leave
Fred & Barney as-is, choose "Selection Method" of "Query Parameter" and MIME
type of image/jpg.
5. Select the lower "Test Resource" button. You'll see the Oracle Duke
logo/picture. Everything good.
6. In class ResourceBean3 listed above, comment out the "public InputStream
getImageRep()" method and uncomment the "public DataSource getImageRep()"
method; repeat steps 2-5 above. This time, though, no picture is returned and
server reports back "WARNING: No message body writer has been found for
response class FileDataSource."
> JAX-RS: Support writing to DataSources
> --------------------------------------
>
> Key: CXF-3380
> URL: https://issues.apache.org/jira/browse/CXF-3380
> Project: CXF
> Issue Type: Improvement
> Components: JAX-RS
> Reporter: Glen Mazza
> Assignee: Sergey Beryozkin
> Fix For: 2.3.8, 2.4.5, 2.5.1
>
>
> 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;
> }
