You code is more or less correct, get the file bytes written to
OutputStream which is available to StreamingOutput implementations,
and set the actual type directly on Response object

please Sergey you can complete my code ???? read at 1) and 2) and 3)

1) i not have not declared any @Produce at retod that Stream the image ,
because i would set into the code because it can be a image/jpg, image/bmp,
image/gif, ,image.png , and many other type .
The content typoe it is saved into the db when i save the image with JPA
into DB .
2) how i write the bytes into resposne?
3) how i set the contenttype that i get from entityJPA?
package myrest.mauro;
import java.io.*;
import javax.inject.Inject;
import javax.ws.rs.Path;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.StreamingOutput;
import myrest.mauro.ImageEntityJPA;
import myrest.mauro.MyDAO;
/**
*
* @author utente_javaee7
*/
@Path("/imagefromdb")
public class SearchImageFromDB {
@Inject MyDAO myDAO;
@GET
// 1) i not have declared any @Produces
@Path("/{id}")
public Response hello(@PathParam("Id") long Id) {
ImageEntityJPA myimage =myDAO.getImageEntityJPAFromId(Long
id)
byte[] bytesfromdb= myimage.getBytesimage();
String contenttype= myimage.getContenttype();
ByteArrayOutputStream baos= new ByteArrayOutputStream (bytesfromdb);
StreamingOutput stream = new StreamingOutput() {
@Override
public void write(OutputStream os) throws IOException,
WebApplicationException {
// 2) how write the bytes of image??????????
}
};
// 3) how set the content type that i get form entityJPA?
return Response.ok(stream).build();
}
}

Hi
Have you resource method returning the implementation of
https://jax-rs-spec.java.net/nonav/2.0/apidocs/javax/ws/rs/core/StreamingOutput.html
CXF 3.0.0 (released in the next couple of weeks) has introduced
https://git-wip-us.apache.org/repos/asf?p=cxf.git;a=blob;f=rt/frontend/jaxrs/src/main/java/org/apache/cxf/jaxrs/ext/StreamingResponse.java,
a typed analog of StreamingOutput, I will document it shortly
But using StreamingOutout for returning the file should work perfectly
well
Cheers, Sergey

Hi all. i would get a image from a db .
I get the bytes[] of image and the content.type saved into db with JPA

But next how i can stream into the Response for show into a web page ?
i have found example for save the file with saveas ...
But i would stream the bytes , not save the file on client .
Please some code or link of tutorial?
