Please don't :-)
I don't mind private conversations but I honestly do not have time to
fix the code for reading the files into OutputStream, etc
Thank you

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 ?

But i would stream the bytes , not save the file on client .
Please some code or link of tutorial?
