Ok , I found a solution
I didn't remember what I did when I need to display a chart with T5
I create my own StreamResponse
look at it :
public class FileComponent {
@Inject
private ComponentResources _resources;
@SuppressWarnings("unused")
@Mixin
private RenderInformals _renderInformals;
@Environmental
private PageRenderSupport _support;
@BeginRender
public Boolean beginRender(MarkupWriter writer) {
String fileName = "helloWorld.txt"
Link link =
_resources.createActionLink(org.apache.tapestry.TapestryConstants.ACTION_EVENT,
false, fileName );
writer.element("a", "href", link.toURI());
writer.write(fileName);
writer.end();
return false ;
}
@OnEvent
public StreamResponse renderChart() throws IOException,
SprintNotFoundException {
return new FileStreamResponse(String) ;
}
private class FileStreamResponse implements StreamResponse {
public FileStreamResponse(String path) {
pathToYourFile = path ;
}
public String getContentType() {
//You should know the contentType of the file to be
downloaded
return "application/octet-stream";
}
public InputStream getStream() throws IOException {
FileInputStream stream = new FileInputStream(new
File(pathToYourFile)) ;
return stream;
}
public void prepareResponse(Response arg0) {
}
}
}
