            hi nbelaevski,

            xhtml

            <a4j:mediaOutput element="object" session="true" createContent="#{SampleManager.play}" value="#{Sample.sample.file}"
            cacheable="false" width="300"/>


            SampleManager backing bean
            public synchronized void play(OutputStream stream, Object object) throws IOException {
             stream.write((byte[])object);
             }


            Sample persistence (called from value="#{Sample.sample.file}")
            public byte[] getFile() {
             return file;
             }


            im not sure if im doing the right thing with this " value="#{Sample.sample.file}" " on the a4j:mediaoutput tag. And the play method from my backing bean never been called.

            thanks for reply.

              forget the last codes.

              Now it works fine in Firefox, but in IE never calls the play method.

              xhtml:

              <a4j:mediaOutput session="true" element="object" mimeType="audio/x-wav" createContent="#{SampleManager.play}" value="#{SampleManager.file.name}" cacheable="false" width="300"/>
              
              

              i think the "value" isn't necesary in my case...

              SampleManager:
              public synchronized void play (OutputStream stream, Object object) throws IOException {
               SessionLogger.getInstance().STDLOG("SampleManager.paint()");
               stream.write(this.getFile().getData());
               stream.flush();
               stream.close();
               }
              
              


              this.getFile().getData() returns the .wav in byte[].
