hello
I found this example from net and tried :
<a4j:mediaOutput id="telephone" element="img" cacheable="false" session="true"
mimeType="image/png"
createContent="#{imagePainter.drawImage}" >
</a4j:mediaOutput>
and backing bean
package net.javabeat.articles.ajax4jsf.introduction;
import java.io.*;
public class ImagePainter {
private String fileName = "dkonak_toygar.png";
public void drawImage(OutputStream output, Object object)
throws IOException {
System.out.println("doÄŸa");
File file = new File(fileName);
byte byteArray[] = new byte[1000];
FileInputStream inputStream = new FileInputStream(file);
while (true) {
try {
System.out.println(file.getAbsoluteFile());
int bytesRead = inputStream.read(byteArray);
output.write(byteArray, 0, bytesRead);
} finally {
if (inputStream != null) {
inputStream.close();
}
}
}
}
}
But I always got this message although I checked the image file and the java bean.
java.io.IOException: Bad file descriptor
what can I do ?
regards
