Example to display image using Servlet

In this example, we are using FileInputStream class to read image and ServletOutputStream class for writing this image content as a response. To make the performance faster, we have used BufferedInputStream and BufferedOutputStream class.

You need to use the content type image/jpeg.

In this example, we are assuming that you have java.jpg image inside the c:test directory. You may change the location accordingly.

To create this application, we have created three files:

1. index.html
2. DisplayImage.java
3. web.xml

---

index.html

This file creates a link that invokes the servlet. The url-pattern of the servlet is servlet1.

---

DisplayImage.java

This servlet class reads the image from the mentioned directory and writes the content in the response object using ServletOutputStream and BufferedOutputStream classes.
