problem in pointing to a servlet from image tag.

[gayathri murugesan]

 
response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
          FileInputStream fis = null;
        try {
            
                Class.forName("oracle.jdbc.OracleDriver");
                Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@pc009384:1521:pc009384", "aj033", "AJ033");
                 PreparedStatement pst1 = conn.prepareStatement("select pic from b where id=?");
                ResultSet rs1= pst1.executeQuery();
               while(rs1.next()) {
       byte[] bytearray = new byte[4096];
int size=0;
InputStream image;
image = rs1.getBinaryStream(1);
response.reset();
response.setContentType("image/gif");
while((size=image.read(bytearray))!= -1 ){
 response.getOutputStream().write( bytearray,0,size);
}
response.flushBuffer();
image.close();
rs1.close();

this is the servlet that i am trying to call from another servlet using

out.println("<img src='/worst?id=5'>");

but i am not getting the image . please help me out.

It's possible that URL doesn't point to your servlet correctly. It's possible that the SQL query doesn't select any rows. It's possible that your database code throws an exception. I'm sure there are other possibilities. So given all of that, it would help if you explained exactly what you see instead of just saying you don't get the image. You might also want to review the server logs and debug your servlet code to see what, if any, lines of code are being executed.

As Paul Clapham said, "explained exactly what you see instead of just saying you don't get the image".

Check the url that your method is creating. It is possible that this url is poiting to some invalid link.

As Paul pointed out, most likely the URL is invalid. Do a View Source of the page and cut/paste the URL of the image tag into the browser address bar. Does the image appear? If not, the URL is not correct.
