Help with download servlet

[Duran Harris]

Hi all,

I'm having trouble getting this servlet to run...
when I reguest http://localhost:8080/Duran/download my browser just hangs and say:waiting for localhost..
Please take a look at the servlet and DD for me....

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<servlet>
	<servlet-name>download</servlet-name>
	<servlet-class>Duran.downloadServlet</servlet-class>
</servlet>
<servlet-mapping>
	<servlet-name>download</servlet-name>
	<url-pattern>/download</url-pattern>
</servlet-mapping>
</web-app>

package Duran;
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.*;

public class downloadServlet extends HttpServlet
{

public void doGet(HttpServletRequest request,HttpServletResponse response)throws IOException,ServletException
{

response.setContentType("image/jpeg");
ServletContext sc = getServletContext();
int read=0;
InputStream sis=sc.getResourceAsStream("/smiley.jpg");
byte[] data=new byte[4495];
OutputStream sos =response.getOutputStream ();
while((read=sis.read(data))!=-1)
{

sos.write(data,0,read);

}
sos.flush();
sos.close();



}
}

The smiley.jpg is a peer to WEB-INF.

Where did you place this servlet class in your deplyoment env.

[kashif bashir]

try this code.

try {
StringBuffer fileHeader = new StringBuffer();
fileHeader .append("inline");
fileHeader .append("; filename=");
fileHeader .append("file.jpeg");

if(pdfBytes!=null && pdfBytes.length>0) {
response.setHeader("Cache-Control", "max-age=30");
response.setContentType("image/jpeg");
response.setHeader("Content-disposition", fileHeader .toString());
response.setContentLength(imageBytes.length);
response.getOutputStream().write(imageBytes, 0, imageBytes.length);
} else {
response.getOutputStream().print("
No File Found Related Client.");
}

} catch (Exception e) {
e.printStackTrace();
}

The servlet is in WEB-INF/classes.

Running that code produces:

downloadServlet.java:34: cannot find symbol
symbol : variable pdfBytes
location: class Duran.downloadServlet

[kashif bashir]

rename pdfBytes to your imageBytes.

[Duran Harris]

That code doesn't seem to help..
Am I requesting the right URL for the mapping?:
http://localhost:8080/Duran/download

[kashif bashir]

you are not assigning bytes rather declaring

byte[] data=new byte[4495];

load bytes from your image resource and assign to data in try catch block.

ommit other code outside try catch.

No I think I have messed up my tomcat-users file...Even if I request a JSP it just hangs.
Here is tomcat-users:

<?xml version='1.0' encoding='utf-8'?>

What is missing?
