problem writing ImageServlet?

[hasan khan]

if some body have time then only read my question as i am explaining my problem in detail.

i have a 2 websites named

a) http://www.site1.com
b) http://www.site2.com

in my site1 i have some jsp pages, and jsp have <img> tag.

<img src="images/myimage1.jpg">
<img src="images/myimage2.gif">

but site1 dont have folder images but it is at site2

i dont want to change my <img> tags to
<img src="http://www.site2.com/images/myimage1.jpg">
or to something else because i don't want to show any one that the images are coming from some other website.


so i have a created servlet named ImageServlet and its configuration in web.xml is like this :

<servlet>
<servlet-name>ImageServlet</servlet-name>
<servlet-class>com.mycompany.ImageServlet</servlet-class>
</servlet>
 
<servlet-mapping>
<servlet-name>ImageServlet</servlet-name>
<url-pattern>*.jpg</url-pattern>
</servlet-mapping>
 
<servlet-mapping>
<servlet-name>ImageServlet</servlet-name>
<url-pattern>*.gif</url-pattern>
</servlet-mapping>

i have mapped ImageServlet to jpg and gif files because i dont want to change <img> tags which more than 100 times in jsp pages in site1

so every request to jpg or gif files goes to ImageServlet

if the browser request for the image
http://www.site1.com/images/myimage1.jpg

servlet takes the request.getServletPath() in this case it is : /images/myimage1.jpg
and make url connection to site2 in this case : http://www.site2.com/images/myimage1.jpg

the servlet opens InputStream read the content of the image and send it back to the client.

now the problem starts here

whenever i type the url in the browser
http://www.site1.com/images/myimage1.jpg

my servlets doGet() is called for infinite time and the browser does not get any response

the code of my servlet :-

public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
{
 
String strServletPath = request.getServletPath();
response.setContentType(application.getMimeType(strServletPath));

System.out.println("\nServletPath :" +strServletPath);
 
URL url = new URL("http://www.site2.com" +strServletPath);
System.out.println("\nurl " +url);

URLConnection con = url.openConnection();
con.setUseCaches(false);
 
System.out.println("urlcon " +con);
 
// Note : after this servlet does not executes 
 
BufferedInputStream in = new BufferedInputStream(con.getInputStream());
System.out.println("\nin " +in);
BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
System.out.println("\nout " +out);

byte b[] = new byte[8];

while(in.read(b) != -1)
{
//System.out.println("bytes : " +new String(b));
out.write(b);
out.flush();
}

out.close();
in.close();
}

in my server console i can only see lines printed till urlcon
please help what is the problem or mistake here.
