Thanks for the reply.I used the following code and geting the below error
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
try
DefaultHttpClient http = new DefaultHttpClient();
final String username = "domain\\username";
final String password = "password";
UsernamePasswordCredentials c = new UsernamePasswordCredentials(username, password);
BasicCredentialsProvider cP = new BasicCredentialsProvider();
cP.setCredentials(AuthScope.ANY, c);
http.setCredentialsProvider(cP);
String urlString = "http://mymachine/ReportServer/Pages/ReportViewer.aspx?";
URL url = new URL(urlString);
HttpPost post = new HttpPost(url.toURI());
HttpResponse responseTest= http.execute(post);
System.out.println(" The statusline is"+responseTest.getStatusLine());
catch(Exception ex)
System.out.println("The exception is"+ex);
