JCIFS and Tomcat

[erik]

Hello,

I am trying to read a web page from within a tomcat servlet, using my
company Proxy server (NTLM). When I try to do this, I get a 407. What
means that my servlet did not pass the proxy. When I run the program
stand alone every thing works fine. Can someone help me with this.

Here some sample code:

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Properties;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import jcifs.Config;

public class AccessWebService extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.getWriter().print(readWeb()); //result: HTTP 407
}

public static void main(String[] args) throws IOException {
AccessWebService service = new AccessWebService();
System.out.print(service.readWeb());
//result: requested web page
}
public String readWeb() throws IOException {
enableProxy();
byte[] response = read(new URL("http://groups.google.com/"));
disableProxy();
return new String(response);
}

private byte[] read(URL url) throws IOException {
HttpURLConnection httpConn =
(HttpURLConnection)url.openConnection();

byte[] result = getResponse(httpConn);
httpConn.disconnect();

return result;
}

private byte[] getResponse(HttpURLConnection httpConn) throws
IOException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
transfer(httpConn.getInputStream(), out);

return out.toByteArray();
}

private void transfer(InputStream in, OutputStream out) throws
IOException {
byte[] buffer = new byte[2048];
int bytesRead = 0;

while ((bytesRead = in.read(buffer)) > -1) {
out.write(buffer, 0, bytesRead);
}

in.close();
}

private void enableProxy() {
Config.setProperty("jcifs.smb.client.domain","mydo main");
Config.setProperty("jcifs.smb.client.username","my username");

Config.setProperty("jcifs.smb.client.password","my password");

Properties systemProperties = System.getProperties();

systemProperties.setProperty("http.proxyHost","myp roxyhost");

systemProperties.setProperty("http.proxyPort","myp roxyport");

Config.registerSmbURLHandler();
}

private void disableProxy() {
Config.setProperty("jcifs.smb.client.domain", "");
Config.setProperty("jcifs.smb.client.username", "");
Config.setProperty("jcifs.smb.client.password", "");

Properties systemProperties = System.getProperties();
systemProperties.setProperty("http.proxyHost", "");
systemProperties.setProperty("http.proxyPort", "");
systemProperties.setProperty("java.protocol.handle r.pkgs",
"");
}
}
