how to call servlet from java program

Hi,
I have a servlet which is deployed in weblogic server, I need to call this servlet from standalone JAVA program, can some one help in this and how to pass request,response parameters to servlets and taking back the response from servlet.

Thanks in advance

A better approach would be to factor the common processing out into a separate class that can be used both by the servlet and your stand-alone app.

servlet is in some other server .. which we don't have any access to modify it .. requirement is i need to call that servlet by passing a XML doc object and the servlet will send the result in xml format ..

Then you could check out the URL and URLConnection classes. Or make it easy on yourself and check out HttpClient from the Jakarta project.

check this,

package com.client;
 
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
 
import weblogic.net.http.HttpURLConnection;
 
public class TestClient {
 
/**
 * @param args
 */
public static void main(String[] args) {
String a="http://localhost:7001/WebApp/HelloWorld";
URL url=null;
try {
url = new URL(a);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
HttpURLConnection h=new HttpURLConnection(url);
try {
h.setDoOutput(true);
String request="test"; 
h.setDoInput(true);
h.setRequestMethod( "POST" );
h.setRequestProperty("Content-Length", "" +Integer.toString(request.getBytes().length));
h.setUseCaches(false);
DataOutputStream out = new DataOutputStream( h.getOutputStream() );
out.writeBytes( request );
 
out.flush();
 
out.close();

BufferedReader reader = new BufferedReader( new InputStreamReader(h.getInputStream() ) );
String response = reader.readLine();
while( null != response )
{
System.out.println( response );
response = reader.readLine();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
 
}

Tried in weblogic, it works fine.
