"INFO: Discarding unexpected response: HTTP/1.1 100 Continue" error

[jumunk]

I wrote a program that sends a cradit card authorization request to TransFirst.
I can successfully send a file with the authorization information and receive a
response. My problem is that I also get this as an output "INFO: Discarding unexpected response: HTTP/1.1 100 Continue". Does anyone know how to get rid of this output? Thanks in advance.

My code is:

import java.io.*;
//import java.util.*;
import java.security.*;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.EntityEnclosingMethod;
import org.apache.commons.httpclient.methods.PostMethod;


public class tfirstComm {

	static String testURL = "https://ePaysecure1.transfirst.com/elink/authpd.asp";	
	static String hostURL = "https://ePaysecure1.transfirst.com/elink/authpd.asp";
	
	
	 public static void main(String args[]) throws Exception
	  {

		  // Display usage parameters
		  if (args.length != 1)
		  {
			  System.err.println("usage: java tfirstComm orderID");
			  System.exit(0);
		  }


			try
			{
				
				String fileRequest = args[0];
				
				
				String fileResponse = "A"+fileRequest+".ret";
				
				File tempReta = new File(fileResponse);
				BufferedWriter wrReta = new BufferedWriter(new FileWriter(tempReta));
				File tempAuth = new File("TR" + fileRequest + ".aut");

				// Turn on SSL capabilites//////////////////////////////////////////		
				Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

				// Create a TCP connection & POST the XML temp file
				String workURL = "";
				workURL = hostURL;
				

				PostMethod post = new PostMethod(workURL);
				post.setRequestBody(new FileInputStream(tempAuth));
				//post.setRequestHeader("Host:", "htt://epay.transfirst.com");

				//post.setRequestHeader("POST",hostURL,"false");
				post.setRequestHeader("Pragma", "No-Cache");
				post.setRequestHeader("Stateless-Transaction", "true");
				post.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
				
				if (tempAuth.length() < Integer.MAX_VALUE)
				{
					post.setRequestContentLength((int)tempAuth.length());
				}
				else
				{
					post.setRequestContentLength(EntityEnclosingMethod.CONTENT_LENGTH_CHUNKED);
				}

				HttpClient httpclient = new HttpClient();
				int result = httpclient.executeMethod(post);
				//System.out.print(post.getResponseBodyAsString());
				// Write the response to a temp file
				wrReta.write(post.getResponseBodyAsString());
				

				// Close the TCP connection, temp files, & db connection
				post.releaseConnection();
				wrReta.close();

			}

			catch (IOException e)
			{
				System.err.println("Communication Error - Retry the Authorization");
				System.out.println(e.toString());
				System.exit(-1);
				e.printStackTrace();
			}
			catch (Exception e)
			{
				System.out.println(e.toString());
				e.printStackTrace();
				System.exit(1);
			}
	  }
	

}

you can change logging level from INFO to WARN,
or log into a file instead of console.

first find out which logging library in use.
log4j or java's logging API are known ones.
