Subject: [users@httpd] HttpURLConnection - java.net.ConnectException:
 Connection timed out


Dear all,

   I am usging Apache-Tomcat 5.5.20 and Axis 1.2 RC.
I am invoking the web services method by my java client program.

In SoapBindingImpl class i have written a Implementation method
sendAndReceive().
sendAndReceive method code is --

    public String sendAndReceive(String sRequest, String sMode)
    {

	StringBuffer sbResponse = new StringBuffer();
	URL url = null;
		
	try
	{
		sbResponse = new StringBuffer();
		String _sServerURL =_sLocalServerPath;				
            	url = new URL(_sServerURL+"/wsTestServiceServlet");  //Servlet
- where business Implementation code is written.
            	HttpURLConnection conn =
(HttpURLConnection)url.openConnection();    //
sun.net.www.protocol.http.HttpURLConnection {rt.jar}
            	conn.setRequestMethod("POST");
            	conn.setDoOutput(true);
            	conn.setDoInput(true);

            	PrintStream outStream = new
PrintStream(conn.getOutputStream());            ==> java:140 from Exception
stack
            	outStream.print("request="+URLEncoder.encode(sRequest));
            	outStream.print("&BIZ_ACTION_MODE=" +sMode);           
            	outStream.close();

		BufferedReader rd = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
			
		String line;

		while ((line = rd.readLine()) != null) 
		{
			sbResponse.append(line);
		}
			
		rd.close();			

	} catch (MalformedURLException e)
	{
		sbResponse.setLength(0);
		sbResponse.append(e.getMessage());
		e.printStackTrace();
	} catch (IOException e)
	{
		e.printStackTrace();
		sbResponse.setLength(0);
		sbResponse.append(e.getMessage());
	}
		
	return sbResponse.toString();
	
    }
 
>From this method i am getting Connection Time out Exception.
On this line program is hanged :
PrintStream outStream = new PrintStream(conn.getOutputStream());

Please see Exception ==

Problem is something related to HttpURLConnection with getOutputStream() and
getInputStream() ..

Or it is due to some configuration of Tomcat. 

I am not able to figure it out what adjactly  the Problem is.

1. is it due to HttpURLConnection with getOutputStream() and
getInputStream().
2. is it due to wsTestServiceServlet Servlet ==> ( url = new
URL(_sServerURL+"/wsTestServiceServlet");)
3. is it due to some configuration file in Tomcat.
4. As i am thinking it's not a Axis problem.


please help me out...............


Regards
Santosh Kumar Sharma
