Java APIs

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...............
