BCP data into a file using Runtime class

Question

Hi,
     I have a problem in using the Runtime class.
I am trying to bcp a table's data into a file.I am working on a Unix environment.
My bcp is not getting completed fully.The total records to be bcped is 1 million,but only one lakh records is getting bcped and then it hangs up..But if i issue the bcp command from my telnet session it is bcping it to the file without any problem.Can anyone help me out on how to overcome this..
Is there anything specific with Runtime class..I am pasting the code that i tried out below.
String l_s_bcpQuery="bcp mubstage.dbo.HousingUnitSampleMarket out /dun/d3nmb0/mariaps/subracheckprototype -c -t~ -Umariaps -Prykwz5ba -SD3NMB_MUB";
try{
Runtime time=Runtime.getRuntime();
Process p=time.exec(l_s_bcpQuery);
p.waitFor();
System.out.println("The exit value is:"+p.exitValue());
}catch(Exception ioe){
     ioe.printStackTrace();
     System.out.println("IOException"+ioe.getMessage());

you might need to capture the stout & sterr from the process. see http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Process.html, or many other similar questions on this forum.
try this:
try{
Runtime time=Runtime.getRuntime();
Process p=time.exec(l_s_bcpQuery);
BufferedReader stout = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader sterr = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String out = stout.readLine();
String err = sterr.readLine();
while((out != null)||(err != null))
if(out != null)
System.out.println(out);
if(err != null)
System.err.println(err);
out = stout.readLine();
err = sterr.readLine();
int exit_value = p.waitFor();
System.out.println("The exit value is:"+ exit_value);
}catch(Exception ioe){
ioe.printStackTrace();
System.out.println("IOException"+ioe.getMessage());
}
