JAVA DNR Help

DavidMusser

Does anyone have a DNR written in java that is either reading STDIN (so I can parse later) or parsing STDIN. I tried

public class OpenDeployTest
{
private static BufferedReader stdin = new BufferedReader( new InputStreamReader( System.in ) );
...
..
..
public static void main (String[] args) {

..
..

try
{

String input = stdin.readLine();
out.print(input);

I just used psudo code.. but there were the main parts. If I change the output to be sytem.out.println... and run this from the command line whatever I enter is passed in as stdin. When I run through the dnr it's not.

i'm wondering if I need to do something other than System.in or if I need to tell it system.memory in or something...

Ideas?

David,

Per your request I am posting my solution to getting the manifest from a Java program. I actually started with the code snippet you posted and worked from there:

import java.io.*;

public class XMLWriteToFile
{

static InputStreamReader converter = new InputStreamReader(System.in);
static BufferedReader in = new BufferedReader(converter);

public static void main(String[] args)
{
String xmlStream = XMLWriteToFile.getManifest();
if (xmlStream != null)
{
try
{
FileWriter out = new FileWriter("e:\\manifest.xml");
out.write(xmlStream);
out.close();
}
catch (IOException ioe)
{
System.out.println("Bummer, its broken.");
System.exit(2);
}
}
else
{
try
{
FileWriter out = new FileWriter("e:\\manifest.xml");
out.write("There were no arguments");
out.close();
}
catch (IOException ioe)
{
System.out.println("Bummer, its broken.");
System.exit(4);
}
}
}

// Read the manifest from standard system input
public static String getManifest()
{
try
{
String manifestString = null;
String record = null;
boolean firstTime = true;
while ((record=in.readLine()) != null)
{
if (firstTime)
{
manifestString = record;
firstTime = false;
}
else
{
manifestString += record;
}
}

return manifestString;
}
catch (Exception e)
{
System.out.println("getString() exception, returning empty string");
return null;
}
}
}
