I have a jar (cfg.jar) which contains a configuration file (cfg.txt)
for an application. The format of the configuration file is such that
the '#' char at the beginning of the line indicates comments to be
ignored. The uncommented lines contain key value strings for the
application. Below is the first few lines of the expanded
configuration file
#****************************************************
# Lines beginning with "#" char are comments.
SEQUENCE_SELECT_DISAPPEAR_PAUSE=500
#****************************************************
# Pause duration after sequence finishes
SEQUENCE_SELECT_REAPPEAR_PAUSE=250

The following code outputs no lines of the compressed cfg.txt file.
When the System.out.println line is uncommented in main, the output
looks as follows:

false
#****************************************************
true

public class ReadJarCfg
{
public static void main(String[]args){
try{
MyJarLineReader reader = new MyJarLineReader();
String line = reader.readLine();
while(line != null){
System.out.println(line == null);
if( line.startsWith("#") ){
//System.out.println(line);
line = reader.readLine();
System.out.println(line == null);
}
else{
System.out.println(line);
line = reader.readLine();
}
}
}catch(IOException e2){System.out.println("Exception caught");}
}
}

class MyJarLineReader
{
String cfgJar = new String("C:\Program
Files\LptJarResrcs\ReadJar\cfg.jar");

private File lptJar = new File(cfgJar);
private JarFile jarFile = null;
private ZipEntry cfgTextZip = new ZipEntry("cfg.txt");
private InputStream iStream;

public MyJarLineReader()throws IOException{
jarFile = new JarFile(lptJar, true, jarFile.OPEN_READ);
iStream = jarFile.getInputStream(cfgTextZip);
}

public String readLine() throws IOException
{
BufferedReader reader = new LineNumberReader( new
InputStreamReader(iStream) );
return reader.readLine();
}
}

I have expanded the cfg.jar file to confirm that it is not corrupted.

Thanks in advance for any help
