Thanks for your suggestions!
Just to confirm my understanding of your suggestion, I tried out the
following:
// Start of example class
import java.io.*;
import java.util.*;
public class PropTest2
{
public static void main (String args[])
{
File libDir = null;
try {
libDir = new File(
System.getProperty("java.home") +
File.separatorChar + "lib");
}
catch (SecurityException e) {
System.out.println("SecurityManager prevents access to system
properties.");
return;
}
File propFile = new File(libDir, args[0]);
System.out.println("Expecting properties in: "+propFile.getPath());
Properties p = new Properties();
try {
p.load(new FileInputStream(propFile));
}
catch (Exception e) {
System.out.println(e.toString());
return;
}
p.list(System.out);
}
}
// End of example class
This works, but I was wondering if there was anyway to access the host
platform's environment variables, not just those of the JVM (with a few
vendor-specific properties)? I had a look around the System and Runtime
classes in java.lang, but didn't see any obvious way of getting at them.
This might be a bit "cleaner", or simpler for an administrator with little
knowledge of Java, because -- for a start -- it's not always obvious which
JVM is used by a web app container (yes, I know it's possible to find out,
but the whole point of this thread is to simplify deployment).
I had also thought about using the webapp's server's lib dir, as you
suggested, but wasn't sure of a way to construct server-independent
pathnames towards the "lib" folder of the server.
As for your classpath suggestion, do you mean reading the classpath system
property ("java.class.path"), then looking in each path in the list for the
specified file?
Other than that... which address do you believe would be most effective for
whining to Sun...?
In any case, thanks for your suggestions. Much appreciated!
