Dang, Netscape, here it is again!

I'm converting an application from 3.5.1 to 4.0 using tops.exe. Now
the
occurences of
ImmutableHashtable are now converted to NSDictionary.
Unfortunately the constructor ImmutableHashtable(File aFile) has been
vanished (after
it NEVER appeared in 3.5.1- documentation) and wether NSDictionary
(neither NSMutableDictionary)
offers a constructor with such parameter.
Does anybody have an idea how to convert this constructor resp.
workaround it ?
I did something like this, most of it was in one of the examples
that came with WO 4.0. You could probably do it someway easier
than this if you looked into it.
public static NSDictionary getDictionaryFromFile (String
filenameWithPath) {
try {
filenameWithPath.replace('\\', '/'); // Fighting NT
File file = new File(filenameWithPath);
return (NSDictionary)objectFromPListFile(file);
} catch (Exception e) {
System.err.println("Cannot load dictionary from file" + e);
return null; // Return null, let them handle it there.
} // end try
} // end getDictionaryFromThisFile
public static Object objectFromPListFile(File file) throws
IOException {
return
NSPropertyListSerialization.propertyListFromString(stringFromFile(file));
}
public static String stringFromFile(File file) throws IOException {
if (file==null)
throw new IOException("null file");
int size=(int) file.length();
FileInputStream fis=new FileInputStream(file);
byte [] data = new byte[size];
int bytesRead=0;
while (bytesRead<size)
bytesRead+=fis.read(data,bytesRead,size-bytesRead);
fis.close();
return new String(data);
}
BTW, the application I'm converting is the DodgeLiteJava demo
application that came with WO 3.5.1. There is code used in the demos
which was neither documented nor is taken it over. Reminds me of the
"undocumented-Windows 3.1"-times.
Thanks
