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);
}
