Hi Murphy,
jYMSG has got the following structure
ymsg
|
--network
some java files (both ChallengeResponseV10.java and challenger.bin
are placed at this level)
|
--event
some java files
In ChallengeResponseV10.java file he is doing the following to load
challenge.bin file,
.......
.......
// -----Buffer for binary data, and resource filename
private static byte[] data;
private final static String BIN_FILE="challenge.bin";
// -----------------------------------------------------------------
// Load binary data tables as a resource from /ysmg/network/BIN_FILE
// -----------------------------------------------------------------
static
{ try
{ // -----Open stream to resource located next to this
class
Class v10 =
Class.forName("ymsg.network.ChallengeResponseV10");
DataInputStream dis = new
DataInputStream(v10.getResourceAsStream
(BIN_FILE));
data = new byte[dis.available()];
// -----Extra entry at end of offset table has entire
file size
if(data.length<TABLE_OFFSETS[TABLE_OFFSETS.length-1])
throw new Exception("Data too short?");
// -----Read binary data into array
dis.readFully(data);
dis.close();
}
catch(Exception e)
{ System.err.println("Error loading resource file:
"+BIN_FILE);
e.printStackTrace();
}
}
I don't understand why getResourceAsStream() failed to load the file
which is being present at the same directory level!
Then I tried removing challenge.bin in this location and moved to res/
raw folder of my Android project, even then no luck!
Please let me know if I have to change something to above code
correctly pick the file.
Thanks
