Neurons Needed

Finally, at exactly 4:00 AM, I was able to build the rewritten AES code from desktop source program to its mobile counterpart. I was excited because I got rid several problems such as non-existence of java.IO.File in J2ME, midlet user interface refamiliarization, and importantly, elimination of file writing.

Press Run.
Input Username, Phone number, Password. OK
Press Send.
Select file to encrypt and to decrypt. OK
Press Select.

java.lang.OutOfMemoryError!

No!

As of 4:43 AM, after taking a nap, pagkatapos magkasama kahit sa panaginip lamang, I inferred that it was caused by creating array of int whose size is Integer.MAX. Good luck, talaga!

Yes!

It works!

Importing:

1. Create New Project
2. Set a Project Name
3. Create Project from an Existing Source
4. Browse directory
5. Next
6. Add necessary jar files and libraries
7. Finish

Execution:

1. Run >> Run...

Same Mill Bee

Seelvester, a popular cat I suppose and ancestor of Hamster referenced the same source code from these URL's

http://java.sun.com/products/java-media/jmf/2.1.1/solutions/AVTransmit2.java
http://java.sun.com/products/java-media/jmf/2.1.1/solutions/AVReceive2.java

Ma'm Susan once told us these classes work. Yes, I believe so but these works for two desktop PCs. Seelvester Project wasn't able to program the MIDlet version of these RTP Transfer. They only worked on the cryptography in MIDlet.

Mahaba-habang inuman pa ito!

Yey!

Our pet HAMSTER can already

... play WAV audio. (tada!)
... play MIDI audio. (always something there to remind me...)
... play MPG video na rin (over the network pa! http!)

Ew! RTP na!

'c' in Java

Hey, guys! I finally figured how to control that pest, I just imported the class this way:

import javax.microedition.media.control.*;

Imagine! That little 'c' makes a big difference!

Well, I'm continuing exploring the magic of 'c' in Java.

By the way, I got the bigger C in a tutorial. That page should be edited! Er!

Sinfinity Webapp Update

The web application has been rewritten from static HTML to JSP, though progress has been halted -- we still haven't obtained the database from the other group.

The webapp has been hosted on Ia's domain, though it seems that JSP capability isn't switched on by default by Filcode. We're contacting them now.

More updates soon.

Can't Control the Video Control, Er

I had already installed both WTK 2.2 and WTK 2.3 thinking that the version caused it. But, no!

I'm not sure if the selected media or device has no video capability. I'm assuming that running the MIDlet in an emulator will go perfectly when emulator is supposed to be "ideal" phone.

The compiler is not happy when it cannot find the class Video Control in javax.microedition.media.Control when it is supposed to be there. The jar is not broken, for sure!

Wah! I'm trying the AudioControl instead!

poor man's key generation

jonas, ito muna gamitin mo for key generation... although we're still deciphering if the generated strings/bytes are valid keys (see last part below; pero nakaspecify naman sa method na 1024-bit ang keysize eh).

Example File: KeyTools.java
Output files: Found here.
Algorithm: DSA (not sure if DH is included by default.)

[public|private][n], where n:
1=whole key instance is written to file
2=key.getEncoded() is written to file, returns byte[]
3=String conversion of (2) is written, returns String

character count of public vs private [n] files in Notepad++:
1=700 vs 594 (doesn't help)
2=471 vs 362
3=732 vs 543
