memory problem regarding creating jar files

[gaziani007]

Hello Develpers,
I am a j2me developer and i want to ask u to help me out in a problem. The problem actually is:

I am creating a jar with the code only there is no problem and the memory is say 40KB.
I am creating a jar witht the images there is no problem and the memory is say 15 KB
when i combine the images and the jar together the jar file should be 60Kb but it shows extra 8 Kb to the jar file. Note that I am using gif's, png's and jpeg's format

Please I'll appreciate ur attention

regards

Well, jar files also have a catalogue of the files and directories in them, so if you have many of them each will add some overhead to the total. *KB sounds like a bit much, though.

Things you can do:
* Obfuscate the code to make it smaller.
* Put everything in the root directory.
* Combine several images into one file (you save twice, once for the jar's catalogue overhead, and once for the image header's overhead).
* Use png optimizers and such software that strips out unnecessary parts of the images to make them smaller.
* Merge class files into one class that combines the functionality.

Dear shmoove,
Thanx for paying attention to my problem. Plz help us in extracting images from a single file as i havent done that thing before. If u have some code snippet or some script regarding that plz help me by that. I'll really appreciate your help.
